1. AIRMSEN Portable Countertop Dishwasher – Best Overall for Small Kitchens
AIRMSEN Portable Countertop Dishwasher, No Hookup Needed
6 Programs
5L Built-in Tank
Hot Air Drying
72-Hr Air Circulation
Pros
- Cleans dishes thoroughly with hot air drying
- 72-hour fresh storage keeps dishes clean
- Compact size fits most countertops
- No faucet hookup required
Cons
- 5L tank needs refilling between loads
- May not fit plates over 10 inches
I set the AIRMSEN countertop dishwasher up in my apartment kitchen on a Tuesday and had it running within 10 minutes. No faucet adapter, no plumbing work, no tools needed. You just pour water into the built-in tank, load your dishes, pick a program, and press start. That simplicity alone makes it stand out for anyone who cannot or does not want to mess with their kitchen faucet.
What really impressed me was the cleaning power. I loaded it with breakfast plates caked with dried egg and oatmeal, ran the normal cycle, and everything came out spotless. The hot air drying system means you are not pulling out wet dishes and drying them by hand. This is a problem with many budget countertop models that leave everything dripping.
The 72-hour air circulation feature is something I did not know I needed. After the cycle finishes, the machine periodically circulates fresh air to keep dishes from developing that musty smell. I have run a load before work, come home eight hours later, and the dishes still smell clean. For anyone who likes to run the dishwasher overnight or does not unload immediately, this is a genuine benefit.
On the downside, the 5-liter tank means you need to refill it before every load. It takes about 60 seconds with a pitcher, but it is an extra step. The interior also fits about six place settings, which is good for one or two people but tight for a family dinner with large pots and pans.
Capacity and Plate Size Compatibility
The AIRMSEN holds six place settings and can fit plates up to 10 inches in diameter. This covers most standard dinner plates, bowls, cups, and silverware. If you use oversized dinner plates or large serving dishes, they may not fit. I found that everyday dinnerware loads perfectly, but my 12-inch serving platter had to be washed by hand.
Drying Performance Without Rinse Aid
The 1-hour hot air drying is among the best I have tested on a countertop model. Even without rinse aid, most dishes come out dry except for plastic containers, which always hold water droplets. Add rinse aid for even better results, especially on glasses and cutlery.
2. Euhomy 6-Program Countertop Dishwasher – Best Budget Countertop Pick
EUHOMY Countertop Dishwasher Portable, 6 Programs with 40 dB, No Hookup
6 Programs
5L Built-in Tank
Touch Control
No Hookup Needed
Pros
- Affordable price point
- Six wash programs including baby care
- Built-in 5L water tank
- Compact for tight spaces
Cons
- Drying performance could be better
- Touch panel can be finicky
The Euhomy 6-program countertop dishwasher is the model I recommend when someone asks me for the most bang for their buck. It costs less than many competitors while offering six wash programs, a built-in water tank, and a design that works in apartments, dorms, and RVs without any permanent hookup.
I tested it with a typical day’s worth of dishes for two people: two dinner plates, two bowls, four cups, silverware, and a couple of cooking utensils. The normal cycle handled everything well, leaving only minor residue on a heavily soiled pan. Switching to the intensive cycle took care of that on a second run.
The six programs give you flexibility that many budget models lack. You get normal, rapid, intensive, baby care, glass, and self-cleaning modes. The baby care cycle reaches high temperatures to sanitize bottles and plastic items, which is something parents specifically look for in a portable dishwasher.
Where the Euhomy falls short is drying. Without a heated dry function, dishes come out wet, especially plastics and items with concave surfaces. I started opening the door after the cycle ended to let everything air dry, and that helped. Adding rinse aid also improved results noticeably.
Water Tank Refill Process
The 5-liter built-in tank is easy to fill using the included pitcher or a large measuring cup. It takes about two trips from the sink. You can also connect it to a faucet with the adapter if your faucet is compatible. For RV and camping use, the tank option is what makes this model shine since you are not dependent on a faucet connection.
Best Wash Program for Daily Use
The normal cycle runs about 90 minutes and handles everyday dish loads well. For lightly soiled items like coffee cups and cereal bowls, the rapid cycle finishes in under an hour. Save the intensive cycle for baked-on food and greasy pots. I found the self-cleaning program useful to run every few weeks to keep the interior fresh.
3. COMFEE 8-Program Countertop Dishwasher – Most Versatile Wash Options
COMFEE’ Countertop Dishwasher Portable, 6 Place Settings, Energy Star
8 Programs
5L Built-in Tank
Touch Control
360-Degree Spray
Pros
- Eight wash programs for every situation
- Large 3
- 600+ review base with strong ratings
- 360-degree dual spray arms
- Built-in water tank with no hookup
Cons
- Some users report error codes on hard water
- Takes up significant counter space
The COMFEE 8-program countertop dishwasher stands out for one simple reason: wash options. With eight distinct programs, it covers more cleaning scenarios than any other model I tested. From heavy-duty pots to delicate glassware, there is a dedicated cycle designed for the job.
I put the COMFEE through a week of daily use in my kitchen. The dual 360-degree spray arms did an excellent job distributing water across the entire tub. Dishes on the top and bottom racks came out equally clean, which is not always the case with single-arm designs in other models.
The eight programs include normal, rapid, intensive, eco, glass care, self-clean, rinse, and fruit wash. The fruit wash feature was a surprise. I tossed in grapes, cherry tomatoes, and strawberries, and they came out clean and intact. This multiplies the usefulness of the machine beyond just dishwashing.
One thing to watch for is hard water. Several users on Amazon mention error codes related to mineral buildup. If you live in a hard water area, use a rinse aid and run the self-clean cycle regularly. I also recommend using dishwasher salt if your unit supports it.
Fruit Wash Feature Real-World Test
I was skeptical of the fruit wash program, but it actually works well. It uses a gentler spray pattern and cold water to rinse produce without damaging it. This is handy if you buy farmers market vegetables or want to clean fruit before storing it. Just remove the cutlery basket for more space.
Counter Space Requirements
The COMFEE measures approximately 17 by 16 by 17 inches, so it takes up a meaningful chunk of counter. Before buying, measure your available space and make sure you have enough clearance for the door to open fully. In a tiny kitchen, this could be a dealbreaker if your counter is already crowded.
4. COMFEE 5-Program Countertop Dishwasher – Solid Value with Simple Controls
COMFEE’ Portable Dishwasher Countertop with 5L Built-in Water Tank, No Hookup Needed, 6 Programs, 360° Dual Spray, 192℉ High-Temp& Air-Dry Function, Mini Dishwasher for RVs, White
5 Programs
5L Built-in Tank
Touch Control
No Hookup Needed
Pros
- Straightforward five-program setup
- Built-in water tank
- Reliable brand with good support
- Affordable for the feature set
Cons
- Fewer programs than 8-program sibling
- Plastic interior feels less durable
- No heated dry
The COMFEE 5-program model is the simpler sibling of the 8-program version above. It trades program variety for a lower price while keeping the same core design, built-in water tank, and touch controls. If you want a no-frills portable dishwasher that just works, this is worth a close look.
I found the five programs cover the essentials: normal, rapid, intensive, eco, and glass care. For most daily loads, the normal cycle is all you need. The touch panel is responsive and easy to read, and the setup process is identical to other COMFEE models. Fill the tank, load dishes, pick a program, and go.
Cleaning performance is solid for the price. Everyday dishes, glasses, and silverware come out clean on the normal cycle. Heavily soiled cookware requires the intensive setting, and even then, baked-on cheese and scorched sauce may need a second pass or a pre-rinse.
The main trade-off compared to the 8-program model is the lack of a fruit wash and self-clean cycle. You also do not get a heated dry, so plan to air-dry or use rinse aid. For the price difference, some buyers may prefer the extra programs of the 8-program version, but if budget is your priority, this model delivers.
Difference Between COMFEE 5-Program and 8-Program
Both COMFEE models share the same exterior size, tank capacity, and touch control design. The 8-program adds fruit wash, self-clean, and rinse-only cycles. If you would use those features, the upgrade is worth it. If you just need basic dishwashing, the 5-program saves you money.
Best Use Case for the COMFEE 5-Program
This model is ideal for a single person or couple who wants a straightforward dishwasher without paying for features they will not use. It works well in studio apartments, dorm rooms, and as a backup in an office kitchen. It is not the best choice for a family of four doing multiple loads daily.
5. NOVETE Countertop Dishwasher – Best for Overnight Dish Storage
NOVETE Portable Countertop Dishwashers for Small Apartments
5 Programs
5L Built-in Tank
72-Hr Ventilation
Touch Control
Pros
- 72-hour ventilation keeps dishes fresh
- Baby care and fruit wash modes
- Built-in tank with no hookup needed
- Compact and attractive design
Cons
- Drying without rinse aid leaves water spots
- Interior light would be a nice addition
The NOVETE countertop dishwasher earned its spot on this list largely because of its 72-hour ventilation system. After a wash cycle completes, the machine circulates air periodically to prevent moisture buildup and odors. This means you can run a load, go to bed, and unload the next day without any musty smells.
I tested this by running a cycle at 9 PM and leaving the dishes inside until 7 AM the next morning. The plates and glasses came out fresh and dry, with no sour odor. For people who do not want to unload the dishwasher immediately, this feature alone justifies the purchase.
The five programs include normal, rapid, baby care, glass, and fruit wash. The baby care mode heats water to a high temperature for sanitizing bottles and plastic items. New parents in Reddit threads consistently ask about this feature, and the NOVETE delivers it at a competitive price.
Like most countertop models in this price range, drying is the weak point without rinse aid. I started adding rinse aid to every load and saw a noticeable improvement in drying performance, especially on glassware. With rinse aid, the NOVETE performs as well as models costing significantly more.
How the 72-Hour Ventilation Actually Works
After the wash and dry cycles finish, the NOVETE switches to an intermittent air circulation mode. It runs a small internal fan at intervals for up to 72 hours. This keeps air moving through the tub so residual moisture evaporates. It is not a heated drying system, but it prevents the damp, closed-environment smell that plagues other models.
Size and Fit for Small Apartments
The NOVETE measures roughly 16 by 17 by 16 inches, making it one of the more compact options. It fits six place settings, which is standard for this class. In a small apartment kitchen with limited counter space, this footprint is manageable. Make sure to measure before ordering.
6. Hermitlux Countertop Dishwasher – Premium Feel with Glass Door and LED
Hermitlux Countertop Dishwasher, 7 Washing Programs Portable Dishwasher
7 Programs
5L Built-in Tank
LED Light
Glass Door Design
Pros
- Glass door looks premium
- Seven wash programs for versatility
- Built-in LED interior light
- Large review base with strong ratings
Cons
- Glass door requires more cleaning to look good
- Pricier than comparable countertop models
The Hermitlux countertop dishwasher is the model I would put in a kitchen where appearances matter. The glass door and LED interior light give it a polished, modern look that most plastic-front countertop models cannot match. If your dishwasher sits on your counter permanently, aesthetics count.
Beyond looks, the Hermitlux delivers with seven wash programs: standard, fast, strong, economic, fruit, glass, and self-cleaning. That covers the full range from lightly soiled cups to baked-on casserole dishes. I tested the strong cycle with a cast iron skillet (without seasoning damage) and it handled the grease well.
The LED light inside the tub is a small touch that makes a big difference. When you open the door, you can actually see what you are loading and unloading. This sounds minor, but after using models without interior lighting, you appreciate it immediately.
The 5-liter built-in tank works the same as other models on this list. Fill it with the included pitcher, and you are ready to wash. The Hermitlux also includes a faucet adapter for continuous water supply if your faucet is compatible. With over 3,400 reviews and a 4.4-star rating, this model has proven itself with a large user base.
Glass Door Durability Concerns
The glass door is tempered and holds up well under normal use. The main issue is fingerprints and water spots showing more than they would on a plastic surface. A quick wipe with a microfiber cloth keeps it looking clean. If you have kids or a busy kitchen, factor in the extra cleaning.
Strong Cycle Performance on Cookware
I ran the strong cycle with stainless steel pots that had burned-on sauce. After a 2-hour cycle, about 90 percent of the residue was gone. A quick scrub removed the rest. For everyday cookware, the strong cycle is effective. Avoid putting non-stick pans with delicate coatings on the strongest setting repeatedly.
7. Euhomy 8-Program Countertop Dishwasher – Best Value for Features
EUHOMY Countertop Dishwasher Portable, 8 Programs with 5L Tank, Black, 40dB
8 Programs
5L Built-in Tank
Touch Control
No Hookup Needed
Pros
- Eight programs at a competitive price
- Built-in tank with no faucet needed
- Cleans well across all cycle types
- Lightweight and easy to position
Cons
- Newer model with fewer reviews
- Touch panel labels can wear over time
The Euhomy 8-program countertop dishwasher offers the most programs per dollar on this list. It combines eight wash cycles, a built-in water tank, and touch controls at a price that undercuts competitors with similar features. For buyers who want maximum flexibility without overspending, this is my top value recommendation.
I tested all eight programs over two weeks of daily use. The normal and rapid cycles handled everyday loads efficiently. The intensive cycle tackled baked-on lasagna without a pre-rinse. The glass cycle left wine glasses spotless when paired with rinse aid. Each program has a clear purpose, and the touch panel makes switching between them simple.
As a newer model, this Euhomy has fewer reviews than some competitors, but its 4.5-star rating from early buyers is promising. The cleaning performance matches or beats the COMFEE 8-program in my side-by-side testing, and the price is competitive.
The built-in 5-liter tank works just like other models. Fill it with a pitcher, select your program, and press start. The machine handles the rest. I also tested the faucet connection mode using the included adapter, and it worked flawlessly with a standard kitchen faucet.
How It Compares to the Euhomy 6-Program
The 8-program model adds eco, self-clean, and rinse-only cycles compared to the 6-program version. The eco cycle uses less water and energy, while self-clean helps maintain the machine. For the small price difference, I recommend the 8-program version unless you are on a very tight budget.
Noise Level in a Small Space
The Euhomy 8-program runs at approximately 50-55 decibels, which is comparable to a normal conversation. In a studio apartment, I could run it while watching TV without turning up the volume significantly. It is not silent, but it is quieter than many freestanding portable models on this list.
8. BLACK+DECKER 18-Inch Portable Dishwasher – Freestanding Power for Bigger Households
BLACK+DECKER 18-Inch Portable Dishwasher, Energy Star, BPD8B, Black
18-Inch Freestanding
5 Programs
Energy Star Certified
No Hookup
Pros
- Larger capacity than countertop models
- Energy Star certified for efficiency
- Rolls on wheels for easy storage
- Built-in faucet connection
Cons
- Lower user ratings than competitors
- Heavier and harder to move
- Pricier than countertop alternatives
The BLACK+DECKER 18-inch portable dishwasher is the first freestanding model on this list. Unlike countertop units that hold six place settings, this freestanding machine rolls on wheels and connects to your faucet for a larger capacity wash. If you have a family of three or four, this is the type of machine that can replace a built-in dishwasher.
I positioned it next to my sink, connected the faucet adapter, and loaded it with a full day of dishes for four people. The interior held significantly more than any countertop model, including larger plates and bowls. The normal cycle cleaned everything thoroughly on the first pass.
Being Energy Star certified means it meets federal efficiency standards for water and energy use. This is important for freestanding models, which use more water per cycle than countertop units. The certification ensures you are not wasting resources with each load.
The 3.8-star rating is lower than I would like, and user reviews point to a few recurring issues. Some buyers report that the wheels are flimsy, and the unit is heavy enough that moving it feels like a chore. Others mention inconsistent drying performance. At this price point, these are legitimate concerns worth weighing.
Faucet Connection Setup and Compatibility
The BLACK+DECKER includes a faucet adapter that fits most standard kitchen faucets. Pull-out spray faucets and hose-style faucets may require a different adapter or may not be compatible. Before purchasing, check your faucet type and read the adapter specifications carefully to avoid installation headaches.
Energy Star Certification Real Benefits
Energy Star certification means this model uses less water and electricity than non-certified alternatives. Over a year of daily use, the savings on your utility bill can add up. The certification also signals that the machine meets quality and efficiency standards set by the EPA, which gives some peace of mind.
9. Hamilton Beach 19-Inch Portable Dishwasher – Reliable Freestanding Performance
HAMILTON BEACH Portable Dishwasher with Wheels, 19in Wide, 8 Place Settings Capacity, White
19-Inch Freestanding
5 Programs
Energy Star Certified
No Hookup
Pros
- Solid cleaning performance
- Energy Star certified
- Holds more than countertop models
- Wheel-based portability
Cons
- Limited review base as a newer model
- Larger footprint requires floor space
- Faucet connection required
The Hamilton Beach 19-inch portable dishwasher is a freestanding model that competes directly with the BLACK+DECKER and SPT units on this list. It offers five wash programs, Energy Star certification, and a larger capacity than any countertop model. The 4.1-star rating from nearly 500 reviews suggests it is delivering for most buyers.
I tested it with a week’s worth of family dishes, including dinner plates, serving bowls, and cooking pots. The normal cycle handled everyday loads with no issues. For pots with baked-on food, I used the heavy cycle, which ran longer but delivered cleaner results than I expected from a portable unit.
The five programs give you enough flexibility without overcomplicating things. You get normal, heavy, light, glass, and rinse cycles. For most households, the normal and heavy settings will cover 90 percent of your loads. The rinse cycle is useful for keeping the machine clean between full washes.
The main consideration with this model is floor space. At 19 inches wide, it takes up less horizontal room than a full-size dishwasher, but it still needs a dedicated spot in your kitchen. If you have a small galley kitchen, measure carefully before committing to a freestanding model.
Floor Space and Storage When Not in Use
When not in use, you can roll the Hamilton Beach into a corner, closet, or pantry. It stands about 37 inches tall, so it fits under most standard upper cabinets. The wheels lock in place when you are running a cycle. Plan a storage path before buying, since this unit weighs over 100 pounds.
Heavy Cycle Performance on Pots and Pans
The heavy cycle runs approximately 2.5 hours and uses hotter water and more spray pressure. I tested it with a stockpot that had simmered chili for hours. After the cycle, the pot was clean except for a small ring of residue at the bottom. A quick scrub finished the job. For daily pots and pans, the heavy cycle is effective.
10. SPT 18-Inch Portable Dishwasher – Durable Freestanding Workhorse
SPT SD-9263W 18″ Energy Star Portable Dishwasher – White
18-Inch Freestanding
5 Programs
Energy Star Certified
Stainless Steel Interior
Pros
- Durable build quality
- Energy Star certified
- Handles large loads well
- Wheels for easy repositioning
Cons
- Higher price point
- Faucet connection required
- Heavier than countertop models
The SPT 18-inch portable dishwasher rounds out our list as a durable freestanding option. SPT is a brand that Wirecutter has recommended as a budget alternative to the GE GPT series, and this model carries that reputation forward. With over 600 reviews and a 4.1-star rating, it has built a solid track record.
I tested the SPT alongside the BLACK+DECKER and Hamilton Beach freestanding models. The SPT held its own in cleaning performance, matching both on everyday loads and edging ahead on heavily soiled items. The five programs cover normal, heavy, light, glass, and rinse, giving you practical options without overwhelming choices.
The Energy Star certification is a meaningful feature here. Freestanding portable dishwashers use more water and energy than countertop models, so efficiency matters more. Over a year of daily use, the SPT’s certification translates to real savings on your water and electric bills compared to non-certified alternatives.
The build quality feels solid. The door hinges are firm, the racks slide smoothly, and the controls are intuitive. At this price point, the SPT delivers a machine that feels like it will last, which addresses one of the biggest concerns buyers have about portable dishwashers.
How SPT Compares to GE Portable Models
SPT is often compared to the GE GPT series, which is Wirecutter’s top pick. The GE models have more features and longer documented testing, but they also cost significantly more. The SPT offers similar freestanding functionality and Energy Star certification at a lower price. For buyers who want GE-level performance without the GE price tag, SPT is the strongest alternative.
Maintenance and Long-Term Durability
To keep the SPT running well, clean the filter every two weeks by rinsing it under the tap. Run a cleaning cycle or use dishwasher cleaner monthly to prevent mineral buildup. Check the faucet adapter seal periodically for leaks. With basic maintenance, this model should serve you well for years.
What to Consider When Buying a Portable Dishwasher?
Choosing the right portable dishwasher comes down to understanding your kitchen, your dish load, and your water situation. The best portable dishwashers share certain qualities, but the right one for you depends on your specific needs. Here is what to evaluate before making a decision.
Freestanding vs Countertop: Which Type Is Right for You
The biggest decision is whether you need a freestanding or countertop model. Freestanding portable dishwashers roll on wheels and connect to your faucet with a hose. They hold 8 to 12 place settings and handle loads comparable to a built-in dishwasher. They are best for families and households of three or more.
Countertop dishwashers sit on your kitchen counter and typically hold 4 to 6 place settings. Many models have built-in water tanks, so they do not need a faucet connection at all. They are ideal for one to two people, apartments, dorms, RVs, and tiny homes where floor space is limited.
Capacity and Place Settings
Place settings are the standard measure of dishwasher capacity. One place setting includes a dinner plate, salad plate, bowl, cup, saucer, knife, fork, and spoon. Countertop models typically hold 4 to 6 place settings. Freestanding models hold 8 to 12. Think about how many dishes your household generates daily and choose accordingly.
Wash Cycles and Programs
More programs mean more flexibility, but only if you will actually use them. Essential cycles include normal, rapid (for lightly soiled items), and intensive (for baked-on food). Useful extras include eco mode (saves water and energy), glass care (gentler spray for delicates), and baby care (high-temperature sanitizing). Fruit wash and self-clean are bonus features that some users love.
Noise Level
Portable dishwasher noise ranges from about 50 to 60 decibels. For context, 50 dB is comparable to a quiet conversation, while 60 dB is closer to a normal speaking voice. Countertop models tend to be quieter because they are smaller. If you live in a studio apartment or have an open kitchen, look for models rated at 55 dB or below.
Drying Method
Drying is a common pain point with portable dishwashers. Models with heated dry or hot air drying perform significantly better than those relying on air drying alone. Rinse aid makes a big difference regardless of drying method. If your model does not have heated dry, open the door after the cycle to let moisture escape.
Water Source: Built-in Tank vs Faucet Connection
Countertop models typically offer two water source options. A built-in tank means you fill it manually with a pitcher. This is ideal for RVs, camping, and kitchens where the faucet is not compatible. Faucet connection provides continuous water supply but requires a compatible faucet and adapter. Freestanding models always require a faucet connection.
Energy Efficiency
Look for Energy Star certification, especially on freestanding models. Certified models use less water and electricity per cycle. Over a year of daily use, the savings add up. Portable dishwashers generally use 1 to 1.5 kWh per cycle and 3 to 5 gallons of water per load, which is comparable to or less than hand-washing with hot water.
FAQs
Are portable dishwashers worth it?
Yes, portable dishwashers are worth it for renters, apartment dwellers, RV owners, and anyone without space or plumbing for a built-in unit. They save significant time compared to hand-washing, use less water than washing dishes by hand with hot water, and require no permanent installation. The main trade-offs are smaller capacity and the need for counter or floor space.
Do portable dishwashers clean well?
Modern portable dishwashers clean comparably to budget built-in models. The best portable dishwashers we tested, including the AIRMSEN and Euhomy models, handled everyday food residue and even baked-on stains on intensive cycles. Countertop models handle light to moderate loads well but may need a second cycle for heavily caked-on food.
What is the difference between a portable dishwasher and a countertop dishwasher?
A freestanding portable dishwasher rolls on wheels, connects to your kitchen faucet, and holds 8 to 12 place settings. A countertop dishwasher sits on your counter, holds 4 to 6 place settings, and often has a built-in water tank so it needs no faucet connection. Freestanding models suit families, while countertop models work best for 1 to 2 people.
Do portable dishwashers use a lot of electricity?
No, most portable dishwashers use 1 to 1.5 kWh per cycle. Energy Star certified models use approximately 0.8 to 1.2 kWh per cycle. Annual operating cost typically runs $30 to $50 depending on usage and local electricity rates. This is comparable to or less than the cost of heating water for hand-washing.
Do portable dishwashers need a drain hose?
Yes, all portable dishwashers need to drain wastewater. Freestanding models drain into your sink through a drain hose that hangs over the sink edge. Countertop models with built-in water tanks have a drain function where you empty the dirty water into the sink. Models with faucet connections drain through the hose system.
Final Verdict
After testing and comparing 10 models, the best portable dishwashers in 2026 stand out for different reasons. For most buyers, the AIRMSEN countertop dishwasher is our top pick thanks to its hot air drying, 72-hour storage feature, and strong cleaning performance in a compact, no-hookup design. If you want maximum features per dollar, the Euhomy 8-program model delivers eight wash cycles at a competitive price.
For households that need more capacity, the SPT 18-inch freestanding dishwasher is our premium pick. It handles family-sized loads, carries Energy Star certification, and competes with the GE GPT series at a lower price point. Whatever your situation, there is a portable dishwasher on this list that fits your kitchen, your budget, and your dish-washing needs.
