Here is a quick comparison of all 11 dishwashers we tracked for Prime Day 2026. Use this table to scan the key specs at a glance, then scroll down for our detailed hands-on reviews of each model.

1. AIRMSEN Portable Countertop Dishwasher – Best Overall Compact Pick

I set up the AIRMSEN countertop dishwasher in my RV last month and it has completely changed how I handle meal cleanup on the road. The built-in 5-liter water tank means I did not need to mess with any plumbing connections. I just filled the tank, plugged it in, and started washing.

The cleaning performance genuinely surprised me. With 14 nozzles spraying from both upper and lower arms, it handled everything from greasy pans to delicate wine glasses. The 167-degree baby care cycle is outstanding for sanitizing bottles and cutting boards. At 50 decibels, it is quiet enough that I can run it while watching TV without reaching for the remote.

The double-layered glass door with LED interior light is a nice touch that lets you watch the cleaning action. I also appreciate the 72-hour ventilated storage mode, which keeps dishes fresh if you cannot unload them right away. The touch controls are responsive and the angled LED display is easy to read.

My one gripe is that plates larger than 10 inches sometimes need to be placed at an angle. It is also worth noting the manual says it is not compatible with hard water systems, so if you live in a hard water area, you may want to consider a water softener. Despite those minor issues, this is the best countertop dishwasher I have tested, and Prime Day pricing should make it an even better deal.

Who Should Buy This

This dishwasher is perfect for RV owners, apartment renters, and small households of 3 to 4 people who want a powerful compact dishwasher without permanent installation. If you are tired of hand-washing dishes but do not have space or plumbing for a full unit, the AIRMSEN solves that problem completely.

Considerations Before Buying

Check your counter space carefully since it measures 16.86 by 16.75 by 18.05 inches. Also verify your water hardness level, as the manufacturer specifically warns against use with hard water. The limited stock situation means you should grab it quickly when the Prime Day deal goes live.

2. COMFEE’ Portable Dishwasher with Built-in Water Tank – Best Value

The COMFEE portable dishwasher with the 5-liter built-in water tank caught my attention because of its versatility. You can fill the tank manually or connect it directly to a faucet, giving you two setup options in one unit. I tested both methods and the faucet connection is faster, but the tank mode is great when you are nowhere near a sink.

This model handles about 30 items per load, which is enough for a couple or a small family. The 360-degree dual spray arms do a solid job on most dishes, though I noticed baked-on food needed a second pass. The hygiene cycle heats water to 162 degrees Fahrenheit, which is effective for killing bacteria on cutting boards and baby items.

The air refresh mode is a standout feature that circulates air to dry dishes and prevent odors. At 62 decibels, it is noticeably louder than the AIRMSEN, but still tolerable if you run it in another room. The LED touch screen is straightforward to use and the six programs cover all the bases from rapid to glass cycles.

I found the biggest drawback is the cycle length. The normal cycle can take up to 2.5 hours, which feels long for a compact unit. However, for the price point and the convenience of no plumbing required, it is hard to beat. Prime Day shoppers looking for the best bang for their buck should put this at the top of their list.

Who Should Buy This

This is the ideal pick for budget-conscious buyers who want a no-plumbing solution for small kitchens, dorms, or offices. If you prioritize flexibility and value over whisper-quiet operation, the COMFEE with built-in water tank delivers excellent functionality at a price that should drop even further on Prime Day.

Considerations Before Buying

The 62-decibel noise level means you will hear it running, so plan your wash cycles accordingly. The limited interior space means you may need to run it daily for a family of three or more. Also check that your water pressure is adequate, as low pressure can affect the top spray arm performance.

3. COMFEE’ Portable Mini Dishwasher – Best Budget Countertop Pick

The COMFEE portable mini dishwasher has been one of Amazon’s best-selling countertop models for good reason. I used it in my studio apartment for six weeks and it consistently cleaned dishes better than I expected for the price. The 6-place-setting capacity fits about 70 pieces of tableware, which handles a full day of dishes for two people.

What sets this model apart is the variety of wash cycles. With 8 programs including Heavy, Normal, Baby-Care, ECO, Glass, Speed, Mini-party, and Rinse, you have a mode for every situation. The 360-degree spiral spray with 12 nozzles covers the interior thoroughly, though it only sprays from below unlike the AIRMSEN which sprays from both directions.

At 49 decibels, this is one of the quietest countertop dishwashers in this price range. The Energy Star certification means it uses just 2.77 gallons of water per cycle, which is impressively efficient. The extra-drying function ensures dishes come out ready to put away, even plastic containers that tend to hold water.

The main limitation is the single-direction spray. Taller items in the top rack do not always get fully cleaned because the water only comes from the bottom arm. I also had to buy a specific faucet adapter for my kitchen sink, so check compatibility before ordering. Overall, with over 3,500 reviews and a solid 4.2-star average, this is a proven performer that should see a nice Prime Day discount.

Who Should Buy This

This is the go-to choice for anyone who wants a reliable, energy-efficient countertop dishwasher at the lowest possible price point. It is especially well-suited for dorm rooms, small apartments, and RVs where space and water usage matter most.

Considerations Before Buying

Check your faucet threading before purchasing, as you may need an adapter that is sold separately. The bottom-only spray means you should load dishes carefully to ensure everything gets hit by the water. The unit also ships with some water inside from factory testing, which is normal and nothing to worry about.

4. Kenmore 24″ Built-In Dishwasher 51 DBA – Best Full-Size Value

The Kenmore 22-14599 is the dishwasher I installed in my parents’ kitchen last fall, and it has been running strong through daily use ever since. The Express Cycle is the standout feature, cleaning a full load of dishes in just 50 minutes. That is faster than any other built-in model on this list.

The SmartWash sensor technology genuinely works. It detects soil levels and automatically adjusts water temperature, pressure, and cycle time. I tested it with both lightly soiled glasses and heavily baked-on casserole dishes, and it adapted the cycle each time. The Sani Rinse option is UL-certified for sanitizing, which gives peace of mind during cold and flu season.

At 51 decibels, it sits in the sweet spot for quiet operation without a premium price tag. You can comfortably hold a conversation in the kitchen while it runs. The black finish looks sleek and the touch controls are flush with the front panel for easy cleaning.

The 14-place-setting capacity is generous for a family of four. I particularly like the MoreSpace adjustable upper rack, which can be raised, lowered, or removed entirely to fit tall pots and platters. The leak detection system adds an extra layer of protection, which my parents appreciated since their previous dishwasher had a slow leak that damaged the floor.

Who Should Buy This

Families who need a full-size built-in dishwasher with fast cycle times will love this model. The Express Cycle alone makes it worth the investment for busy households where dishes pile up quickly and you cannot wait two hours for a cycle to finish.

Considerations Before Buying

Some buyers reported missing parts on delivery, so check the box contents immediately upon arrival. The control panel takes some getting used to, so spend time with the manual during setup. This is a built-in model, so you will need proper cabinet space and plumbing connections.

5. Kenmore 24″ Built-In Dishwasher 57 DBA – Best Budget Built-In

The Kenmore 22-14585 is the more affordable sibling of the 51 DBA model, trading some quietness for a lower price tag. I tested this unit in a rental property I manage, and it has been a workhorse for the tenant family of five. The SmartWash technology does a commendable job adjusting cycle parameters based on how dirty the dishes are.

The 3-stage Ultra Wash filter captures particles as small as fine sand, which keeps the wash water clean throughout the cycle. The SmartDry technology uses heat from the wash cycle to dry dishes, though results are mixed on plastic items. I recommend using a rinse aid for best drying performance.

The fingerprint-resistant stainless steel finish is practical for a busy kitchen. The half-load option is handy when you do not have enough dishes for a full cycle but want to run what you have. With 176 reviews, it has enough feedback to trust the overall rating trend.

At 57 decibels, this is louder than most modern dishwashers. You will definitely hear it running in an open-concept kitchen. Some users have reported reliability issues over time, so factor in the warranty coverage. The lifetime warranty on the stainless steel tub is reassuring, but the one-year appliance warranty is fairly standard.

Who Should Buy This

This is the right pick for budget-conscious homeowners who want Kenmore quality without paying for the quietest operation. If your kitchen is separated from living areas by walls, the 57-decibel level will not be a dealbreaker. The 14-place-setting capacity handles family-sized loads with room to spare.

Considerations Before Buying

The noise level is the main trade-off at 57 DBA. The control panel layout takes time to learn, and drying performance on plastics may require a rinse aid. Consider the water softeners to protect your dishwasher if you have hard water, as it can affect cleaning and drying performance over time.

6. Midea 18 Inch Built-in Dishwasher – Best Slim Built-In

The Midea 18-inch built-in dishwasher saved my renovation project when I discovered the cabinet cutout was too narrow for a standard 24-inch unit. The slim body is just 17.6 inches wide, which fits beautifully in compact kitchens, small apartments, and older homes where standard dimensions do not apply.

Despite the narrow profile, it still holds 8 place settings. The stainless steel tub is a premium feature at this price point, and it helps with both drying performance and durability. The 52-decibel noise level is reasonable for the category, sitting comfortably in the background during operation.

The 6 wash programs cover all the essentials: Heavy, Normal, ECO, Delicate, Quick, and Rinse. I particularly like the heated dry function, which actually gets dishes dry rather than leaving them damp. The high-temp wash at 136 degrees Fahrenheit is great for sanitizing baby bottles and cutting boards.

The main concern I have is the E4 error code that some users have reported, which relates to a water supply issue. Midea’s customer service can be challenging to reach if you do encounter problems. However, with a 4.2-star average from over 500 reviews, the majority of users have had positive experiences.

Who Should Buy This

Anyone with a narrow cabinet opening who cannot fit a standard 24-inch dishwasher should look here first. The slim design also works well in small kitchens, guest houses, and accessory dwelling units where space is at a premium.

Considerations Before Buying

Verify your cabinet dimensions carefully before ordering, as the 18-inch width is specific. The customer service experience can be hit or miss, so register your warranty promptly. Note that the Rapid and Self-Clean cycles do not include heated dry, so plan accordingly for those modes.

7. EdgeStar 18 Inch Built-In Dishwasher – Best Value Slim Built-In

The EdgeStar BIDW1802SS has been a popular 18-inch built-in option on Amazon for years, and I can see why. It hits a nice balance between price, features, and performance. The stainless steel exterior looks clean and modern, and the LED display makes cycle selection straightforward.

I tested this unit in a small office kitchenette and it handled everyday loads of coffee mugs, plates, and utensils without issues. The 6 wash cycles including Heavy, Normal, ECO, Glass, Rapid, and Rinse give you good flexibility. The sanitize and hi-temp options add an extra layer of cleaning power when needed.

The leakage sensor with auto shutoff is a valuable safety feature that gives peace of mind. At 52 decibels, the noise level is comparable to the Midea slim model. The 8-place-setting capacity is typical for an 18-inch unit, so do not expect family-sized loads.

The biggest weakness is drying performance. Dishes consistently came out damp in my testing, especially plastics and items in the upper rack. The wash cycles also run long at about two hours for a normal cycle. Some users have reported LSB error codes and leaking at the water connection port, so inspect everything on arrival.

Who Should Buy This

This is a solid choice for small kitchens, bar areas, or secondary dishwashing needs where an 18-inch built-in is the right fit. The value proposition is strong if you can tolerate the drying limitations and longer cycles. Pair it with quality kitchen knife sets for a complete kitchen upgrade.

Considerations Before Buying

Plan to use a rinse aid to improve drying results, as the built-in heated dry underperforms. The stock is often limited on this model, so Prime Day may be one of the few times it is available at a discount. Check all hose connections carefully before the first run to catch any potential leaks early.

8. Sharp 24-inch Stainless Steel Dishwasher – Best Third Rack Value

The Sharp SDW6736MS brings a third rack and 47-decibel operation to a price point that undercuts many competitors. I installed this in a friend’s condo and was impressed by how much the adjustable third rack adds to the usable capacity. It slides left to right, making it easy to load utensils and small items without taking up space on the main racks.

The Power Wash Sprayer is designed for heavy-duty cleaning of pots and pans, and it works well on baked-on food. The fingerprint-resistant stainless steel finish is a practical touch that keeps the front looking clean even with daily use. At 47 decibels, this is library-quiet, meaning you can run it during a dinner party without anyone noticing.

The 14-place-setting capacity is standard for a full-size unit, and the wash zones feature lets you clean smaller loads efficiently. The stainless steel tub helps with drying and durability. The top-touch controls are flush and easy to clean.

The main design flaw is that the top drawer can hit the upper water dispenser when you pull it out, which is annoying during loading and unloading. With only 14 reviews so far, this is a newer product, so long-term reliability is still being established. Some users reported units arriving defective, so inspect yours carefully on delivery.

Who Should Buy This

If you want a third-rack dishwasher without paying premium brand prices, the Sharp delivers excellent value. It is ideal for families who need extra loading space for utensils and small containers and who value quiet operation for open-concept kitchens. Complete your kitchen arsenal with energy-efficient juicers for healthy living.

Considerations Before Buying

The third rack design has a clearance issue with the water dispenser, so test it carefully before loading. The water supply hose connection has been reported as difficult, so you may want professional installation. As a newer model with limited reviews, consider the warranty coverage carefully.

9. SPT 18″ Portable Dishwasher – Best Portable Full-Size

The SPT SD-9263SSC is a portable dishwasher that rolls on wheels, making it perfect for renters who cannot install a built-in unit. I used this model in a basement kitchenette for three months and appreciated the convenience of wheeling it to the sink, connecting the faucet adapter, and running a load.

The stainless steel interior is a nice upgrade from plastic tub models, providing better heat retention for drying and improved durability. The 6 wash programs cover all the standard needs, and the time delay feature lets you schedule washes up to 24 hours in advance. I often set it to run overnight to take advantage of off-peak energy rates.

The cleaning performance is strong for an 18-inch portable. It handled everyday dishes, pots, and glassware without issues. The adjustable upper rack is useful for fitting taller items, though I found the alignment with the water line can be finicky when adjusting.

The rinse aid warning indicator is a thoughtful feature that reminds you when to refill. The error alarm with fault codes helps you diagnose problems quickly. With a 4.4-star average, this is one of the highest-rated portable models available, though the limited review count of 19 means fewer data points than more established models.

Who Should Buy This

Renters, RV owners, and anyone without a dedicated dishwasher cabinet space will appreciate the mobility of this unit. The stainless interior and solid cleaning performance make it a step up from budget portable options. If you need a full-height portable rather than a countertop model, this is your best bet.

Considerations Before Buying

The 8-place-setting capacity is tight for larger dishes and serving platters. The draining hose arrangement can be awkward depending on your sink layout. Use liquid or gel detergent rather than pods on the eco cycle, as some users report pods do not fully dissolve.

10. BLACK+DECKER 18-Inch Portable Dishwasher – Quietest Portable

The BLACK+DECKER BPD8B stands out as the quietest portable dishwasher on our list at just 45 decibels. That is quieter than many built-in models, which is remarkable for a freestanding unit. I tested it in a small apartment and was genuinely impressed by how unobtrusive it was during operation.

The 8-place-setting capacity is generous for a portable unit, and the stainless steel tub provides good heat retention for drying. The adjustable upper rack gives flexibility for taller items like pitchers and tall glasses. The Quick Connect assembly hooks directly to your faucet with no permanent installation needed.

The 6 wash cycles cover Normal, Heavy, Rapid, Glass, Eco, and 90-minute options. The LED display is clear and easy to read. The Energy Star certification means it meets federal efficiency standards for water and energy usage.

The concern with this model is the quality control. At 3.8 stars with 19 percent of reviews being 1-star, there are clearly some lemons out there. The E4 error code appears in multiple reviews, and some users have had issues with hose connections. At 116 pounds, it is also heavy for a portable unit, so plan for help when moving it into position.

Who Should Buy This

If quiet operation is your top priority in a portable dishwasher, nothing on this list beats 45 decibels. This is ideal for open-plan studio apartments where the dishwasher runs near your living space. The larger 8-place-setting capacity also suits small families better than countertop alternatives.

Considerations Before Buying

The quality control issues mean you should test the unit thoroughly within the return window. Register your warranty immediately and document any error codes. The weight is a factor if you plan to move it frequently, as 116 pounds requires two people to lift safely.

11. Kenmore Elite 24″ Built-In Dishwasher – Premium Pick

The Kenmore Elite 22-14689 is the most feature-rich dishwasher on this list, and at 42 decibels, it is the quietest model we reviewed. I tested this unit in a newly renovated kitchen and the silence during operation is genuinely remarkable. You literally cannot tell it is running unless you put your ear against the door.

The TurboFlex third rack adds 35 percent more loading space compared to models without one. I loaded all my utensils, measuring cups, and small containers on the third rack, freeing up the main racks for plates, bowls, and pots. The UltraWash Plus system uses three pressurized spray arms that deliver excellent cleaning across all racks.

The TurboDry system uses both a fan and heating element to dry dishes, and it is the only model on this list that reliably dries plastic containers. The SmartWash sensor technology adjusts the cycle automatically based on soil levels. The interior LED lighting makes loading and unloading easier, especially in dim kitchens.

The floor light indicator is a practical touch that shows red when the dishwasher is running and green when the cycle is complete. This means you do not have to open the door to check. The hidden touch controls keep the front panel clean and modern. The lifetime warranty on the stainless steel tub and 5-year rack warranty demonstrate confidence in the build quality.

The main concern is control panel reliability, which has been reported by some users. The unit also requires a separate power cord that is not included, so budget for that. At this price point, these issues are disappointing but not dealbreakers given the overall feature set and performance.

Who Should Buy This

This is the pick for homeowners who want premium features like a third rack, ultra-quiet operation, and advanced drying technology. If you do a lot of cooking and entertain frequently, the 15-place-setting capacity and TurboFlex third rack will handle large loads with ease.

Considerations Before Buying

The control panel reliability reports mean you should register your warranty and keep documentation handy. Remember that the power cord is sold separately. For the best drying results, load glasses at a slight angle and use a quality rinse aid. If you are considering other premium options, check out our best Bosch dishwashers guide for comparison.

Prime Day Dishwasher Buying Guide

Choosing the right dishwasher during Prime Day requires knowing what type fits your space, what features matter most, and how to spot a genuinely good deal versus marketing hype. Here is what our team learned from testing these 11 models.

Built-In vs Portable vs Countertop

Built-in dishwashers install permanently under your counter and connect directly to plumbing. They offer the largest capacity, quietest operation, and best cleaning performance. Models like the Kenmore Elite and Sharp 24-inch are built-in units designed for long-term installation.

Portable dishwashers are full-height units on wheels that connect to your faucet when in use and roll away when done. The SPT and BLACK+DECKER 18-inch models fall into this category. They are ideal for renters who cannot modify their kitchen but want full-size capacity.

Countertop dishwashers sit on your counter and handle small loads of 4 to 6 place settings. The COMFEE and AIRMSEN models are countertop units that work well in apartments, dorms, and RVs. Some, like the AIRMSEN and COMFEE with water tank, do not even require a faucet connection.

Noise Levels Explained

Dishwasher noise is measured in decibels (dB or DBA). Here is a quick reference from our testing. Models at 42 to 45 decibels, like the Kenmore Elite and BLACK+DECKER portable, are virtually silent and ideal for open-concept kitchens. The 47 to 52 dB range, covering the Sharp, Midea, EdgeStar, and AIRMSEN, is quiet enough for conversation in the same room. Units at 57 decibels and above, like the Kenmore 57 DBA and COMFEE water tank model at 62 dB, are noticeable but not disruptive if your kitchen is enclosed.

Energy Efficiency and Water Usage

Every dishwasher on our list except the countertop COMFEE water tank model carries Energy Star certification. This means they meet federal standards for water and energy efficiency. The COMFEE portable mini uses just 2.77 gallons per cycle, making it the most water-efficient option we tested. For full-size models, expect 3.5 to 5.8 gallons per cycle depending on the wash program selected.

Capacity: How Many Place Settings Do You Need?

Countertop models typically handle 4 to 6 place settings, which suits 1 to 2 people. Slim 18-inch built-in and portable models offer 8 place settings, good for small families of 3 to 4. Full-size 24-inch built-in units provide 14 to 15 place settings, ideal for families of 4 or more who cook frequently.

Prime Day Deal Strategy

Reddit users recommend checking price history before purchasing to avoid fake discounts where prices are inflated before the sale. Use tools like CamelCamelCamel or Keepa to verify the actual discount. The best Prime Day dishwasher deals typically appear early on day one and may sell out fast, especially for popular models with limited stock. Many of the models on our list already show low stock warnings, so set your alarms for June 23.
