Portable dishwashers are typically either mounted on wheels or designed to sit on a countertop, and they’re a great option if you don’t have space for a built-in appliance. Before you add this convenient machine to your cart, it’s important to measure your space. “If you look for countertop dishwashers, check the size of both the dishwasher and your countertops,” says Alex Varela, general manager of Dallas Maids. “Although they are created with a size that’s meant to fit in regular-sized countertops, it’s always best to check dimensions first to ensure they will fit perfectly.” We researched the best portable dishwashers available, evaluating each on performance, ease of use, and special features.

Our top pick, the GE 24-inch Portable Dishwasher, offers the convenience and capacity of a full-size dishwasher, yet it’s mounted on caster wheels and hooks up to a faucet for easy operation.

Here, the best portable dishwashers for clean dishes in any space, large or small.

Final Verdict

If you’re looking for a full-size portable dishwasher, there’s no better option than the GE 24-inch Portable Dishwasher. It boasts a spacious interior that can hold up to 12 place settings, as well as hidden controls and a hard food disposer—all for a reasonable price. For something a bit cheaper, consider the BLACK+DECKER BCD6W Compact Countertop Dishwasher. It has a quick-connect assembly that hooks up to your faucet in a flash, and it even has a heated dry setting to remove lingering water from your clean dishes. 


There are two types of portable dishwashers: countertop and freestanding. As its name suggests, a countertop model sits on your kitchen counter and hooks up to your sink. It can fit six place settings at a time and usually has a pull-out rack or drawer design. A freestanding model is more spacious and has the look and feel of a full-sized, built-in dishwasher. This type of dishwasher usually has caster wheels to change its location or is convertible—meaning you can remove the caster wheels to give it a more permanent home. A freestanding model is suitable for larger families and households since it can fit up to 12 place settings at a time.

Noise Level

The amount of noise a dishwasher produces during a cycle is measured in decibels (dBA). A standard dishwasher can be as quiet as 40 dBA or as loud as 62 dBA, which will require you to go into another room if you’re trying to have a conversation. If you live in a smaller space, you’ll want to find a model with a low decibel rating that won’t disturb your household. Many units on the market fall in the 52 to 54 dBA range, which is quiet enough for a conversation.

Extra Settings

A portable dishwasher doesn’t typically have as many specialty settings as a full-sized, built-in dishwasher. If you opt for a countertop model, your cycle options are usually normal, intensive, glass, and soak. However, some portable dishwashers come with extra features like a delayed start, which will push back your cycle for up to 24 hours, and eco-mode, which will ensure your appliance doesn’t use more resources than it needs to. These selections may cost more upfront but save you time and money down the road.

Convertible Design

If a portable dishwasher is convertible, that means you can install it like a built-in model at any time. A convertible dishwasher has removable caster wheels that can be used to roll the appliance into a convenient spot of your home or taken off so you can place the appliance in one place. This versatile design is most helpful for households that want their machine to be long-lasting and suitable for many different living situations.

Stainless Steel Tub

A stainless steel tub is more durable than a plastic dishwasher tub. If you opt for a stainless steel tub, the interior will look stylish, and it won’t show wear and tear as quickly as a plastic version since it’s much less likely to develop stains from food debris left on your dishes. Also, since metal is more conducive to heat, this type of tub can help effectively dry your dishes, especially when paired with a fan or a steam function.

Hard Food Disposer

Hard food disposers help eliminate food debris from your dirty dishes. After a water jet releases the debris from your cups and plates, it falls into this disposer and is filtered out of the water that will continue to circulate and clean your dishes. This feature is key to keeping the interior of your portable dishwasher free of odors and bacteria. It’s also handy for households who are in a rush or don’t want to take the extra step of rinsing their dishes before loading them.


  • A portable dishwasher works as well as a full-sized dishwasher but may have capacity limitations. You may only be able to wash six or eight place settings, as opposed to 12. In addition, you likely won’t be able to wash bulky items like strainers and cookware. However, most portable models are still very powerful and have a collection of strong water jets. You’ll still be treated to features like an adjustable rack or hard food disposer that’ll leave your dishes very clean.

    To get the best experience out of yours, be sure to not overload the machine and clean it about once a month.

  • It’s not recommended that you run a portable dishwasher overnight. While this appliance doesn’t need constant supervision, it requires a temporary hook-up to your sink. Once your cycle is done, you’ll want to follow your user manual’s instructions for unhooking the dishwasher and storing it. You’ll also want to make sure there weren’t any leaks. This process may be inconvenient but will ultimately keep your household safer and mess-free.

  • A portable dishwasher drains into your sink and down the disposer with the help of a hose, a faucet adaptor, and an essential connection piece called a unicouple. The unicouple ensures the drain is not overpowered and that the appliance has the water it needs to operate. When water needs to be drained from the appliance, it’ll travel through the hose and into your sink’s disposer.

    If your model isn’t draining, you may have a clog. If this happens, make sure the sink’s disposer and the hose are clear and follow any additional troubleshooting tips in your user manual.

  • Yes. Portable dishwashers can be connected permanently to a water source and drain. Depending on if the dishwasher is top or front loading and where the controls are located, you might be able to permanently install it under the counter. Be sure to purchase a dishwasher installation kit for your unit’s make and model in order to change the water and drain fittings for permanent use.

  • If you connect a portable dishwasher to a pull-down faucet, there is a risk of pressure fluctuations occurring during operation that may cause the hose to rupture. But some portable dishwashers come with an adapter that allows you to hook up the unit to a pull-down faucet. This will require you to remove the faucet’s aerator, install the adaptor, and then connect the hose.
