Tired of doing dishes by hand, but can’t sacrifice cabinet space? Not to worry, you have alternatives! Aside from appliances with wheels, certain dishwashers intended to go under your counter can also be situated somewhere in your kitchen and hooked up without dedicated installation. When you’re done, you can roll it away until you need it again. But what do you need to know before you purchase yours, and how can you spot the option that suits you better? This and more, is what we cover further down. These are our reviews of the best portable dishwasher.

Special requirement: Water Supply

While a built-in dishwasher is hooked directly to the water supply, a more mobile appliance will take up your sink in order to receive water and drain it. The latter is fairly easy, all you need to do is use the sink’s own drain. For water intake, however, it gets tricky: your faucet spout has to be threaded (like this one), otherwise the hose cannot latch on. If yours has a sprayer, you might be able to remove it, but it is best to check with the manufacturer first so you don’t risk permanent damage. There’s a lot to consider when looking for the best portable dishwasher.

Same Mission, Different Perks

So many dishwashers out there, how to know which is the right one? There are several defining features that may make a difference depending on your taste, budget, space and average use. Below we go over them, one by one to find the best portable dishwasher.

Sound Level

When you tuck your dishwasher under your counter, the surrounding cabinets help reduce the noise generated as the appliance goes about its work. When it is in the open however, you don’t get this benefit. The more silently your appliance runs, the better. Every dishwasher we list here will include mention of its sound levels in decibels (dB)


There are three categories: full size, (about 85cm x 60cm x 60cm), able to fit over 100 items between cutlery, pots and pans; slimline (to the tune of 85cm x 45cm x 60cm), with average capacity just shy of 100 items; and compact, small enough to safely rest on top of your counter, and with just enough space for 60 items or so. The options we are covering here will be either full or slimline.

Choosing optimal size may be tricky: it will depend on the capacity you need, and on how much space you are willing to sacrifice both when using and putting away your dishwasher.


Similar to how a microwave may have preset settings for, say, thawing meat or cooking popcorn, dishwashers can come with programs for certain sorts of loads, such as half load, glass only, heavy soil and so on. 3 programs is fairly standard for most units, although some options will feature more. Certain choices will even have sensors to adapt the cycle on the go depending on the level of soil present in the load.

Start delay

Sometimes you may want to run the dishwasher at a later time, such as while you’re at work or sleeping. If this is your case, you may want to focus on options that let you set the start of the cycle for later.

Drying method

Your dishes will be dried in two possible ways. If they use hot air, they will be consuming extra electricity since they have to channel power through a heating element. A more economic but possibly less effective way is using the residual heat from the washing cycle to dry the load.

Adjustable racks and baskets

Some times you will be washing a full dinnerware set after a party. On occasion, you may be looking to clean up after several batches of cookies. Since your situations (and item size) will vary, being able to readjust position of your racks and baskets should prove quite handy.

Anti-flood protection

Certain dishwashers will feature a sensor at the end of the inlet pipe that will detect changes in water pressure, triggering a safety valve that shuts off the flow of water. This way, your machine will not get overfilled.

Washing potency

The more wash levels the better, and how powerful the arms are is also relevant, as it will directly affect how clean your dishes come out.

Food grinder

A feature that is not universal but may provide some peace of mind. Similar to a garbage disposal, a blade rotates at extremely high speed to pulverize food particles and keep them from clogging the arms.

Energy efficiency

Many dishwashers come with Energy Star certification, which is a trusty way to verify your chosen dishwasher won’t be running your utility bill too high.

Our Top Picks

Big, not so big, budget friendly: here are our chosen appliances, categorized.

The heavy wash cycle will add time to work on dishes with heavy soil, and the high temperature option helps with baby bottles, glassware and similar items.

If you would rather use dishes straight out of the machine, you can use the Heated Dry option; this comes at an additional energy consumption costs.

For the DIY-oriented: Turning a Built-in Into a Portable

If you do have the threaded faucet, another possibility opens up: a conventional, built-in type dishwasher that hooks up and works like a portable. It’s not exactly simple, but it is doable. Here’s what it will take:

  • Castor wheels, or a furniture dolly, so the unit can be moved around.
  • Heavy-duty hose, the type that can endure constant pressure and hot water, for attaching to the machine’s intake. The end that will hook onto the faucet should have a Y-adapter attached, to relieve pressure after the machine is done washing the dishes.
  • Another length of hose for the drain. This one doesn’t have to be as strong as the one for the intake, as it won’t be under pressure so often; but, getting a sturdy one doesn’t hurt either. Garden variety hose should do the trick.
  • Faucet adapter, so the hose can latch onto your threaded spout.
  • A power cord, to weave the washer’s electric wiring into. It will often includes wire nuts, but you can get them separately if needed. Unless the manufacturer says otherwise, the scheme is simple: green goes with green, white attaches to white, and black matches with black.
  • Hose clamps, to secure a length of hose to another. Teflon tape is also recommended, to help prevent leaks.

Useful pointers

  • When you’re looking for the best portable dishwasher, the center of gravity will be a factor. Whereas a built-in is usually held by the counter where it is installed, a free roaming appliance can tip over when you open the door and slide the racks out.
  • Hose lengths should be kept to a reasonably minimum length. The shorter the hose, the easier it is for the pump to work.
  • Drain hose should be held high, about mid height of the machine, so the water won’t build up within or stream back.
  • The area where wires are joined, should be kept off the floor and protected so any leaks will not affect it.

 A Few Good Convertibles

Below you will find a selection of appliances that, while intended for undercounter installation, should be suitable for converting into portables.
