Danby DDW1801MWP
The best portable dishwasher
The Danby DDW1801MWP rolls up to your sink, hooks up to the faucet, runs like any old dishwasher, then wheels back into storage when you’re done.

The Danby DDW1801MWP is one of the cheapest portable dishwashers available, but don’t let its price fool you. It has many of the same features you might find in a medium-quality built-in dishwasher, including a stainless steel tub, quiet performance, folding tines, and Energy Star compliance. That said, if you can install a built-in dishwasher, we recommend exploring that option over the Danby.
