If you live in a condo or apartment that doesn't have a dishwasher, or need a dishwasher for an office kitchen, a portable dishwasher might be the best option. Portable dishwashers offer similar cycle features and interior designs to built-in dishwashers, but can be moved around on wheels and hook up to your kitchen faucet and drain into the sink. In an older home or other areas with limited cabinet space, a portable dishwasher can provide the cleaning power of a built-in dishwasher without the hassle of installing it into the cabinetry and installing the necessary plumbing.
