If you’re tired of hand-washing and -drying dishes, but you can’t install a built-in dishwasher in your home, a portable or countertop dishwasher could grant you an honorable discharge from dish duty.Portable dishwashers hook up to your faucet or other water line, and they can be wheeled around your kitchen (as well as into and out of it). Otherwise, they operate similarly to their permanently installed counterparts.Countertop dishwashers — which have their share of limitations — draw from a sink, a water line, or an onboard tank. And they typically take up about as much room as a dish rack would.I recommend the GE GPT series portable dishwashers, which come in space-saving 18-inch and standard 24-inch versions.If you have your heart set on a countertop dishwasher, the Loch Capsule is the one to try.
