The concept behind countertop dishwashers was always a good one. But for years, even the top-dollar models failed to deliver anything close to the spic-and-span results of a traditional unit. But that was then. Now, options like the ENERGY STAR-rated Danby DDW1801MWP finally equal their full-size peers in performance—even while providing the extra flexibility and convenience of a portable design. Setup is simply a matter of plugging in the dishwasher and hooking its hose up to the kitchen faucet. Perhaps the most amazing part: Despite being compact enough to rest comfortably on a counter, the Danby appliance boasts enough capacity and cleaning power to handle up to six place settings in each cycle. Available at Amazon; $229.99.
