A built-in tank lets a dishwasher run with no faucet and no plumbing nearby: you pour in about 5 or 6 liters, press start and drain the used water into the sink. That suits RVs, dorms, offices and rentals where nothing can be attached to a faucet. Most also accept a faucet hose, so they work either way.
