Individuals generally purchase portable dishwashers if they do not have the space to install a dishwasher, or if they are renting a home or apartment that does not have a dishwasher. Some portable dishwashers offer an optional built-in installation kit if permanent installation is eventually desired.
Portable dishwashers are equipped with four wheels on the bottom to allow for easy moving. To use a portable dishwasher, it must be hooked up to a kitchen or laundry sink with a hot water supply. A faucet adapter is usually required. Because hot water is returned back to the sink to drain, using caution around the sink is recommended while the dishwasher is running.
