No, a portable dishwasher cannot be directly hooked up to a bucket or another water source instead of a sink. Portable dishwashers are designed to be connected to a kitchen faucet, typically using an adapter that screws onto the faucet. The faucet provides both the water supply and the drainage for the dishwasher.
The reason for this design is that portable dishwashers rely on the water pressure from the faucet to operate effectively. They require a steady and consistent water flow to properly clean and rinse the dishes. Additionally, the drain hose of the dishwasher needs to be connected to a sink or a drain to allow the wastewater to be expelled.
If you do not have access to a sink, it may be challenging to use a portable dishwasher. However, you may explore alternative options such as installing a temporary sink or using a countertop dishwasher that has a built-in water reservoir and does not require a direct connection to a faucet.
