A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.
