Abstract: A high-pressure cleaning system with a high-pressure cleaning appliance including a pump, a motor, a pump inlet and a pump outlet, and a control device, and with at least one discharge unit adapted to be brought into fluid connection with the pump outlet for discharging pressurized cleaning liquid is disclosed. In order to further develop the high-pressure cleaning system in such a way that as good a cleaning result as possible is more easily achievable, the high-pressure cleaning system includes a detection unit by which the type of discharge unit presently in fluid connection with the pump outlet is detectable and which is connected in a signal-transmitting manner to the control device, at least one conveying parameter of the high-pressure cleaning appliance being automatically adaptable by the control device to the detected type of discharge unit. A discharge unit for such a high-pressure cleaning system is also disclosed.

Abstract: A spray gun for a high-pressure cleaning appliance is provided, with a gun casing, in which is arranged a valve, which has a through duct which extends from a valve inlet to a valve outlet, and has a closure body which, in a closed position, bears in a fluid-tight manner against a valve seat and which is adapted to be moved, with the aid of a hand lever mechanically coupled to the closure body, into an open position spaced apart from the valve seat, and with an electric apparatus which has an electric display device and at least one battery. The electric apparatus has an electric casing which is sealed against sprayed water and forms a sub-unit adapted to be handled independently, wherein all of the current-carrying components of the spray gun are arranged in the electric casing and are separated galvanically from the remaining components of the spray gun.
