US 2022/0016654 A1 · High-Pressure Cleaning Device

Abstract

A high-pressure cleaning device has a conveying pump and a conveying conduit with a spray opening. The conveying conduit conveys cleaning liquid, conveyed by the conveying pump, in a conveying direction from the conveying pump to the spray opening of the conveying conduit. A switch element is provided that has at least a first switched state and a second switched state. An actuator is provided that adjusts the switch element between the first switched state and the second switched state. The high-pressure cleaning device is provided such that the actuator adjusts the switch element between the first switched state and the second switched state by an adjusting force effected by the cleaning liquid on the actuator.
