Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and particularly relates to a rotary high-pressure cleaning device. Background Art

[0002] A high-pressure washer drives a high-pressure plunger pump to work through a power device, so as to generate high-pressure water or high-pressure cleaning liquid to wash an object, peel off and wash away dirt, and achieve the purpose of cleaning the surface of the object. Due to its advantages such as simple working principle, convenient operation, flexible and reliable use, it is widely used in various industries.
