Abstract:
A cleaning device (100), comprising a machine body (10), a cleaning mechanism (20) and a lifting mechanism (30). The cleaning mechanism (20) comprises a rolling brush assembly (22), the rolling brush assembly (22) is disposed at the bottom of the machine body (10) and is movably fitted with the machine body (10), the lifting mechanism (30) is disposed on the machine body (10), and the lifting mechanism (30) can drive the rolling brush assembly (22) to be separated from a surface to be cleaned. The lifting mechanism (30) is arranged on the machine body (10), and the rolling brush assembly (22) is arranged at the bottom of the machine body (10) and can move relative to the machine body (10). When a cleaning operation is performed on the surface to be cleaned by means of the cleaning device (100), the rolling brush assembly (22) removes solid waste on the surface to be cleaned; and when there is a water stain or an oil stain of fluid waste on the surface to be cleaned, the lifting mechanism (30) drives the rolling brush assembly (22) to separate the rolling brush assembly (22) from the surface to be cleaned to prevent the fluid waste from coming into contact with the rolling brush assembly (22), so as to prevent the cleaning effect being affected due to the adhesion of the fluid waste to the rolling brush assembly (22).
