s3, when the bristle brush (20) cleans the surface of the ladder, the screw rod (10) is driven to rotate by the motor I (29), the screw rod (10) can drive the support plate II (15) and the support plate I (14) to move forwards by the cooperation with the thread sleeve (11), the slide rod (12) and the slide sleeve (13), the disc (19) and the bristle brush (20) can be driven to move forwards by the support plate I (14), and when the disc (19) and the bristle brush (20) move to the foremost side of the movable range, the motor I (29) drives the screw rod (10) to rotate reversely by the control switch (28), so that the disc (19) and the bristle brush (20) move backwards, and the disc (19) and the bristle brush (20) move forwards and backwards in a reciprocating manner, so that the surface of the ladder can be cleaned comprehensively;

s4, after one step is cleaned, the device is pulled downwards by a pushing handle (27), the universal wheel (4) contacts with the upper surface of the next step firstly, meanwhile, the vibration of the whole device during falling can be reduced by the matching of a telescopic rod (2) and a spring (3), then the position of the device is adjusted, the hard brushes (20) arranged on two disks (19) are respectively attached to the upper surface and the vertical surface of the step, then the steps can be cleaned by repeated operation according to the steps, the brush (25) contacts with the upper surface of the cleaned step, so that impurities cleaned from the upper surface of the step can be swept into a garbage hopper (16) by the brush (25), and after one step is cleaned, the device is pulled downwards by the pushing handle (27) to step into the next step, therefore, the ladder of the group can be cleaned step by step from top to bottom.
