(57) [Summary] [Purpose] The optimum solution can always be applied, (EN) Provided is a floor surface cleaning device which does not stain the surface after work with wheels. [Structure] The forward measurement wheel 3 is provided in front of the working unit 7 for performing work. The apparatus has a and 3b and rearward measurement wheels 5a and 5b behind the working unit 7. The measuring wheels 3a, 3b, 5a, 5b measure the traveling speed of the device, and the liquid agent is dropped from the liquid agent dropping nozzles 11a to 11d at a speed based on the measured traveling speed, Nonwoven fabric rotating plate 9a at a speed based on the measured traveling speed ~ 9d rotates and the liquid agent is applied. When the device is moving forward, the forward measuring wheels 3a, 3b come into contact with the floor, and the backward measuring wheels 5a, 5b b is controlled to move away from the floor, and the backward measurement wheels 5a and 5b contact the floor when the vehicle is moving backward, and the forward measurement wheels 3a and 3b are controlled to move away from the floor. As a result, the measuring wheel does not stain the floor surface after the work. |
