TRAVELLING FLOOR CLEANER

Japanese Patent JPH0191824

A

PURPOSE: To make uniform the state of cleaning on the surface of a floor by alternately opening/closing solenoid valves successively for every rotary pad so that the quantity of detergent to be diffused per unit area can become a set value from the traveling speed information of a traveling body. CONSTITUTION: When the cleaning device starts cleaning and the traveling speed of a traveling body from a speed detector 42 installed on the driving wheels of the traveling body is inputted to a solenoid valve opening/closing time operating device 43, this device 43 operates and output the opening time of left and right solenoid valves 31 and 32 corresponding to the traveling speed so that the quantity to be dispersed per unit area can be equal with the set value of quantity to be dispersed set to a dispersing quantity setter 41. A solenoid valve driving device 44 to be operated according to the output of this solenoid valve opening/closing time arithmetic device 43 repeatedly and alternately opens/closes the left and right solenoid valves 31 and 32 and detergent liquid 21 is supplied to the central parts of left and right rotary pads 31 and 32. The rotary pads 31 and 32 uniformly diffuse this detergent liquid onto the surface of floor while rotating.
