In a floor surface cleaning device, an electrolyzer (10) for electrolyzing cleaning water into alkaline water and acid water is installed in a device body (1) that has wheels (4a, 4b) and can travel on a floor surface (9). The cleaning device has an ejection nozzle mechanism (23) which selectively sucks the alkaline water or the acid water electrolyzed by the electrolyzer (10), pressurizes the sucked water by a booster pump (20), and ejects the water pressurized by the booster pump (20) onto the floor surface (9). The cleaning device also has a suction nozzle (49) fitted to the device body (1) on the rear side of the ejection nozzle mechanism (23) and opened toward the floor surface (9). The cleaning water ejected onto the floor surface (9) is sucked together with contaminants by a sucking mechanism (43). The sucked cleaning water is contained together with the contaminants in a containing tank (44) mounted on the device body (1). |
