发明名称 Floor cleaning device
摘要 A matted fleece cleaning pad is supported on a number of spread-out tufts of bristles set in cavities of a holding plate, the bristles of each tuft being of different length and made of a synthetic plastic, preferably a polyamide. By this arrangement, the cleaning pad can be held springily, so that it can follow irregularities in the floor. The longer bristles are beaded at their ends by singeing, so that the cleaning pad does not fall off when the holding plate is lifted up from the floor.
