<p>The implement for cleaning surfaces, such as walls and ceilings, consists of a rotary roller (6) made of flexible material and with an axis parallel to the surface being cleaned. Resting against the cleaning roller is a wringer roller (10) whose axis is parallel to it, and which is made of harder material than the cleaning roller. The cleaning roller is supplied with cleaning fluid by a pipe (8) also parallel to it. A trough (20) collects the spare cleaning fluid. Two parallel rollers (5) are mounted near the two edges of a frame (1) which is fixed by a bracket (3) to the end of a long handle. A flexible scraper (18) is positioned behind the cleaning roller.</p> |
