Abstract
The cleaning device comprises a squeegee (1) formed of a blade of elastic material, inside which are formed suction ducts (5) which open in at least one face of the blade through orifices (7) aligned in parallel with the lowermost edge (8) of the squeegee, close to that edge. The suction ducts (5) are connected with flexible tubes (10) passing through a roller-type pump (11) towards a collector tank (15) in which the dirtied cleaning liquid to be eliminated is collected. This device may be used for removing a cleaning liquid having previously been spread over a surface which is to be cleaned.
