Abstract
'Suction attachment, spray member suitable for use in such a suction attachment, and vacuum cleaner provided with such a suction attachment.' A suction attachment (1) for a vacuum cleaner (119) is provided, which suction attachment (1) has an underpressure chamber (7) with a suction opening (23, 25) and a discharge channel (9) for connection to a suction motor assembly (121) of the vacuum cleaner (119). In the underpressure chamber (7) there is an inner chamber (11) which comprises a spray member (73) for distributing a cleaning liquid over a surface to be cleaned. The spray member (73) comprises a distributor plate (79) which is positioned near an upper side (19) of the inner chamber (11) in a central position relative to an orifice (75) of the inner chamber (11). The distributor plate (79) extends parallel to the side walls (51, 53) of the inner chamber (11) and can be sprayed with the cleaning liquid from a spray nozzle (99). The use of the distributor plate (79) creates in the inner chamber (11) a plane, diverging liquid jet, so that the cleaning liquid is uniformly distributed over a major portion of the orifice (75) of the inner chamber (11) and the surface to be cleaned. The vacuum cleaner (119) is fitted with a suction motor assembly (121) which can be connected to the discharge channel (9) of the underpressure chamber (7) of the suction attachment (1) via a liquid separator (131), and with a cleaning liquid reservoir (141) which can be connected via a liquid pump (143) to the feed channel (77) of the inner chamber (11) of the suction attachment (1).
