  • Patent number: 5666685
    Abstract: The invention relates to a hand-held unit (200) for cleaning smooth surfaces and for squeegeeing liquid. The hand-held unit is made up of a cleaning unit (230) with a handle (234) and a wiper plate (238) as well as of a squeegeeing unit (232) with a rear stop (252) of the squeegeeing unit (232). A handle (236) of the squeegeeing unit (232) can be pushed telescopically into a tubular handle (234) of the cleaning unit (230) until a stop edge (252) of the squeegeeing unit strikes against a front stop edge (242) of the wiper plate (238). The two units (230, 232) can be held, by at least one latching and/or frictionally locking connection, in the position in which they are pushed one inside the other to provide the hand-held unit (200), and can be released from one another by hand. Consequently, for the connection of the two units (230, 232), there is no need for any additional shaping or parts which obstruct the combined or separate handling of the units.
