Abstract (en)
[origin: EP0140234A2] 1. Suction cleaner, comprising a motor fan unit which is located in a suction cleaner housing and generates a suction air blast which supplies dusty air flowing into the suction cleaner from a cleaning tool via a suction pipe to a dust filtering or dust collecting means such as a paper filter bag or the like, which is located in a dust chamber of the housing, which dust chamber can be locked by an inside cover which serves as a pan for depositing cleaning tools therein and which is covered by a lockable cover which is hinged to the housing and has a grip, characterised in that without a locking mechanism and a grip for the inside cover (11) being required, the inside cover (11) and the outside cover (16) are joined to each other by means of at least one holding device (22) which exerts a given tractive power on one of the covers, said tractive power being smaller than the underpressure which acts inside the dust chamber (10) with the motor fan unit (7) running and thus acts also on the inside cover (11).
