Abstract
In a portable cleaning apparatus, at least two rotatable cleaning members are mounted within a casing and contra-rotationally driven by an electrical motor and step-down gearing arranged between the motor and the cleaning members with a releasable clutch connecting the driving motor to the cleaning members. A cover is mounted over the rotatable cleaning members and the electrical motor and the casing includes a vent channel communicating with the cover. Suction from the at least two cleaning members to a dust collector, mounted at the end of the vent channel formed as a handhold, is provided by a blower driven by the electrical motor. The axes of the driving motor and the at least two cleaning members are parallel with one another and a blower rotor connected to a shaft of the driving motor is arranged behind an opening out of the cover into the casing as viewed from the direction of air flow.
