Abstract

A vacuum cleaner including a vacuum source in the form of a fan arrangement (15) comprising a fan unit (22). The fan unit (22) is driven by a commutator motor (23) via a shaft (30). The commutator (24) is received in a separate chamber (31), which is sealed from the other parts of the electric motor. The chamber is connected to an inlet channel (36) and an outlet channel (37). Air flows through the chamber and takes up carbon particles from the commutator and delivers same to a dust bag.
