(54) A dustproof vacuum cleaner


(57) In a vacuum cleaner, the air is not expelled into the environment but is recirculated into the suction region (1,4); this prevents the dispersal of any traces of dust into the environment. The vacuum cleaner has advantages with regard to power, energy, and noise and enables the air to be treated with physical/chemical aids. A "robot" structure benefits particularly from this innovation.
