Abstract (en)
[origin: US4419784A] A portable brush vacuum cleaner includes a casing enclosing an electric motor for a suction fan. The casing also encloses at least one roller cleaning brush driven by a speed reduction gear. A brush housing is connected to a dust collector provided above the roller brush. The brush housing is also connected with the suction side of the fan through a suction channel. In a divided space above the roller brush an additional suction chamber is provided which is partially formed by baffle elements. The additional suction chamber extends about the whole length of the brush or brushes and opens into the suction channel leading to the dust-collector.
