Abstract: The specification discloses a wheeled commercial carpet vacuum cleaner having wide area coverage, an integral one piece molded polymer housing enclosing a debris hopper with a plurality of inverted filter tubes therabove and enclosed by a filter housing in engagement with the hopper. The open bottom filter tubes are normally retained up in extended condition by springs therein which are compressible under the action of a manually operable depressor plate, plunger and linkage via an external handle, to act as a shaker distorting the tubes to dislodge dirt from the filter inner walls and allow it to fall into the debris hopper. One or more vacuum motors and suction fans are operable connected to the filter housing. A vacuum conduit extends between the area adjacnet a carpet-engaging power brush and the debris hopper. The suction fans pull dirt-laden air from the brush area through the tube and into the hopper, and from there up through the filter tubes.
