015368000 | Adjustable with respect to nozzle | 6 |
20080222839 | Suction Nozzle and Vacuum Cleaner Provided with Such a Suction Nozzle - The invention relates to a suction nozzle ( | 09-18-2008 |
20090100636 | Vacuum Cleaner Nozzle with Disposable Cover Sheet - A vacuum cleaner base includes a source of suction and front wheels and rear wheels for wheeling the base across a floor. A nozzle assembly is attached to and supported by the base. The nozzle assembly includes a suction inlet and a sheet-pressing surface that are located in front of the front wheels. A disposable sheet is configured to be removably attached to the nozzle assembly such that, as the base is wheeled across the floor, the sheet-pressing surface presses the sheet against the floor to dislodge dirt from the floor, and the suction draws the dirt from the floor through the suction inlet. | 04-23-2009 |
20090320233 | FLOOR CARE APPLIANCE WITH A PLURALITY OF CLEANING MODES - A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance is comprised of a base portion having a suction nozzle and a brush block having a plurality of vertical axis rotary agitators for cleaning bare floors. The rotary agitators are driven by an independent motor for agitating the floor surface. With the addition of an accessory hose and tools, the cleaning utility can be expanded to areas wherein the suction nozzle cannot normally reach such as behind the toilet, shower walls, and the grout between tile. While used in the capacity for cleaning bare floors, the floor care appliance can be moved between three modes by a rotating a member located on the upper housing. The first mode is dry mode, the second mode is wet scrub mode and the third mode is wet pickup mode. The accessory tools are stored in an accessory caddy that is placed freestanding over the suction nozzle and in front of the housing. | 12-31-2009 |
20100192323 | SURFACE TREATING HEAD ASSEMBLY - A surface treating head assembly for an appliance such as a vacuum cleaner includes a head and a drivable agitator in the form of a brush bar, rotatably housed in the head. A cam arrangement is rotatably driven in the head. The cam arrangement includes a pair of cams, each having a plurality of cam faces, each cam face corresponding to respective predetermined vertical positions of the brush bar. Thus, the height of the brush bar is selectively controllable between the predetermined positions, such that the depth of penetration of the bristles of the brush bar may be optimized for different types of carpet. | 08-05-2010 |
20130145576 | Vacuum Assisted Fur Removal Tool - Described is a self-cleaning vacuum cleaner accessory apparatus, method, and system including a tubular element, a nozzle, and a nozzle housing that can include at least one nozzle housing notch. The apparatus can further include a bristle plate coupled to the nozzle housing. The bristle plate can include at least one bristle and at least one tabular release element to control the movement of at least one bristle plate tab. The at least one bristle plate tab can be coupled to, or decoupled from, the at least one nozzle housing notch to either permit or prohibit the bristle plate's movement with respect to the nozzle housing. The bristle plate can further include a pivot for rotating the bristle plate to invert the at least one bristle's orientation. Once inverted, airflow from a vacuum can remove debris from the bristles before returning the bristle plate to its original orientation. | 06-13-2013 |
015371000 | Floating or resiliently biased contact with work surface | 1 |
015372000 | Rotary work contactor | 1 |
20140130294 | AUTONOMOUS COVERAGE VACUUM CLEANER HAVING EDGE CLEANING HEAD EASY TO INSTALL AND UNINSTALL - An autonomous coverage vacuum cleaner includes a transmission element driven to rotate and disposed at the bottom of a body, and an edge cleaning head. The transmission element has a lower surface, a positioning recess denting upward from the lower surface and having a non-circular inner profile, and a fixing hole disposed in the positioning recess. The edge cleaning head includes a body, at least a brush extending from the body, a positioning block disposed on the body, and resilient elements extending upward from the positioning block. An outer profile of the positioning block corresponds in shape to the inner profile of the positioning recess. Under an applied force, the resilient elements deform resiliently, get closer to each other, and engage with the fixing holes. The positioning block engages with the positioning recess of the transmission element, such that the transmission elements drive the edge cleaning head to rotate. | 05-15-2014 |
