摘要： A battery-powered, upright vacuum sweeper comprises a base assembly and a handle pivotably attached thereto. The base assembly comprises a vacuum fan assembly fluidly communicating with an inlet for vacuuming dust and the debris particles from a surface into a removable reservoir. A rotating roller brush attached to the base assembly sweeps the particles into the inlet. A dust pad assembly comprises a disposable dust cloth extending over a portion of the base assembly in contact with the surface to be cleaned for removing dust particles which are not removed by vacuuming.

摘要： A multi-use vacuum cleaner has a central body which houses a motor, air impeller, battery and a dirt collection chamber. One end of the central body has a face inclined to the longitudinal axis of the central body with a rectangular inlet orifice into which the coupling nozzle of a floor and carpet pickup head can be frictionally inserted. The other end of the body has an integral, axially protruding extension providing a primary handle for manipulating the body as a hand held cushion and upholstery cleaner. The primary handle has means for detachably mounting an extension handle permitting the unit to be used as a standard upright vacuum cleaner or for vacuuming overhead and other areas which would be otherwise inaccessible.

摘要： A floor sweeper has a pair of brush rollers, each sweeping into its own dust pan. Each brush roller has different debris pickup characteristics, with one brush roller tending to be more efficient in picking up large debris and the other roller tending to be more efficient in picking up smaller debris. The illustrated embodiment discloses a front brush roller of the off-center tufted type which rotates continuously toward its respective pan during reciprocal sweeper translation, with a relatively high free-wheeling rotation in one direction of sweeper translation. The rear brush roller is of the wire twist type and also rotates continuously toward its pan during reciprocal sweeper translation, but with relatively low rolling rotation in one direction of sweeper movement.

摘要： A vacuum cleaner is provided with a suction nozzle and a cylindrical rotary brush. The brush includes a plurality of generally longitudinally extending rows of uniform bristle tufts. Alternate tufts in alternate rows are spaced at about twice the distance as the remaining more closely spaced tufts and prepare the carpet for sweeping by the latter.PRIOR ART OF INTERESTU.S. Pat. Nos. 1,044,488, Case, 11/19/12; 1,970,355, Bennet, 8/14/34; 2,281,798, Prince, 5/5/42; 2,459,007, Taylor, 1/11/49; 2,659,921, Osborn, 11/24/53; 3,716,889, Goldstein, 2/20/73; 3,815,170, Brooks et al, 6/11/74.BACKGROUND OF THE INVENTIONVacuum cleaners have long been considered one of the most effecient devices for removing debris from carpets and the like. Many modern cleaners, when of the upright type, often comprise a power head portion having a vacuum nozzle, a rotary brush in the nozzle for engaging the carpet, and a brush drive motor; as well as an upright handle or stick pivoted to the head and including a suction motor and a storage chamber for receiving the material removed from the carpet.The rotary brush has usually comprised a cylindrical core having rows of brush bristle tufts. In many prior constructions, the tufts were arranged longitudinally along the core surface in straight or spiral rows, with adjacent tufts being close together and equally spaced.Various attempts have been made over the years to improve the ability of the rotary brush to loosen debris on the surface and deep within the carpet so that the material may be readily sucked through the nozzle into the storage means. For example, in the above-mentioned Prince U.S. Pat. No. 2,281,798, a rigid beater bar is used in conjunction with the brush row. In Taylor U.S. Pat. No. 2,459,007, it is suggested to provide alternate rows of short stiff tufts and long flexible tufts. In Osborn U.S. Pat. No. 2,659,921, it is suggested to use three rows of brush bristle tufts, each of a different stiffness. In Goldstein U.S. Pat. No. 3,716,889 it is suggested to provide alternate "agitator elements" in each row, with alternate rigid and resilient elements.It is readily apparent that all of these "improved" brushes are subject to the disadvantage of increased cost of manufacture, as compared with the aforementioned rotary brush wherein all the rows comprise identical equally spaced tufts of the same length. It is expensive to provide multiple types of tufts or other agitator elements in the same brush and has required special tufting machinery and/or multiple passes through a single machine. Furthermore, rigid agitator elements or beater bars subject the carpet to undesirable wear.SUMMARY OF THE INVENTIONThe present invention solves the aforementioned problems, and is based on the very surprising discovery that complete removal of alternate tufts from alternate tuft rows in a brush wherein the tufts are otherwise all uniform provides a substantially increased cleaning efficiency in a vacuum cleaner of the type indicated. Such a result was wholly unexpected since the normal expectation was the opposite, that is, if bristle tufts were removed from a brush, the brush would not perform as well.While the present inventors' solution to the aforementioned problems may seem simple in retrospect, it nevertheless has created an improved cleaning concept using a low cost brush which subjects the carpet to less wear.

摘要： A portable extraction surface cleaner apparatus wherein a surface to be cleaned is heated to an elevated temperature and a cleaning fluid is applied to the surface to be cleaned sequentially or simultaneously. The cleaning fluid is removed from the surface by suction from a vacuum source. Power is applied alternatively or simultaneously to a heating element and to the vacuum source for recovering the deposited cleaning fluid.
