A vacuum accessory tool has a nozzle body with upper and lower housings, a working air conduit provided on the nozzle body and adapted to be connected to a suction source remote from the nozzle body, a suction nozzle in fluid communication with the working air conduit, and a rotatable retaining ring securing the upper and lower housings together.

Vacuum accessory tool

A vacuum cleaner includes a suction nozzle and a dirt separating and collecting system. The dirt separating and collecting system can include a bagless filter module and a bagged filter module that can be interchanged to convert the dirt separating and collecting system between a bagless configuration and a bagged configuration.

Vacuum cleaner

A vacuum accessory tool comprises a nozzle body defining an interior, with an opening formed in the nozzle body and a working air conduit provided on the nozzle body in fluid communication with the opening via the interior. A hair removal assembly is associated with the nozzle body, and can include nubs from a flexible polymeric material adapted to generate an electrostatic charge when the tool moves over and in contact with a carpet surface.

A motor driven roller support assembly includes a motorized roller having a cylindrical outer surface that is configured to rotate, a support frame within which the roller is mounted, and a roller support connected to the support frame and engaging the outer surface of the motorized roller. The roller support may include a pair of support wheels for contacting the outer surface of the motorized roller, and include a pivot whereby the roller support is moveable relative to the support frame. The assembly may be integrated with a transfer conveyor, such as a right angle transfer having transfer blades that include belts driven by the motorized roller. The roller support engages the motorized roller in a direction that is generally opposite from the direction in which the belts engage the motorized roller to thereby counteract forces imparted by the belts on the motorized roller.

Motor driven roller support

A vacuum cleaner includes a dirt separating and collecting system. The dirt separating and collecting system can include an air-permeable filter material, and a helical inlet guide. Dirt entering the helical inlet guide within a working airstream is visible to the user through an at least partially transparent housing.

An accessory tool for a vacuum cleaner comprises an elongated body having a plurality of furrows for imparting flexibility to the accessory tool. The elongated body is further be made of a material that is selected to impart flexibility to the accessory tool so that the longitudinal axis of the elongated portion can be bent about a radius through an angle up to 45&#xb0; without kinking or breaking in a direction transverse to and laterally of elongated cross-sectional configuration.

Flexible crevice tool for vacuum cleaners

A vacuum accessory tool comprises a housing that defines a suction nozzle and a hair removal assembly associated with the suction nozzle. In one embodiment, the vacuum accessory tool further comprises an agitator assembly located in the suction nozzle and driven by an air turbine. In another embodiment, an impeller associated with the air turbine is weighted to prevent build-up of hair and other debris at the impeller.

A vacuum cleaner and vacuum cleaner system comprises a dirt separating and collecting system. The dirt separating and collecting system can include a filter module having a filter bag, wherein the inlet to the filter bag is helical and dirt entering the filter bag is visible to the user. Optionally, the filter bag filter module can be interchanged with a bagless filter module, which may include a conventional cyclone separator.

Vacuum cleaner and vacuum cleaner system

A cleaning composition for treating a surface comprises a purified enzyme and an enzyme denaturant system. The enzyme denaturant system is configured to denature the purified enzyme such that any residue remaining on the surface after the treatment of the surface is virtually free of active purified enzymes.

Enzyme cleaning composition and method of use

A vacuum cleaner includes a base assembly with an upper housing, an agitator mounted in fixed position relative to the upper housing, an agitator height control mechanism for selectively adjusting the vertical height of the agitator relative to the surface to be cleaned, and a sole plate. The sole plate includes a suction nozzle opening for the base assembly and during operation of the agitator height control mechanism, the sole plate moves relative to the upper housing so that the distance between the suction nozzle opening and the surface to be cleaned remains essentially the same, regardless of the position of the agitator.

Vacuum cleaner with agitator height control mechanism

An upright vacuum cleaner has a compact, cylindrical exhaust filter assembly that is easily accessible by a user. The filter is removably mounted in a housing between an exhaust outlet aperture and a suction source outlet. A filter locking lug is associated with the filter element and the housing for removably securing the filter element to the housing to the filter frame. An upright vacuum cleaner has a pre-motor filter assembly that is highly visible to a user and accessible thereby.

Vacuum cleaner and filters therefor

A filter assembly for a vacuum cleaner comprises a filter carrier and a filter element. The filter carrier has a curved rear surface and a pair of protrusion for mounting the filter carrier to the vacuum cleaner.

Filter for a vacuum cleaner

A vacuum cleaner with a first cyclonic dirt separation and a secondary cyclonic dirt separation and a bottom dirt-collecting bin beneath the first cyclone separator and a filter beneath the dirt cup and between the dirt cup and a suction source inlet. The secondary cyclones oriented generally perpendicular to the first cyclone separator. A separator plate separates the cyclone separator from the dirt cup. Fins project from a sidewall of the dirt tank, and fingers projecting from a bottom wall of the dirt tank. A hollow standpipe in the dirt cup transports working air from the cyclone separator outlet to the filter.

Vacuum cleaner with multiple cyclonic dirt separators and bottom discharge dirt cup

A vacuum cleaner with cyclonic dirt separation and a bottom discharge dirt cup beneath the cyclone separator and a filter beneath the dirt cup and between the dirt cup and a suction motor inlet. A separator plate separates the cyclone separator from the dirt cup. Fins project from a sidewall of the dirt cup, and fingers projecting from a bottom wall of the dirt cup. A hollow standpipe in the dirt cup transports working air from the cyclone separator outlet to the filter.

Vacuum cleaner with cyclonic dirt separation and bottom discharge dirt cup with filter

A vacuum cleaner comprises a cyclonic separator having a first cyclone and a plurality of downstream secondary cyclones. The first cyclone comprises a side wall defining a first cyclonic chamber, and the secondary cyclones each comprise a side wall defining a second cyclonic chamber. A dirt cup assembly is mounted below the cyclonic separator to collect contaminants separated in the first and second cyclonic chambers. The secondary cyclones can be arranged around the first cyclone side wall and form a gap between adjacent secondary cyclones so that the first cyclone side wall is exposed at the gap. A working air conduit can extend through the first cyclone and the dirt cup assembly to couple the secondary cyclones to a suction source located below the dirt cup assembly. Furthermore, the secondary cyclones can have a vortex stabilizer.
