VACUUM TOOLS
A vacuum tool is configured to be removably coupled to a hose or wand of a vacuum. The vacuum tool comprises a first portion, a second portion, a flexible portion and a mechanical joint. The first portion and the second portion are connected by the flexible portion and coupled by the mechanical joint, so these portions are in fluid communication from various angles. And the mechanical joint comprises a detent and multiple recesses coupled to the detent. As a result, a user can use the vacuum tool in various situations more conveniently by bending the mechanical joint.
CLEANER HEAD FOR A VACUUM CLEANER
A cleaner head for a vacuum cleaner includes a suction cavity having an opening through which debris enters the cleaner head, and an air outlet, and an agitator mounted in the suction cavity in a cantilevered manner for rotation relative thereto. The agitator is conical in shape and has a first, free end and a second end which has a larger diameter than the first end. The air outlet is located adjacent the free end of the agitator.
Replacement head for a vacuum
A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber that has a sealing surface and at least one opening. The opening is provided to allow air, dust and debris to be drawn into the dust chamber during use. The sealing surface defines a sealing surface plane and the opening defines an opening place. The relative angle between the sealing surface plane and the opening plane is preferably between about −20 degrees and +150 degrees. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.
AGITATOR FOR A SURFACE TREATMENT APPARATUS AND A SURFACE TREATMENT APPARATUS HAVING THE SAME
A surface cleaning head includes a housing having a front side and back side, a brush roll rotatably mounted to the housing within a suction conduit and having at least a portion proximate the opening of the suction conduit, a leading roller mounted to the housing in front of the brush roll, and a drive mechanism operatively coupled to the brush roll and the leading roller for driving the brush roll and the leading roller at same time. The brush roll includes an agitator body and a first bristle/flap arrangement comprising a first deformable flap extending from the agitator body and a first bristle strip and/or row of tufts extending from the agitator body and disposed adjacent to the first deformable flap. The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.
METHOD AND APPARATUS FOR ATTACHING A FLOOR TOOL TO A VACUUM FRAME
An apparatus is provided for attaching floor tools to a wheeled vehicle. The apparatus includes a mounting frame configured to secure to a frame of the wheeled vehicle and a floating frame rotatably attached to the mounting frame. The apparatus also includes pickup tubes attached to the floating frame. The pickup tubes are configured to attach to the floor tools. The floating frame is configured to move relative to the mounting frame based on undulations in a floor surface over which the floor tools travel. In other embodiments, a method is provided for assembling the apparatus. In still other embodiments, a method is provided for using the above apparatus with the wheeled vehicle. In still other embodiments, a wheeled vehicle is provided that includes the above apparatus and the one or more floor tools attached to the wheeled vehicle with the apparatus.

VACUUM CLEANER
A vacuum cleaner includes a housing having a suction nozzle opening, a source of suction in fluid communication with the suction nozzle opening for generating a working air stream through the housing, and a multiply-adjustable debris collecting blade coupled along the rear of the suction nozzle opening for collecting debris.
Cleaner head
A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.

The opening is provided to allow air, dust and debris to be drawn into the dust chamber during use. The sealing surface defines a sealing surface plane and the opening defines an opening place. The relative angle between the sealing surface plane and the opening plane is preferably between about 20 degrees and +150 degrees. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.
REPLACEMENT HEAD FOR A VACUUM
A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber, a first connector lip and a second connector lip. An opening is provided that allows air, dust and debris to be drawn into the dust chamber during use. The connector lips are provided for attachment to a vacuum device. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.
