A surface cleaner may have various features including an engagement mechanism secured to an agitator support frame and positioned to be pivoted by an agitator lift lever as the agitator lift lever translates, the pivoting engagement mechanism lifting the agitator support frame and the agitator secured thereto from a lowered position to a raised position. Other features may include a projection to limit belt slack when the agitator assembly is raised, a compact detent mechanism for releasing a spine assembly in an upright surface cleaner, a compact motor drive assembly, a self-priming centrifugal pump, a fluid-dispensing system having a high flow operating state and a low flow operating state, and a clean-out tray in which a base of the surface cleaner may be docked.

The invention relates to a floor cleaning device (10; 110; 210; 310; 410), preferably a floor scrubbing device, particularly preferably a scrub vacuum floor cleaning device, comprising: a floor unit (12; 112; 212; 312; 412); a tool (24, 26; 124, 126) which is assigned to the floor unit (12; 112; 212; 312; 412) and which, in an operating state, contacts a floor surface (158); a guide member (14; 114; 214; 314; 414) for guiding the floor cleaning device (10; 110; 210; 310; 410); a joint assembly (16; 116) having a first pivot joint (18, 118) for pivoting the guide member (14; 114; 214; 314; 414) relative to the floor unit (12; 112; 212; 312; 412) about a first pivot axis (A); and a spring member (160; 260; 360; 460) for generating a spring force between the floor unit (12; 112; 212; 312; 412) and the guide member (14; 114; 214; 314; 414),
wherein the first pivot joint (18, 118) has a neutral position, characterized in that the spring member (160; 260; 360; 460) is operatively connected to the floor unit (12; 112; 212; 312; 412) and the guide member (14; 114; 214; 314; 414) in such a way that, when pivoting from the neutral position in a first pivot direction (S1) to a deflected position, a righting torque acting on the guide member (14; 114; 214; 314; 414) and resulting from the spring force about the first pivot axis (A) in the direction of the neutral position increases in a first angular range and decreases in a subsequent second angular range.

A container includes a tank body and a cover. The tank body defines an opening. The cover detachably covers the opening of the tank body. A sidewall of the tank body defines an accommodating groove. The cover includes a cover body and a plug-in piece extending from the cover body to the tank body. The plug-in piece is capable of extending into the accommodating groove. The container further includes a fixing piece, and the fixing piece detachably covers an opening of the accommodating groove and is capable of being buckled with the plug-in piece accommodated in the accommodating groove.

A cleaning device has a housing and a handle connected to the housing, with which the housing is moveable by hand with its underside over a floor. A brush roller is mounted in the housing so as to rotate and to be electrically rotatably drivable. The brush roller rests with a brush structure on the floor and the rotating brush roller picks up dirt particles with its brush structure as it passes over. A receiving compartment for dirt particles, which is arranged in the housing along the brush roller. A direction of rotation of the brush roller is towards the receiving compartment, so that dirt particles picked up from the floor by the brush roller are conveyed into the receiving compartment.

An autonomous floor-traversing robot includes: a wheeled body including a chassis and at least one motorized wheel configured to propel the chassis across a floor, the chassis defining an interior compartment disposed beneath a chassis ceiling; a cover extending across at least a central area of the chassis ceiling; and a graspable handle connected to the chassis and located outside the cover so as to be accessible from above the robot, the handle arranged to enable lifting of the robot. The chassis ceiling defines drainage channels configured to conduct the liquid away from the central area of the chassis ceiling.

New and novel structure(s) for cleaning surfaces have been disclosed. The device may include: a wiping surface, which may be disposable; a brush roll/larger debris gathering mechanism: a wiping surface, which may be disposable; a brush roll/larger debris gathering mechanism; a local debris storage and/or staging area, and a larger remote debris storage structure. Additionally, there are mechanisms and structures disclosed for powering the brush roll, activating the brush roll from an out of use position to an in use position, and moving the waste from one area to another. The invention at hand uniquely and inventively improves upon the known devices in this field.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The outlet section length is at least as long as the cyclone outlet port length.

A handheld vacuum cleaner including a suction inlet, a main body, a handle defined by a portion of the main body, a motor disposed within the main body operating a suction source, and a filter coupled to the main body. The filter is configured to separate debris from a flow of fluid drawn through the suction inlet. The filter includes a housing forming a first volume and a filter media forming a second inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container configured to store debris separated by the filter media from the flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.
