A surface cleaning apparatus can include a housing adapted to move across a surface to be cleaned, an edge brush, and a brushroll driven by a brush motor. The edge brush is connectable with a drive coupling for rotating the edge brush, and is indirectly driven by the brush motor via the brushroll. In one aspect, the edge brush and drive coupling comprise a modular unit removably coupled to the housing. In another aspect, the drive coupling can include a worm and a belt.

A surface cleaning apparatus includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. A brushroll is provided on the base, along with various wipers, squeegees, and/or fluid dispensers.

A cleaner head includes a housing having a suction port facing a cleaning target surface, a first rotary brush provided in the housing, a second rotary brush provided in the housing, and a suction area provided between the first rotary brush and the second rotary brush and connecting to the suction port. The first rotary brush and the second rotary brush rotate in directions opposite to each other.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

A vacuum cleaner includes an upright body mounted to a base that moves over a surface to be cleaned. A rotational coupling can be provided between the upright body and the base for coupling the upright body to the base for movement about at least one rotational axis. The rotational coupling can include at least a swivel joint. A cord rewinder can be provided above the swivel joint for storing and dispensing a power cord.

An upright vacuum cleaner (1) includes a brushroll (11); a motor assembly (200) including a motor housing (21) and a motor (22), in which a rotating axis of the motor (22) and a rotating axis of the brushroll (11) are disposed in a non-parallel manner, and the motor (22) drives the brushroll (11) rolling by a drive belt (13) and is rotatable between a first upright position of tensioning the drive belt (13) and a first oblique position of loosening the drive belt (13); a body assembly (300) including a body (31), a bridging member (32) and a dirt cup (37) mounted on the body (31), in which the bridging member (32) is rotatably connected with the motor housing (21) to make the body (31) rotatable between a second upright position and a second oblique position, and the motor (22) is moved by the bridging member (32) from the first oblique position to the first upright position when the body (31) moves from the second upright position to the second oblique position.

A vertical vacuum cleaner (1) is provided, including a brushroll (22); a motor assembly (200) including a motor housing (21) and a motor (22), in which the motor (22) is configured to drive the brushroll (22) to roll via a drive belt (13) and is rotatable between a first upright position where the drive belt (13) is tensioned and a first oblique position where the drive belt (13) is loosened; a body assembly (300) including a body (31) and a bridging member (32) rotatably connected with the motor housing (21); a lever driving device rotatably disposed to the motor housing (21) and having two ends respectively fitted with the bridging member (32) and the motor (22), in which the bridging member (32) is configured to drive the motor (22) to move from the first oblique position to the first upright position via the lever driving device.

A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.

A cleaning robot including at least a first cleaning roller brush and a second cleaning roller brush which are disposed to perform beating and cleaning on garbage on a to-be-cleaned surface, which is equivalent to beating and cleaning the to-be-cleaned surface at least twice. In addition, a high-power fan is used in combination to suck garbage that is agitated by the cleaning roller brushes into a dust box.

An upright vacuum cleaner includes a cleaning head for removing debris from a floor, a debris tube connected to the cleaning head for receiving the debris, and a steering handle connected to the debris tube. The upright vacuum cleaner also includes a hinge connecting the debris tube to the cleaning head such that the debris tube rotates relative to the cleaning head. The upright vacuum cleaner further includes braces to support the debris tube as the debris tube rotates relative to the cleaning head. The braces are disposed on opposite sides of the debris tube. Each brace includes a bearing connected to the cleaning head to allow the brace to rotate relative to the cleaning head.
