An upright surface cleaning apparatus may have a surface cleaning head with a central longitudinal axis extending between its front and rear ends. An upright section may be mounted to the surface cleaning head and may be moveable between a generally upright position and a rearwardly inclined in use position. The upright section may include an air treatment member assembly and a suction motor. The air treatment member assembly may include an air treatment member and a dirt collection region that is positioned laterally from the air treatment member. The suction motor may be positioned below at least one of the air treatment member and the dirt collection region. The first and second laterally opposed sides and one of the front side and the rear side of the air treatment member assembly may be generally rectangular in top plan view when the upright section is in the upright position.

A multi-mode cleaning apparatus with suction may include a wand with a handle, a suction motor for providing suction, a bare floor unit configured to be movable by the wand and fluidly coupled to the suction motor, and a sweeper unit configured to be movable by the wand and fluidly coupled to the suction motor. The bare floor unit is configured for use in a suction only mode. The sweeper unit includes a rotatable brush roll and is configured for use in a brush roll only mode or a suction and brush roll mode.

Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.

Embodiments are directed to a vacuum cleaner and removably attachable filter. 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.

A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.

A method and apparatus are provided for coupling a first and second wheeled vehicle. The apparatus includes a first area with a stop to engage an undersurface of the first wheeled vehicle and a second area with spaced apart openings to receive wheels of the second vehicle. The apparatus also includes a hook member positioned between the first and second areas and including surfaces to engage a perimeter of the frame of the first wheeled vehicle. The method includes engaging a perimeter of the frame of the first wheeled vehicle with the hook member. The method further includes rotating the stop about an engagement point between the hook member and the frame of the first wheeled vehicle until the stop engages an undersurface of the frame. The method further includes positioning a pair of wheels of the second vehicle in the spaced apart openings.

An upright surface cleaning apparatus comprises a surface cleaning head, a cleaning unit moveably mounted to the surface cleaning head between a generally upright position and a rearwardly inclined in use position, a push handle and an above floor cleaning assembly. The cleaning unit comprises an air treatment member and the push handle is rotatably mounted with respect to the cleaning unit. The above floor cleaning assembly comprises a flexible conduit having an inlet end and an outlet end, wherein in a floor cleaning mode a first portion of the flexible conduit having the outlet end is located on the second lateral side of the air treatment member and a second transverse portion of the flexible conduit extends from the second lateral side of the air treatment member over the upper end of the air treatment member to the first lateral side of the air treatment member wherein the second transverse portion is vertically spaced from the rotational joint.

A hand vacuum cleaner has a cyclone assembly comprising a first stage cyclone and a second stage cyclone. The cyclone assembly has an openable front end moveable between a closed position and an open position wherein, when the openable front end is in the open position, the first stage cyclone, the second stage cyclone and the inlet conduit are opened.
