A floor vacuum cleaner for cleaning a floor surface has a chassis with a chassis frame for traveling over the floor surface. A suction nozzle aspirates an airflow in the region of the floor surface. The suction nozzle is mounted relative to the chassis in the direction of travel to the front left and front right in each case by way of a mounting arrangement formed of a journal and a guide. The mounting arrangement allows a tilting of the suction nozzle about the journals, a rotation of the suction nozzle about a longitudinal axis, and a vertical movement of the suction nozzle, but a movement of the suction nozzle in the longitudinal direction of the chassis is prevented.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

This invention relates to a suction head (10) for a vacuum cleaner and method of operation. The suction head (10) has a bottom surface (26) and one or more floor-engaging parts (36) adjacent to the bottom surface (26), an opening (24) in the bottom surface (26) and a rotatable brush (30) located at the opening (24). The suction head (10) has a front end (16) and a rear end (18), the front end (16) having a recess (22) in communication with the opening (24). A movable strip (42) is located in the recess (22), the movable strip (42) being movable between a first position and a second position, the bottom edge of the movable strip 4(2) being closer to the plane of the floor-engaging parts (36) in its first position than in its second position. At least one first element (54) is connected to the movable strip (42) and is able to project to the plane of the floor-engaging parts (36). At least one second element (56) is also connected to the movable strip (42), the second element(s) (56) being configured differently to the first element(s) (54), the second element(s) (56) being able to project to the plane of the floor-engaging parts (36) and being configured to move the movable strip (42) to a third position in use. The bottom edge of the movable strip (42) is closer to the plane of the floor-engaging parts (36) in its second position than in its third position. According to the method of operation, the movable strip (42) moves to its first position during backwards movement of the suction head (10) and to its third position during forwards movement of the suction head (10), the movable strip (42) moving to its third position in two stages.

A mobile cleaning robot can include a body, a drive wheel, and a plurality of skids. The drive wheel can be connected to the body and can be engageable with a floor surface of an environment. The drive wheel can be operable to move the mobile cleaning robot about an environment. The skids can be separate skids that can be connected to the body and can be engageable with the floor surface to support, together with the drive wheel, the mobile cleaning robot with respect to the floor surface.

A vacuum cleaner nozzle includes a sole provided with a lower face and a suction channel emerging into the lower face; and a front scraping member located at the front of a front edge of the suction channel and delimiting at least in part a central passage opening which is fluidly connected to the suction channel. The front scraping member generally has a V shape having an apex oriented towards a central part of the suction channel, the front scraping member including a first scraping branch extending in a first direction of extension and a second scraping branch extending in a second direction of extension, the first and second scraping branches being configured to orient waste, coming into contact against the front scraping member during a forward movement of the vacuum cleaner nozzle towards the central passage opening.

A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.
