A floor cleaning machine is provided, comprising a suction unit device, a suction bar which is operatively connectable, or operatively connected, to the suction unit device for fluid communication therewith, a holder which releasably holds the suction bar, a fixing device for releasably fixing the suction bar at the holder, and an overload protection device which is associated with the suction bar, wherein the overload protection device comprises at least one rotational bearing by way of which the suction bar is rotatable at the holder relative to the holder when an overload situation occurs.

An orbital single-brush machine that comprises a chassis which is configured to rest on the floor and is provided with at least one movement handle. The chassis is connected to a motor which is adapted to actuate with combined rotary and orbital motion a work tool that acts on the floor; the chassis comprises a first footing, which is at least partially substantially plate-shaped and is spaced apart from the floor, and a second footing, which is at least partially substantially plate-shaped, supports the motor and is arranged below the first footing, and is supported so that it can rotate freely by the first footing about an oscillation axis which is substantially parallel to the floor and substantially perpendicular to the direction of advancement of the machine. Shock absorbing means are provided which act between at least one portion of the first footing and at least one portion of the second footing.

The embodiments of the present application provide a cleaning device and a roller brush component. The roller brush component includes a mounting base, a roller brush frame, an adjusting mechanism, a first roller brush and a second roller brush. A notch is formed on one side of the mounting base. The roller brush frame is rotatablely connected with the mounting base. The adjusting mechanism is in driving connection with the roller brush frame to drive the roller brush frame to rotate. The first roller brush and the second roller brush are connected with the roller brush frame, and the roller brushes are positioned in the notch. The roller brush frame, the first roller brush and the second roller brush are configured such that the first roller brush and the second roller brush may have different ground clearances during rotation of the roller brush frame.

A cleaning robot, including: a housing; a moving module, and a control module, for controlling the moving module to drive the cleaning robot to move. When the cleaning robot moves on a working surface, a wiping unit is capable of directly or indirectly contacting the working surface to wipe the same. The cleaning robot includes a work execution state and a maintenance state. While the cleaning robot is switching from the work execution state to the maintenance state, the control module controls the cleaning robot to move from a work execution position corresponding to the work execution state to a maintenance position corresponding to the maintenance state. During at least a part of the process of the cleaning robot moving from the work execution position to the maintenance position, where the at least a part of the wiping unit is in a state of not contacting the working surface.

An autonomous cleaning robot (e.g., an autonomous vacuum) may employ a cleaning head for cleaning messes in an environment. The cleaning head may comprise an enclosure with a brush opening at a first side, a mop opening at a second side, and an outlet connected to a vacuum pump. The outlet may open to a cavity within the enclosure. The cleaning head may further comprise a brush roller configured at a front of the enclosure, a mop roller configured behind the brush roller in the enclosure, an actuator connecting the mop roller and brush roller to the enclosure, and a selection flap hinged at a top portion of the cavity. Each of the brush roller and mop roller may be externally exposed at the brush opening and mop opening, respectively, and the actuator may be configured to move the enclosure vertically.

An autonomous cleaning robot (e.g., an autonomous vacuum) may clean an environment using a cleaning head that is self-actuated. The cleaning head includes an actuator assembly comprising an actuator configured to control rotation and vertical movement of a cleaning roller, a controller, and a cleaning roller having an elongated cylindrical length connected to the actuator assembly. The cleaning head also includes a computer processor connected to the actuator assembly and a non-transitory computer-readable storage medium that causes the computer processor to map the environment based on sensor data captured by the autonomous vacuum. The computer processor may determine an optimal height for the cleaning head based on the map and instruct the actuator assembly to adjust the height of the cleaning head.

An autonomous cleaning robot (e.g., an autonomous vacuum) may use a sensor system to map an environment that may be used to determine where to clean. The autonomous vacuum receives visual data about the environment and determines a ground plane of the environment based on the visual data. The autonomous vacuum detects objects within the environment based on the ground plane. For each object, the autonomous vacuum segments a three-dimensional (3D) representation of the object out of the visual data and determines whether the object is static or dynamic. The autonomous vacuum adds static objects to a long-term level of a map of the environment and dynamic objects to an intermediate level of the map. The autonomous vacuum may further add virtual borders, flags, walls, and messes to the map.
