A wheel assembly for a robotic cleaner may include a frame, a moveable arm pivotally coupled to the frame, a driven wheel rotatably coupled to the moveable arm such that the driven wheel pivots with the moveable arm, and a biasing mechanism configured to urge the driven wheel towards an extended position, the biasing mechanism being coupled to the frame and spaced apart from the moveable arm.

Autonomous carriers or totes that include vacuum units are provided. As the totes move or are moved through a warehouse carrying products, they collect debris. The debris can be analyzed at the tote, and actions can be performed based upon the analysis.

A vehicle includes a wheel to contact a surface having a reference surface plane in operation of the vehicle; a chassis; an axle housing having an axis which is normal to the reference surface plane; and an axle. The axle extends from the axle housing, to couple the wheel to the axle housing and to support rotation of the wheel relative to the axle housing to support motion of the vehicle across the surface in operation of the vehicle. A suspension system couples the wheel to the chassis and includes a linkage assembly having a first end pivotably coupled to the chassis and a second end pivotably coupled to the axle housing. The first end of the linkage assembly is spaced apart laterally from the second end of the linkage assembly along a longitudinal axis of the linkage assembly. The suspension system is configured to maintain the axis of the axle housing at an angle normal to the reference surface plane in response to an angular displacement between the chassis and the reference surface plane.

Disclosed herein are a wheel assembly and a robot cleaner including a main body and a wheel assembly coupled to the main body to guide movement of the main body. The wheel assembly has a rotation arm including a first end portion rotatably mounted on the main body, a drive wheel rotatably installed on a second end portion of the rotation arm opposite the first end portion, and an elastic member including a first end installed at the main body and a second end vertically moveably installed at the rotation arm opposite the first end, such that a reduction degree of a contact force due to a descent of the drive wheel.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

Disclosed are a robot cleaner. The robot cleaner includes: a cleaner body configured to move in an area and clean the area; and a sensor assembly provided in the cleaner body. The sensor assembly includes: a main sensor configured to be moveable between a sensing position where the main sensor protrudes out of the cleaner body and a settled position where the main sensor is inside the cleaner body; a sensor position changer configured to allow the main sensor to move between the sensing position and the settled position; and a stopper configured to restrict the sensor position changer from allowing the main sensor at the sensing position to move towards the settled position.

A surface cleaning apparatus such as a vacuum cleaner includes a suction source, a recovery container, and a base assembly with at least one agitator within an agitator chamber. The recovery container can be coupled to a separator assembly configured to remove dirt and debris from working fluid through the vacuum cleaner. In addition, a brake assembly can be provided on an upper portion of the base assembly and be configured to engage at least one wheel of the base assembly.

A robotic cleaner may include one or more driven wheels, one or more environmental sensors, at least one of the one or more environmental sensors configured to detect a first obstacle having a first vertically extending surface, one or more edge cleaning implements, and a controller communicatively coupled to the one or more driven wheels and the one or more environmental sensors. In response to detecting the first obstacle, the controller may be configured to cause the robotic cleaner to move through a rotation angle such that at least one of the one or more edge cleaning implements approaches the first vertically extending surface.

A cleaner includes a body, a left spin-mop module and a right spin-mop module configured to perform mopping, and a water supply module configured to supply water to the left spin-mop module and the right spin-mop module. The water supply module includes a water tank to store water therein, a pump to pressurize the water in the water tank to move the water to the left spin-mop module and the right spin-mop module, a first supply pipe connecting the water tank and the pump, a common pipe connected to the pump, the common pump configured to guide movement of the pressurized water from the pump, a first branch pipe configured to guide a first portion of the water in the common pipe to the left spin-mop module, and a second branch pipe configured to guide a second portion of the water in the common pipe to the right spin-mop module.

A moving robot and a control method thereof according to the present invention create a cleaning map including information on a travelable area of a cleaning area based on obstacle information, create a create a manufactured user map by changing forms and outlines by area with respect to a plurality of area configuring the cleaning map, and create a user map having a form similar to that of the cleaning are in a real indoor space by changing a form and an outline of a map including information on the travelable area according to an arear, so that a user easily recognizes a position of each area to input a cleaning command through the map, and a cleaning command with respect to an area which the moving robot cannot run is prevented from being input. Since the moving robot does not unnecessarily move an area, operation power consumption is reduced. The moving robot may run a cleaning area with limited power to efficiently clean the cleaning area.
