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.

A waste collection bag may be used by an autonomous cleaning robot (e.g., an autonomous vacuum) to store waste during a plurality of cleaning processes. The waste bag comprises a waste bag, a waste collection sachet, and an absorbent. The waste bag has a first side and a second side, where the first side has an opening for waste to enter, and is composed of filtering material. The waste collection enclosed sachet has a first side and a second side that connect to form a cavity. The waste collection enclosed sachet is tethered to the second side of the waste bag and is composed of dissolvable paper. The absorbent may absorb liquid waste and is located inside the cavity of the waste collection enclosed sachet.

A floor maintenance machine has an adjustable deck assembly. The floor maintenance machine includes a deck supporting a floor cleaning implement. A lifting arm extends away from a frame of the floor maintenance machine and is rotatably coupled to the deck. The lifting arm is rotatably actuatable to adjust a position of the deck relative to the frame. A support member is rotatably coupled to the frame and movably coupled to the deck. A stop member is supported by the deck and extends toward the lifting arm for selective engagement therewith. When the lifting arm is rotated relative to the frame to lift the deck, the stop member is driven into the lifting arm to limit relative rotation between the lifting arm and the deck beyond a set angle.

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.

A robot cleaner includes a first cleaning module including left and right spin mops configured to rotate clockwise or counterclockwise when viewed from above while being in contact with a floor, and a second cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while being in contact with a floor, the rolling member being spaced apart from the left and right spin mops in an anteroposterior direction. A controller controls rotational motion of the left and right spin mops and rotational motion of the rolling member.

A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller configured to detect a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit. When there is a change in position and a change in load current, a specific area of a floor is determined to be a contaminated area.

This invention relates to an industrial street sweeper and especially to a street sweeper having a floating sweeper brush which floats or rides over obstacles in the surface being cleaned.

A robot cleaner includes a body, a first rotating plate, a second rotating plate, a first mop, a second mop, a first support wheel, a second support wheel, and a first lower sensor. The first lower sensor is configured to sense a relative distance from a floor. The first lower sensor is located between the first support wheel and the second support wheel, and is located further away from the first rotating plate and the second rotating plate than the first support wheel and the second support wheel. The robot cleaner may move while being supported by the first mop, the second mop, the first support wheel, and the second support wheel, and easily avoid a cliff in which the floor suddenly drops.
