The disclosure relates to a cleaning device comprising a driving roller, a driven roller, a flexible cleaning belt sleeved on the driving roller and the driven roller, a garbage collection box, a brush, a sewage collection tank, a clean water tank and a water squeezing roller. The garbage collection box is provided with a guide plate near one end of the cleaning belt. The sewage collection tank and the clean water tank are located downstream of the garbage collection box along the moving direction of the cleaning belt. The cleaning device is provided with a sewage collection tank and a clean water tank. Clean fluid in the clean water tank flows onto the cleaning belt to clean the cleaning belt, and the sewage water and excess water on the cleaning belt are squeezed into the sewage collection tank by the water squeezing roller.

SWEEPING ROBOT AND CLEANING MECHANISM THEREOF
20210219804 · 2021-07-22 ·

The disclosure discloses a cleaning robot and a cleaning mechanism thereof. The cleaning robot comprises a shell and a cleaning mechanism. The cleaning mechanism comprises a flexible roller, a motor for driving the flexible roller to rotate, a water squeezing roller, a roller brush, and a sewage collection tank. The sewage collection tank is located above the flexible roller. The water squeezing roller is disposed adjacent to the sewage collection tank. The center of the water squeezing roller is disposed in parallel with the center of the flexible roller, and the surface of the water squeezing roller is pressed against the surface of the flexible roller. The roller brush contacts the flexible roller. When the flexible roller rotates, the water squeezing roller presses sewage in the flexible roller into the sewage collection tank. The cleaning mechanism of the disclosure has strong squeezing capability, can reduce energy consumption, and reduce noise.

Cleaning robot and method of surmounting obstacle

A cleaning robot includes a detector configured to detect an obstacle; a determining portion configured to determine whether the cleaning robot is in an obstacle obstruction state; and a controller configured to control the first drive wheel to cross an obstacle and control the second drive wheel to cross the obstacle according to a detection result when the cleaning robot is in the obstacle obstruction state.

CLEANING ROBOT, CONTROL METHOD FOR SAME, AND CLEANING ROBOT SYSTEM
20210228050 · 2021-07-29 ·

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.

SURFACE CLEANING APPARATUS AND TRAY

A surface cleaning apparatus adapted for movement across a surface to be cleaned. The surface cleaning apparatus can dock within a storage tray and charge a power supply. Electrical contacts on the surface cleaning apparatus and the storage tray can be shielded when the surface cleaning apparatus is not docked within the storage tray. Furthermore, the storage tray can include a reservoir for a self-cleaning mode.

CONFIGURATION OF A CLEANING HEAD FOR AN AUTONOMOUS VACUUM

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.

SELF-ACTUATED CLEANING HEAD FOR AN AUTONOMOUS VACUUM
20210244250 · 2021-08-12 ·

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.

MAPPING AN ENVIRONMENT AROUND AN AUTONOMOUS VACUUM
20210244254 · 2021-08-12 ·

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.
