The suspension unit is configured to be raised or lowered relative to the lifting unit. The lifting unit includes a lifting drive motor including a rotatable shaft disposed in parallel with a direction in which the suspension unit is configured to be raised or lowered, and a transmission unit configured to transmit a rotation force of the lifting drive motor to the suspension unit.

A cleaning robot includes a main body, a drive assembly and a cleaning assembly. The main body includes a bottom part. The cleaning assembly includes a mounting part, a wiping part and a release part. The mounting part is positioned on the bottom part. The mounting part includes a first rail, a second rail, and a first positioning part. The wiping part is positioned on the mounting part and includes a second positioning part, the wiping part is movable from first ends of the first rail and the second rail to second ends thereof until the second positioning part abuts against the first positioning part whereby the wiping part is fixed on the mounting part. The release part is positioned on the mounting part and configured to separate the second positioning part from the first positioning part whereby the wiping part is detached from the mounting part.

A cleaning robot includes a main body and a cleaning module. The main body is configured to move on a floor along a travelling direction. The cleaning module includes a first shaft and some first roller sets. The first shaft is connected with the main body. The first shaft extends along a first axis perpendicular to the travelling direction. The first roller sets are separated from each other. Each first roller set includes a first bearing, a first tire and a first flexible structure. The first shaft penetrates through the first bearing. The first tire includes a first cleaning surface configured to abut against the floor. The first flexible structure includes a first inner surface and a first outer surface. The first inner surface abuts against the first bearing. The first outer surface abuts against the first tire. The first flexible structure has a first elasticity.

An example robotic device includes a mobile base and a base linkage. The base linkage has a first end and a second end where the first end is connected to the mobile base. The robotic device also includes a first end effector connected to the second end of the base linkage. The first end effector includes a shovel tool. The robotic device additionally includes an actuated control arm having a first end and a second end. The first end of the actuated control arm is connected to the second end of the base linkage. The robotic device further includes a second end effector connected to the second end of the actuated control arm. The second end effector includes a sweeping tool. The actuated control arm is configured to move the sweeping tool to engage with the shovel tool to sweep one or more objects onto the shovel tool.

A fast detachable automatic cleaning device includes a driving assembly and a cleaning assembly. The driving assembly includes a transmission shaft and at least one protrusion block that is a formed integral with the transmission shaft. The cleaning assembly includes a seat, a bearing sleeve connected to the seat, and a cleaning portion surrounding the seat. The bearing sleeve includes an assembly space, at least one track and at least one fixing hole. The driving assembly may be in a simplified structure through the formed integral of the transmission shaft and the protrusion block. Further, the protrusion block may be securely fastened in the fixing hole to enhance the assembly strength of the transmission shaft and the bearing sleeve to solve issues of a complicated structure and insufficient strength of convention solutions.

A robot cleaner enables a wet cleaning, has a replaceable cleaning unit, and ensures a sufficient friction force for doing a wet cleaning of a floor. The robot cleaner includes a frame including a wheel for driving, a replaceable cleaning unit formed at a lower part of the frame to clean a bottom surface and disposed in front of the wheel, a tank disposed at an upper part of the wheel and configured to supply fluid to the cleaning unit, a pump configured to pump the fluid contained in the tank such that the fluid contained in the tank is supplied to the cleaning unit, a hose configured to extend to the pump and the upper part of the cleaning unit and through which the fluid pumped by the pump flows, and a bumper formed on a side of the frame.

The cleaning device includes a water injection member and a mopping cloth cleaning member. The water injection member is configured to wet the mopping cloth of a cleaning robot. The mopping cloth cleaning member which reciprocates up and down to flap the mopping cloth of the cleaning robot, in order to clean the mopping cloth of the cleaning robot.

A robotic mop includes one or more mop assemblies that may be used for support, mobility, and/or scrubbing. The mop assemblies may be operated to both scrub and move the robotic mop along the intended path. For example, the robotic mop may operate the mop assemblies in this way by rotating the mop assemblies in one or more directions at various different speeds, by tilting the mop assemblies (whether or not while rotating the mop assemblies at the time), and so on. In this way, the robotic mop may be able to move while scrubbing with various amounts of force without disrupting navigation.

A lifting device for a mopping roller of a cleaner robot is provided. The cleaner robot includes a robot body, and the robot body is disposed with a cleaning device. The cleaning device includes the mopping roller, and the mopping roller is disposed with a rag. The lifting device is disposed inside the robot body and includes a driving mechanism. The driving mechanism is connected with the cleaning device. The robot body is provided with a roller-support frame, and the cleaning device is disposed on the roller-support frame. Therefore, a lifting device for a mopping roller of a cleaner robot that is simple in structure, flexible in use, accurate in control of lifting and high in automation, is realized.

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.
