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.

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.

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.

Provided are a cleaning robot and a control method thereof. A control method of a cleaning robot using a rotational force of a plurality of rotation members as a motive power source for its driving, includes: driving the cleaning robot by rotating at least one of a first rotation member performing a rotational motion around a first rotation axis and a second rotation member performing a rotational motion around a second rotation axis; determining whether the cleaning robot reaches a wall surface during its driving; and driving the cleaning robot along the wall surface by rotating at least one of the first and second rotation members while maintaining one side surface of the cleaning robot to be in close contact with the wall surface when it is determined that the cleaning robot reaches the wall surface.

The present disclosure relates to a grinding head (1) for a floor grinding machine for grinding floor surfaces of stone or stone-like material. Such a grinding head (1) comprises a lower casing member (3), comprising a lower support (31) and an upwardly extending edge portion (32), and an upper casing number (2), comprising an upper cover (21) and a downwardly extending edge portion (22), wherein the upper casing member (2) is joinable to the lower casing member (3) by causing axially distal portions of the edge portions to bear on each other.

The invention is related to a mobile industrial autonomous device that can be used to perform different functions with the modules (8) of different features which can be easily changed by the user on the same platform. Although the main function targeted with the invention is the cleaning of indoor spaces, functions such as polishing, mowing, fertilizing, spraying etc. can also be provided by the robotic platform of the invention with modules that can be easily changed by the user. It will move automatically by the help of the lidar unit (4) and the camera units on the autonomous device, scan and map the environment and determine a route for itself accordingly and perform its function.

A cleaner includes a body forming an external appearance, a rotating plate provided at a lower side of the body, a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor, a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate, a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space, and a water supply module configured to supply water to the water supply space. The rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate.
