A drone for cleaning an outer wall of a high-rise building is configured to float and move in the air. The drone includes a drone main body and a floating transfer unit for floating and moving the drone main body in the art. The drone main body has a camera unit provided to photograph the exterior of a building and driving wheels on one surface thereof to be guide to the exterior of the building. The drone main body further has a buffer angle member to cushion an impact with the building and a washing nozzle unit which sprays water onto and washes the exterior of the building. Accordingly, by cleaning the exterior or a window of a skyscraper using the drone, there are the effects of reducing the costs of cleaning a skyscraper, simplifying a cleaning operation, preventing human accidents due to falls, and reducing cleaning time.

An autonomous coverage robot includes a chassis, a drive system configured to maneuver the robot, and a cleaning assembly. The cleaning assembly includes a cleaning assembly housing and at least one driven sweeper brush. The robot includes a controller and a removable sweeper bin configured to receive debris agitated by the driven sweeper brush. The sweeper bin includes an emitter disposed on an interior surface of the bin and a receiver disposed remotely from the emitter on the interior surface of the bin and configured to receive an emitter signal. The emitter and the receiver are disposed such that a threshold level of accumulation of debris in the sweeper bin blocks the receiver from receiving emitter emissions. The robot includes a bin controller disposed in the sweeper bin and monitoring a detector signal and initiating a bin full routine upon determining a bin debris accumulation level requiring service.

A multifunctional cleaning device includes a main body, a telescopic tube body, a cleaning head set and a control unit. Multiple drive units are mounted on one side of the main body. The main body has a detection unit for detecting cleaning range and path. The telescopic tube body is telescopically connected with the main body. The telescopic tube body has a first end and a second end. The first and second ends are respectively connected with the main body and the cleaning head set in communication therewith. The control unit is disposed in the main body to execute system control and judge received signals so as to give commands to the drive units for controlling the move of the main body.

The present disclosure provides a movable electric device. The movable electric device includes a movable device body and a contact detection electrode. The movable device body has an electric drive means. The contact detection electrode is mounted on the movable device body. When the contact detection electrode _contacts diffusible dirt, a resistance, capacitance or impedance of the contact detection electrode varies.

An optical navigation device comprising: a processing circuit; a first light source, configured to emit first light; a cover; at least one second light source, configured to emit second light toward the cover; and an first optical sensor, configured to sense first optical data generated according to the first light and to sense second optical data generated according to the second light on the cover. The processing circuit determines a dirtiness level of the cover based on the second optical data sensed by the first optical sensor. The optical navigation device can further comprise a second optical sensor. Also, an optical navigation device which can avoid the interference of another optical navigation device is also disclosed.

A cleaner includes a body forming an external appearance, and a spin-mop cleaning module configured to support the body and including at least one spin-mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side. The inclination angle of a lower surface of the spin mop is changeable relative to a horizontal plane.

A movable electronic apparatus includes a mobile apparatus body, a contact-type detection apparatus and a control circuit. The mobile apparatus body is provided with an electrical drive assembly that drives the mobile apparatus body to move; the contact-type detection apparatus is mounted on the mobile apparatus body, and the contact-type detection apparatus is configured and when the contact-type detection apparatus contacts dispersed dirt, an electrical signal outputted by the contact-type detection apparatus changes; the control circuit is mounted on the mobile apparatus body, and the control circuit is configured to determine whether the dispersed dirt is detected according to the magnitude of the amount by which the electrical signal outputted by the contact-type detection apparatus changes, and to control the electrical drive assembly to drive the mobile apparatus body to execute a dirt dispersion prevention action when determined that dirt that may be dispersed is detected.

A cleaner includes a body which forms an outer appearance; a mop module having at least one rag part which is provided to wipe a floor while rotating; and a detaching module comprising at least one catching portion which detachably catches the mop module to the body, and a manipulation button which is exposed outside, wherein when the manipulation portion is touched, the catching portion releases catching of the mop module.

A sweeping robot is described. The sweeping robot includes a base plate and a contact-type detection electrode, the contact-type detection electrode is mounted at a front portion of the base plate. When the contact-type detection electrode makes contact with dirt that may be dispersed, the resistance, capacitance or impedance of the contact-type detection electrode changes.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, a controller for controlling the operation of the autonomous floor cleaner, a tank adapted to hold liquid, and a carry handle joined with the tank and/or the housing. The carry handle is movable between different positions, including a position in which the autonomous floor cleaner can be lifted via the carry handle while an inlet and/or outlet of the tank is blocked.
