A control host adjusts a suction force of the suction unit or adjusts the degree of closure between the suction port of the suction device and the suctioned surface according to a detected result of the detecting device, and provides warning information for cleaning or replacing the filter.

A nozzle for use with a surface cleaning device is disclosed that includes a nozzle housing defining a dirty air inlet, at least a first caster coupled to the nozzle housing to allow for movement of the nozzle housing over a surface to be cleaned, and a caster locking arrangement coupled to the nozzle housing. The caster locking arrangement preferably includes at least a first locking member to transition the first caster between a locked configuration and an unlocked configuration, with the locked configuration limiting movement of the nozzle housing along a single axis during cleaning operations, and the unlocked configuration allowing for movement of the nozzle housing along a plurality of axes/directions during cleaning operations.

A robot cleaner is provided. The robot cleaner includes a driving unit, a memory storing a map for a space in which the robot cleaner is located, and a processor which controls the driving unit to drive the robot cleaner in a cleaning region included in the map based on information obtained through a sensor, controls the driving unit so as to identify types of obstacles located in the cleaning region while the robot cleaner drives in the cleaning region and change the driving direction of the robot cleaner at different distances for different types of obstacles.

The present disclosure relates to dust extractor (1) comprising a dust cyclone container (3) having a contaminated portion downstream an air inlet (2) and a clean portion downstream the contaminated portion, and a dust separating part (9) there between. The contaminated portion is provided with a dust container (59). The dust extractor (1) comprises a fine filter section (12) arranged adjacent to the dust cyclone container (3) and having a contaminated section and a clean section downstream the contaminated section, and a fine filter part (15) is adapted to be provided between the contaminated section and the clean section. An air channel (47) runs between a clean side of the dust cyclone container (3) and a contaminated side of the fine filter part (15). The dust extractor also comprises a mobility section (66) comprising wheels and a blower/fan motor (10) for drawing air from the air inlet (2) through the dust extractor. The dust cyclone container (3) has a center axis (48) along its longitudinal extension, and the fine filter part (15) is provided at a radial distance from the dust cyclone container (3) along a plane (P) perpendicular to the center axis (48) of the dust cyclone container (3), the plane (P) coinciding with the dust cyclone container (3) and a portion of the fine filter part (15). The blower/fan motor (10) is adapted to be powered at least partly by at least one onboard battery (61), and preferably two batteries (61), wherein the at least one battery (61) is arranged to be received in at least one battery slot (62) provided in the fine filter section (12) or in the mobility section (66).

A robotic system comprising a mobile robot including a body housing a rechargeable power source and first electrical contact means disposed on the body and a docking station including second electrical contact means, wherein the mobile robot is dockable on the docking station in order to charge the rechargeable power source. The first electrical contact means includes at least one electrical contact aligned on a first contact axis and the second electrical contact means includes at least one elongate contact, wherein when the robot is docked on the docking station such that electrical contact is established between the first electrical contact means and the electrical contact means. The at least one elongate contact extends in a direction that is transverse to the first contact axis which permits electrical contact to be established between the robot and the docking station while accommodating a degree of lateral and angular misalignment therebetween.

Disclosed herein is a method of controlling a cleaner including a movable body for suctioning and a following body for collecting the dust suctioned by the movable body, the method including: (a) acquiring an image for a view around the following body; (b) acquiring position information of the movable body in an real space, based on the image; (c) acquiring position information of an obstacle in the real space, based on the image; (d) setting a travel direction such that the following body avoids the obstacle to follow the movable body, based on the position information of the movable body and the position information of the obstacle; and (e) controlling the following body to travel in the set travel direction.

The present invention discloses a self-moving robot, comprising a self-moving module and at least one of a plurality of interchangeable working modules connected to the self-moving module; the working module further comprises a second energy unit, and the first energy unit comprises a chargeable battery, providing energy for the working module or the self-moving robot.
