An autonomous cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes operating a drive system to move the cleaning robot in a forward drive direction along a first obstacle surface with a side surface of the cleaning robot facing the first obstacle surface, then operating the drive system to turn the cleaning robot such that the side surface of the cleaning robot faces a second obstacle surface, then operating the drive system to move the cleaning robot in a rearward drive direction along the second obstacle surface, and then operating the drive system to move the cleaning robot in the forward drive direction along the second obstacle surface.

Autonomous carriers or totes that include vacuum units are provided. As the totes move or are moved through a warehouse carrying products, they collect debris. The debris can be analyzed at the tote, and actions can be performed based upon the analysis.

A system providing a barrier for an autonomous floor cleaner includes an artificial barrier generator that radiates one or more infrared signals. An autonomous floor cleaner can be configured to detect the infrared signals, and can react by altering course. Methods for containing an autonomous floor cleaner within a user-determined boundary are disclosed.

An automatic guiding method for a self-propelled apparatus (10) is provided. The self-propelled apparatus (10) turns and irradiates when a signal light emitted by a charging dock (20) is sensed by a flank sensor (103), and changes its turn direction when another different signal light from the charging dock (20) is sensed by a forward sensor (102). The charging dock (20) switches to emit another signal light different from the signal light currently emitted when each time is triggered by the signal light emitted by the self-propelled apparatus (10). Repeatedly execute the above actions and make the self-propelled apparatus approach the light-emitting unit (202) until the self-propelled apparatus (10) reaches a charging position. It can accurately guide the self-propelled apparatus (10) to the charging position by arranging only two sensors on the self-propelled apparatus.

An air cleaner disposed in an indoor space is disclosed. The air cleaner according to an embodiment of the present invention includes a blowing device including a suction port and a discharging port, a fan motor configured to cause air flow, a purification unit installed in the blowing device to clean air, a flow conversion configured to change a flow direction of air discharged from the discharging port, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive feature information collected by the moving agent and associated with a structure of the indoor space, obtain a type of the indoor space by using the feature information, and control an operation of at least one of the fan motor and the flow conversion device by using the type of the indoor space to adjust at least one of an operation mode, a wind direction, and a wind volume.

A floor cleaner can include a housing adapted for movement over a surface to be cleaned and at least one edge cleaning brush provided on the housing. The edge cleaning brush includes multiple cleaning implements which rotate at different velocities. A gear system, such as a planetary gear system, can drive one cleaning implement at a lower speed than another cleaning implement.

The invention relates to a vacuum cleaner robot comprising a dust collector arrangement mounted on wheels, a suction hose and a floor nozzle mounted on wheels, where the floor nozzle is fluidically connected to the dust collector arrangement via the suction hose, also comprising a motorized fan unit for suctioning an air stream in through the floor nozzle, where the motorized fan unit is arranged between the floor nozzle and the dust collector arrangement in such a manner that an air stream suctioned in through the floor nozzle flows through the motorized fan unit and into the dust collector arrangement. where the dust collector arrangement comprises a drive device in order to drive at least one of the wheels of the dust collector arrangement, and where the floor nozzle comprises a drive device in order to drive at least one of the wheels of the floor nozzle.

The invention relates to a floor vacuum cleaner comprising a dust collector arrangement mounted on rollers and/or runners, a suction hose, a suction tube, and a floor nozzle, wherein the floor nozzle is fluidically connected to the dust collector arrangement via the suction tube and the suction hose, wherein the dust collector arrangement comprises a dust separator, wherein the dust collector arrangement comprises a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged so that an air stream suctioned in through the floor nozzle, the suction tube, and the suction hose flows through the motorized fan unit and into the dust separator, wherein the dust collector arrangement has a housing and the motorized fan unit is mounted on or in the housing, wherein the dust separator is mounted in the housing.

The present invention relates to a vacuum cleaner robot comprising a floor nozzle supported on wheels and a dust collection unit, wherein the floor nozzle comprises a driving device for driving at least one of the wheels of the floor nozzle, wherein one of the wheels, a plurality of or all of the wheels of the floor nozzle are omnidirectional wheels, wherein the floor nozzle comprises a base plate with a base surface, which, when the vacuum cleaner robot is in operation, faces the surface to be cleaned, the base plate having provided therein an air flow channel, which extends parallel to the base surface and through which air to be cleaned enters the floor nozzle, and wherein the floor nozzle comprises a rotating means for rotating the air flow channel about an axis perpendicular to the base surface.

An upright vacuum cleaner includes a main-body part (10) having a dust-collection chamber (14) fluidly connected to a motor chamber (13) via a coupling pipe (15). A fan (13f) and a motor (13m) are housed in the motor chamber. A cleaner head (20) is pivotably and fluidly connected to the main-body part and suctions air through a suction opening (23) when a suction force is generated by the fan and the motor in the motor chamber. A straight suction passageway (24) extends through a central portion of the interior of the cleaner head in plan view. One or more batteries (50) is/are disposed within the cleaner head spaced apart (outward) from the suction passageway in the plan view.
