Disclosed herein is an intelligent robot cleaner. The intelligent robot cleaner primarily senses foreign matter sucked through a suction unit under the control of a control unit, and secondarily senses an article collected in a collection unit, if articles other than the foreign matter are sensed, thus allowing a use to recognize accurate information about the article collected in the collection unit and preventing valuables or small articles from being lost. The intelligent robot device may be associated with an artificial intelligence module, a unmanned aerial vehicle (UAV), a robot, an augmented reality (AR) device, a virtual reality (VR) device, devices related to 5G services, and the like.

A vacuum collection vehicle may include a chassis, a vacuum container supported by the chassis, a vacuum source separated from the vacuum container by an intermediate wall and a filter. The vacuum source is in pneumatic connection with the filter through the intermediate wall. A plurality of discharge conduits extend through the intermediate wall, extend over and above the filter, along the roof of the vacuum container. The plurality of discharge conduits have a plurality of respective outlets at different locations within the interior of the vacuum container for discharging collected material into different collection receptacles. The filter is sandwiched between the intermediate wall and the plurality of discharge conduits.

The invention is in the field of a cleaning machine for a road or pavement or gutter. These machines are used to remove objects, such as small items, such as leaves, and dirt from a road or the like, using a broom system for cleaning the road or the like, and typically a storage for removed objects and dirt.

A cleaner head for a vacuum cleaner includes a laser diode for illuminating debris located upon a region of a work surface located in front of the cleaner head with green light.

A cleaner head for a vacuum cleaner includes an optical system located towards one side of the cleaner head. The optical system includes a light source and at least one light shaping component for receiving light emitted from the light source and directing the light towards a planar work surface on which the cleaner head is disposed to illuminate debris located upon a region of the work surface. This region upon which debris is illuminated is in the shape of a sector. A central axis of the sector is aligned at an angle in the range from 35 to 65° to a front edge of the cleaner head, and one of the radii bounding the sector is aligned at an acute angle of less than 20° to the front edge of the cleaner head.

A cleaner hanger assembly, comprising a hanger (30), a charging bottom plate (20), an accessory frame (40), a hanger column (50) and a base (60). The charging bottom plate (20) can be used in cooperation with the hanger (30), so that a charging operation can be performed while the cleaner is hung on the hanger (30) whether when the cleaner is in a hanging state or in a floor-standing state, and the charging bottom plate (20) can also be detached for separate use. The hanger (30) can be connected to the accessory frame (40) to form a wall hanger assembly; or the hanger (30) can be connected to the base (60) by means of the hanger column (50), and the accessory frame (40) is fixed in the middle of the hanger column (50) to form a floor-standing hanger assembly.

A debris blower (1) is disclosed comprising a fan housing (3), a fan (5) configured to generate an airflow through the fan housing (3), an electric motor (7) configured to power the fan (5), and a first battery accommodation space (9) configured to accommodate a battery unit (10) for supply of electricity to the electric motor (7). The debris blower (1) further comprises a first air cooling channel (11) fluidly connecting the first battery accommodation space (9) and the fan housing (3).

Disclosed are a cleaning module and a cleaner comprising same. The cleaning module, according to one aspect of the present specification, comprises: a housing communicating with a suction port of a main body of the cleaner, and comprising a suction space exposed to a bottom surface; a first hole disposed on one side surface, perpendicular to a cleaning direction, of the housing; and a first opening/closing device comprising a first shielding member for enabling communication with the suction space by selectively opening/closing the first hole.

Provided is a method for controlling a robot cleaner including a first operation of identifying that a manual cleaner and the robot cleaner are turned on, a second operation of identifying, by the robot cleaner, a location of the manual cleaner, a third operation of moving, by the robot cleaner, to a location within a first set distance from the manual cleaner, and a fourth operation of stopping the movement of the robot cleaner when the robot cleaner is located at the location within the first set distance from the manual cleaner while the manual cleaner is moving, and performing, by the robot cleaner, cleaning while moving when the robot cleaner is located at a location within a second set distance from the manual cleaner.

A portable surface cleaning apparatus has a main body and air treatment member assembly is removably mounted to the main body. The air treatment member assembly air outlet and/or the suction motor inlet end is provided at the lower end of the air treatment member assembly when the surface cleaning apparatus is located on a floor and a pre-motor filter underlies the air treatment member assembly and/or the suction motor.
