A vacuum cleaner assembly basically includes a vacuum body, a first power source, an accessory, and a second power source. The first power source is configured to create flow through a suction path. The accessory is configured to be removably connected to the vacuum body. The second power source is configured to power the accessory. Each of the first and second power sources is configured to share power with the other of the first and second power sources.

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.

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.

The present disclosure discloses a mobile robot and a control method thereof. More particularly, when a movement is detected in an area to be cleaned, a mobile robot learns whether the detected movement is a behavior pattern of causing a foreign material or not. The mobile robot performs a suitable cleaning when the movement of causing the foreign material is found or detected later.

Embodiments of the present disclosure provide a self-cleaning control method of a cleaning device, a cleaning device, and a storage medium. The cleaning device is provided with at least one self-cleaning object. The control method includes: determining a current self-cleaning mode of the cleaning device according to a predetermined condition; and controlling the cleaning device to clean the self-cleaning object according to the determined current self-cleaning mode. Based on technical solutions in the embodiments of the present disclosure, different self-cleaning modes can be selected according to different dirt conditions of the cleaning device, thereby improving the selection flexibility of a self-cleaning mode of the cleaning device.

A cleaning device includes a cleaning device body and a replacement head. The cleaning device body includes an elongated handle, a housing and a replacement head mounting section. The replacement head has a pad that is intended to clean a surface, such as a floor and is removably attachable to the cleaning device body. The housing includes a circuit board having at least one sensor capable of sensing motion. The handle includes at least one button that can turn on/off either a vacuum source or a jet nozzle that sprays cleaner fluid. The cleaning device body further includes at least one light mounted thereon. The at least one light is illuminated when the button is pressed and then the at least one light remains illuminated until a predetermined amount of time has passed during which neither the button has not been pressed nor motion sensed by the sensor.

A street sweeper comprises a dirt container and a suction device. The suction device comprises a suction mouth, a suction channel and a suction fan. The suction fan generates a suction flow which leads into the dirt container. Furthermore, the street sweeper comprises a recycling system with a separating device. The separating device separates sucked-in dirty water from the dirt container into the recycling system. Furthermore, the street sweeper comprises a fresh-water tank in which fresh-water is stored. Furthermore, a cleaning device is provided by means of which at least a part of the recycling system can be cleaned. The fresh-water from the fresh-water tank is used for cleaning the recycling system.

An electric work machine according to one aspect of the present disclosure includes a motor, a first connector, a second connector, an energizing circuit, a manual switch, and a controller. The controller outputs a first control signal to the energizing circuit to electrically connect the first connector to the motor, increases an actual rotational speed of the motor at a first rate, outputs the first control signal to the energizing circuit to electrically connect the second connector to the motor, and increases the actual rotational speed at a second rate. The second rate is less than the first rate.

Disclosed are a robot cleaner. The robot cleaner includes: a cleaner body configured to move in an area and clean the area; and a sensor assembly provided in the cleaner body. The sensor assembly includes: a main sensor configured to be moveable between a sensing position where the main sensor protrudes out of the cleaner body and a settled position where the main sensor is inside the cleaner body; a sensor position changer configured to allow the main sensor to move between the sensing position and the settled position; and a stopper configured to restrict the sensor position changer from allowing the main sensor at the sensing position to move towards the settled position.
