Provided is a vacuum cleaner including a cleaner body; a moving wheel provided at each of both side surfaces of the cleaner body, rotated for travelling of the vacuum cleaner and configured to support the cleaner body to be rotatable in normal and reverse directions; a wheel motor assembly connected to the moving wheel and configured to rotate the moving wheel for the travelling of the vacuum cleaner; a main motor provided inside the cleaner body, located at a rear side further than a vertical extension line of a rotating center of the moving wheel and driven to suction dust; and a battery provided inside the cleaner body, located at the rear side further than the vertical extension line of the rotating center of the moving wheel and configured to provide electric power to the main motor and the wheel motor assembly, wherein a center of gravity of the cleaner body is located at a rear of the vertical extension line of the rotating center of the moving wheel due to an arrangement of the main motor and the battery.

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 hand vacuum cleaner comprises a main body has a driving handle and houses a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation wherein the driving handle has a hand grip portion that extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end above the lower end. An air treatment member has a dirt collection region having an openable door provided on a front end of the air treatment member.

A cleaner for collecting dust is provided. The cleaner includes a suction head, a dust collector having a first end mounted on the suction head and including a first dust collecting chamber, an extension member slidably mounted on the dust collector at the other end opposite to the first end of the dust collector, and a first dirt removing member disposed at one end of the extension member and having elasticity.

A dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

Embodiments of a unified airflow system for ultraviolet disinfection devices are disclosed. One embodiment of the present disclosure includes a unified airflow assembly and a control unit. The unified airflow assembly provides a shared airflow passage between a UV source and an airflow accessory capable of extracting contaminants from a target surface using a suction airstream. The UV source may be fluidically disconnected from the airflow accessory. The unified airflow assembly may include at least one air restriction unit in the shared airflow passage for manipulating a suction airstream therein. The control unit may be configured to drive the at least one air restriction unit to restrict the suction airstream to only one of the UV source and the airflow accessory.

A cleaning system and a base station. In a working process, an airflow is generated by a drawer, to draw garbage on the ground on a traveling path into a dust box. Before the airflow entering the dust box is discharged outside a cleaning robot, the airflow flows through an air filter, and dust carried by the airflow is filtered out under a filtering function of the air filter. When dust accumulation in the air filter needs to be cleaned or the dust box needs to be emptied, the air filter is driven by a dust cleaner to vibrate, so as to shake off dust in the air filter, and the garbage in the dust box is collected by using a collector of the base station.

A cleaner includes a suction unit, a main body including a cyclone unit for separating dust from air suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit. A filter unit is disposed inside the cyclone unit for filtering the air, and a movable unit disposed inside the cyclone unit includes a cleaning part for cleaning the outer circumference of the filter unit. An operation unit disposed outside the main body moves the movable unit and the cleaning part to remove dust from the outer surface of the filter unit.
