A surface cleaning apparatus may include a cleaner body and a dust cup coupled to the cleaner body. The dust cup may be configured to pivot between at least three indexed positions.

A dust collector with convenient loading and unloading dust collecting barrel includes a base plate fixed on an outer periphery of a bottom of an air guide cylinder, an operation unit whose end is pivotally arranged on the base plate, linking members disposed on said operation unit and connected to a dust collecting barrel lid located under the air guide tube. Accordingly, when a user lifts up the operation unit, the linking members move the dust collecting barrel lid upwards. The upward movement separates the dust collecting barrel lid from the dust collecting barrel, so the dust collecting barrel is easily detached. The action of swinging the operation unit swings down allows the linking members to move the dust collecting barrel lid downwards, so the dust collecting barrel lid closes the dust collecting barrel. Therefore, the user loads and unloads the dust collecting barrel quickly and conveniently.

An electric vacuum cleaner apparatus includes: a station, an electric vacuum cleaner attachable to the station, and plural attaching detectors which can detect the electric vacuum cleaner is attached in the station. The electric vacuum cleaner includes a cleaner body; a tubular part connected to the cleaner body and sucks in dust; and a primary dust container that stores dust sucked in with the tubular part. The station includes a secondary dust container that stores dust discharged from the primary dust container. The electric vacuum cleaner apparatus permits transfer of dust from the primary dust container to the secondary dust container when at least two of the plural attaching detectors have detected the attaching of the electric vacuum cleaner to the station. The electric vacuum cleaner apparatus can reliably confirm the vacuum cleaner is placed at a correct position on the charging station so that dust to be discarded from the primary dust container to the secondary dust container does not leak around the electric vacuum cleaner apparatus.

A hand vacuum cleaner may have an air treatment member and a pre-motor filter downstream from the air treatment member. A suction motor and fan assembly may be is positioned downstream of and below the pre-motor filter, a post motor filter may be positioned downstream of the suction motor and fan assembly and in the lower end of the hand vacuum cleaner. A clean air outlet may be positioned below the suction motor and fan assembly whereby air travels downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter and in an upper end of the hand vacuum cleaner. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner. The clean air outlet may be positioned below the suction motor and fan assembly whereby air may travel generally downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.

A surface cleaning apparatus has a cyclone chamber and a dirt collection chamber. The cyclone chamber has a sidewall extending from a first end to an axially opposed second end. At least a portion of the dirt collection chamber is aligned with first end of the cyclone chamber and radially outwardly of a solid portion of the vortex finder.

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 surface cleaning apparatus comprises an air treatment member having a first end, a longitudinally spaced apart second end, an air inlet and an air outlet comprising an outlet conduit; an air flow path extending from a dirty air inlet to a clean air outlet and including a suction motor and the air treatment member; a pre-motor filter positioned in the air flow path downstream from the outlet conduit; and, an agitation member operatively engageable with the pre-motor filter.

An autonomous mobile robot includes a body, a drive supporting the body above a floor surface, a light-propagating plate positioned on the body and having a periphery defining a continuous loop, light sources each being positioned to direct light through a portion of the plate to a portion of the continuous loop, and a controller to selectively operate the light sources to provide a visual indicator of a status or service condition of the autonomous mobile robot. The drive is configured to maneuver the mobile robot about the floor surface.

A surface cleaning apparatus comprising a surface cleaning head, a rigid air flow conduit and a hand vacuum cleaner removably mountable to an outlet end of the rigid wand. The hand vacuum cleaner comprises a main body, a cyclone provided at the front end of the hand vacuum cleaner, an inlet passage positioned at an upper end of the cyclone and a hand vacuum cleaner electrical connector provided on the front end of the hand vacuum cleaner adjacent the inlet passage. The hand vacuum cleaner electrical connector is releasably connectable with the outlet end electrical connector of the rigid wand. When the hand vacuum cleaner is mounted to the outlet end of the rigid wand, the longitudinally extending passage axis extends in a same direction as the cyclone axis of rotation and the suction motor axis of rotation extends in the same direction as the cyclone axis of rotation.
