A hand vacuum cleaner has a main body comprising a suction motor, a front end, a rear end and a handle, the suction motor having a suction motor inlet end that faces the front end of the main body. A cyclone unit is positioned in the air flow passage upstream from the suction motor, the cyclone unit is removably mounted to the front end of the main body wherein the first cyclonic stage faces towards the suction motor inlet end. In another embodiment, the handle is provided on the top of the main body with a grip portion provided between a lower surface of the handle and an upper surface of the main body, the handle extending in the forward/rearward direction and having a front end, a rear end and a handle length that is greater than a length of the suction motor in the forward/rearward direction.

A autonomous cleaner includes: a cleaner body including a wheel unit for autonomous traveling; a suction unit provided to protrude from one side of the cleaner body, the suction unit sucking air containing dust; a sensing unit provided at the one side of the cleaner body; a dust container accommodated in a dust container accommodation part formed at the other side of the cleaner body, the dust container collecting dust filtered from sucked air; and a dust container cover hinge-coupled to the cleaner body to be rotatable, the dust container cover being provided to cover a top surface of the dust container when the dust container cover is coupled to the dust container.

A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.

An automatic filter cleaning system e.g for cleaning a filter in a vacuum cleaner. The cleaning system has an electrical motor that drives/rotates, directly/indirectly, a piston which directly/indirectly opens a filter cleaning valve. The filter cleaning valve may open for a filter cleaning back flow air stream that thus cleans the filter. The piston is spring loaded and a piston guide ensures that the energy accumulated in the spring and piston is released during the rotation of the piston, thereby shortly opening the filter cleaning valve.

A surface cleaning apparatus comprises a hand vacuum cleaner, a surface cleaning head and a rigid air flow conduit extending between the surface cleaning head and the hand vacuum cleaner. The hand vacuum cleaner comprises a main body and a removably mounted air treatment member. The air treatment member has an air inlet and the outlet end of the rigid air flow conduit is removably connectable in air flow communication with the air inlet.

A vacuum system for vacuuming is disclosed. The vacuum system includes a baseboard cleaning attachment, a floor cleaning attachment, and a hose attachment. Each of the attachments is selectively mounted to a hose of the vacuum system for vacuuming floors, baseboards and tight spaces. The baseboard cleaning attachment includes a brush head having a right-angled portion, and a curved portion. The brush head includes a neck to mount the brush head to the hose. The right-angled portion is aligned with the baseboard and is used to vacuum. The floor cleaning attachment includes an elongated tube, and an under furniture handle mounted to the elongated tube. The elongated tube includes a beater head with a beater. The elongated tube is mounted to the hose, and the under furniture handle is used vacuum under furniture. The hose attachment is in an S-shape for tight spaces.

A vacuum cleaner including: a suctioning unit; a main body including a cyclone part for separating dust from suctioned air and a dust container for storing the separated dust, and a body cover for opening and closing the lower side of the body; a filter unit, disposed in the body, for filtering air separated from the dust; an actuating unit capable of moving in the body between the outside of the filter unit and the inner circumference surface of the body; an operating unit disposed outside the body which operates in order to move the actuating unit; a transmission unit penetrating the body and connecting the actuating unit with the operating unit; and an elastic member disposed outside the body which elastically supports the operating unit.

An autonomous vacuum cleaner includes an outer housing and a separator assembly that is removably received by the autonomous vacuum cleaner. A portion of the separator assembly defines a portion of at least two walls of the outer housing.

An electric vacuum cleaning apparatus including an autonomous robotic vacuum cleaner that autonomously moves between surfaces to be cleaned and collects dust and a station fluidly connectable to the autonomous robotic vacuum cleaner. The autonomous robotic vacuum cleaner includes: a container body accumulating collected dust, the container body including: a bottom wall including a disposal port; and a disposal lid opening and closing the disposal port. The station unit includes: a dust transfer pipe connected to the disposal port; a secondary dust container accumulating dust; and a secondary electric blower that generates negative suction pressure in the dust transfer pipe via the secondary dust container. At least one irregularly shaped ventilation groove that causes air to flow below the dust within the container body by the negative pressure generated by the secondary electric blower is provided to the inner surface of the bottom wall of the container body.
