A particle receiving device for attachment to a particle outlet of a vacuum cleaner and/or of a cyclone separator and for receiving separated particles, including: a particle receiving volume for receiving the particles, an access element with an access element opening through which the particles can be transported into the particle receiving volume, and a closure element. The access element is selectively displaceable relative to the closure element into a closure position in which the closure element closes access opening, or into an open position in which the closure element releases the access element opening.

A handheld vacuum cleaner including a suction inlet, a main body, a handle defined by a portion of the main body, a motor disposed within the main body operating a suction source, and a filter coupled to the main body. The filter is configured to separate debris from a flow of fluid drawn through the suction inlet. The filter includes a housing forming a first volume and a filter media forming a second inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container configured to store debris separated by the filter media from the flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.

A handheld vacuum assembly for the capture and collection of small insects that includes a vacuum body defining a suction chamber, a motor operably configured to generate a vacuum downstream in the suction chamber, a funnel member defining a suction channel located downstream of the suction chamber and a suction channel area therein, a valve disposed within the suction channel that is configured to open and close to inhibit or prevent insects from leaving the funnel member, and a filter assembly disposed upstream of the suction channel, downstream of the motor, having a porous membrane member, having a filter cap selectively removably coupled to the porous membrane member and having a plurality of selectively removable strips disposed thereon and each having an adhesive surface oriented in a direction facing the distal tip of the funnel member.

A dust collection assembly includes a dust collection assembly main body configured to be removably provided in a base station main body and detachable from a front surface of the base station main body. The dust collection assembly main body has a dust collection cavity formed in the dust collection assembly main body and includes an engagement member provided at a side surface of the dust collection assembly main body. The engagement member is configured to be engaged with an engagement matching member of the base station main body and limited by the engagement matching member, allowing the dust collection assembly main body to be in communication with a dust suction pipe of the base station main body.

The invention relates to a vacuum-cleaning apparatus with a vacuum-cleaner unit and a filter bag, in which the filter bag is designed as a flat bag, as a nonwoven filter bag and as a disposable filter bag, and the vacuum-cleaner unit has a filter-bag-accommodating chamber with rigid walls, wherein the filter-bag-accommodating chamber has an opening which can be closed by a flap and has a predetermined opening surface area, through which the filter bag can be inserted into the filter-bag-accommodating chamber. The invention is distinguished in that the ratio between the surface area of a rectangle corresponding to the opening surface area and the surface area of the filter bag is greater than 0.70, preferably greater than 0.85, and highly preferably greater than 1.0.

A hand vacuum cleaner has an air flow path from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path and a non-cyclonic air treatment chamber is in the air flow path downstream from the dirty air inlet and upstream from the suction motor. The air treatment chamber has a front end having a chamber air inlet, a rear end having a chamber air outlet. A non-return valve flap closes an inlet port of the chamber air inlet. The non-return valve flap has an upper end that is mounted to the air treatment chamber and a lower end. The non-return valve flap is moveable from a closed position in which it closes the inlet port to an open position in which the lower end of the non-return valve flap rotates inwardly and upwardly whereby the inlet port is opened.

A robotic pool cleaning vacuum, includes a chassis, a suction duct topping the frame and opening into a filter bag placed above, and an impeller placed inside the duct to suck up debris via a suction port and push it into the filter bag, the chassis including a motor axle drawing the robot, the axle includes two drive wheels driven by a single motor, and an axis connecting the drive wheels transversely to the movement of the robot, the motor being configured to invert its direction of rotation in contact with a wall, the robot further includes a third free wheel for greater stability and maneuverability.

A dirt separator for a vacuum cleaner is provided, which includes a dirt separation chamber, a filter assembly, and an outlet chamber. The dirt separation chamber extends along a longitudinal axis from an opening to an outlet. The filter assembly extends parallel to the longitudinal axis and divides the dirt separation chamber into a dirt collection chamber upstream of the filter assembly. The outlet chamber is downstream of the filter assembly. The outlet chamber has a cross-sectional area that is substantially constant along a length of the filter assembly.
