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 surface cleaning apparatus has a housing defining at least part of a cyclone chamber and a pre-motor filter chamber. In one embodiment, the housing is pivotally mounted to the main body of a hand vacuum cleaner. The housing is moveable between an in use position and an emptying position, in which the cyclone chamber and the pre-motor filter are concurrently openable.

A separator unit includes a collecting container enclosed by a housing wall, extending along a longitudinal axis, and having an inlet opening disposed on the housing wall for a suction airflow. The separator unit is configured in such a manner that a suction airflow that is passing through the inlet opening into the collecting container has a flow direction running in the circumferential direction with regard to the longitudinal axis. The separator unit includes a diversion element which is positioned downstream along the flow direction and has a surface which acts on the suction airflow. The normal vector of an obliquely positioned section of the surface of the diversion element runs in an oblique manner with respect to the longitudinal axis. A suction apparatus having the separator unit is also provided.

A separating unit for a suction apparatus includes a collecting container surrounded by a housing wall extending along a longitudinal axis and having an inlet opening for a suction air flow. The separating unit causes the suction air flow entering through the inlet opening into the collecting container to have a flow direction in a circumferential direction relative to the longitudinal axis. An annular diversion element has a surface acting on the suction air flow entering into the collecting container. The surface of the diversion element, at least partially, runs helically along the inside of the housing wall around the longitudinal axis. The surface of the diversion element has a step with first and second edges mutually spaced apart along the longitudinal axis. The step of the surface runs at an angle relative to the longitudinal axis. A suction apparatus having the separating unit is also provided.

A handheld extraction cleaner system includes a wet cleaning head including a wet suction nozzle, a dry cleaning head including a dry suction nozzle. A handheld base includes a modular receiver configured to interchangeably couple to the wet cleaning head and the dry cleaning head. A suction source is configured to generate a suction air stream through the wet suction nozzle when the wet cleaning head is coupled to the modular receiver and through the dry suction nozzle when the dry cleaning head is coupled to the modular receiver. A fluid delivery system includes a fluid distributor configured to dispense a cleaning solution on a surface to be cleaned, where at least one of the handheld base and the dry cleaning head is configured to at least partially prevent the fluid delivery system from dispensing the cleaning solution when the dry cleaning head is coupled to the modular receiver.

The present disclosure includes a separating device in which trash, garbage, and air flow through a suction port. A vacuum suction device is provided at the outlet side of the separating device and generates a suction force so that trash, garbage, and air can be sucked through the suction port. Additionally, a passage portion connects the separating device and the vacuum suction device to each other. Further, a collection container is provided on the lower portion of the separating device, and a collection bag accommodates the trash. A bag fixing means is provided to fix the upper end of the collection bag, and a suction passage in communication with the inner upper portion of the collection container and the inner lower portion of the passage portion sucks in the air included in a flow space between the collection bag and the collection container.
