The valve (50) is disposed in at least one of the plurality of suction pipes (40). The sensor (80) acquires object information regarding an object in the environment. The controller (90) controls each unit. In addition, the controller (90) controls the valve (50) on the basis of the acquired object information.

An attachment for cleaning a socket is provided including a body with an insertion section of the body for insertion into the socket along an insertion direction and with a connection section of the body for connection to a suction inlet of a vacuum cleaner, the attachment including at least one cleaning element for mechanical cleaning of an inner surface of the socket. The attachment includes at least one bearing element attached to the body, wherein the cleaning element is rotatably mounted on the bearing element relative to the body about an axis of rotation aligned along the insertion direction, and at least one drive element attached to the body for automatically rotating the at least one cleaning element about the axis of rotation. A method for cleaning a socket with the attachment is also provided.

A non-marring nozzle attachment that may be used with a vacuum device to clean delicate surfaces such as lint screens. The non-marring nozzle attachment may use a non-marring material with a beveled surface to allow for a vacuum to safely and effectively clean delicate surfaces. The non-marring nozzle attachment may further include spaced slits to allow for more intimate contact between the nozzle tip and a surface to be cleaned. The vacuum device may be mounted near the desired area of use to a variety of rigid surfaces without having to penetrate the rigid surface with nails or screws.

A dust collecting pile includes: a pile base provided with a dust inlet in a top surface of the pile base; a pile body disposed on the pile base, and including a fan cavity and a dust bin; a fan disposed in the fan cavity and configured to form a negative pressure in the dust bin; and a bag support disposed in the dust bin, where a dust outlet port is provided in a sidewall of the bag support, and the dust outlet port is in connection with the dust inlet through a dust channel, where the bag support further includes a sliding baffle slidably provided on the sidewall and configured to be switchable between a first position and a second position, and the sliding baffle is configured to cover the dust outlet port in response to being in the first position and expose the dust outlet port in response to being in the second position.

The non-marring nozzle attachment may use a non-marring material with a beveled surface to allow for a vacuum to safely and effectively clean delicate surfaces. The non-marring nozzle attachment may further include spaced slits to allow for more intimate contact between the nozzle tip and a surface to be cleaned. The vacuum device may be mounted near the desired area of use to a variety of rigid surfaces without having to penetrate the rigid surface with nails or screws.

A dust collecting attachment includes a dust suction portion and a main body. The main body has a dust collection passage communicated with the dust suction portion. The dust suction portion has a negative pressure by exerting a suction force to the dust collection passage from a hose. The dust suction portion includes an inner pipe through which a tip tool passes, a first dust suction flow passage, and a second dust suction flow passage. The first dust suction flow passage opens a first suction opening to a side of a workpiece in an outside in a radial direction of the inner pipe and is communicated with the dust collection passage. The second dust suction flow passage opens a second suction opening to an opposite side of the workpiece in the outside in the radial direction of the inner pipe and is communicated with the dust collection passage.

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 including a cleaning head having a body to sit adjacent a first surface to be cleaned; and a head formation releasably connectable to a connection portion of the body; wherein in a first configuration the head formation is connected to the body such that the head formation sits adjacent the first surface or a second surface to be cleaned, and the cleaning head defines a first footprint, and in a second configuration the head formation is detached from the body and the cleaning head defines a second footprint.

Method and apparatus for cleaning an interior volume of an electrical component are provided. The apparatus includes a housing with vacuum pins extending from apertures in the housing. The vacuum pins are arranged and sized to fit through ventilation holes in a chassis of the electrical component. The vacuum pins are individually retractable so that a vacuum pin that encounters a structure in the interior volume of the electrical component does not impede remaining vacuum pins from further entering the volume. A vacuum source is attachable to the housing and applies a vacuum to the interior volume through the vacuum pins.

A vacuum apparatus with a magnetic and coarse material uptake surface primer for separating magnetic materials, non-magnetic coarse materials, and fine materials includes an intake housing having a magnetic element, a coarse material guide, a coarse material uptake portal and a fine material intake. The coarse material uptake portal is positioned between the magnetic element and the fine material intake. A storage chamber for holding the non-magnetic coarse materials is included, along with a release mechanism positioned such that the magnetic element adheres the magnetic materials to the release mechanism, and moving the release mechanism away from the magnetic element permits the magnetic materials to separate from the magnetic element.
