Vacuums including a hollow wand and a vacuum accessory are provided herein. The vacuum accessory is configured to releasably couple with the hollow wand. A first terminal is disposed at a distal end of the hollow wand. A second terminal is disposed at a proximal end of the vacuum accessory. The second terminal is configured to correspondingly electrically mate with the first terminal. A biasing member is operably coupled to one of the first terminal and the second terminal, wherein, when the hollow wand is releasably coupled to the vacuum accessory, the biasing member is compressed such that the first terminal and the second terminal are maintained in mating contact with each other.

A filter assembly (100) and a cleaner having the same are provided. The filter assembly (100) includes a tank (1) and an air intake pipe (2). The tank (1) is configured to accommodate a liquid therein and has an air inlet (13) and an air outlet (14). The air intake pipe (2) is connected to the air inlet, has an air output end (22) located in the tank (1) and extending towards the liquid (A) or submerged in the liquid (A), and has a cross sectional area gradually increased along a fluid flow direction inside the air intake pipe (2).

The disclosed upright vacuum with telescoping head permits vacuuming beneath furniture and other home obstacles. The head of the vacuum extends from the body, allowing the slimmer head to slide beneath furniture without the bulkier body.

The head of the vacuum extends from the body using an extending section formed from two or more nested, telescoping suction tubes. The tubes are sealed to one-another using one or more gaskets. The telescoping tubes channel incoming air from the power head to the housing, where it is routed through a filtration mechanism.

The liquid filtration vacuum cleaner includes a vacuum nozzle head and a housing moveably coupled to the vacuum nozzle head. The vacuum cleaner further includes a liquid tank that includes a wall defining an interior volume and a tank intake channel positioned in the interior volume. The interior volume is configured to hold a liquid. The tank intake channel is positioned to direct debris received from an intake passageway into the liquid tank so that the liquid in the interior volume of the liquid tank filters the debris into the liquid so that clean air is exhausted. The vacuum cleaner further includes a separator configured to generate an airflow.

According to one embodiment, an upright liquid filtration vacuum cleaner includes a vacuum nozzle head and a housing moveably coupled to the vacuum nozzle head. The vacuum cleaner further includes a liquid tank that includes a wall defining an interior volume and a tank intake channel positioned in the interior volume. The interior volume is configured to hold a liquid. The tank intake channel is positioned to direct debris received from an intake passageway into the liquid tank so that the liquid in the interior volume of the liquid tank filters the debris into the liquid so that clean air is exhausted. The vacuum cleaner further includes a separator configured to generate an airflow. The vacuum cleaner is configured to seal the intake passageway when the vacuum cleaner is deactivated and further configured to unseal the intake passageway when the vacuum cleaner is activated.

A pet cleaning and treatment system has a variety of operating modes, including vacuum, washing, drying, dual vacuum and drying, misting, discharge, internal cleaning and refill and reset. Different modes may be selected and initiated by a user through a control interface which is in one embodiment an interactive interface on a touchscreen of a smartphone or a pad device, and in another embodiment a voice activated unit through which the user may select modes and control functions by voice commands. There is a hand-held application instrument connected by flexible tubings to supply heated water, vacuum and mist as needed.

A vacuum cleaner (100) comprises a suction head (120), a suction source operable to generate suction at the suction head (120) for collecting dust or debris from a surface, a liquid filter assembly (190), and a handle portion (140) adapted to enable a user to move the suction head (120) on the surface during normal vacuuming operation. The liquid filter assembly (190) comprises an air inlet (1906) for receiving dusted air coming in from the suction head (120), a filter reservoir (1902) for receiving a cleansing liquid such as an aqueous cleansing liquid to form a cleansing bath for filtering dusted air coming in from the suction head (120), and an air outlet (1908) through which air moving out of the filter reservoir (1902). The liquid filter assembly (190) is mounted on a filter receptacle (186) formed on a rigid housing portion which is intermediate between the handle portion (140) and the section head (120).

An antibacterial cleaning machine with wet filter includes a container body inside which are disposed at least one motor group for aspirating flows of air and debris from outside; at least one first tank for collecting the debris which contains a first volume of filtering liquid which is arranged along the passage path between the inlet and outlet; at least one internal path of the flows of air and debris that includes an inlet, an outlet, conveying means that have an inlet immersed in the filtering liquid. The tank includes at least one sanitizing element made of silver and/or silver alloy which is positioned immersed in the volume of filtering liquid.
