Applicant has created systems, methods, and apparatuses for controlling the power supply of a vacuum cleaner motor. The systems and apparatuses include pressure taps to detect a pressure differential within a vacuum cleaner, a float that adjusts depending on an amount of liquid stored, and a power switch that toggles based on the pressure differential created by the position of the float. Alternatively, the float can be replaced by an air chamber so that the pressure differential is created by liquid rising above the volume of air trapped in the chamber. The method can include interrupting the current supplied to an electrical circuit of a power switch based upon a pressure differential created within the vacuum. By controlling the power supply to a vacuum cleaner motor based on a pressure differential created by the amount of liquid stored within the vacuum cleaner, the vacuum cleaner can automatically disable the vacuum cleaner's motor as the vacuum approaches its maximum liquid capacity.

The present invention provides an accessory 20 for use with, and adaptable to be releasably connected to, a vacuum cleaner 1. The accessory 20 comprises a vacuum intake head 21 having a chamber 21a arranged such that when the accessory 20 is connected to the vacuum cleaner 1, the chamber 21a is in fluid communication with the vacuum cleaner 1 and adaptable to receive air and liquid from and around the surface to be cleaned. The accessory 20 further comprises a filtration device 40 adaptable to separate the liquid from the air such that substantially no liquid returns to the vacuum cleaner 1. The accessory 20 can be used with both portable and central vacuum cleaners 1.

A surface cleaning apparatus includes a recovery tank, a suction nozzle in fluid communication with the recovery tank, and a suction source in fluid communication with the suction nozzle and the recovery tank to generate a working air path to transport debris-containing fluid including air and liquid from the suction nozzle into the recovery tank. An air/liquid separator can be provided within the recovery tank for separating liquid from air in the debris-containing fluid.

Disclosed is a dust collector that includes a filter frame, a cartridge filter, and an end cap and a cover that are connected to the cartridge filter. The filter frame is provided with a center column. The cover is operative to rotate around the center column along and against a rotating direction. The cover is limited to rotate between a first angular position and a second angular position relative to the end cap. The end cap is provided with a plurality of clamping members. When the cover is located at the first angular position, the plurality of clamping members clamp the center column; when the cover is located at the second angular position, the plurality of clamping members do not clamp the center column. Rotating from the second to the first angular position, the cover pushes the plurality of clamping members towards the center column to clamp the center column.

The Auto Water Steam Away is a portable or non-portable, automatic, multifunctional device for steaming away Unwanted water and or non-hazardous liquids without the use of any drain system. The wet vacuum sucks up and stores the water and or non-hazardous liquids, the float switch on a submersible pump contained within the tank discharges water and or non-hazardous (to the air we breathe) liquids into an outer steamer and the steamer vaporizes water into the air. The Entire device is can be on wheels which can make it portable.

A lid system for a wet-dry vacuum includes a lid shaped to cover an open end of a container and having a vacuum opening therethrough, and a hatch that engages the lid to cover and seal the vacuum opening when in a closed position and disengages from the lid in an open position to uncover the vacuum opening. A vacuum generator is mounted on the hatch, and a flanged filter is mounted on the lid and extends through the vacuum opening such that the flange supports the filter on the lid. When the hatch is in the closed position, the hatch compresses the flange against the lid to form an airtight seal between with the upper surface of the lid, and the vacuum generator communicates with the interior of the container. When the hatch is in the open position, the filter is insertable into and removable from the vacuum opening.

A vacuum that couples to storage units is provided. The vacuum includes a motor, an internal compartment, and an inlet and outlet that provide fluid communication between the internal compartment and an exterior of the vacuum. The vacuum includes one or more mechanisms to protect internal components from water damage and to prevent debris from escaping the internal compartment when the vacuum is being transported.

Disclosed is a dust collector that includes a filter frame, a cartridge filter, an end cap, and a cover. The filter frame is provided with a center column. The end cap is provided with a bottom plate, a plurality of sliding slots, a plurality of first side walls, a plurality of baffles extending from the first side walls, and a plurality of clamping members. The cover is provided with a plurality of protruding members and a plurality of extending members. The protruding members are operative to rotate along with the cover along the sliding slots. The filter frame includes an accommodating space configured for accommodating the filter frame. The bottom plate is provided with a plurality of through openings that run through the bottom plate. The through openings are disposed opposite to the baffles and are configured to communicate between the sliding slots and the accommodating space. The extending members extend into the through openings. The bottom plate and baffles are spaced apart. The first side walls are connected between the bottom plate and the baffles. The clamping members respectively extend out from the corresponding first side walls and are provided with ribs. An outer peripheral surface of the center column is provided with a thread. As the cover rotates along a rotating direction relative to the end cap, the cover is operative to push the plurality of clamping members to move towards the center column, allowing the clamping members to clamp the center column and the ribs to be embedded into the thread of the center column.

An accessory for use with a vacuum cleaner, the accessory being adaptable to releasably connect to the vacuum cleaner, the accessory comprising: a vacuum intake head having a chamber arranged such that when the accessory is connected to the vacuum cleaner, the chamber is in fluid communication with the vacuum cleaner and adaptable to receive air and liquid from and around the surface to be cleaned; and filtration means adaptable to separate the liquid from the air such that substantially no liquid returns to the vacuum cleaner the accessory further comprising spraying means for spraying a work fluid onto a surface to be cleaned wherein the vacuum intake head comprises at least one rotatable brush for agitating the surface to be cleaned, wherein the spraying means is adaptable to spray work fluid onto and around the at least one rotatable brush the accessory having a control means.
