A unique valve door mechanism is disclosed for use in a dual chambered utility type vacuum cleaner having two suction inlets whereby the inactive suction inlet may be selectively closed and sealed off from the atmosphere. The valve door is slidingly suspended between guide rails whereby the door may be selectively positioned adjacent the suction inlet to be disabled. Atmospheric pressure is utilized to urge the valve door against the selected inlet opening thereby sealing off the inlet from the atmosphere. The valve may also be in the form of a rotatable, elbow-shaped body having a single plenum. The body may be rotated between at least two positions where the outlet to the plenum is in fluid communication with a wet tank in one position and a dry tank in the other position.

The present invention teaches a utility, wet/dry, tank type, vacuum cleaner suitable for domestic use whereby wet or dry material may be alternately vacuumed. Two storage or receiving chambers are provided, preferably positioned one within the other. Two suction inlets, one communicating with the first chamber and the other communicating with the second chamber are provided such that wet and dry material may be selectively directed, by the user, to the appropriate chamber for collection.

Wet/dry utility vacuum cleaner

The present invention discloses and teaches means for effecting a vacuum seal between the cover lid, outer tank and inner tank of a dual tank utility type vacuum cleaner wherein the inner tank is telescopingly positioned within the outer tank and suspended therein from the peripheral rim of the outer tank. The peripheral rims of the cover lid, inner tank and outer tank cooperate to fluidly isolate the inner tank from the outer tank and seal both tanks from the atmosphere.

A floor care appliance or the like is provided with a hand grip having a switch retaining member that also serves as a portion of the means utilized for retention of a cord strain relief. The hand grip and handle on which it is mounted provide the remaining portions of the means for retention of the strain relief, while the handle also serves as a retaining means for the switch retaining member.
