Patent number: 6687952Abstract: A vacuum cleaner attachment which can be connected to a dry vacuum cleaner to convert the dry vacuum cleaner into a wet vacuum cleaner such that a liquid can be removed from a surface. The vacuum cleaner has a vacuum source for drawing an air stream through an inlet and exhausting the air stream through an outlet. The attachment comprises a housing including a passageway having a first end and a second end in fluid connection with the first end, and a coupler on the first end for coupling the first end with either the inlet or the outlet of the vacuum cleaner so that the air stream produced by the vacuum source passes through the passageway. The housing also includes a reservoir and an intake nozzle.Type: GrantFiled: January 7, 2002Date of Patent: February 10, 2004Assignee: HMI Industries, Inc.Inventor: Traian Mohan, Jr.

Patent number: 6511531Abstract: An air filtering and freshening device comprising a filter element within the intake of the device housing, a motorized fan mounted within the device housing which draws contaminated air into the device, and forces air out of the device through an outlet having separate exhaust and scent discharge passages. The exhaust passage including a plurality of arcuate vanes radiating outwardly from the interior of the device, and being disposed across the exhaust passage to promote efficient operation by reducing the pressure drop through the passage and minimizing operational noise. The scent discharge passage includes a scent element producing a freshening scent. The scent element is removably positioned adjacent the scent discharge passage, which carries high velocity, high pressure filtered air from the motorized fan, picks up the concentrated freshening scent, and discharges in an effective and efficient manner, a continuous stream of freshening scent.Type: GrantFiled: January 26, 2001Date of Patent: January 28, 2003Assignee: HMI Industries, Inc.Inventor: Mark A.
