Abstract
Abstract A rotary flooring cleaner-polisher wherein a shroud overlies a plurality of floor contacting rotating wands. The operator is able to selectively supply fluid, a vacuum or both to the area beneath the shroud permitting both application and extraction within the defined area via a hollow central drive shaft. At least one of the rotating wands which are flexibly mounted to the drive shaft includes an elongated slot along its lower surface in communication with the vacuum source such that the extaction is done through the wand and then through the drive shaft. The solution to be applied to the flooring surface may be sprayed in a general pattern beneath the shroud or in a controlled manner through the interior of one or more of the wands.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A rotatable cleaning head for use in a carpet cleaner or the like comprising: a hub member including a quick release means for securement to a hollow drive shaft including means for conducting a negative pressure air flow and a means for conducting fluid under positive pressure; a plurality of radially outwardly extending resilient arms secured to the hub member and rotatable therewith; vacuum head means pivotably secured to each resilient arm member, said vacuum head means including a lower surface designed to be in contact with the surface to be cleaned and including a radially extending slot in fluid communication with the negative pressure airflow conducting means; nozzle means in communication with the positive fluid flow conducting means whereby fluid may be sprayed upon the surface to be treated, and the vacuum head means, always in total surface contact, agitate the surface and extract the fluid.
Claim 2
Dependent Claim
147 words
A rotatable cleaning head for use in a carpet cleaner or the like comprising: a hub member including a quick release means for securement to a hollow drive shaft including means for conducting a negative pressure air flow and a means for conducting fluid under positive pressure; a plurality of radially outwardly extending resilient arms secured to the hub member and rotatable therewith; vacuum head means pivotably secured to each resilient arm member, said vacuum head means including a lower surface designed to be in contact with the surface to be cleaned and including a radially extending slot in fluid communication with the negative pressure airflow conducting means; nozzle means in communication with the positive fluid flow conducting means whereby fluid may be sprayed upon the surface to be treated, and the vacuum head means, always in total surface contact, agitate the surface and extract the fluid.
Claim 3
Dependent Claim
120 words
A cleaning head for use in a carpet cleaning device or the like comprising: a hollow hub member adapted to be in communication with a vacuum source said hub member removably secured to a hollow vertical drive shaft; a plurality of radially extending resilient arm members secured to and rotatable with the hub member; a cleaning head pivotably secured to the outer end of as least a purality of the arm members, each said cleaning head being substantially hollow and including a downwardly facing opening including carpet contacting lips and an exit port in fluid communication with the hub member whereby the lips remain in contact with the carpet regardless of slight changes in the orientation of the hub member.
Claim 4
Dependent Claim
120 words
A cleaning head for use in a carpet cleaning device or the like comprising: a hollow hub member adapted to be in communication with a vacuum source said hub member removably secured to a hollow vertical drive shaft; a plurality of radially extending resilient arm members secured to and rotatable with the hub member; a cleaning head pivotably secured to the outer end of as least a purality of the arm members, each said cleaning head being substantially hollow and including a downwardly facing opening including carpet contacting lips and an exit port in fluid communication with the hub member whereby the lips remain in contact with the carpet regardless of slight changes in the orientation of the hub member.
Claim 5
Dependent Claim
120 words
A scrubbing device primarily for use with carpeting comprising: a downwardly open shroud means including an opening in the upper portion thereof; hollow vertical driveshaft means extending from a drive means mounted above the shroud means to selectively rotatable cleaning means beneath the shroud means, said cleaning means comprising a plurality of radially extending resilient arms secured to the hollow vertical driveshaft means and a plurality of pivotably mounted cleaning heads having downwardly facing openings to contact the surface providing the sole support for the scrubbing device, and exit openings in fluid communication with a vacuum source, whereby the device may be moved over the surface, the heads constantly agitate the surface, and foreign material be extracted through the openings.
