Dual cleaning mode carpet extractor
First Claim
1. Carpet extractor for cleaning a carpeted surface comprising, in combination:
- a chassis movably supported on the carpeted surface;
a carpeted surface agitator carried by the chassis;
a clean solution tank for containing clean solution carried by the chassis;
a dirty solution tank carried by the chassis; and
means for picking up solution off the carpeted surface for collection in the dirty solution tank, with the clean solution being selectively dispensed upon the carpeted surface before the agitator in a first cleaning mode and being dispensed upon the agitator for introduction to the carpeted surface by the agitator in a second cleaning mode.

Abstract
A carpet extractor (10) operable in either a restorative cleaning mode or a maintenance cleaning mode includes a constant rate pump (96) which dispenses clean solution through a manually operated valve (98) to one of two lines (100, 102) having nozzles which restrict dispensing to high and low solution flow rates. In the preferred form, clean solution is dispensed at the high flow rate directly upon the carpeted surface and at the low rate upon the agitating brush (88). When restorative cleaning is desired, the valve (98) is manually moved to dispense at the high flow rate and a switch (110) is also manually moved resulting in the chassis (18) being propelled at a slow working speed. When maintenance cleaning is desired, the valve (98) is manually moved to dispense at the low flow rate and the switch (110) is also manually moved resulting in the chassis (18) being propelled at a fast working speed.
