Frequently asked questions
How long should the cleaning solution dwell before extraction?
Allow detergent to dwell on the carpet for 10 to 15 minutes before extracting. The dwell time lets the chemistry break the soil bond from the fiber, so the vacuum-and-rinse pass actually removes it rather than just relocating it.
What is the difference between 100 PSI and 300 PSI extractors?
A 100 PSI machine like the 66-2100 is gentler and faster to dry - good for routine maintenance and delicate fibers. A 300 or 500 PSI machine pushes solution deeper into the pile, which is what heavy traffic lanes, restoration projects and ground-in soil need. Same 12-gallon tanks and same footprint, just more pressure on tap.
Should I run hot water or cold water?
Hot water (160 to 200 degrees F) releases soils, oils and traffic film better than cold and helps the carpet dry faster. If you need built-in heat, step up to the 66-2100-H heater variant - otherwise pre-heat your fill water.
How much carpet can I clean per tank?
Coverage varies with soil load, but plan for roughly 1,500 to 2,500 square feet per 12-gallon fill before you need to dump the recovery tank and refill solution.
Is this safe on wool or other delicate carpet?
Yes - the lower 100 PSI pressure is gentler on natural fibers than higher-pressure extractors. Always test in an inconspicuous area first and use a wool-safe detergent.
