Pre-spraying with or without scrubbing???

Option 2 is always going to give you better results. Better control of the solution is the reason.

If you were to employ the first option, the solution will simply penetrate down the shaft of fiber. There's no way to really control the solution that way.

It's much better to dispense the solution as you scrub the carpet immediately. So the first step is to speed across the carpet as you're lightly dispensing solution and scrubbing the carpet quickly. The next step is to double back over the carpet and perform a slow scrub over the carpet a second time. That will provide adequate dwell time, and it will enable you to control the solution much better than if you sprayed it on the carpet.

Thank you Rick for your detailed informations! Very helpful! I have a new big job and want to be very productiv. So it would be the fastest way to scrub and spray. Give then some dwell time and go over the carpet a second time with a microfiber pad. During dwell time i could scrub and spray another part of the office so i won't loose any time.

Do you have any advice how to adjust the spray jets so that i don't waste to much solution? Should i set them directly to spray on the floor or should i set them that the solution hits the carpet for example 15 - 20 cm in front of the machine?
