No agitation? How do you wash your hair and hands?

[robert meldrum]

Dumb comment !

The action of the solution being fired at between two and five hundred psi is clearly aggitation and the action of rapid air movement due to the high vacuumation also aggitates.

Before either of these the wetting agent's surface tension breaking action has released the soil from the fabrics. However if you feel the need to add physical aggitation that's your choice.

It's simply not essential every time.

I certainly don't agitate berbers and certain loop piles.... Still do a cracking job, I just leave the pre-spray longer to dwell.

The CRB comes into it's own at bringing a carpet pile back to life...

It is not only the lifting of the pile,  the amount of grit and sand that you get out of the carpet is considerable and something that cannot be achieved by a rotary. If anything the flattening og the pile will inhibit the extraction of this crud.
Even people with truckmounts realise the importance of agitation as it will dissapate the prespray to all surfaces of the fibre.
I have had so many people say to me their machine is that powerful they do not need to agitate but once they have worked side by side with me to compare results they quickly become converted. There is a good reason for manufactures being able to sell their wares at the prices they do.
Kid yourself if you wish but the investment in a good machine for aggitation makes a big difference to the result.

Hardly a dumb comment.. Even a gentle brush on a Berber to a crb on a minger will spread the cleaner over the thousands of fibres and give a better clean.
