Please could you give me some advice on which machine works best when used with prespray's.

Hi JMJ

There have been many references on the forum relating to the agitation of pre-treatment chemicals.

I think that you will find that most cleaners who use a mechanised system have a machine with contra-rotating brushes...there are various makes around including the 'old style' Host machine, Sebo do one and I am sure that other 'Cleanituppers' will come up with a few more..

Hope this helps
