Hi with  pure freedom trolley and gardiner hard sill brush with fan jets, what pressure should I be working at?

There is no set pressure, work at what you feel like.

This is a question we often see on this s forum. The real answer is put enough water on the glass to do the job. To little water will create problems as we flush the dirt of the glass.If the water is to little the dirt will not float off the glass and the particles will remain after  you are down. So put a lot of water and save come backs.That is the fact of the matter. Now shoot me down in flames but it is the truth of window cleaning. After the agitating of dirt on the glass rinsing is the most important part of a good clean so don`t save on water.Time is money so avoid having to go back or loosing the customer.

Wouldnt say you need loads of water, with my trolley I built I can get 4 terrace houses done with using under 25lts, never been back to complaints or anything!
