I had a customer today tell me that i had squirted water through her window`s and halfway across her living room carpet,they were oldish window`s but were in good condition.These window`s come up spotless and she has never complained before,she went on to say that she wanted me to all the window`s trad way from now on after calling my WFP a jet washer.Since using WFP on this house it has shaved 20mins off the time and i think the cleaning lady has told her this,it`s a reasonable payer but quiet dodgy in places on york stone,since going WFP i`ve noticed some of these cleaning ladies getting a bit jealous about the time saving.
