Ben M , i dont usually have a pop chap , but since you got your big vac you been full of it , what with your carbon poles and all that , you started out with a clarke and ally poles and it did the job , correct me if im wrong ?
I still use ally poles and a 1400w vac it works the same as yours but on occasion could take a little bit longer , i have vid footage as to what a 1400 can do , dont just slate it cos you have moved on , after all i bet it was the clarke that gave you the assets and the will power to spend bigger and move on and up
Dont take it the wrong way chief , just saying what i see !
