about 20% of my round is in small villages in Gloucestershire and Worcestershire (all around the border, near Tewkesbury)...places like Pendock, Berrow, Birtsmorton, Apperley,Forthampton,etc, etc. All get done with the pole,up and down, front and back, no matter what type of window they are. The trolley rarely comes out of the van, due to a 35 metre extension to the hose.No setting up, just park, take the pole off of the roof, switch the trolley on....and go...easy peasy....
