Have jsut won a great contract. Well May be, as it took the previous one man band 3 months to clean the Development and I need it done in 2.5 weeks max. One final challenge will be the high interior gym window and autruim and a numpty high interior dome window 25 foot high. Previously have always done interior windows off a ladder or polle. Can any one better that as I can't use a ladder. Remember some time ago seeing a dragon fly inteiror window cleaning kit. Anyone have experience of it? Thanks Guys and Gals.
