would'nt be without one
I use it for rear windows on terraced houses where I must go through the house, so much quicker than unreeling and positioning hose and trip hazzard cones from the van, plus the customers front door can be closed whilst you clean the back saving their beloved moggy from making a dash for freedom out the front door and straight under the wheels of a tesco home delivery van, they like my thoughtfulness, god knows why but they do

plus a backpack is useful if you ever use detergents for grubby jobs or conny cleans. ditch the shoulder straps though, never bothered to try carrying one on my back
