Yep, okay on large panes of glass but a bit too big for little windows. I use my wide extreme only on really old houses with lots of large panes of glass and very few small windows but always on commercial work with plain windows or large panes as it saves a small percentage of time as my brush is fitted with two pencil jets and two fan jets on the outside so I turn the water flow up about half as much as normal work, enabling me to work quicker.
