Got this because my wife was about to do some indoor window cleaning. It seems sturdy and the recessed, threaded handle allows it to be used on tall windows fairly easily. The taller the window the smaller the angle between handle and cleaning pad. This is important in understanding a minor criticism. While the handle is designed to allow the user to pivot the pad from horizontal to vertical, there is also a tendency for the handle to pivot unintentionally when using it closer to one’s shoulder level. So my wife thinks that it would benefit from a way to lock and unlock the head at the pivot point so that it stays in better contact with the window at lower levels. But most importantly, it does seem to do a good job with less window cleaner and less effort than using paper towels or newspaper (the very old school way).
