This is what i call my unger spin around! instead of a reach around! made this tonite as i was bored and it works fantastic! normaly you would reach for your applicator out of your boab, scrub window put your applicator back into your boab then use your squeegee to blade the glass! well i have tried this and it works really well just scrub glass spin and blade! futhermore as you can see from the pic i did not have to modify my unger boab as it fits perfect!
