I don't know about the flipper. The Wagtail combo has an aluminium body and a pad, like a paint pad and the blade. it works on the same principle as a Backflip all in one tool. The pad puts your solution on the glass and the blade follows it taking the solution off. It's very much lighter than the backflip.
The pad doesn't hold as much water as an applicator so you need to use it with a bucket on the belt, and unlike an applicator you need to fill this bucket.
I pour two mugs off solution in the bucket on the belt, and this allows me to do the entire inside window of a large pub/restaurant. Get one, you won't regret it. Dai
