Interesting and really nice design.No rotating brush to snag or pull off the matteress buttons-guess could be used on ulphostered furniture as well.However----THE NOISE!!Sounds like you are trying to vacuum your matteress with a Sawzall!The thing sounds like it will saw your matteress in half.Would be so nice if the tool was quieter.
Oh yes--remember the modified Kirby "G" type vacuum that had the UV light fixture attached to it and sold for like $12,000 to vacuum matteresses with?Sort of surprized in a way that the attachment shown in the video didn't have a UV light on it.But kinda neat and clever.
