I bought a Mosmatic 21" floater surface cleaner a few months back and ran into an immediate problem - - - it doesn't float. So, I called Mosmatic.
When the Swiss designed this unit (which has arguably the best swivel in the world) they designed it with a water recovery system in mind; hence, when it's on the ground it creates a vacuum instead of a cushion of water. Upon examing the skirt, it's solid - - no place for the water to go outward and create a water cushion.
I took a pair of tin snips (that nylon is really thick) and cut out three small sections on each of the opposing sides and it cured the problem.
