Pretty neat! I paid over 2 grand for mine and that was over 30 years ago…150 bucks at harbor freight, some lumber, and tackstrip. Boss wasn't as excited as we were but he wasn't on the labor side. Cable is rated higher than winch so no worries about snapped lines. Crude but worked.
But I gotta say unless the carpet is really stuck the machine is a waste of time. If it’s coming up as easy as in the video it’s way quicker to just pull… Probably why your boss wasn’t so excited…
