If you have smooth flooring just open the door of the machine so you can grip the rim of the aperture - and pull! Most machines are on smooth skid-like feet and once they get started will move easily. Slipping a sheet of corrugated cardboard (flttened out box) under the feet will help the machine to slide.I can't see the inflatable things being any use other than to just lift something (and you have to lever whatever it is up a bit to get the unflated bag underneath first)
