I am a left above the knee Amputee.I need a Vacuum that is easy to push,I have a Windtunnel self-propelled but it's not that easy to push and is LOUD.My Sharp twin energy which was very easy to push and also quite just died.I found me a Panasonic Performance Plus MC-V7367 and I bought it thinking it would be the same they look so much alike.The Panasonic is used but in great shape but it's not the easy to push even after new brush-roll and everything and that Tri-force motor does not seem more powerful and it is not as quite.I was thinking about getting a Carpet pro has anybody used one of these?I want a full size Vacuum that has my tools and I can push without it killing me.
