In my opinion this is the best commercial canister vacuum cleaner. We have 2 of them and clean houses for rent. This is a very durable, well-built vacuum with extremely powerful suction. It sucks in everything that goes through the hose! The CO711 is not useless and has no unnecessary bells and whistles that break quickly. Its body is made of durable plastic, and there aren't many things to break or get caught on. The hose and wand are as good as you can expect. The level of sophistication isn't the same as a $$ Euro vacuum, but it's a solid commercial vacuum that's built to last. I doubt there is a perfect vacuum, but Clean Obsessed CO 711 comes very close.
