This is a very versitile vacuum that cleans carpets like none other. This multi-cyclonic upright vacuum this vacuum has a lift off pod with dual motors one to control the brush bar and then a suction motor located inside the lift off pod. This was the first liftoff vacuum Bissell created and they now have other lift off vacuums that are new and improved and yet this one still last the longest. I would definitely recommend this for comercial uses along with resedential use. Maneuverability This vacuum is very easy to use and it's tools make it no problem to get into tight spaces. Ease of Maintenance The only maintance that is needed to keep this vacuum running is after every use empty the dust bin and then ounce a month rinse out the filters. Suction Performance This vacuum has better suction than many other vacuums. Versatility The lift off pod makes this vacuum one of the most versitile vacuums I have ever used. It comes with three tools that make all of your above floor cleaning mutch easier than traditional upright vacuums. The only down side to the lift off pod is that only one of the tools store on the lift off pod so you have to go back to the upright unit to get the tools you need. The power nozel makes cleaning pet hair off furniture and stairs easier than ever.
