This model is quieter and seems to have better suction than our older UV795 Shark model. It is also a bit lighter. But it does have some short fails in comparison. The electric cord is shorter and the plug tends to fall out of the wall socket. Poor placement of the on/off switch. It tends to suck up area rugs, they get stuck so you have to turn it off to fix it.  Crevasse tool doesn't have a brush like our UV795 Shark did.
