Does a good in , nice and quiet. Good at hitting all the hard to get spots. Only complaint is it does clog with dog hair. We have a corgi and a lab, they shed a lot. It does a good job, but I feel the holes in which is sucks hair up into are too small.
Overall we are happy with the vac. We did not want a tank of water and cleaning fluid sitting on our wood floors so this is the perfect solution. We have 2 dogs that shed a lot and now that the vac is on a regular schedule it does a great job keeping hair out of sight. The vac sis get clogged up a few times during the first week due to dust and hair under furniture etc but that was expected. Would be 5 stars based on current performance however when we received the unit the vacuum head that holds the roller was jammed and I had to address which should not happen. I am very very pleased with canister capacity and the fact that we do not have bags to disppse of. Overall I definitely would recommend this vac for those with dogs.
