I am thrilled by this completely cordless vacuum. It sucks really good. Since we have a lot of tiles and a few carpets and no room with carpeted floors, the battery lasts 3 to 4 days. Since we live on 2 floors, I drag him now sometimes with high in the upper room. The only thing that bothers is something that you can not get away with it under cabinets. But finally, the battery needs to go somewhere anywhere. Something "shrinkage" is always.
