I use it on both hard floor and carpet. What I like the most about this canister vacuum is the extreme compact size, light weight and the powerful motor. It is the most agile vacuum I ever use. I carry it up stair, down stair and any where in the house like nothing happen. I am also delighted by the extreme quiet motor and the center balanced handle. What I don`t like is the sharp edge of the handle, the whistling sound that come from the couple port of the flexible hose. The engineers worked so hard to subdue the noise of the motor but they missed the resonant frequency of a hollow. The whistling sound can be minimized by just increase the diameter a little bit. I also don`t like the wheel-less nozzle. The wheels should make the nozzle move faster and reduce friction and scratch. Above all, it is the greatest thing since the slice bread.
