I was looking for a quick way to vacuum the house and found this backpack amazing. It couldn't have been better for hard floors of all types, but while it picked up carpets well, it wasn't good at picking up pet hair. So I bought this nozzle for carpets and I am very satisfied. It does an impressive job and is very fast with a backpack. I couldn't be happier. The best advice. Do like the pros and use this device in very large office buildings.
