I bought a commercial model because our abandoned carpets have been suffering for over 40 years from pets, children, basement flooding, septic residue, what more can I say. We cannot afford to replace the carpets upstairs at the moment. This vacuum cleaner removes dirt and pet hair from the carpet. You will see the difference immediately! This is not my first Oreck and I will buy another one if the need arises. Replacing the 40-foot cord with a compatible shorter cord can reduce the overall weight of the device once it starts to fill up. I am over 70 years old and can still use this vacuum cleaner until I fill the garbage bag to max capacity. This also results in cleaner carpets. I'd rather swap bags more often than give up clean carpets. During the current pandemic we cannot allow strangers to enter our home. Passengers include a resident with rheumatoid arthritis and two elderly people over 65.
