I love mine. If you are a clean freak like I am then you will really appreciate it. For example, the kids spilled cereal all over their bed. It would have taken me forever to pick all those little pieces up with my hands. Enter the Dirt Devil. Clean in 60 seconds or less. Furthermore, sweeping the floors just can't quite get all that fine dirt out of the nooks and crannies, the vacuum does. The faster you can clean up messes the longer your upholstery and carpet will last. Just my 2 cents
I have the 342 and ours is installed in the storage compartment with the hose outlet being at the bottom of the stairs. How much do they charge to install?
