I love mine also,and have been using it more and more sence being a above knee amputee does make thing harder.The power of them suction at least is killer,I have always wondered about airflow.Like my Simplicity Synergy vs Windtunnel,im sure the Synergy has more airflow but having two motors in it makes it hard to judge.I do know the Hoover blows it away suction wise but the power is split. I love my Synergy but its heavy and the Hoovers self-propel system seems best design out there all though Dirt devil electric one worked pretty well on the one I used,Oh and I like Kirby but I didnt get the newer Eureka with one drive wheel.The Eurekas the older ones, most I have found are stripped, the gears.My Aunt got the Bagless one I warned her(I don't like bagless anything-No offence) but she thought the idea of not buying bags just wonderful.She kept it for 4 months then threw it away and bought one like ours.I have two of them a new one and a old one when they first came out and they still work great..I wonder what motor brand they use in them?You got a great Vac,but eurekaprince is right about that brush switch.I broke two of them,but its never broke if you lift it forward then switch it.You got a great buy....
