Normally, I'd say my Lux Super J is my daily driver, but recently I've been using a Kenmore canister vacuum. I also discovered / rediscovered the power of the Dirt Devil 08100RT, which does not use the GS electric motor found in most versions. I always thought it was too loud, but I've been using it more in the past couple weeks.
Hopefully, starting in September, a blue Lux Model G will be my daily driver.
