I hate eureka now, I had a red one when I was little, 2006-2009 and I just got another from a thrift shop from 2005(identical to the older one I had and you have). Eureka kinda sucks now with only really airspeed models and copied Bissells
how come you didn't just buy the motor from the same model number? the motor you used was for 6583/6584 the motor it's supposed to have is a 6579-2. and why does it have the hose from the bissell powerforce helix turbo?
