Vertex DuoClean PowerFins Upright Vacuum with Powered Lift-Away and Self-Cleaning Brushroll AZ2002/AZ2002C

i have an az2002 and the screws are all security torx screws on the power head. the soft brush doesnt spin anymore after about 2-3 years (if that) so getting it apart and servicing it is a nightmare.

Don't buy shark vacuum. I spent around 500$ for AZ2002 and used it only for 1.5 years. Its not meant for repairs. Ironically you could see the name of shark in top vaccum list in almost all reviews though.

I've had a shark vertex (corded) for ages and I have not been kind to it. 

After my second Dyson died I decided to try a Shark Vertex. Holy cow! The suction on this thing is scary good. Only complaint is that when I use the wand it wants to tip over.

Shark Vertex Pet. Two 30lb corgis and a 65lb Husky. I have had it for 4 years and it's handled all of it.
