I have the 400 and the 700. The 400 is out in the garage, so I'll try to get a picture of it tomorrow, but there is the 700. I bought this brand new in the box off of ebay for $100.
I tried one when they were being sold--clumsy,klunky machines-like pushing a wheelbarrow full of bricks!If there is a vac that needs a power drive-the Z sure did!And you need a forklift if you were going to slep it up the stairs.And don't like the bagless design-wished they made a bagged model.
