[USER=1113]@electromatik[/USER] I have particle tested their canisters. Machines that are not of the tandem Air Design blow a perfect zero.
The full size machine is discontinued. Which is very sad they also discontinued the more modern mid-size machines like the Riccar pristine.
I would stay away from the Wonder for a few years till they work out there bugs just like you never buy a car the first model year when it comes out.
I would also say for your money you'll get more from the German manufacturers. (SEBO and Miele)
I would say their uprights are pretty solid in comparison.
