Air-Way's new brush roller
The only new brush roller offered by CenTec is the current, chevron style. The beater-bar brush, with replaceable bristles, is only available as a repair part. For many rugs, the beater-bar brush is the way to go. However, for newer rugs with very long pile, the new chevron brush is really better.
Air-Way has done a splended job of keeping the machine up with the times. When I first became involved with them, back in 1999, the machine was still white in color (like an oxygen cart), it did NOT have direct connect at the handle or the power nozzle end, and it had the cheap Douglas power nozzle. I have a video tape that I made during my two visits to the factory. One of them shows the owner of Air-Way and myself fighting over the position of the two speed switch. I got my way, and the first Air-Way Signature Series models were, indeed, two speed machines. Ultimately, Air-Way decided that the extra manufacturing costs involved with the two speed models was not feasible and discontinued the two speed motor models (called "select-a-flow"). Those first two speed models are now collector's items.
