Hey Derek:
It wasn't so much the bagless contraption as it was his insistence that it was "better" than the bag. Many people pointed out that it was a Eureka Optima dust cup and filter, mounted on a Kirby hose connector. We realized it restricted air flow even clean and empty, was a filthy mess to clean out, the filter clogged almost immediately, and it was a detriment to the way a Kirby, with its tremendous airflow, was able to clean the rug. He just didn't understand that he was making it worse and not better. And he liked to argue his points, in a group with many Kirby enthusiasts, who understand the Kirby way better than he did.
