Beam and Honeywell are the same. Honeywell being a re-badged Beam unit.

Warranty is a joke. Motor burns up, you're better off buying a motor from a third party, since the policy is "send the unit in for repair", and that costs more than just replacing the motor.

I've used AstroVac by Lindsay before, and had good luck with the line. Also used M&S AirVac and it was a good line. Used a lot of the Honeywell units, and while they are just a Beam in disguise, they did seem to do well. It's just that when something went wrong, I found myself up a creek.

Can't help with any info on the Vacuflow units, as I never used them.
