My PowerMax
I don't know for sure when the PowerMax was intruduced, I think it may have been late 1991 or early 1992. When I visited Hoover in 1993; the burgundy PowerMax was one of the assembly lines they showed me in operation. It was cool seeing them assembled.
I've never found a burgundy one, but did snag the black TOL model when I was working at a Hoover store. Mine is dated July 1992. I've probablly had this since 2006. I completely rebuilt it, greased it, new fan, new brush strips, etc. I even put a new transmission on it. The brushroll housing and the duct that the hose plugs into, underneath the hood had broken. The parts were NLA when whoever brought it in to the Hoover store, so they opted to trash it and buy a new machine. I somehow managed to glue/tape the broken parts together and got years of use out of it. Last year sometime, I found a blue BOL machine as a doner and finally replaced the broken parts.
It's kind of a monster of a vacuum -- loud... but it does clean really well. The tools are sort of a joke... not really much suction or airflow. But I think they look nice on the machine. Certianly more useful IMHO than the "HelpMate" that was on the Concept II.
I usually run it at low/medium power. Only the high traffic areas at the high speed. Mine has the 4-brush Concept brushroll, but sometime in the middle of this run, I am pretty sure Hoover switched to an Elite-style brushroll.
The PowerDrive machine which followed from about 1994-1998 really was just a modified Elite. Nothing about it was Concept. Also good machines, certainly quieter. But not fun to disassemble and work on...
