If you are hard on vacuums you will wreck any suggestions given here unless you stop being an asshat to your vacuum. Stop kicking the shit out of your vacuum, yanking the cord out of the socket from 20 feet away and slamming the filter closed with the Wrath of Khan.

Or likely the issue is your previous vacuums were the $89 specials from Walmart as there are many BIFL plastic vacuums as long as you don't make it a habit of giving them the People's Elbow when the head gets wedged under the couch.

Riccar and Miele are the kings really and feature a lot of plastic, but they are NOT your $89 Walmart stick vac plastic. Your bigger failure points are we don't know your budget and floor type as those are the #1 and #2 metrics of purchase and we know neither.
