Filter Queen & Aerus suction power....
Fred, take my word on it....the Filter Queen DOES NOT have more power than an Aerus-Electrolux canister, whether new or old. I have 2 brown Canadian Filter Queen Model 700 canisters, & a Filter Queen Limited Edition canister from the late 1990's, the last model to use the Ametek double-stage motor & old-style powerhead. Any of my Electrolux canisters, my 86, 89, AP280, 2100 & Grand Marquise, will easily pull 80" waterlift, same as the Filter Queen's. Plus, one HUGE flaw of the Filter Queen is it's filter cone....it clogs with fine dust way too easily & robs the vacuum of it's airflow quickly with hardly any dirt in the container. The fine dust gets attracted to the cone like a magnet! If you use an Electrolux canister with the HEPA cloth bags, it will clean much better than a Filter Queen & it's power will last much longer too.
