One of the things that worries me about designs in vacuum cleaners, it's that most straight-suction canisters can't be upgraded to accept motorized powerheads. Among those that do, there are:
-residential canisters from Zelmer;
-commercial/industrial canisters from JohnnyVac;
-vintage Electrolux models with garbage-bin styled canisters;
-canisters from Fairfax
-some Numatic canisters
It's a shame that even the canisters with non-electric hoses from Miele and Sebo can't be upgraded to accept power nozzles. At Sears and at the Chapman boutique in Gatineau, I noticed that on the straight-suction Miele's, the female plug for the cord on electric hoses is either absent or there's some kind of covering that I don't know if it can be removed with a butter knife. The hose ports on the Sebo K2 models (with non-electric hoses) is just different from the ones that the K3 variants (with electric hoses) have.
If a person who lives in a home without carpets were to move to a house with carpets, one solution is that the person could get a lightweight upright (like a Riccar Supralite or a model from Oreck) or the Volt cordless powerhead. N0oxy stated in another thread that there's an option to get a powerhead for central vacuums with a standard connector and a cord with a female connector for the nozzle on one end and with a male NEMA plug (that's only in USA and Canada) on the other end. But this would only work on hose handles that accept 1 1/4" accessories and one might have to drill a hole on that hose and put in a C-clip button. Mike81 has found another way to upgrade a straight-suction canister to make it compatible with power nozzles.
I made an artwork of a straight-suction canister with a kind of feature that all of them in the future should have. What do you think of the concept? Oh! and you're all free to copy and print these artworks for future references.
