That's a very nice S3611 PowerMax Supreme canister that you have Martin187! That machine is circa 1994- 1998
The original picture in this post is a Google image from a Craigslist ad that I saw years ago and is still passing around Google. It's a small photo and hard to tell the exact model color of that unit. What I can tell you is it has the variable speed slide switch on the hose handle along with bare floor on/off and vacuum on/off. The tan hand hose of the color sets the machine to earlier than 1998. That was Hoover's worst hose material that they ever used on a canister vacuum. The black hose material that followed on later PowerMax and Futura canister was drastically better. The particular hose material on the one shown was known to crack, kink heavily, gain permanents bends easily and even tear easy.
PowwerMax canisters in general:
25' cord with rewind
12" dual row bristle brush agitator--- same brush roll as Hoover Elite uprights
low profile PowerMax branded power nozzle with headlight and usually with belt view window
4 piece on board tool set
Micro Filter under the dusting brush to help capture motor carbon
Covered tool storage
Plastic smooth tread on all wheels which wasn't great for traction
Excellent overall deep cleaning and carpet grooming.
Parts:
Hoover S bag
Hoover 38528-011 belt
Hoover 48414081 brush or 48414051 for prior to 1997.
Motors varied greatly over the years. Early 1991 era Hoover S bag canisters had a 10.5 amp system rating
Mid 90s were rated at 9.8 amps, like Martin's S3611 PowerMax Supreme
There was a 9.6 amp at one point
The last generation excluding Windtunnel were all 9.3 amp.
*** All Windtunnel S bag canisters were 12 amp and quieter than the 9.3 amp PowerMax units
I love PowerMax canisters and have had many over the years.
