I have a different plan. The local Sears outlet has a demo Elite Intuition canister that they cannot get rid of. Those have an eight foot long hose. The price is already reduced to $249. I told them if they would lower the price to $169 I will buy it. I'm waiting for the manager to chew on the offer a little. It has been sitting for a year unsold. At that price I can put a spare standard Kenmore Powermate on that wand (can't do that with the new Elite canister) and have a fine vacuum, plus I eventually want one for my collection anyway. We'll see if the store manager wants to make a deal.
I also have a Frankenvac project based on an old cream colored square Kenmore canister from the early 1980s that will be HEPA filtered (yep, that vac is surprisingly adaptable to modern filters), HEPA bagged (I'm using bags for Numatic vacs and there is a Riccar bag that also fits but has less capacity) and feature a big Lamb Advantek series motor for home central vacuums if I can figure out how to finagle one in there. It has plenty of room for it but coming up with a mount will be a challenge. I may just shove it into a tight fitting rubber sleeve and go with that. If that can't be made to work, my older 115923 will bolt right up to the existing mounts but I would rather go with the new motor with it's inducer fan. I have some ten foot hoses for these vacs (that was the normal length hose Sears sold back then) and Hayden Deluxe brush I use now. 501 air watts and 145 inches of sealed water lift through a ten foot hose ought to do the job. Only a small handful of modern vacs have that kind of suction going for them.
