I used to like these until...
I used to think these were the same as the automatic machines, just without the feature and optional cordwinder. Once I used one and heard how noisy it was, and also wasn’t as easy to pick up with only the front handle and now hearing that the motors in these were indeed not as good...I think spending the money on a decent used automatic control model would make for a better investment on the dollar and provide you with an upgrade in quality at the same time. You can get a 1205, Golden Jubilee, Silverado, Olympia One, Diamond Jubilee, Marquis, Or Ultralux complete with a hose power nozzle and even the other attachments for $100 to $300 on eBay. Since the motor is shot on yours and the sled base is broken and the wheel is needed as well, it’s pretty much not worth the cost needed to fix it up versus buying a better used model.
Chances are if the sled base is cracked where it dips in for the wheel, it has pushed in some and split the bag compartment. That happened to my Silverado and I could not get full suction. I did replace the bag compartment with one from another Silverado I had who’s motor died and that resolved the suction issue. I always wondered why I was getting a line of carbon dust on the outside of my bag...there was a hairline crack right along one of the inner ridges that’s would open wider when the vacuum was running allowing a recirculation of air reducing the suction power.
