Les! It might be the motor but it can't be the brushroll as the Constellation is a straight suction canister! | ||

That's kind of wierd, he says it starts out shaking and then stops after a few seconds and doesn't shake anymore. Is something metal in there expanding as the machine warms up?I'm thinking it's temperature related because the cycle repeats when it cools down again,no? | ||

VacuumLad... How much did you have to sand on the bottom of your Connie? | ||

Does it sound any different when it is either shaking or not. I was thinking if it is related to it's warming up that it may be motor related. I'm stumped but curious. | ||

Did you try swapping the non-original hose with an original hose and seeing if that solves it too?
Do these have metal fans or plastic? If the metal fan is nicked, or if the plastic fan is warped/cracked, it can cause a wobble at low RPM but as it spins faster the wobble evens out because it's going so fast. Maybe even the motor bearings or old grease? Grease does smooth out and become more fluid as it heats up, maybe the grease has gone sticky? I know my old Kirby Classic has bad bearings and that thing shakes like crazy, all the way up to the handle. I've held onto it since 2009 hoping to fix it someday, hoping that will come this summer. I'd just make sure all screws are tight and don't keep backing themselves out of the holes, and also possibly run the motor by itself outside of the vacuum if possible, and see if you notice any wobble on the shaft or armature. The vacuum housing might just be acting as a carrier for the motor wobble if the motor is wobbly. The fact that the vacuum "floats on air" would make it more sensitive to being unbalanced, I am sure, since it has no wheels. | ||

What you're describing sounds like a sympathetic vibration. Basically, something vibrates a tiny bit, but at a very specific frequency it resonates with the rest of the machine and causes a massive vibration. In other words, your vac is vibrating ALL the time it's running, but to such a small degree, you can't notice. But as it reaches a very specific speed of rotation, it harmonizes and shakes a lot. Apparently, that particular speed only happens for a bit as it warms up. Naturally, changing the amount of air allowed to pass in or out will change the speed of the motor, and deharmonize the vibration.
Either which way, of course it's the motor, it's the only moving part. I'll second the dirty fan theory. It would make perfect sense. Clean the fan blade, try again. If not, there is a possibility that the bearings have some play in them. You can check for play by trying to wiggle the fan blade side to side. | ||

That might be doing it. My basement floor is the exact same thing. Poured concrete from approx. 1949/1950 and then glue down commercial carpet from approx. 1978. When they poured the floor, the guy smoothing it out must have had terrible eyesight. The floor dips and bowls all over, I only notice it now because the carpeting is getting older and losing its rigidity, so it is sinking into the dips in the floor.
I have a hell of a time running my Bissell shampooer across it, the plastic scraper part on the front keeps skipping across the carpet when I push it forward and it takes double the effort to shampoo. I have to move the shampooer a certain direction for every section of the basement so it doesn't skip, some areas I have to move it diagonally. | ||

If you know anybody, say a friend,relative or co- worker whose got an area that you could test your theory on, patio, smooth basement, carport or what ever maybe that would get you a fast answer! Somewhere with the perfect setting for Connie, if she acts up there, then... | ||
