I have a Harmony vacuum that's a couple years old. I recently sucked a fair amount of dog hair into it and was unaware something was amiss since the things so quiet. It just shut down and wouldn't come...
Nope, I don't think you torched the motor. I believe this model has a thermal cut-out on the motor that prevents this. I am pretty sure that the vacuum is blocked somewhere, you see, the air that is sucked in is the same air that cools the motor. When the vacuum is blocked, the cooling stops, motor overheats and the thermal trip jumps in. Ten mins later, the trip kicks out (as the motor cools) and away you go, but until the blockage is cleared it will keep doing this. The blockage could be anywhere right up to the turbine on the motor itself so, unplug it, get the screwdriver out and get going. Start with all external hoses\channels before tackling internals using a long piece of dowel or similar poking thingy.
One final note, you may well find that the pet hair managed to block the system by getting stuck on some other object that was already there (usually something silly like a toothpick) pet hair doesn't usually block vacuums on its own. Make sure you clear everything out or the problem will re-occur.
Hope this helps.
