Question about Bosch BSA2222UC Compact Plus Bagged Canister Vacuum
OK, I plug in my vacuum, turn the dial half way between ECO and MAX and if i'm lucky, i get 5-6 minutes of suction before the machine totally quits. I wait 5 minutes, 10 minutes, 15 minutes before I hit the dial again and then sometime between 15 and 20 minutes I'm good to go again for another 5-6 minutes....
I took apart the vacuum, removed the circuit board and cleaned the tiny bits of dust off it carefully, removed the cord winder (without letting it unwind) and carefully replaced both parts, blew dust out of the 2 armature brushes (lifted out the motor, removed the insulation wrap from around it and the 2 rubber gaskets first), then re-wrapped the insulation, replaced the motor, put it all back together making sure the switch was aligned properly, and ran it without the filters, hose, etc, until I was convinced it would stay on without impedance, then added one filter, then another, then the bag, then the hose and lastly the floor head. It never shut off so I think that small amount of dust on the circuit board was the problem. Hope this helps.

Pull out the HEPA filter (or the charcoal filter) and you will see an intake port to the side of the main, circular fan intake (it will look like two small slits). Make sure that is unobstructed. If cleaning that doesn't help, remove the screws holding the plastic motor cover in place and remove this cover, pull the small circuit board that holds the on/off switch (very easily done), find the small copper sensing plate with a resistor attached to it and clean that off with some CRC Electronics cleaner. This small copper plate will sit just inside the aforementioned intake port when you reinsert the board. This fixed my shut off problem. Before you throw the whole vacuum away, run it without the HEPA filter if nothing else.
