Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
It runs for 2.5 minutes approximately and then shuts off. I cleaned the filters and it still does it. What should I do?
Did you use it to vacuum up fine materials like powder? If you cleaned the filters, but they are original to the machine, replace them. Try changing the bag to a fresh one as well. Beyond that, check how freely the brush turns. If it doesn't turn freely that can but excess load on the motor, if its covered in threads, remove those.

This is telling you that there is poor air flow or a blockage somewhere. To simply check for proper suction, remove the accessory hose to see if there is normal suction, if not then your problem is further in the unit. Troubleshooting from there will tell you where the problem is. Another possibility is that your thermal overload circuit is faulty. in this case a pro vac shop needs to service the issue.

The only thing I can think of from your additional comments is when it warms up something expands and it loses continuity of the circuit. Most likely the switch or the breaker.
Another thing to check is if it has a hepa filter it may be clogged and is tripping the circuit. Try this. Remove the hepa filter, turn it on and let it run without vacuuming anything. If it continues to run past 10-12 minutes get a new filter.

You have lost air flow due to blockage. Look for blockage in the throat of the machine where dirt enters from the floor. Do this by removing the base plate or opening throat inspection flap if so equipped. Also detach the hose and drop a coin through to see if there is and obstruction in that area.
