Vacuum cleaner turned on by itself.
Disconnect the low voltage wires from the side of the unit.
It was about 5 seconds we were staring at each other and i found it really unsettling so i turned back and looked again but she wasn t there.
If you can hear power going into the motor but the vacuum is still not working then turn the vacuum off and clean or untangle the brush head.
Once you have done so turn the vacuum back on and see if the problem is fixed.
I turned back and she was looking me right into my eyes.
For proper operation be sure the unit on off switch is always in the off position.
Be sure the vacuum unit is unplugged.
This happened last week and i m getting deja vu like i ve seen her before.
I bumped into her.

A central vacuum cleaner system that starts to run on its own has a problem with its control system.
If that roller is tangled and will not spin that could be a reason why the vacuum cleaner will not turn on.

An intermittent short in the low voltage control wiring is rare but it can happen.
If the vacuum turns off on its own select next step below to go through some troubleshooting steps.
