How to repair an electric outlet which died while running a carpet cleaner?
The breaker on the bottom right (with the green tab on it) looks tripped. They will move to center position without doing much else. Turn it all the way off and then all the way back on.
If that does not work: turn ALL your breakers all the way off and then all the way on to make sure all are reset. Then look for gfci receptacles and make sure to reset all you can find.
