Eufy Robovac 11 Stops Randomly On Carpet

Explanation of away feature on the eufy 2c with homebase cameras mean,as the the information in the instructions does not give enough information.

So, I’m late to the party. My efuy 11s will run for about 2-3 minutes and stop. Its on wood floors, not on carpet. I’ve changed the battery, made sure it is fully charged and will continue to stop after about 2-3 minutes. I too can hit the power button and it will run again for about 2-3 minutes. Its an older unit, but why would that happen?
Thanks!
