L50 Ultra Spot Cleaning

Our L50 Ultra has stopped mopping while spot cleaning. It used to mop and vac but now only vacuums.
Anyone experience this and find a consistent fix?

Is your custom cleaning mode set to vac & mop when you're attempting to spot clean? I believe when you spot clean, it just performs whatever custom mode you did last with your robot. So if that mode was vacuum only, it is going to spot clean doing vacuum only.
