A:Answer Yes it is return to base to charge. As long as the base is not obstructed it can return. If you have the mopping attachment in place and the charging base is on carpet you might run into some issues. If it runs out if water it will stop, make an alert, as long as it has battery it will just sit in place until the tank is refilled. If the bin is full of dust you will notice poor cleaning and should empty the bin every time it goes to charge or get the auto-empty charging station.
