This is a follow-up to the previous question as just because you know robot vacuums are not designed to clean water off the floor, does not mean it will not accidentally happen at some point. After all, humans are not perfect and you may not even realize if something spilled. If you notice that your companion vacuums up excess liquid, you need to take action right away. Obviously, the first task you need to do is to turn off the vacuum as quickly as you possibly can.
As you do not want the liquid to rest inside the device, removing all components as quickly as possible is your next step. This is going to include the main brush, dustbin and all the filters. After all components that can be removed are removed, allow all them to thoroughly dry. You could even take a cloth to dry off the inside of the vacuum. Once everything is dry, re-install the vacuum to working order. After which, if the vacuum is not operating properly, you may need to contact the manufacturer for assistance.
