Introduction

If the tank in your iRobot Braava Jet 240 needs to be replaced, follow this guide.

After water is poured into the robot and passes through the filter, it is held in the tank. The tank is connected to the tubing and pump. This allows the robot to eject water from the nozzle onto the cleaning surface.

The tank might need to be removed, cleaned, and reinstalled if the robot is spraying dirty water. If the tank itself is damaged, it should be completely replaced.

Good guide. I would suggest doing steps 13-16 before step 12 and a small hook (bent wire, staple or the like) makes reattaching the spring (step 15) a lot easier. Otherwise, perfect.
