Blue Check Tank Troubleshooting
Normally, Scooba's blue “Check Tank” light
illuminates when Scooba’s Clean tank is empty.
If the Check Tank is lit and the Clean tank is
not empty, follow these steps to troubleshoot
the issue.
If the battery’s yellow tabs are not inside the guide holes in the battery
pocket, the tank and robot base may not be properly connected.
Use of only water or extremely small amounts of cleaning solution reduces
Scooba's ability to recognize water in the Clean tank. Always use the recommended
amount of cleaning solution and water.

one quart of water before filling the tank.

Fill Scooba's Clean tank with approximately 1 cup of cold water, shake vigorously, and empty it to
remove any debris in the tank. Refill Scooba's Clean tank with water and Clorox®Scooba cleaning
solution or vinegar. Use up to one full Scooba measuring cup of cleaning solution if the check
tank light remains on.
Confirm that the battery, filter, and vacuum port are properly
installed, and that the tank is completely closed.
