Clean Base Seal Mystery Solved! (You'll Be Amazed)

I've run it every single day about 20 times and not a single error communicating with the clean base. The cleaning i did was more than just spraying underneath the bumper with an air can, i. Is the little square filter on the robot's dust bin clogged? Take it out and flip it around to check, or just replace. Make sure the lid is firmly closed and sealed.

I have a roomba i6 that says there is a sealing problem with the base. I tried eything from irobots sight to no avail. What should be the next thing other than calling them.
