Hi, my caster wheel drops out easiy from the groves… a bit like the groves are worn out already and are no longer able to hold the wheel metal spoke in place. I would like to know if this can be fixed without resorting to buying a new wheel? (Reduce, Reuse, Recycle) Please help?

Hi, I own a Braava 380. The issue with my unit is that barely 3 minutes after connecting with the Cube (blue light stays ON, not blinking, with the 3 front blue lights staying ON, not blinking), the ON/OFF button will blink RED, device will emit a few beeps and then the Braava will turn itself off. I have removed the debri in the wheels, cleaned the 2 front floor sensors, took off the cleaning pad, reapplied the pad properly, changed the C batteries in my Cube and fully charged my Braava. These steps did NOT solve the “Braava turned itself off” problem. Please help?
