Yesterday, i was at thecraftcave’s house, and brought a few roombas, they were: ProGo, and Loudo. ProGo ran a successful complete cycle, while loudo behaved weird. After running for a few minutes, he started doing this: Start then stop, start again, then i pressed the power button to turn him off, then he turned back on again, i pushed the power button once more, and he finally turned completely off. Then after that, i took the battery out so he couldn’t turn back on again… So, i am yet to find the cause of it, and fix it. Contact me if this problem happens to you.
