I picked up my robot mid clean and removed a pine needle from the bin and when I restarted it it said suction motor failure. I watched a you tube video and realized it was going to require a full tear down and I did not want to do that! Thank you for the advice to drop it a few times!!! I put down a yoga mat and dropped her to the ground a few times and VOILÀ! It actually worked after I dropped her top down after I tried wheels down first. THANK YOU.
