Robovac L70 Error 4

Hey everyone! Just got a L70 hybrid and super excited about it! But the passed few days it keeps giving me an error 4. I take out the center roller and make sure there isn’t anything obstructing it, but every 5-10 minutes it comes up with that error. Could the motor or something be bad? Any help is appreciated!

Try a reset by removing the battery and insert it again after 30 sec.
