Samsung SR 8855 Navibot, what is wrong with it?/Missä vika?

Our Navibot robot vacuum cleaner just spinning around. Cleaned all lenses and took hair and dust away from wheels and brushes, but it still works very odd. What can I do to repair it? Filmed with Samsung S10. Nr.1069.
Robotti-imurimme alkoi pyöriä ympyrää jokin aika sitten. Putsasin renkaat ja harjat pölystä ja hiuksista sekä avasin imurin, jotta pääsin puhdistamaan anturit ja suojakopan linssit. Ei auttanut, laite pyörii edelleen ympyrää lattialla. Pystyykö kukaan auttamaan?

I have cleaned those yesterday. Still just going around in circles.

Get your multimeter out and start testing :)

Can you tell, what I must test?

@@VeliMattiRautio Hi tell me the model and manufacture, I will look for the schematic . I would look over the pcb for dead components, probably multilayer capacitor that has cracked, look for tracked ones you will need (they will show as shorted on your meter) hope this helps

@@zzkjbry It is Samsung SR8858 Novibot. I think that cleaner think, that it is allways in corner and spinning around again and again and again?
