roomba 560 got wet and now it doesnt go forward
at first i noticed a broken wheel, so i replaced it.
irobot local dealer says that when it gets wet the motherboard dies and isnt worth fixing (he wants me to buy a new one)
if its a motherboard problem, cant i just change the motherboard? or might it also be a sensor problem?
how do i make sure it is a motherboard issue and not senssor?
