Pure i9 error code 20: is it the batteries or the charging station?
My robot vacuum Electrolux Pure i9 has been working fine for 5 years, but a few days ago it reported an Error code 20, which should mean that it is the wrong charging station.
It is the exact same charging station as always, so I am wondering if it might be the batteries instead?
(I don't want to spend money on unnecessary purchases).
