Purei9 turns to the dicking station every 15-20 min. (Much less than 90min.)
Also, it doesn't recommence cleaning after recharge.
Oops . I meant the docking station
Try to wipe the connections on both charger and robot with a cloth.
Also check that the battery symbol starts blinking when the robot has docked - it signals that it has got a connection to the charger.
I tried all above. Can’t get more than 25 min. Seams like a bum battery installed.
What color does the battery symbol have when it is returning to the docking station? If it is not red, it believes that the cleaning was done and will not continue cleaning once it is charged up.
Is it a Pure i9 that you have? In that case the runtime is up to 60 min in Eco and up to 40 min in full power. The runtime is also affected by carpets, rugs etc.
What kind of floors do you have? do you have carpet/rugs?
