I update the firmware recently and today when I did a full vacuuming ( no mop) on the first floor I noticed the time had increased by 50%. My default suction power is set to Max.
Before FW update, it took 60 mins to clean 49 square meter. However, after I updated the firmware this week it took 93 mins to clean it. I also cleaned all the sensors as well.
Does anyone experience the same issue?
