Can only agree with the 5 stars for the battery. Enjoyed my Roomba now soon 3 years battery life was extremely fallen in recent months, until he sang his death song after only 20 minutes hard floor, ie red light. With the new battery he runs again, like the first day. The new battery has even 3300 mAh, which developed the original battery "only" 3000. "- Clear, just small difference, but trotzem nice to know I'm a dog owner with a Greater Swiss Mountain dog and let the Roomba again every day the whole lower floor suck (120 m² ) and everything is always spotlessly clean again and I do not need replenishment - supi and thank you !!!
