The [Roomba j](https://www.amazon.com/s?k=Roomba+j&tag=wehavethat-20)7+ runs for about 75 minutes on a single charge. That covers roughly 1,200 square feet per cleaning session.

If the battery runs out mid-job, the robot automatically returns to its dock. It recharges and then resumes cleaning exactly where it left off.
