Top 5 Positive Customer Reviews for a 610
I bought a higher capacity and expected longer vacuuming out of my old Roomba 770. I feel like the battery performs comparably to the original one. If the vacuuming time is longer, you don't really feel the difference. E.g. if you were used to vacuuming 2 rooms in quick succession with the original battery, this battery will do exactly that, not the 3rd room however.
