Inside every robot vacuum is a rechargeable lithium-ion battery that drains as the vacuum moves, sucks up dust, and spins brushes; when the battery gets low, it automatically returns to its dock to recharge.Why does runtime matter when choosing a robot vacuum for my home?

Runtime directly affects whether the vacuum will clean your entire home — if you have a large house and the vacuum only runs for 60 minutes, it might finish some rooms but run out of power before reaching others, forcing you to wait for a recharge.
