How this ranking is built
We rank models by how often owners mention battery / runtime in their comments. This list reflects real-world usage and satisfaction, not lab tests. Battery runtime affects how much of your home can be cleaned in one pass. Most models last 90-180 minutes. Larger homes may require the robot to return to the dock to recharge and resume. Check if the model supports resume-after-recharge.
