4 Things to Know About Robot Vacuum Battery Life vs. Runtime

Runtime is the actual cleaning time per charge Runtime measures how many minutes the vacuum runs before needing to recharge. Most models claim 90 to 180 minutes.

Battery life is the overall lifespan of the battery Battery life refers to how many charge cycles or years the battery lasts before degrading. Expect 300 to 500 cycles before noticeable capacity loss.

Runtime decreases as battery life declines After hundreds of cycles, the battery holds less charge, so runtime gradually shortens. You will need to replace the battery eventually.

Runtime matters for daily cleaning, battery life for long-term cost Focus on runtime when scheduling cleaning sessions. Battery life determines how often you will need to buy a replacement battery.
