Understanding battery life and what actually matters for your home.
Here's a secret: battery runtime matters way less than you think.
Reality: Most homes get fully cleaned in under 90 minutes with efficient navigation. Manufacturers advertise max runtime in eco or quiet mode on hard floors — not in the mode or environment you'll actually use.
"180-minute battery life! Up to 3 hours of cleaning!"
Those numbers are measured in 'Quiet Mode' on bare floors with minimal suction. Real-world runtime is usually 30-40% less.
Bottom line: Claimed 90 minutes = ~60 minutes on mixed floors in normal mode. Claimed 180 minutes = ~120 minutes on mixed floors.
If the battery runs low mid-clean, the robot returns to dock, charges back to ~80%, then continues where it left off.
The catch: Total cleaning time increases significantly. That 90-minute clean becomes 2.5-3 hours when you factor in recharging.
