Runtime was consistently praised, with evidence for stellar battery life, full-home cleaning, no recharge, and larger-than-average battery capacity.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Cons: Price and Value, Storage footprint and upright-stand stability
Runtime was consistently strong enough for most homes and even large cleaning jobs.

Pros: Overall opinion, Mopping performance
Cons: Noise level, Dock noise
Runtime is well suited to larger homes and single-run coverage.
Pros: Obstacle Avoidance (Robot), Suction and Airflow
Cons: Price and Value
Runtime was strong in one review that projected 150 to 200 m² of coverage per pass.
Pros: Overall opinion, Mopping performance
Cons: Obstacle Avoidance (Robot), Mop lifting system
Runtime evidence was mostly good with above-average coverage and praised battery life, offset by one battery-strength caveat.
Pros: Mopping performance, Overall opinion
Runtime was mixed: some reviewers saw strong real-world runtime, while Vacuum Wars found below-average coverage per charge.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Cons: Map and Path Efficiency (Robot Vacuums), Heating element
Runtime ranges from very good whole-home endurance to below-average square-foot coverage, so large-home results depend heavily on settings and cleaning mode.
Pros: Overall opinion, Mopping performance
Cons: Value-for-money, Price and Value
Runtime evidence was mixed to weak: several reviewers reported fast drain or interrupted large cleans, while a few found it adequate for average spaces.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Runtime, Bin and Bag
Runtime was a drawback in TechRadar’s home test, where the reviewer got about 90 minutes and wanted more from a premium robot.
Pros: Adaptive chassis lift, Obstacle Avoidance (Robot)
Cons: Price and Value, Edge and Baseboard Cleaning (Hard Floors)
