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: Obstacle Avoidance (Robot), Suction and Airflow
Cons: Storage footprint and upright-stand stability, Aesthetic design and finish
Runtime was a strength, with tested battery life supporting larger spaces and strong coverage before recharging.
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 was generally strong at about 40 minutes, but maximum performance mode could reduce usable time significantly.
Pros: Overall opinion, Solution / Liquid system
Cons: Weight, Steam Cleaning
Runtime was generally positive, with reviewers citing respectable battery life, one-charge cleaning of about 80 m², and longer use time.
Pros: Self-propel feature, Self-cleaning cycle
Cons: AI, Smart, App and Automation, Heating element
Runtime evidence was mixed but generally favorable: several praised long life, while high-power modes drained quickly and some tests fell short of claims.
Pros: Runtime, Suction and Airflow
Cons: Emptying and Mess Control, Suitability for heavy-duty use
Runtime was mixed: low or normal modes were often praised around an hour, while turbo/high-power runtime dropped sharply and one unboxing lacked charge.
Pros: Suction and Airflow, Overall opinion
Cons: Noise level, Storage footprint and upright-stand stability
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: reviewers praised long eco-mode claims or enough time for some house cleaning, but others found auto-mode runtime and whole-house use limiting.
Pros: Accessories and Tools, Suction and Airflow
Cons: Bin and Bag, Storage footprint and upright-stand stability
Runtime was usually considered adequate for small to medium spaces or full household sessions, though not exceptional versus newer or longer-running alternatives.
Pros: Overall opinion, Mopping performance
Cons: Controls and UI, Emptying and Mess Control
Runtime was context-dependent: several reviewers found it sufficient, while comparison reviews said 35 minutes lagged behind competitors.
Pros: Overall opinion, Under-Furniture Pickup
Cons: Price and Value, Controls and UI
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)
