Hearthline is editorially independent. When you buy through links on this page we may earn a commission, which funds our testing. It never changes what we recommend or how we score. How we make money.
Standardised debris on hard floor, low pile and medium pile carpet, plus a particulate leakage test in a sealed chamber.
Every manufacturer quotes runtime on the lowest setting with a non-powered head. Our figures are on the floor head, on carpet, with a half-full bin.

Methodology
Every product here was tested in a working home against standardised tasks. Scores are the mean of five measured criteria and are never adjusted for commercial reasons. How we test · How we review.
The Home Brief
Several mornings a week. No filler, no fake urgency, unsubscribe in one click.
We ran both flagships through identical debris, carpet and filtration tests.
We ran nine robot vacuums through the same messy house. Obstacle avoidance, not suction, separates them.
Twelve months of daily use, measured pickup and honest runtime figures.
Some things need weekly attention. Most of what people scrub daily doesn't.
