In-depth review
What it's like to own
The 11S MAX has been one of Amazon's best-selling robots for years because it's slim, quiet and simple. At 2.85 in it's the thinnest robot we list, so it cleans under beds and sofas most others can't reach.
It navigates in a random pattern, boosts suction on carpet automatically and climbs thresholds up to 18 mm. There's no app or Wi-Fi: you use the remote or the buttons, including scheduling.
Suction is the weak spot. eufy has long rated it at 2,000 Pa — far below the budget LiDAR robots — and its bristle roller isn't anti-tangle. With 59,000+ ratings it's proven, but some of those reviews are for other eufy models.
