Model reviews

23 robot vacuums, 115 published figures, and a link to the page each one came from. Plus, on every model, the specifications its maker declines to publish.

These are specification sheets rather than hands-on reviews, and the distinction matters. We have not owned or handled any of these machines. What each page gives you is everything the manufacturer publishes, compiled in one place with a source on every row, plus a plain statement of who the machine suits and who should skip it.

The most useful thing on many of these pages is what is missing. Two of the six brands here publish no suction figure and no climb height for any model we cover, while marketing hardware aimed squarely at the problems those figures describe. Read the blanks alongside the numbers. How we pick explains why we leave them blank rather than filling them in.

Disclosure — some links on this page go to Amazon, and we earn a commission if you buy through them. It costs you nothing extra and it does not change what we recommend or in what order. The full disclosure.

Published climb heights across every model we cover

7 of 23 models publish this figure. Every number below links to the page it came from.

ModelStated max climb heightCondition and source
Roborock Qrevo CurvRoborock40mm (1.6in) double-layer, 30mm (1.2in) standardRoborock's own wording is that it can overcome standard thresholds up to 3cm and navigate double-layer thresholds up to 4cm. Stated maxima assume a clean square edge; a rounded or worn sill behaves differently.Source: Roborock Qrevo Curv product page — threshold crossing (retrieved 2026-09-01)

Dreame X50 UltraDreame60mm over a series of steps, 42mm over a single stepDreame's own condition, quoted: "The gap between steps should be greater than 4cm. For a single obstacle crossing and a single vertical step, the highest obstacle crossing height is 4.2cm." The 6cm headline therefore does not describe a single door sill.Source: Dreame X50 Ultra product page — ProLeap step climbing (retrieved 2026-09-01)

Homes with a dog and a real risk of an accident
