Pet hair changes the robot-vacuum buying decision. The headline suction number matters less than brush design, hair detangling, navigation, bin size, self-emptying docks, obstacle handling, replacement parts, and whether the robot can clean under furniture without constant rescues.

For most homes, the right choice depends on the floor mix. Roborock and Dreame are strongest when buyers want premium mapping, mopping, and automated docks. iRobot Roomba remains attractive for people who value a familiar ecosystem and part availability. Eufy is the value route for simpler layouts, while Shark is worth checking when local retail bundles and easy returns matter.

This is a source-based buying guide, not a hands-on lab test. YNIX does not invent cleaning scores or live prices. Before buying, readers should verify the exact model generation, replacement brush cost, warranty, app support, return policy, and whether the dock size fits the home.
