How This Was Tested
Each robot vacuum was carried between floors daily for two weeks. We tested multi-floor map accuracy, re-localisation speed after being moved, cleaning consistency across different flooring types per floor, and how well each app handles switching between floor plans.
Frequently Asked Questions
No. You carry the robot between floors and it recognises the new level automatically. The dock stays on your main floor. You just need to manually empty the onboard dustbin when cleaning other levels.
Modern robots use LiDAR to scan the room layout, then match it against stored floor maps. The best models like the Roborock S8 MaxV Ultra recognise the floor within 5 seconds of being placed down.
No robot vacuum can climb stairs. They use cliff sensors to avoid falling. For stairs, you still need a cordless stick vacuum or handheld. The robots handle everything on each individual level.
