Verdict
Still the best obstacle dodger we've run (pet-waste guarantee), but the value math has caught up with it.
- Best-in-class obstacle avoidance
- Pet-waste avoidance guarantee
- Imprint multi-robot linking
- Small bin means frequent dock trips
- Price is hard to justify vs 2026 rivals
Best for: Homes with floor-level hazards (pet waste, socks, cables).
Skip it if: Anyone optimising for value in 2026.

Written reviews elsewhere
“The iRobot Roomba j9+ delivers reasonable performance overall in a household with multiple floor surfaces. It does a decent job on hard floors, leaving only a little fine material along wall edges and in corners.”
RTINGS“The iRobot Roomba j9+ is a user-friendly robot vacuum that justifies its high price with strong suction power, reliable obstacle avoidance, self-emptying functionality, and ample app features.”
