Owner reviews
A top-tier robot vacuum we recommend without hesitation
In our independent assessment, the iRobot Roomba j9+ Combo earns 86/100 — an excellent robot vacuum.
Its strongest area is navigation (95/100), followed by smart features (94/100). In practice, auto-fill mop tank (30 days).
The main caveat is battery life, where it scores 76/100. Specifically, suction not stated in pa.
At €949, it's priced around the category average. For most buyers in this category, it's one of the best choices you can make.

Does this robot vacuum empty itself?
Models with a self-emptying dock vacuum their bin into a larger bag automatically, so you only empty it every few weeks. Check the “self-emptying” spec above.
Can it avoid obstacles and pet messes?
Robots with AI camera or reactive obstacle avoidance steer around cables, shoes and pet waste. LiDAR handles mapping; a camera adds object recognition.
How loud is it?
Most robot vacuums run between 55–70 dB — about as loud as a normal conversation. See the noise level spec for this model.
Does it work on both carpet and hard floors?
Yes. It auto-adjusts suction on carpet, and models with a liftable mop raise the pads to avoid soaking rugs.
