| Mopping | None - vacuum only | Basic drag-along mop pad with water tank |
| Self-empty base | Holds ~60 days, reliable extraction | Holds ~45 days, also reliable |
| App & value | Best-in-class app, high list price, frequent sales | Very good app, more features per dollar |
Obstacle avoidance iRobot Roomba j7+
This is the j7+'s whole identity. It recognized and photographed a phone charger, a sock, and a charging cable in testing, and navigated around all of them. The Roborock treats obstacles as things to push.
If you have ever watched a robot vacuum smear a pet accident across a rug, you already know how much this matters. It converts a robot from something you tidy up for into something you just run.
Suction & carpet Roborock Q7 Max+
The Q7 Max+'s higher rated suction translates into better deep-carpet pickup, and its bin holds more before the base needs to intervene. Both are excellent on hard floors.
Mopping Roborock Q7 Max+
The j7+ does not mop at all. The Roborock includes a basic mop pad that damp-dusts hard floors - not a real mop, but it picks up the film of dust a vacuum leaves behind. If mopping matters, this round ends the comparison.
Self-empty base Tie
Both bases work well and both turn daily robot ownership into a bi-monthly bag change. The iRobot base is slightly larger; the Roborock's is quieter during extraction.
App & value Roborock Q7 Max+
iRobot's app is the more polished of the two, with better mapping and keep-out zones. But the Roborock typically costs less and includes mopping, which is more machine for the money - provided you can live without the smarter avoidance.

Frequently asked questions
Which one is better for a first robot vacuum?
The Roborock if you want the most features and your floors are tidy; the Roomba if you have pets or cables and need a robot that will not make mistakes.
Do both include a self-empty base?
Yes, both models in this comparison ship with a self-empty dock, which is the single biggest quality-of-life upgrade in robot vacuums.
Is mopping on the Q7 Max+ any good?
It is a damp-dust mop, not a scrubbing mop. It is genuinely useful on hard floors and not a substitute for real mopping.
