Is the Roomba j9+ worth it over a Roborock?

It depends on your priorities. If you want the best pet hair brushes, US-based support, P.O.O.P. guarantee, and seamless smart home integration, the j9+ is worth considering. If you want more features per dollar (mopping, stronger suction, LiDAR), Roborock is a better value.

What's the P.O.O.P. guarantee?

Pet Owner Official Promise — if the robot runs over pet waste, iRobot will replace it. This is unique to iRobot and is a genuine selling point for pet owners. Competitors don't offer anything similar.

Do I need the iRobot subscription?

No, but without it you lose Smart Maps, Clean Map reports, and some scheduling features. Many owners view this as frustrating for an $800 robot. The basic cleaning works fine without the subscription.

How does camera navigation compare to LiDAR?

LiDAR is more efficient — creates faster, more accurate maps and covers rooms in organized rows. Camera navigation works but is slower, can miss spots, and requires ambient light. For dark rooms (under beds, at night), camera navigation struggles.

The j9+ has better suction and an improved brush system, but the j7+ at $600 offers nearly the same experience. Many owners recommend the j7+ as the better value unless you specifically need the incremental improvements.

Owner Insights

The Roomba j9+ generates conflicted discussion in owner discussions. On one hand, owners universally praise the dual rubber extractors as the best brush system for pet hair — zero tangling, easy to pop out and clean. The P.O.O.P. guarantee is frequently highlighted as a unique and valuable feature that no competitor matches. Smart home integration is the most polished in the industry.

On the other hand, the j9+ is increasingly seen as overpriced for what it offers. At $800, competing robots offer vacuum + mop, self-washing docks, and stronger suction. The lack of any mop function is the most common criticism — owners regularly note that you can get a Roborock or Dreame that vacuums comparably AND mops for the same money. The camera navigation, while improved, is also consistently described as slower and less efficient than LiDAR.

The j9+ still has a loyal following among pet owners who prioritize the rubber extractors, P.O.O.P. guarantee, and US-based customer support over raw features and value. It's most recommended for people who want a vacuum-only robot from a trusted US brand with easy smart home integration. For everyone else, the value proposition has eroded significantly as Chinese brands have caught up and surpassed iRobot on features per dollar.

Pros

+Dual rubber extractors are the gold standard for pet hair — never tangle, easy to clean
+P.O.O.P. guarantee gives genuine peace of mind to pet owners — iRobot will replace the robot
+iRobot OS smart scheduling learns your routine and suggests optimal cleaning times
+Clean Base auto-empty system is compact and reliable
+Camera-based obstacle avoidance reliably identifies and avoids pet waste, cables, and shoes
+iRobot's customer support is responsive and US-based

Cons

−No mop function at $800 feels outdated when competitors offer vacuum+mop for less
−Camera navigation requires ambient light — won't work well in dark rooms
−120-minute battery limits coverage to about 1500 sq ft per session
−iRobot subscription pushes features like Smart Maps and Clean Map reports behind a paywall
−Suction specs aren't disclosed and real-world carpet cleaning trails LiDAR competitors
−Camera navigation is slower and less efficient than LiDAR — more zigzag, more missed spots
−Amazon acquisition and subsequent layoffs have worried some about long-term support
