In today’s review, I will compare Roomba j9/j9+ and S9/S9+ to find out whether the newer J9 can match the older S9.
There’s no doubt Roomba is the most popular robot brand, boasting the latest innovations and guaranteeing reliability, unlike many cheap brands out there. Recently, the company released a new 9th gen model, the J9, which many are confusing with the S9 from the S series.

You are not alone, as this is among the raging debates on many Roomba threads on Reddit.
I will compare the two so we can find out which is the best bang for the buck.

3. Is the Roomba j9 worth it?
Wrapping Up
Indeed, Roomba is a top brand with high-end robot vacuums that guarantee excellent multisurface cleaning performance. Now, having come to the end of this comparison review, it’s time I declare the winner.
Well, I like the S9 as it has been my reliable cleaning partner for 4 years and counting. It has been reliable in vacuuming my hardwood floor while leaving no scratches or damage and has been effective in picking up pet hair and other daily dirt and debris. It also has better edge and baseboard cleaning and a longer runtime. However, if you want better navigation and obstacle avoidance, the J9 is a great deal as it features PrecisionVision.
RP
Very Nice review. Thanks very much, for the comparison. Isn’t it Ironic that this type of comparison is not found on the iRobot.com site?
Also why is Roomba still using bags?!?! in its base? The Vacuum world is moving fast forward to bagless. But the constant need to have continued revenue must be the driving force to keep bags alive.

There is noticeably a bundle to learn about this. I assume you made specific nice points in features also.
