   With the reputation that they have, I would have expected much more from their latest flagship product. We end up running into errors weekly with the robot. Some weeks it’s about it not being able to empty the trash bin (too much pet hair stuck in the rollers) but most times it’s not connecting to wifi – an inconvenience but still difficult to deal with. An expensive toy at best and not a very good one.

   Why didn’t I return it? Too many other things going on that have had to take priority but one thing for sure, I will not be trusting the brand again.

   The J9+ Combo is one of the only two robots currently on the market that purport to be able to keep medium-pile carpets/rugs dry. The other is the Dreame L20 Ultra. I got both and pitted them head-to-head. The J9 is the only one that succeeded in this goal. Note, others, like Ecovacs and Roborocks can’t lift their mop pad high enough to clear medium pile carpet. I’ve been using the J9+ daily for 2 months now, and it has performed fantastically; and I’ve been using top-end robots from several manufacturers for many years. Unlike others, it created a perfect map on the first try, has never gotten stuck, detects/respects rugs, and avoids objects well. Pros: • Great mopping performance. Got off stubborn stains in less passes consistently in numerous mopping tests of different substances, such as dirt, sauce, milk, batter, cocoa, etc. (see measured test for example) • Great vacuuming performance. In my embedded rice test on shag rug, Roomba J9+ picked up 64%, compared to 42% from the L20. • Great mapping (see pics) and navigation. Just detects and handles rugs properly. Efficient pathing, never misses a spot. I don’t recommend doing a mapping run. I just did an initial “Clean Everywhere” with only vacuum, and that produced a perfect map, and did so just as fast as when the map is already in place. Tested and compared mapping on a total of 5 floors across 2 homes. • More conservative object avoidance, probably owing to the P.O.O.P. guarantee. I don’t need this and prefer more aggressive, but might be important for some users. • Less obtrusive dock. • Can clean under drapes and bed skirts, and not befuddled by glass doors and mirrors, like LiDAR-based bots. • Quick and easy to replace pads. Stored in dock. Recommend buying 12 more for ~$40 then only need to wash once a month. • Less long-term maintenance. Changing a pad on the top of the bot, from a stash stored in the dock, seems less work than: dumping dirty water, cleaning bottom of dock, refilling clean water 4x as often, and replacing pads every 1-3 months, as with L20. • Less complex, less mechanisms to break down (LiDAR, self-cleaning, self-drying). • Runs immediately, doesn’t have to take time to wash pads first. • Cleans faster. • Quieter when not running (no dryer hum). • Simple procedure to clean unknown room: 1) Carry to target room and press button; 2) it will immediately clean whole room and return to where it started. • Can co-exist with active family. You can walk around it while it works, and it’s quiet when it’s not working. • App is better designed and efficient. Can do everything in less steps. No limited combinations of settings. Can clean favorites, zones, custom rooms, everything, with Google Assistant voice control. • Works on 5GHz Wi-Fi. • Good object detection of cords and backpack straps (even low-contrast), as long as they are not stretched out in a line. Cons: • Would not mop bathroom unless I removed mats. No indication of why. Guessing there needs to be a certain amount of available hard floor to deploy mop. • Doesn’t mop within 2″ of edges. • More frequent bumping. Doesn’t bother me, but can be disconcerting to others. Doesn’t do any damage. • Doesn’t navigate well in the dark, however does work reliably in some cases, such as cleaning my kitchen. • A little louder, both bot and base. Measured 65db for base empty, vs 60db on L20. • Eats stretched out cords (no matter the contrast) • Leaves too wide of a berth around obstacles, typically 1′. • Each time switching to the app takes about 5 seconds to connect. • No spot clean button! • Mop arm elbow sharp and close to ground. When on a side angle due to one wheel on fireplace hearth, possibly ripped off piece of my floorboard that might have been sticking up a bit. Resolve by no mop zone around raised areas. • No Android widget. • Recommended to change mop pad after each use.

   This product is so glitchy! I have been on the second dock replacement since June 14th. They don’t seem to have any stock to replace the base again, and I have no idea what to do! I would not repurchase IROBOT. iRobot have been excellent at supporting us and we are now on our third base. This one seems to work well.

   Have owned a J7+ and Braava before and given the good experience with them wanted an all in one combo which refills the cleaning liquid and had a better suction. Based on the hype went with Roborock S8. BIG mistake (well that’s for another review) and after having sunk my money in a place where the sun never shines, went for what I should have gone with in the first place. Enter the J9 combo and it delighted right out of the box. Suction is much higher and the mopping is top notch. Scrubbing the mop pad feature was never a priority as it leaves residue in the machine and creates a hygiene issue. Moreover the dirty water eventually lets off a smell. It’s easier to swap the mop pad. Cons: The navigation is still the same as in S7 and could have been upgraded to a LIDAR instead but as long as it does the job, it’s fine. Would have been great if there was just a mop only mode and hopefully it can be addressed with a software update.

   iRobot J9 plus self emptying roomba combo failed to meet my expectations! -7/15/24 Ordered the J9+ Plus Combo on Prime Day at a 43% discount ! – 7/17/24 USPS delivered the J9+ , Prime day ends tonight. Getting it on prime day means I got a 43% discount. Should I say more about this deal! – 7/19/24 Failed to avoid a sticky, messy, dangerous chemical designed to capture and kill rodents in a highly visible green container on the floor causing a mess underneath the robot. Due to the dangerous and sticky nature of the chemical , cleaning the robot would require replacement of the wheels which were not available at the time. vacuum-sale.com Support suggested returning the product for a full refund and ordering a new one. Since vacuum-sale.com didn’t have the same item available as new for the same prime day price I ordered the replacement from the manufacturer who had it. I am a Roomba fan so I did not intend to write a negative review. I am just providing feedback so irobot can fix their obstacles avoidance system these days of AI before asking someone to plunge $1300 on this new product. To iRobot engineers: Please understand, Pest Control Services will occasional put similar items on floors to help combat insects and rodents where appropriate. Having pictures of such common items in your database will help avoid unnecessary frustration! You advertise this obstacles avoidance system everywhere , dont’ you? Please don’t let this happen again in my house. Here are some before and after pictures showing the mess. —Updates 7/22/2024 – Package waited for pickup all day. I did not get a text , a call , voice or email from ups. I checked the return status and found the contact number listed for the pickup was an old landline number I haven’t used in over a decade so I called customer service to rectify the error. The customer support agent told me she had canceled the return pickup; I can keep the package. A full refund will be available in 7 days in my account. I am still without a roomba but, the feeling of dissatisfaction is fading away and the prospect of having this roomba for the cost of a wheel, 2 rollers, an edge sweeper and whatever it takes to clean up the bottom cover if I can figure out how to remove that glue. If I can’t fix it, I’ll try to sell it for whatever I can get and purchase a new one for full price. While this solution is not perfect, I think it’s fair enough. I am raising my rating to a 4 star for customer service. 7/29/2024 – Side Brush Not Spinning. -Right Wheel making occasional noise and causing multiple black spots on the floor. 8/10/2024 – Back to original 3 star rating due to deceptive refund promise made 7/22
