Swing and a miss
We were given this as a warranty replacement for put J series. I was initially excited seeing the mopping pads thinking we would get a better clean, but I was wrong. The mop pads just drag fur around our house. Most of the time, even if doing the vac then mop setting, the floor looks worse after. I think the single roller is also a part of the problem and debris isn't funneled into the middle. It did solve the issue were having by having vertical charging contacts vs ones on the base/floor. Roomba's warranty replacement program was breeze to work with when we had an issue, but sadly this new one is almost pointless in our house. Maybe if we didn't have pets this design would work better🤷♀️

504 vacuum only robot
I bought the 504 vacuum only. I have a two story home and was able to access which map I wanted. About a month after I bought this an update was completed and I am no longer able to switch maps so I cannot do a targeted run. From what I have read it is suppose to knew which map to use however, without being able to do targeted runs I have to run the whole upstairs every time. Please give us back the option to change maps.

a very expensive piece of decoration
I am incredibly frustrated and disappointed with iRobot. I purchased a Roomba Combo j7+ in November 2023. Within a relatively short time, it started having problems. It was sent for repair twice, without the issues being properly resolved. Eventually, iRobot replaced it with a cheaper model, the Roomba Plus 505 Combo. Unfortunately, the replacement didn't last either. After around a month it started repeatedly going offline, and after approximately two months, following the first dust-bag change, it stopped recognising the bag altogether. I only use genuine iRobot accessories purchased directly from iRobot, so this is clearly not a third-party accessory issue. The result? My Roomba has now been sitting unused for around five months. What frustrates me most is that I have spent an enormous amount of time dealing with customer service, explaining the same problems repeatedly, only to end up exactly where I started: without a working vacuum. At this point, I have completely lost faith in iRobot. I don't expect anything from the company anymore — I just want to share my experience because I genuinely regret purchasing this product. I bought a robot vacuum to clean my home, not to serve as an expensive piece of decoration. Very disappointing experience from a company I expected much more from.

It's okay but...
I have a Roomba J series vacuum and it works amazing. I have a Labrador, so a vacuum that can handle heavy dog hair is a must for me. I decided to try the Combo 505 to see if I'd like the mopping feature in addition to vacuuming. Overall, I have some concerns to share. Emptying frequency: I expected it to return to the dock and empty its debris bin as often as my original Roomba does. My J series knows when the bin is full and returns to empty. The Combo 505 doesn't seem to do this as reliably or even at all. The real issue, mopping mode debris emptying issue: Whenever I have it vacuum and mop or Vacuum and then mop, the robot can't evacuate the debris from the dust bin. It will try, but nothing evacuates -- it sort of gets packed in there. Additionally, it will continue going on vacuum jobs with a full bin and debris just keeps packing in, with no error message warning that the bin is full. The vacuum will keep running as if everything's fine, but since the bin has nowhere for the debris to go, it ends up staying on your floor instead of being collected. Workaround: If you skip the mop function, the underside of the robot stays dry, and it empties debris properly, just like my original Roomba. But since I bought a combo specifically for both features, I expect it to work well in vacuum and mop mode. Bottom line: If your home doesn't deal with heavy shedding, this will probably work fine. But if you have a dog that sheds a lot, keep a close eye on the dust bin when using mop mode, since it won't warn you when it's full.

DO NOT BUY
This is the second roomba I've owned, both broke. Do not buy this. I've had it for 4 months and it's already stopped working entirely. I tried to return buy they only allow returns in a 60 day window. Aka their products will work for 60 days and not a day longer. I've tried calling technical support but it's a 2+ hour hold time, and you get no help. DO NOT WASTE YOUR MONEY ON ANY OF THEIR TRASH PRODUCTS!!!!

Do not buy
This has been the bane of my existence. This is my second roomba and this one does not work well. It gets lost all the time, it reports being stuck. It doesn’t clean the borders of the different cleaning zones. I spend more time “helping” the roomba than it would take me to vacuum and mop myself.

Lifespan of 1 month
The Roomba® Plus 505 Combo Robot + AutoWash performs exceptionally well when it is functioning properly. I often schedule it to clean while I am at work, and I come home to spotless floors. The cleaning performance itself is impressive, and I was very happy with the results initially. Unfortunately, about a month after purchasing the unit, I began experiencing recurring issues. The robot repeatedly reported that it was "lost" and could no longer navigate correctly. I followed all of the troubleshooting steps recommended in the manual, including cleaning the sensors, rebooting the device, and performing a factory reset, but none of these solutions resolved the problem. After contacting customer service, a replacement unit was sent to me. While I appreciated the support, the replacement robot worked well for only about a month before developing the exact same issue. I am now contacting customer service for a second time regarding the same recurring problem. It's disappointing because the product is excellent when it works, but having two units experience the same failure after a short period of time has made me question the long-term reliability of the product. At this point, I am uncertain whether I would purchase this model again.

Breaks - app is useless
It cleaned well for a couple months. The first one broke within a couple weeks. One of the mop wheels would not extend. We replaced it and this one lasted longer. Same issue. Now this one gets lost. It will say its trapped behind furniture when its sitting in the middle of the floor with nothing around it. Tried cleaning the lidar and sensors, but nothing helps.

Highly disappointed
This is not working as expected and I am highly disappointed. Plus, the owner's manual doesn't even include how to use the mop function, what cleaning soluton to use, or how to add cleaning solution. We have a dog who sheds daily. This Roomba model is what was recommended to buy based on the quiz I took. We have hardwood floors and area rugs. The Roomba is leaving clumps of dog hair when it transitions to a different floor type. It is also leaving too much dog hair behind. I have to go around with my regular vacuum to vacuum up everything that the Roomba doesn't get. What is the point in having a Roomba if I have to vacuum afterwards? For this amount of money and the time I am supposed to be saving, this should not be happening! It is not even hitting every clear area! I've tried it on every setting and it is still a total fail. I have troubleshooted by making sure the dust bin is clear, cleaning the roller, and wheel. Doesn't make a difference. What a rip off.

Mixed results
When this roomba works, it works well. It definitely mops better than its predecessor. I have owned mine for almost a year and have encountered a number of problems. I have had to factory reset it twice when it just seemed to forget the map and therefore wouldn't do the automated cleaning schedule. It will think its on a cliff when sitting in the middle of the floor with no obstacles near it. It frequently will go into the dock then back out and say it can't find the dock. None of these are consistent errors so troubleshooting is challenging. As I said before, when it works it is great. Unfortunately its a roll of the dice as to whether today is a good day or a bad one for it. I would not buy it again and will eventually replace it, most likely with a product from another company. Its unfortunate. I've owned many roombas over the years and some have been better than others. I have a 300 series that is dumber but much more reliable, assuming the app will actually connect with it but that's a different review. I can at least go hit its power button and it will happily clean the lower level of my house without complaint. I wish this more expensive 505 series roomba was that reliable

Too tall
I upgraded to the 505 plus combo from a 980 as I wanted something that would mop floors as well. The turret on top of the 505 means it does not want to venture under furniture like the 980 would, even though it will easily fit, and it leaves pet hair along the edges of rugs, which is likely coming off the mop heads. I like that it doesn't make the floor soaking wet and is quiet when mop drying, and the bin bag takes months to get full, despite having a cat and a dog and using it regularly. I would definitely buy Roomba again, but not one with the turret on the top.

The worst product and customer service-
Absolutely disgraceful company. I have been a loyal customer since 2015, but that ends today. I've reached out regarding a replacement for a defective, low-quality robot, only to be told they won't honor the warranty because it was purchased through bank reward points. If iRobot chooses to participate in these point programs to sell their products, they should be required to stand behind them. Instead, they use it as a technicality to abandon their customers and avoid replacing their faulty equipment. To make matters worse, they don't even provide a clear or easy way to recycle this "piece of junk" and refuse to provide a box to take it back. Do not waste your money on a company that rewards a decade of loyalty with "maintenance tips" for a machine that doesn't work. They are happy to take your money but will disappear the moment their product fails.

Squeaky Clean
[This review was collected as part of a promotion.] OMG love this vaccum+mop. It vacuums so well picking up all my dogs hair. Love the sensors as it goes around toys and stuff. We use distilled water for the mopping and works great even if we have rugs will not mop on it will only vaccum on it. Emptying is loud lol but great. Charges well for my space everyday use.

No floor cleaning solution included.
I just recieved my new Roomba on Friday (05-01-26), but I can only review the vacuum portion at this time, because the floor cleaning solution was NOT included with the unit. For the price, the company should have included at least one bottle. I tried to purchase some directly from iRobot, but it's sold out. The vacuum works well. I am eager to see how well the mop function works, but I'm waiting for cleaning solution to arrive. :0(

Excellent mop/vac combo with some connectivity hur
[This review was collected as part of a promotion.] I really wanted to love the iRobot Roomba Combo 10 Max. On the positive side, the vacuum and mop combo is fantastic—having one machine handle both surfaces is a huge time-saver, and the floors look great when it's finished. However, the "automation" part falls short. I find myself having to check the app every couple of minutes to troubleshoot or "help" it get back on track. It’s a powerful cleaner, but be prepared to stay close by while it’s running.

Doesn't fit under furniture or avoid obstacles
iRobot sent me the Plus 505 combo ostensibly as a replacement for my beloved j5+ that broke its POOP Promise. But the 505 is not a replacement for the j5+: it can't go under my furniture due to the LiDAR turret, and it doesn't avoid obstacles. Most cleaning runs result in it getting stuck trying to eat a sock or cord, or on an inch-tall obstacle.
