5.0 out of 5 stars Awesome New iRobot!

D.F. · October 10, 2025

I've owned and loved my Roomba 675 since 2020, and decided to purchase this model for a different level of my house. It's incredible! It was very easy to unbox and setup, and it quickly mapped several rooms and got right to work. This part of my home has hardwood, tile, short carpet, and shag carpet, and so far it does a great job with all of them. The auto-emptying tank is a really nice upgrade compared to the 675, and this model is quieter too. Very happy with this purchase, highly recommend!

The media could not be loaded. We received our Roomba very quickly. It was extremely easy to set up, it took less than 5 minutes. We were excited about this product because we have two cats. This is our first robot vacuum, we have used twice and very impressed at the ease of setting up and its practicality. It has done a great job and collecting the any crumps or cat fur. Its very good at detecting when something is its way. I wished it came with an extra bag. Noise is ok. It gets a little louder when it’s emptying out. We used it on our first floor wich has hardwood and rugs and it a great job on both.Overall we are very happy with our purchase and we would recommend it highly.

4.0 out of 5 stars Very good vacuum, mediocre Control Ap

I received my Roomba 504+ last evening and set it up today for first time use. It was very easy to unpack and prepare for use. The wifi connection to my 5G router was quick and easy. After downloading the associated Ap on my iphone, I found and read the user manual and used the Ap to start mapping. In my opinion, the Ap is very crude and weak in functionality and usability. I give it a 2star rating. Because it was not intuitive or very diversely functional. I came very close to returning this Roomba after fighting with it most the day! However I persisted trying different options on the Ap until I figured the whole first floor map was too large to vacuum in one mission. Each time the roomba would get halfway thru the map then need to go recharge the battery. After recharging it resumed vacuuming but all prior progress on the map was lost and the vacuum would start over at the beginning of the map. This has to be an error in the software. I could never find a way to resume where it last left off. To work around this problem I searched and experimented until I was able to divide the map into reasonable sized rooms, using merge and split, named the rooms and then vacuumed by room. I also set different vacuum settings for each room to optimize the battery power. I adjusted suction and # of passes per room according to usual amount of traffic. Then I started launching an automation for each Room, one by one. Im still learning the Ap so havent discovered how to string automations together by day/time. But at least Ive decided to keep this Roomba and continue testing it. The actual hardware is very good. It has good lidar mapping, good cleaning power and very configurable. I gave it 4stars for the quality and functionality of the hardware. My only complaint is that Roomba desperately needs to improve their Ap.

5.0 out of 5 stars Perfect Tool for Carpet Cleaning!

Cleaning has never been easier! This robot actually stops and assesses the situation if it comes to a roadblock and figures out another way. I have had no issues with it getting stuck, and it maps the house for easy cleaning! Two roller blades makes this unit perfect for collecting pet hair! It also has a flashlight for cleaning in dark areas. This Roomba can be programmed to clean individual rooms, or the whole house as needed! Absolutely love my new ROOMBA!

1.0 out of 5 stars If you love your older model iRobot vacuum, this will let you down

D. · November 3, 2025

I very rarely write reviews, but I feel that this is necessary for anyone who has used, or has been using, older model Roombas, and is considering a newer model (or, specifically, this one), and expecting a product that is going to perform as well as their old one, because I can promise you that this won't be the case. I love my i4, and I love it even more after experiencing the 504 for the past 25 days. I owe my i4 a nice dinner and a day of pampering for even logically thinking that the much more expensive, updated, and modern 504 could ever replace it. How silly of me.I am uncertain if this is just how this product is designed to work, or if my unit is defective. However, some of the cons are definitely not due to defective behavior and are still incredibly valid.PROS:- CLEANINGWhen it DID clean, the cleaning seemed well done. Suction was good for our laminate floor, and our area rugs seemed to get cleaned up just fine. I have zero complaints about its functionality as a vacuum, and was impressed with the job it did.- AUTO-EMPTYING DOCKIt exists. This is not really a pro over similar models that also have self-emptying docks, but as I was coming from an i4 with no auto-emptying feature, it was a big plus for me.CONS:- BUGGY, LIMITED NEW APPThe 504 can only run using the new Roomba Home app (older models use the iRobot Home app), and it cannot be connected to the iRobot app despite the app recognizing the device if you try to add new devices. Whether this is due to compatibility issues - which I'm less likely to believe because, again, the iRobot app DOES SEE the device, it just can't be added/controlled - or whether they are just forcing their new app for arbitrary reasons, I can't say. Regardless, they took the iRobot Home app and removed almost every feature that was good from it, and called it Roomba Home. I can't set quiet times where I want the vacuum to skip vacuuming for the day, I can't save multiple maps (you can only save ONE!), when the vacuum encounters an issue - which is insanely frequently - trying to get anywhere in the app and do anything is impossible because most functions are just replaced by a notification that says there's an issue, which often gives little to no information on what the issue is and the actual best way to fix it.- MAPPING WAS A NIGHTMAREThis may just have to do with the terrible app again, but it took me 4 tries to map the first floor of our house. It's not a huge space, maybe 1000sqft or so, but the mapping failed over and over. I eventually found someone on Reddit who said they got the mapping to work if they made sure their phone stayed awake (i.e. screen didn't turn off) and on the mapping setting of the app for the entire duration of the mapping process, meaning you can't use your phone while it's mapping, and you have to make sure the screen never sleeps. Once I did this, it seemed to finally save a map. This honestly should have worried me more than it did at the time, considering this was the first thing you do after unboxing. Yeah, by the way, you cannot run this vacuum unless it has a map saved. It's not possible. So when my map kept failing, I was stuck in this non-cleaning limbo because it refused to do a single thing, vacuum-wise, until it had a map. Something this supposedly smart should be able to wing it without a map if it needs to, and it shouldn't have an app gatekeeping that ability.- NEW LiDAR IS TERRIBLE (OR MAYBE IT'S JUST DEFECTIVE?)The 504 gets lost or stuck a lot. A LOT. For something that's supposed to have some of the latest navigation technology in it, I am extremely disappointed. This thing could probably get "stuck" (and by stuck, I mean it tells the app to throw you a "I'm stuck" error even though it's not stuck on anything) in the middle of a completely empty basketball court with no walls. The number of times the vacuum said it was stuck or blocked by an obstacle, only for me to go downstairs and find it in the middle of the floor, not surrounded by anything, was incredibly frustrating. I got the 504 because I wanted to be more hands-off with my robot vacuum (not having to manually empty it all the time, etc. - I just wanted to set it and forget it until I needed to change the vacuum bag) but not only was I more hands-on than ever, it was a struggle just to get it to finish the cleaning job. At least my i4 did the job (well) and when it said it was stuck, it was legitimately stuck.- IT'S LAZYI know this sounds bizarre, but hear me out. Because of the new LiDAR navigation, it "sees" obstacles before bumping into them, unlike my i4, which bumper cars itself around my house with reckless abandon. However, this sight means that it looks at an obstacle, such as a chair leg, does some weird internal risk assessment calculation, and determines that this obstacle has an incurable infections disease and it cannot go anywhere near it, even though if it would just go around the stupid chair leg, it would see that it could clean under the chair no problem. This resulted in spaces under my chairs and tables not being fully cleaned. It didn't even want to TRY any amount of problem solving to see if it could clean around the obstacle; it just chose not to. It's the laziest thing I've ever seen. Meanwhile my i4 is out here busting its butt to gently ram into every possible surface it can find in an attempt to clean every inch around it like a cleaning demon with a singular purpose.I will be returning the 504 and, honestly, probably avoiding the iRobot brand altogether moving forward if this is the trajectory on which their vacuums and support apps are going to continue. If you can find an older unit with the older technology, and that uses the iRobot Home app, then I can't recommend iRobot enough, but these new products are a huge disappointment.My i4 will be reprising its role as the primary first floor vacuum like the absolute queen it is.
