Quiet, that's about the only good quality
UPDATE: Moving to 5 stars! Quickly after my 2 star review (below) the seller reached out and askked to exchange the defective product for an upgraded model at no cost to me. They were attentive and quick in responding, and I received a replacement version that also included the mopping functionality (The first didn't have this), and it works as expected. Customer service was too notch. I wouldn't hesitate to buy again. This is a lot quieter than my original Roomba, that is still running strong...but I wanted a 2nd robot vac so I could run one on the main floor and 2nd floor of my home. This one doesn't fit the bill, and I will be returning. I ran it while I was at home, and it stopped 4 times, telling me I needed to clean the brush. There was absolutely nothing bound on the brush any of the times. But had I not been home, it wouldn't have finished cleaning because it stops completely when it thinks there is hair. Then, another time, it just stopped running. It didn't say anything, so I don't know why it stopped. I assume it thought it was done, but the whole level of my home wasn't finished. This was all in just the one time I attempted to run it for 1 cycle. When I pushed the start button again, it said something to the effect of starting cleaning, so that's what makes me assume the last cycle was over. It does clean well, and is very quiet; however, it just stops for no reason far too often. I want it to run while I'm at the office, which obviously won't work if I have to be here babysitting it for the imaginary dirt on the brush. This will unfortunately be getting returned. I think I'll stick to the Roomba brand, as I have far less issues with my 10+ year old vac than this new one with all the nice features.

Decent robot vacuum, but struggles with dog hair
The setup was straightforward and the self-empty station is a nice feature. It navigates the house fairly well and does a decent job picking up everyday dust and debris on hard floors. Where it struggles is with dog hair. With a shedding dog in the house, I noticed it tends to leave behind quite a bit of hair, especially along edges and in areas where it tends to accumulate. It works better for lighter debris but doesn’t seem powerful enough to keep up with heavier pet hair. Pros: Easy setup and app integration Self-empty station is convenient Navigates rooms fairly well Cons: Struggles with dog hair Not as strong as expected for pet households Bottom Line: This vacuum works fine for general cleaning and light debris, but if you have a dog that sheds a lot, it may not keep up as well as expected. For pet owners specifically, it might not be the best fit.

Very Disappointed with this Vacuum
After having a Shark Robot Vacuum for many years, my husband decided to upgrade to newer technology (easier boundary settings, better mapping etc) On a good note, when this thing works - it works great. One of my biggest complaints with the Shark was I had to put physical boundary strips at the top of the stairs etc. This Eufy is very easy to set "no go zones" on the app, works famously in that aspect. This vac also seems to "work" in a more organized manner. I can see on the app exactly what was cleaned after every scheduled cleaning etc. The Shark would just buzz around the house all willy nilly, but this Eufy seems to be very organized in the cleaning, not missing anywhere. Now for the most aggravating part. I have my Eufy scheduled to clean every night @ 1:00 am, while we are sleeping. Most nights @ 1:15 am I get a notification on my phone "Roller Brush Stuck". Well obviously I don't see the notification until morning. I go "find" Eufy (which is easy with the app - shows you right where she is - another nice thing compared to the Shark) Pull the Roller Brush, which mind you, nothing is wrong with, it is not stuck, there is nothing wrapped around it etc. Put it back in & restart. This has done this since day one, brand new out of the box. After doing some scouring of the Internet, I see that this is a big complaint with many other owners of this model. From what I gather, Eufy is aware of this and it is a known problem. I called Eufy Customer Care after about using this for one week. The phone call lasted over 45 minutes (part of my life that I will never get back!) Now mind you, the representative was very helpful & thorough. We walked through a couple procedures, (The Rep had me pull the roller brush etc & report to her what I was "seeing") Which again, I had performed everything the Rep had me do religiously for the past week, but No, she like wouldn't take my word for it, I had to do all this again while on the phone with her - - almost like she didn't believe me at first. Next, the Rep offered to send me a "newer design roller brush" Ok, cool, if it solves the problem let's do it - I just wanted to get off the phone & on with my day. Oh wait, there are no new design roller brushes in stock. Now I'm told to send just the robot back (not the dock) I told the Rep to send me a call tag, as I wasn't going to pay shipping on a "brand new used one week" item. Oh wait, now she has located the replacement roller brushes. So here we are back to the original solution, she will send me a replacement roller brush. Took my name, my address, phone number, name of first & last born children etc. Just a long drawn out process to send me the "fix" for their known manufacture problem. So to make my long story even longer, here I sit a month and a 1/2 later without ever receiving the replacement brush and an unreliable product who doesn't complete her "mission" most nights. I wish this vacuum was still within the 30 day Amazon return period, because I would have sent it back after experiencing this defect. However my husband had bought this for me for Christmas (before the date that Amazon offers their extended holiday returns window) I didn't even unbox this vacuum before the 30 days were up. The App with the mapping & the expansive scheduling options is great compared to the Shark, but I bought the Eufy to vacuum, which she fails @ nightly.

Absolutely amazing! Working flawlessly for over a month, so far.
Color: White
I am very pleased with the performance so far. The strengths are the ease of setup, the accuracy of its mapping and carpet/floor recognition, the quality of its cleaning and mopping, and the entertainment of just watching. There are weaknesses. The documentation is sparse and pretty useless and tech support has been ghosting me..no responses. So hunt and peck with the App, mostly. Hard to really customize by trial and error. While it vacuums very well, it does not empty as well, really requiring the owner to manually empty the dust bin. No big deal. Maintenance recommendations are hidden on the website and I suspect it is advisable to do some maintenance after every use. The strengths win, however.

User friendly, Pet Hair Approved, Quite Powerful Robot Vacuum
Color: White
We prviously had an Eureka E10 vacuum and mop robot for 4 years. We had no idea what we were missing until we purchased this Narwal Freo X10 Pro. It maps very fast. It is extremely quite. The vacuum then mop with a refreshed mop head solution is much better than dragging around a robot mop pad with no way to clean it without removing and washing it. We have 3 Australian Sheppards that shed alot. This was the number one concern, whereas the prvious unit needed daily attention. Not a single hair tangle in the floating rotating brush of this unique Narwal Freo X10 Pro Robot vacuum. 4 months of no robot management is wonderful. The application was easy to use with a ton of customizable options. The AI option to recognize various floor types and throw rugs ensures a complete clean and quick simple setup. Lastly the price vs product was very reasonable. Great product! After spending many months researching, we are glad we made this investment.
