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.

Great upgrade from my old robot
Size: Freo S, Size: Freo S
I had a different robot vacuum for a little over four years, and it finally started giving out, so I decided to try this one. It’s definitely an upgrade. The first thing I noticed is that it runs much quieter than my old one, which I really appreciate.
The self-emptying feature is super convenient as I don’t have to dump the container every single day like I used to. It mapped my home surprisingly fast. It moved through each room for a minute or two and somehow had the whole layout figured out almost immediately. I did adjust the room boundaries a bit, but nothing complicated.
Cleaning performance has been solid. I usually run it on the highest suction because I have a cat and a couple of carpeted rooms, and it handles the hair pretty well. For hardwood, there are lower modes too. It also has a mopping feature, but I don’t use it—I prefer my regular steam mop for that.
Setup was easy, and connecting it to the app took just a moment. And it charges quickly too.

Great value, Easy Set-up
Size: Freo S, Size: Freo S
I just got this vacuum and honestly, I’m pretty happy with it for the price. Here’s how it’s been going so far.
Price: This thing is a steal. Works just as well as some of the more expensive ones I’ve had.
Set up: It took maybe 5 minutes to get it going, and I didn’t even need to look at the manual. Super easy to set up and start mapping.
Carpet: Does a great job picking up dog hair and dust on my low-pile carpet. Doesn’t miss a spot.
Thresholds: It goes over low doorways and small lips—no getting stuck.
Navigation: It uses structured light for obstacle avoidance, which is typically found in much higher-end models, and it really exceeded my expectations. The cleaning path is smooth, and it avoids furniture without bumping into anything. It just works.
Base station: Very hands-off. It docks and charges itself. Plus, I love how sleek and simple it looks.
