    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.

    Good value for price
    Size: Freo S
    Update - returned due to lackluster battery power. It would vacuum on “regular”, and come back to recharge after less than a hour. It’s too bad, because otherwise it was great. This is a pretty good system for the price, especially if you have primarily hardwoods/tile. It’s not great on carpet, and I really need a vacuum with more suction power. It will not remove enough pet hair from my low pile and washable rugs to make the investment worth it. Battery does not last as long as other models I’ve tried. It returns to recharge many times for my 3000 sq ft. I have a multi level house, with multiple thresh holds (home has many additions). I need a vacuum that can save 6 maps. This only saves 3 - which to be fair is typical in this price range. I don’t even know if there is a vacuum that can save 6? WiFi was easy to connect. Not too noisy when running. Seems well-made. Just needs more suction for my needs. Overall this is a decent system for this price point. I need something more powerful so I’ll probably be upgrading.
