My favorite robot vacuum! Works awesome!!
Size: 11S MAX, Size: 11S MAX
Eufy is by far my favorite robot vacuum brand we had one for several years and it did amazing with everything from dust to hair and even rocks didn’t phase it! It is super easy to set up, turn on, the settings are very user friendly and emptying the dust bin is super simple! They are very powerful but also compact and can fit in smaller places so that’s great for us and even when I don’t think there’s much on the floor it always gets full! You honestly can’t beat the price for how great these awesome little vacuums work definitely get your value for your money! I was a little skeptical getting the refurbished or Like-New one but I am super impressed so far! So grateful for tools like this to have around that are great at lending a hand 🤩

Sort of OK Budget model
Size: 11S MAX
I'm giving this model 5 stars because at this price, especially "renewed," it's a great robo vac. It is NOT anywhere near the hands-off level of other machines. It can't map the rooms, bumps its way around fairly successfully, but needs frequent hands on to fix something. In my case, with 2 long-haired cats, the most frequent issue is tangled hair in the roller. The machine stops dead and sends out 4 beep distress sounds for a while, then shuts down. Also, the remote seems to work only in line of sight, so if Eufy is stuck somewhere you can't see, and you were out, to find it you'll have to hunt with your eyes. Nevertheless, if your funds are limited, top choice.
Update: After 6 months of usage, I'm giving it only 3 stars. Problems: 1) if you have long-haired cats (I do) their hair clogs the roller fairly quickly. After a while, no matter how well you clean the hairs out, you have to replace the roller entirely as hair seems to get inside it and cause the machine to stop working entirely. 2) the remote works only if you can see Eufy and it can "see" you. If it gets stuck in some place out of sight, lots of luck finding it. 3) when told to go to home base and recharge, it bumps around for a long time trying to find the way home. Bottom line: Where it vacuums the rug/floor is clean, but it takes a lot of baby sitting. Definitely not first choice unless funds are really tight.

Great value for money
I live in a smaller space (sub 1000 square foot apartment) and most of our floors are hard wood, with a couple of rugs thrown in for good measure. Over the years we've had numerous robotic vacuum cleaners from various manufacturers. Our needs with this one were simple. We wanted a device that was controllable via app and virtual assistant (Alexa, google home, etc.). The ability for the device to map our living space and for us to name rooms and choose which rooms. to vacuum in any given session was a deal breaker. I wasn't looking for a device with a built in mop - though this turned out to be a huge boon, and self-emptying the bin was not important to me (this device does not have a docking station that allows for self-emptying; if that is important to you then look elsewhere).
The device looks much like all previous robotic vacuum cleaners that we purchased. As does the dock. Setup was extremely simple - I downloaded the app, scanned the barcode sticker on the top of the device, and it walked me through the rest. Didn't take more than 2 minutes. I followed the instructions in the app to map my space and a few minutes (I live in a small space) all of our rooms were mapped, named and ready to go. This was about as seamless a process as it could have been.
Adding the device to my virtual assistants (Alexa and Google Assistant, for now) was very straightforward and the app provided excellent instructions (with screenshots) for both. I exclusively use google assistant for this device as the commands are much cleaner. I simply say "Google, clean the Living room" and the living room is vacuumed. I can even chain commands "Google, clean the Living Room and the Kitchen" and it will selectively clean the mentioned rooms. Alexa's commands were a bit more arduous to use/remember (something along the lines of "Alexa, please ask Roborock to...." - I honestly can't even remember). I believe this to be a result of how Alexa's skills work, and outside of the control of Roborock.
The vacuum cleaner cleans hard wood floors and rugs very well and I've yet to encounter a case where the floors were not spotless after a cleaning session. I can't speak to thicker carpet since we do not have any, but I'm really impressed by the cleaning and the bin in this device appears to be larger than previously owned devices because it lasts a few sessions before needing to be emptied.
Mopping. I did not buy this device for its mopping capabilities but I'm really glad to have them. I read other reviews that suggested that the mopping was not useful, but I strongly disagree. Perhaps if you had a big mess, or sticky floors, then the (wetted) pad that drags along the ground when cleaning could not clean up sufficiently but when used more in a maintenance mode (i.e. I utilize the mop *every* time I turn on the vacuum) it keeps the floors nice and clean. Is it as powerful as higher end mopping devices? Absolutely not. Does it keep the floors nice and clean? Absolutely. What you need will largely influence your perception of the mop but to me this is a great add-on when used frequently.
Finally, the ability to schedule vacuum session has been wonderful. Within the Roborock app I set up routines to clean various areas of my apartment on schedule. For instance, I schedule the vacuum to clean the Kitchen and Dining Room every morning after breakfast (8am) and every evening after dinner (7pm). The vacuum takes care of the rest and in a house with children this kind of scheduled and automatic maintenance greatly reduces crumbs and mess.
This is a very cost effective device that feels like more of a luxury than I could have expected. It fits my needs perfectly and I absolutely love it.

Oooooh this little guy packs a punch!
Color: Black01
I dont know what the heck took me so long to get this little gadget. I absolutely love it and now can't imagine being without it. I can't compare it to the other big names, I just simply can't afford those! But I can tell you this little guy packs a huge punch on results!
1st I must tell you my house is vey small, maybe 1600sq ft inside, only 2 bedrooms. I have no foot traffic at all. No kids. No pets, No shoes inside-sorry thats just the way my husb & I live. So I run my Robo 2 times a week only and he still picks up massive amounts of lint, rug fibers, dust etc.... Programing is super simple, easy to change plans, various options on suction and tweaking the areas you want covered. Robotic absolutely fabulous. Don't be sketched-out on its price point. Seriously its low price is freakin worth it! Like I said I dont know how it would compare to Roomba, and I actually dont care because Roborock is amazing!!! Love Love Love it!!!!
