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.
