Like last year’s model, it also meets the TÜV Rheinland privacy and security certification. This is important, because it navigates via AI.See—a “visual recognition technology.” Basically, it uses a camera to steer around your house. It’s not upward-facing, and Eufy assures its customers that the photos are not stored in a server and are deleted before the next cleaning cycle. However, Eufy also doesn’t offer additional security features like two-factor authentication. This is just something to keep in mind if you feel squicky about having a camera in your home.
AI.See is interesting. Its estimates of its own accuracy seem generous—I forgot to screenshot all the instances where it identified my daughter’s various hair things as poop and warned me to “clean this area immediately.” I did think it helped the robot navigate seamlessly around my house. The few times it got stuck, I found that the roller brush had become ensnared in my daughter’s or my long hair. It’s understandably much harder to see hair than it is to identify and avoid shoelaces, which tend to trip up even the best robot vacuums.
My first floor has five rooms with a total of about 800 square feet of cleanable space, depending on how widely my children’s stuffed animals are scattered at any given moment. The mapping function works quite well; it stored multiple maps on multiple floors without a problem. The battery life is decent—it can finish a whole first-floor vacuum in about an hour and a half, using about 75 percent of its battery life. You can also raise or lower the cleaning intensity, from fast to deep, and the suction power has a range from Quiet to Max.
