Who needs legs? Eufy, Anker's smart home brand, believes it has solved the problem of how a single robot vacuum can clean multiple floors in your home. Its new MarsWalker robot is equipped with four arms to carry a vacuum between levels, so you don't have to lug it up the stairs yourself or buy a robot for each floor. However, you've now got two robots, so perhaps it's not really solving that problem.
In my tests, the Narwal Freo Pro did pretty well at keeping my floors clean. It has fantastic suction on hard floors, does a decent job mopping, and can clean without much intervention. However, it didn't always avoid cords on the floor, the suction performance wasn't as great on carpet, and its dust containment didn't last me near seven weeks.
The Narwal Freo Z Ultra performs impressively with its AI technology, offering powerful suction, self-cleaning features, and smart obstacle navigation, making it a highly recommended choice.
