This robot vacuum is really impressive, we actually reviewed it back in 2020 when it first launched. There’s not a lot that’s special about this robot vacuum, as we called it the “no-frills” robot vacuum in our review. That is because it doesn’t add in a bunch of gimmicks and even leaves out the mopping functionality. So that Roborock could provide you with an excellent robot vacuum at a low price. And that was when it was normally priced at $429. The Roborock S4 Max  sports the same LiDAR setup as some of its other robot vacuums. So it can easily navigate your home, and do a good job of spot cleaning. It also uses some pretty powerful suction, we’re looking at 2000Pa. Which is going to be strong enough to get up all of the dirt, dust, debris and even pet hair off of your floors. It also supports multiple floor maps. So if you are one that has a multi-floor home, you can still use this one on each floor, and it’ll easily know where it is.
