Bests & Worsts Reviews from Amazon

This is a really great robot vacuum with tons of great features. I originally tried a competitor’s robot because of a sale, but decided to try the Roborock robots because of the LiDAR navigation. My first foray into the Roborock lineup was the S4–excellent navigation, reasonable ability to clean on low pile carpets, superior cleanup of dog hair from a high-shed breed...however, the robot struggled with going over thresholds between my kitchen, dining rooms, and bathrooms. That’s where the S4 MAX really excels! This robot has all the epic features of the S4 but dominates carpets (carefully pulling dog hair out of the carpets with zero damage to the carpet) and moves with ease over thresholds. This robot doesn’t have an automatic empty bin, but it takes 20 seconds to snap out the dustbin and empty it, so I’m not putting a lot of stock into that feature. This really is the perfect robot vacuum. I did a lot of research into the available options and put 3 robots through the paces, and the Roborock S4 MAX really outperformed anything else I’ve seen. If you are looking for a really smart bot to basically automate your daily sweeping around your house—look no further!
