The reviewer concludes that the Roborock Saros 20, with its advanced wheel design, navigation system, and strong motor, is "best in class" for handling complex homes and diverse floor types, offering predictable and comprehensive cleaning. While it excels in many areas, the spin mop pads and lack of interchangeable pads are noted as weaknesses.
The video provides an in-depth review of the Roborock Saros 20 robot vacuum, testing its navigation capabilities on various floor types, suction power, and mopping performance. The reviewer also examines its design, mapping features, and discusses potential weaknesses.
The Roborock Saros 20 is a top-tier robot vacuum highly recommended for complex homes, thanks to its exceptional navigation and powerful cleaning capabilities. Its unique 'wave' motion system allows it to traverse different floor types, including squishy mats and high-pile carpets, with unprecedented ease, unlike heavier competitors like Moavas and Dreamys which get stuck. The 3D TOF navigation system provides precise, hallucination-free mapping and faster reactions due to its internal processing and lack of spinning LiDAR. However, while its hot water mopping is effective on dried stains, it struggles with sticky messes by merely sloshing syrup around due to an inability to extract water effectively. If you have a home with varied floor types and require precise, efficient navigation without getting stuck, this unit is worth the investment. If you frequently deal with sticky, syrupy spills that need thorough extraction rather than just smearing, you might need to look for a different mopping solution.

The reviewer demonstrates the Roborock S8 20 moving easily over a squishy kids' mat and a heavyweight carpet without getting stuck, noting that other vacuums like the Moavas and Dreamys struggled. This is attributed to its wheels adjusting height and having more thrust.

The reviewer demonstrates the Roborock S8 20 effortlessly transitioning over challenging surfaces like squishy kids' mats and heavyweight carpets, where other robot vacuums typically get stuck. Its advanced wheel design allows it to adjust height and provide more thrust, making it adept at navigating complex home environments and raised floors without issues, performing "best in class."
The Roborock S8 20 employs a 3D Time-of-Flight system and a fast internal AI chip to create a comprehensive matrix view of the room and objects, allowing it to react quickly without needing traditional lidar or dual cameras. This results in superior object detection, intelligent re-cleaning of dirty areas, and highly accurate, consistent, and predictable cleaning maps, as demonstrated by the various detailed maps shown by the reviewer.
The reviewer demonstrates the Roborock S7 20's 36,000 Pascal suction power by showing it effortlessly picking up mixed-size particles from hard floors. In a specific test, it successfully cleaned cat hair, dust, and debris collected from an entire floor by an upright vacuum on a single max-power, deep-cleaning run, indicating strong vacuuming performance.
The Roborock S7 MaxV successfully removed most dried coffee and coffee/sugar/cream stains on the first pass, completing the clean after its mop pads were self-cleaned with hot water. However, the reviewer criticizes its spin mop pads for being unable to extract water, leading to them spreading sticky messes around rather than cleaning them effectively.
The reviewer describes the Roborock S7 MaxV as "incredibly heavy" and solid, heavier than previous models, comparing its build to a brick. This substantial weight, combined with reinforced plastic and the ability of its mop mounts to push down, contributes to a better mopping performance by applying more pressure to the floor.
The reviewer shows the S7 MaxV's mop pads effectively self-cleaning with hot water after a single cleaning session, removing coffee residue. The water temperature was measured at about 108°F directly from the mop pads, with the hottest water being delivered to areas closest to the self-empty station at the start of the mopping run. Users can also manually adjust the hot water settings.
The reviewer criticizes the Roborock S7 MaxV Ultra, noting it lacks interchangeable mop pads. This means the robot reuses the same mop pad throughout a cleaning cycle, which can be a significant drawback for larger homes where the pad might become saturated and dirty before the job is complete.
100/100 source quality
The Roborock Saros 20, presented as Roborock's 2026 flagship, offers significant upgrades, particularly in navigation across varied floor types, including "squishy" mats and high-pile carpets, due to its adjustable wheels and powerful motor. Its 3D TOF system and faster AI chip enable superior object detection and precise mapping, leading to predictable cleaning routes. The S7 MaxV demonstrated strong suction power and effective hot water mopping, though its spin mop pads were criticized for not extracting water. The robot's heavy build and reinforced plastic contribute to its solid feel and durability.
