Roborock Saros 20 is now on sale: 7.95cm tall but overcomes thresholds of 8.8cm, washes at 100°C and even makes video calls
If you're looking for a vacuum cleaning robot that can do everything without needing much intervention, the Roborock Saros 20 Set is probably the most advanced product available today on Amazon. With a suction power of 36,000 Pa, the ability to overcome thresholds of 8.8 cm, a profile of only 7.95 cm, and a mop washing system using hot water at 100°C, this robot sets new standards for automated home cleaning in 2026. It is currently available on Amazon for €1,289, with a 14% discount from the list price of €1,499. A price drop that makes headlines, considering this is a product recently launched on the market.
The most fascinating technical paradox of the Saros 20 is this: how can a robot 7.95 cm tall overcome steps and thresholds up to 8.8 cm? The answer lies in the exclusive AdaptiLift Chassis 3.0 system, which dynamically lifts the robot's frame during the crossing phase, all through independent and coordinated raising of the body and lifting of the main brush and mops. This allows it to tackle double step edges (4.5 cm + 4.3 cm) and clean deep carpets up to 3 cm without losing an ounce of suction power. No other consumer robot available today offers this obstacle overcoming capability with such a slim profile.
The Roborock Saros 20 eliminates the traditional protruding LiDAR turret in favor of the StarSight 2.0 navigation system, integrated directly into the machine body. This system combines advanced 3D Time-of-Flight sensors with RGB color vision that projects over 21,600 sensor points at a sampling frequency 21 times higher than traditional rotating LDS systems. The practical result is autonomous recognition and avoidance of over 300 types of objects, including small obstacles down to 2x2 cm such as cables, socks, toys, and shoes. Maps are built and updated in real time, for comprehensive coverage with fewer interruptions and always optimized paths.
The suction power of 36,000 Pa generated by the high-speed digital motor of the Saros 20 is enough to easily suck dust, pet hair, hair, and debris even from the deepest crevices of floors and carpet fibers. For pet owners, the real novelty is the DuoDivide anti-tangle system: a dual counter-rotating roller tackles hair and fur from the main brush, while the FlexiArm Arc side brush is also equipped with anti-tangling protection. The result is minimal manual maintenance of the brush, even in homes with long-haired pets.
Thanks to the absence of the LiDAR turret and a redesigned interior, the Roborock Saros 20 measures a total height of 7.98 cm (with dynamic lowering to 7.95 cm during cleaning). This allows it to slide under sofas, beds, and furniture that other robots can't even approach, reaching hidden dust, hair, and invisible allergens. The FlexiArm Smart Reach technology extends the side brush and mop cloth towards corners, baseboards, and under furniture areas. From the app, it's even possible to mark the position of curtains: the robot will recognize them and clean behind them without ever getting tangled.
The brand new RockDock multifunctional station included in the set represents a generational leap compared to previous charging bases. The new single-piece cleaning tray increases the panel coverage and water capacity for a deeper wash and quieter operation. Thanks to the mop washing cycle with 100°C water and hot air drying at 55°C, the cloths are sanitized and dried after every session, eliminating bacteria and bad odors. The station also autonomously handles emptying the dust collector for up to 65 consecutive days without user intervention: a value among the highest in its category.
The Roborock Saros 20 is fully controlled via the Roborock app, compatible with 2.4 GHz and 5 GHz WiFi. The SmartPlan 3.0 feature learns household habits and creates optimized personalized cleaning plans that can be started with a single touch. The integrated RGB camera allows remote monitoring of the home at any time, with a useful live video call feature for checking on pets or children. The absolute novelty is Hello Rocky, Roborock's proprietary voice assistant that allows commands to be given directly to the robot without using a smartphone, for an even smoother and more natural experience in daily life.
