At a glance

If you’ve ever dreamed of a robot vacuum that you NEVER have to refill or empty water for, the Roborock Saros 20 with the Refill & Drainage system is here to make your dream come true!

✔ Thanks to its ultra-smart station, it connects directly to your home’s water supply and drainage, automatically filling with clean water and disposing of dirty water completely on its own.

✔ It features an incredible suction power of 36,000 Pa and the intelligent AdaptiLift Chassis 3.0 that automatically raises itself to climb over thresholds up to 8.8 cm and deep clean carpets up to 3 cm.

✔ With a height of just 7.98 cm, it slides under any furniture, while the AI camera StarSight 2.0 avoids over 300 objects, even in the dark.

✔ Its RockDock® doesn’t just do everything—it also sterilizes the mopping cloth with hot water at 100°C and empties dust for 65 days, giving you the ultimate hands-free cleaning experience!

Unstoppable movement with AdaptiLift™ Chassis 3.0

Do you have high indoor stairs or large door thresholds? The Saros 20 doesn't "hesitate"! With the revolutionary AdaptiLift™ 3.0 system, the robot lifts its wheels and entire body, managing to overcome double obstacles up to 8.8 centimeters. Additionally, if it ever feels like it's about to get stuck, it independently lifts its right or left side to free itself!

Cyclone 36,000 Pa & Zero Tangled Hairs (0%)

If you have pets at home, this vacuum will become your best friend. It features the incredible power of 36,000 Pa Hyperforce™ that pulls dust even from deep within carpet fibers. The best part? The double DuoDivide brush and the side FlexiArm brush cut and direct hairs straight into the bin, ensuring 0% hair tangling!

Industry-First: Dynamic carpet cleaning up to 3 centimeters

For the first time in the world, a robot vacuum can effectively clean carpets up to 3 cm thick! The Saros 20 detects the carpet, raises its body to maintain the perfect suction distance, and increases its power, achieving 30% higher dust collection compared to regular robots. When mopping, it completely removes the cloth or lifts it high to keep your carpets 100% dry!

StarSight 2.0 & Smart Stain Targeting with AI

Your vacuum has... eyes and a high IQ! The StarSight™ Autonomous 2.0 system uses 3D sensors and an RGB camera to see and avoid 300+ objects (cables, shoes, toys) even in complete darkness, while also cleaning behind curtains. At the same time, it detects the type of stain (e.g. liquids or coffee) and automatically changes strategy to eliminate it!

Voice Assistant "Rocky", Matter & Ultimate RockDock®

Take control with your voice! Just say "Hello Rocky" and the robot vacuum will listen to you even if the Wi-Fi is down at home, while it also supports the new Matter protocol to connect with Alexa, Siri, and Google Home. After cleaning, it returns to the RockDock® which empties the dustbin (up to 65 days hands-free), refills water, and sterilizes the mop cloth with hot water at 100°C, drying it with warm air for zero odors!

Why choose it

  • AdaptiLift Chassis 3.0: Climbs over thresholds up to 8.8 cm and frees itself automatically.

  • Powerful suction 36,000 Pa: The market's top power for spotless floors and carpets.
