Sonic Vibration or Rotating Pads?

Both are effective ways to mop. They simply work differently, so the right choice depends on your floors and the messes you deal with most.

Sonic vibration · Saros 20 Sonic

The VibraRise 5.0 mop combines 14N of downward pressure with 4,000 sonic vibrations/min for powerful scrubbing, and its extendable mop head presses into edges and corners. Well suited to dried-on stains, sticky spills and edge cleaning.

Rotating pads · Saros 20 & Saros 10R

Two round mop pads spin against the floor, wiping as they turn. A proven all-rounder for everyday mopping across larger areas, with mops that detach automatically for carpet cleaning.

Notes

1. Images and videos are for illustration purposes only and may not exactly represent the product. The app interface is subject to change without notice.

2. Suction: based on internal testing of the digital motor under specific conditions. Actual results may vary depending on product configuration and usage conditions.

3. Threshold crossing: based on internal testing where the first threshold does not exceed 4.5 cm, the gap between thresholds is 12–14 cm and the second threshold does not exceed 4.3 cm. Actual performance may vary.

4. Mopping pressure: compared with Saros 10. Larger vibrating area: compared with previous Roborock vibrating robot vacuums. Based on internal testing by the manufacturer.

5. Carpet cleaning: industry-first dynamic carpet cleaning was introduced in Q3 2025 on the AdaptiLift Chassis. 30% higher dust pick-up compared with previous Roborock robots on 2 cm long-pile carpets in Max+ mode. Carpet settings must be enabled in the Roborock app and apply to carpets up to 3 cm pile.

6. Low clearance: the body height is 7.98 cm. Slight flexibility in the front structure allows access down to 7.95 cm; scraping may occur.

7. Hot water: water at the dock's clean-water dispensers can be heated up to 100°C at standard atmospheric pressure. Bacteria removal tested by TÜV Rheinland on E. coli and S. aureus under default self-cleaning mode (Certification ID 0000087672).

8. Warm-air drying: air at the base outlet can reach 55°C at standard room temperature.

9. Obstacle recognition: the robot can see and bypass objects as small as 3 cm wide and 3 cm tall.

10. All other figures are based on internal testing by the manufacturer. Actual results may vary depending on the home environment.
