Up to 100°C roller washing, 63°C warm-air drying, automatic detergent dosing, hot-water refill, and dust emptying
Test evidence
Computer Bild measured 99.6g pickup from a 100g mixed-debris test and found streak-free roller mopping
Product Overview
Roborock Saros 20 Flow Complete replaces rotating pads with a pressure-fed roller that receives clean water through 16 outlets while dirty water is separated during the pass. The robot combines 36,000Pa suction, an 8.98cm body, retractable LiDAR, carpet shielding, a lifting chassis, and a dock that washes the roller with hot water. Independent testing found excellent pickup, navigation, obstacle avoidance, and streak-free mopping, but also noted small onboard dust and water containers. Regional rollout and final pricing remain uneven.
What Stands Out
Its SpiraFlow 2.0 roller is continuously supplied with clean water and scraped during use, reducing the tendency to drag the same dirty pad across a room while still lifting and shielding the wet roller over carpet.
Why It Matters
The product shows a Beijing robotics brand shifting premium floor care from suction races toward fluid separation, active mop pressure, threshold mobility, low-clearance navigation, and dock automation.
Best For
Mixed hard-floor and carpet homes, pet households, tall room thresholds, and users who want strong autonomous mopping with less manual roller care.
Not For
Budget users, homes with stairs or thresholds outside the specified geometry, users who want a camera-free cleaning robot, or people unwilling to maintain onboard tanks and a large dock.
Things to Know
The 8.8cm figure applies to a two-step threshold under manufacturer test conditions: the first step is up to 4.5cm high and at least 20cm wide, followed by a second step under 4.3cm. A single abrupt threshold is not an 8.8cm claim.
The maximum 240rpm roller speed and 15N mop pressure depend on specific settings and manufacturer tests. Floor finish, stain type, water level, and cleaning mode can change results.
The official German page links to a retailer, while independent German coverage described €1,499 as an expected price. Confirm the current model name, included dock, price, warranty, voice-assistant support, and delivery region before going further.
Independent testing praised pickup and navigation but flagged the small onboard dust box and water tank. The dock automates washing, drying, detergent, and dust emptying, but dirty-water disposal, tray cleaning, brushes, sensors, and consumables still need attention.
