Robot vacuum cleaner Roborock Saros 20 with Refill and Drainage System, 6400 mAh, 200 min runtime, 2.5 L dust bin, black

Roborock Saros 20 is a robot vacuum cleaner with a built-in Refill and Drainage System for automated vacuuming and wet mopping. It combines a 2.5 L bagless dust container and a high-capacity 6400 mAh Li‑Ion battery that provides up to 200 minutes of runtime. The device returns automatically to its base station for mop washing and drainage, supports Wi‑Fi connectivity and operates at around 63 dB, making it suitable for regular home cleaning.

Advantages

The Saros 20 offers extended runtime from its 6400 mAh battery, allowing long cleaning cycles on a single charge. A 2.5 L bagless dust container reduces the need for frequent emptying, while the Refill and Drainage System automates mop washing and water management. Integrated Wi‑Fi enables remote control and scheduling, and the machine’s noise level near 63 dB keeps operation relatively unobtrusive.

Suitable for

• Daily vacuuming and wet mopping of apartments and homes
• Large rooms or multi‑room cleaning due to extended runtime
• Users who prefer automated mop maintenance and base‑station cleaning

When it may not be suitable

It may be less suitable for homes that require very quiet operation below the stated noise level or for users who need a very compact, lightweight unit — the product weight is around 5.05 kg. Also, if you require specialized cleaning for high‑pile carpets or professional-grade suction beyond typical household needs, this model’s specifications may not match those specific demands.

How to use

Place the Roborock Saros 20 on a flat surface and connect the base station to power. Fill the refillable water tank if you plan to use wet mopping, then set the cleaning schedule or start a manual cleaning via the onboard controls or the Wi‑Fi connected app. After cleaning, the robot will return to the base station automatically for mop washing and drainage. Empty the dust container as needed and follow the user manual for regular maintenance of filters and brushes.

What to consider before purchase

• Verify floor types in your home (hard floors and low‑pile carpets are best suited for wet mopping)
• Assess whether the device weight (~5.05 kg) and dimensions fit storage and handling preferences
• Ensure your home Wi‑Fi network is compatible for remote control and scheduling features
• Consider the need for very low noise levels or specialized carpet cleaning, which this model may not prioritize

Recommendations

Schedule regular cleaning cycles for optimal floor maintenance, keep the dust container emptied between large cleaning sessions, and use the Refill and Drainage System as instructed to maintain mop hygiene and suction performance.
