Robot vacuum and mop DJI ROMO S (Water Tank Version) — White, 4.4 kg, 0.26 L dust, 4 L clean / 3.2 L dirty water tanks, 5000 mAh

The DJI ROMO S (Water Tank Version) is a combined robot vacuum and wet-mop in white designed for daily cleaning of small to medium homes. It features bagless dust collection with a 0.26 L dust capacity, separate clean and dirty water tanks for continuous mopping, a rechargeable battery for cordless operation, and a self-cleaning base station that washes mop pads and empties dust.

Advantages

DJI ROMO S uses obstacle-detection technology adapted from DJI drones to detect and avoid very thin obstacles. It delivers strong suction up to 25,000 Pa and airflow up to 20 l/s for deeper cleaning, and incorporates two adaptive robotic arms to reach edges and corners. The unit supports tailored mopping with separate compartments for cleaning solution and floor deodoriser, employs an anti-tangle brush driven by dual high-torque motors, and reduces manual maintenance via a base station that washes mop pads and automatically empties dust.

Suitable for

• Daily vacuuming and wet mopping of small to medium-sized apartments or houses
• Homes with mixed hard floors and tiled areas that require mopping
• Users who prefer low-maintenance cleaning with an automatic base station
• Rooms where avoiding thin obstacles (cables, small objects) is important

How to use

Place the base station on a flat surface and fill the clean water tank and, if required, the cleaning-solution compartment according to the manufacturer’s instructions. Charge the robot on the base station until the battery is full. Use the device controls or companion app to select vacuum, mop, or combined cleaning modes, then start a cycle. The robot will map the room, extend its arms as needed to reach edges and corners, perform vacuuming and mopping, and return to the base station for mop washing and dust emptying when the cycle is complete or maintenance is needed.

Recommendations

Remove large loose objects and power cords from floors before starting, choose a cleaning solution compatible with your floor type, and periodically check or empty the base station reservoirs to ensure continuous automatic operation.
