Deeper cleaning of dust in corners

Extendable brushing and mopping arms for precise edge cleaning

Dual mechanical arms dynamically extend and retract the side brush and mop pad to effectively clean along edges and in corners, for wider edge coverage and more efficient cleaning.

The side brush extends and retracts flexibly as needed

When a corner is detected, the side brush actively extends to achieve zero-distance edge cleaning for a deeper clean.

Outward, flexible mop pad extension delivers millimetre-level edge cleaning

The vacuum automatically extends the mop pad to clean along walls and around obstacles, reaching as close as 1mm* for more efficient edge cleaning.

15,000Pa powerful suction fan blower* eliminates stubborn dust efficiently

Equipped with a flagship proprietary high-speed fan and aerospace-grade aluminium-magnesium alloy fan blades, the vacuum delivers enhanced cleaning performance, efficiently removing hair, fine dust and daily dirt from floors.

Dual-mop pad rotary cleaning for high-efficiency dirt removal

The vacuum simulates a hand-wiping motion to effectively remove dirt from floors. Its water tank features adjustable flow, ensuring the mop pads stay optimally wet for deep cleaning with minimal water stains.

Say goodbye to hair tangling*

Dual anti-tangle system for the whole vacuum means less hassle for you

The innovative Y-shaped anti-tangle roller brush with bristles and an anti-tangle side brush provide a safe and efficient solution to hair entanglement so less maintenance is required overall.

Anti-tangle design on two ends of the roller brush

Integrated end caps tightly seal the sides of the roller brush, effectively preventing hair from being pulled in from the ends.

Clean a 180m² home in one go without needing to worry about battery life or running out of water

Equipped with a 5200mAh* large-capacity battery, a single charge powers vacuuming and mopping across an area of up to 180m²*. Featuring a 310mL water tank and a 430mL large dustbin, it ensures continuous water supply for consistently wet mopping and efficient cleaning.

Nimble obstacle avoidance

The smart carpet-recognition system automatically lifts mop pads to keep carpets dry

Equipped with ultrasonic sensors, the vacuum automatically lifts the mop pads by 10mm* upon detecting carpets to prevent them from getting wet. At the same time, you can enable automatic carpet boost to powerfully remove dust embedded deep within carpet fibres.

Clean carpet first: Low-pile carpetsVacuuming prioritised

Carpet avoidance: Long-pile carpetsIntentionally avoid

Carpet crossing: Bathroom matClimb over, instead of vacuuming

Ignore carpets: Rooms with no carpetsVacuum and mop according to your preferences

Prevent secondary contamination

When cleaning is complete, the vacuum returns to the charging dock and automatically retracts the mop pads.

129° wide-angle laser scanning is precise to the millimetre to avoid getting stuck

Equipped with a wide-area structured light obstacle avoidance system, its 129° ultra-wide field of view allows the vacuum to detect low-lying obstacles. It navigates precisely and avoids collisions with ease, even in low-light environments.

Identify obstacle edges

Real-time measuring to avoid collisions

Anti-fall edge sensors

Stair detection to prevent falling

Edge-detection sensor

Precise drop recognition during close-edge cleaning

20mm obstacle-climbing* capability

Easily cross thresholds and continue cleaning

Equipped with a smart floating main brush cover that automatically adapts to varying floor heights and a durable brushless motor, the vacuum easily climbs over obstacles up to 20mm high. These features reduce the risk of collisions and getting stuck, ensuring smooth and efficient cleaning.

Efficient autonomous cleaning

LDS laser navigation with 360° scanning for quick mapping

Featuring cutting-edge LDS laser navigation, the vacuum performs a 360° scan of your home, quickly creating an accurate map. It remembers your layout for seamless cleaning without repeated scans.

Quick mapping

Route planning

Multi-storey mapping memory

Resumes cleaning where it left off

Automatically plans cleaning routes using comprehensive S-curve coverage

Every cleaning step is accounted for, allowing the vacuum to operate normally under both low and bright lighting conditions.
