L4
Balanced size. High productivity.
At 810 mm passage width the L4 goes through a standard door frame, then cleans to within 3 cm of the skirting board. Stain-perception AI adjusts water, pressure and speed to what it actually sees on the floor.

Stain perception
Cleans harder where it's dirtier
Vision AI classifies stains in its path and adjusts brush pressure, water flow and speed on the spot — full effort on the spill, light touch on the clean run.
- Real-time stain classification
- Automatic pressure, flow and speed adjustment
- Solution flow tracks cleaning speed to cut waste
Edge cleaning
Through the doorway, along the edge
Most rivals in this class can't pass a standard door frame. The L4 does — then hugs walls and shelving to under 3 cm, where the dirt actually collects.
- 810 mm passage width clears standard doorways
- Edge distance under 3 cm along walls and racking
- 1,100 mm turning width for tight aisle ends
Perception
A 150-metre head start
A 32-beam 3D LiDAR with 150 m of range, backed by 3D depth cameras and bumper sensors, maps the building and everything moving through it — so the L4 plans clean lines and gives people and pallet trucks a wide berth.
- 32-beam 3D LiDAR, 150 m detection range
- 3D depth cameras and bumper sensors
- Re-plans live when the aisle changes
Mobile app
The whole night, reported
Every run ends with a report: route map, coverage percentage, area cleaned, water and detergent used, minutes worked. Plan routes, get completion alerts, and prove the clean happened — without walking the floor.
- Route planning and live location
- Coverage and consumption reports per run
- Completion and fault alerts to your phone
24/7 operation
The 4-in-1 workstation
Docked at its workstation the L4 empties, refills, charges and returns to work without a human in the loop. Squeegee replacement takes 30 seconds when it's finally due.
- Autonomous empty, refill and charge cycles
- Overnight cleaning with nobody on site
- 30-second squeegee replacement
