Why the 55L / 14.5-Gallon Tank Matters
The 55-liter tank is the L50 defining feature. For facilities that run cleaning overnight with no staff present, tank capacity determines whether the robot completes its full mission without interruption. The L4 75L tank handles most mid-size facilities in one fill; the L50 55L tank handles large or multi-zone facilities.
Key Features
- SLAM mapping: builds facility map on first deployment
- LiDAR obstacle detection: stops for pedestrians and equipment
- Scheduled operation: daily windows via RFM app, no staff needed
- Remote monitoring: live status and fault alerts via RFM
- 100L wet recovery: dirty water contained and not redistributed
- Compact 20-inch deck: navigates aisles as narrow as 32 to 36 inches
Limitations
- Narrower 20-inch deck means more passes on wide-open floors, L4 is more efficient there
- Dry debris requires pre-sweep, wet scrubber only
- Hard floor only, no carpet or restrooms
- Floor drain and 120V outlet required for WS3 workstation
