Who the CenoBots L50 Is Best For

  • Dense retail stores with narrow aisles: grocery, specialty retail, hardware
  • Multi-zone facilities where one run covers sales floor and back-of-house
  • Hospitals and healthcare: tight corridors, long runs between fills
  • Hotels: covers ballrooms, corridors, lobby, and back-of-house on a single charge
  • Large office complexes with narrow walkways
  • Airport concourses: high area, complex layout, minimal human oversight
  • Manufacturing and distribution with shelving-dense aisles

💡Choose the L50 when you need maximum tank capacity in a compact frame. Choose the L4 when you have open aisles and want the widest scrub deck. The 100L tank means fewer mid-shift interruptions on large facilities.

Why the 100L Tank Matters

The 100-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 100L 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
