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 the largest tank capacity (55L / 14.5 gal) for large facilities with fewer refills. Choose the L4 when floor space is tighter — the narrower 17.7-inch deck (31.9in passable) handles tighter aisles than the L50 at 35-36in passable width.

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

Frequently Asked Questions

Common questions facility teams ask while evaluating autonomous floor scrubber ROI, pricing, and deployment fit.

How much does the CenoBots L50 cost?

The CenoBots L50 MSRP is $41,820. With the CWS-01 workstation (MSRP $4,667), budget approximately $46,500 for a fully autonomous deployment. RaaS: $1,650/mo (36-month) or $2,300/mo (24-month).

What is the CenoBots L50 coverage area?

The L50 has a 55-liter solution tank, the largest in the CenoBots lineup, allowing coverage of approximately 40,000 to 60,000 sq ft per charge without manual refilling.

What is the difference between CenoBots L50 and L4?

L4: 17.7-inch scrub deck, 75L tank, best for open mid-size facilities. L50: 20.1-inch compact deck, 55L tank, designed for dense multi-zone facilities where a larger machine cannot maneuver.

Does the CenoBots L50 work in narrow aisles?

Yes. The L50 compact 20.1-inch scrub deck navigates aisles as narrow as 35 to 36 inches while carrying the largest solution tank in the lineup.

Is the CenoBots L50 suitable for grocery stores?

The L50 is ideal for grocery stores with dense end-cap configurations, narrow specialty aisles, or mixed retail and storage layouts. The 55L tank means no mid-run tank refill for facilities up to 55,000 sq ft.
