Cleaning Robots / L4
L4Compact productivity for mid-sized commercial environments. The CenoBots L4 is an autonomous scrubber dryer designed for indoor commercial sites that need more capacity than a compact robot, without moving into a large-format cleaning platform.
Model overview
The L4 sits between compact autonomous scrubbers and larger commercial floor-cleaning robots. It is designed for sites that need stronger daily cleaning capacity, while still needing a robot that can operate through corridors, doorways and constrained indoor areas.
Its 38 L solution tank, 450 mm cleaning width and autonomous navigation make it suitable for routine cleaning across mid-sized commercial spaces where manual floor care is repetitive, time-consuming or difficult to complete consistently.
The L4 is a practical option where the site needs more tank capacity and coverage than an entry-level compact robot, but does not require a large ride-on-style autonomous scrubber.
Suitability
The L4 is best suited to indoor commercial sites where the cleaning area is larger or more demanding than a compact robot can comfortably manage, but where access, manoeuvrability and daily usability still matter.
For mid-sized commercial cleaning, the L4 may be a stronger fit than a compact robot. For tighter layouts, Automaate may recommend a smaller model. For larger open sites, Automaate may recommend a higher-capacity autonomous scrubber.
Recommended commercial applications
These are common commercial settings where the L4's 450 mm cleaning width, 38 L solution tank, safety sensing and mid-sized footprint are most relevant.
Useful for trading areas, aisles, back-of-house pathways and shared customer-facing spaces.
Suitable for corridors, shared hard-floor areas and operational zones.
Suitable for hallways, lobby-adjacent areas and service corridors.
Useful for corridors, shared learning areas and multipurpose hard-floor zones.
A practical option for lift lobbies, shared amenities and common hard-floor areas.
Relevant for selected concourses, corridors, amenities and operational zones.
Suitable for civic buildings where cleaning needs to be consistent and controlled.
Feature callouts
Six practical features support the L4's role in mid-sized commercial floor care: compact productivity, ease of use, simplified maintenance, safety sensing, intelligent navigation and water-efficient operation.
The L4 combines a 450 mm cleaning width, 38 L solution tank and 810 mm minimum passable width.
Mobile app task management and remote reports help teams start, monitor and manage routine cleaning.
30-second squeegee blade replacement, a large recovery tank opening and magnetic brush access reduce daily friction.
Multiple sensors and 3D, 360-degree safety protection support safer autonomous operation in live environments.
3D LiDAR, depth camera, bumper sensor and IMU sensing support obstacle awareness and adaptive cleaning.
Water-saving functionality can adjust water flow according to speed, reducing unnecessary water and detergent use.
Servicing and autonomy options
Deploy the L4 as a standalone autonomous scrubber dryer, or pair it with a charging station or workstation to reduce manual charging, refilling and drainage work.
The L4 can be deployed with manual charging, water refill, wastewater emptying and routine operator checks.
Best for: sites with shorter cleaning runs, nearby operators or simpler deployment requirements.
Supports automatic charging. When the robot battery is low, the robot can return, recharge and resume its previous task.
Best for: sites that want automatic charging without full water refill and drainage automation.
Assists with charging, clean water refill, wastewater drainage and detergent filling.
Best for: sites that want to reduce manual servicing and support more automated daily operation.
