CenoBots · Edge-Cleaning Autonomous Floor Scrubber
L4 — Cleans to the Edge, Not Near It
The CenoBots L4 is a mid-size autonomous robot floor scrubber built for busy commercial and public facilities. Intelligent navigation, close-to-edge cleaning within 3 cm of walls, and a maintenance-friendly workstation deliver consistent performance shift after shift.

Why L4
Balanced size, high productivity, and cleaning right up to the wall.
Close-to-Edge Cleaning
Advanced localisation lets the L4 scrub to within 3 cm (1.2 in) of wall surfaces, removing the uncleaned strip along walls and skirting that conventional scrubbers leave behind for manual mopping.
Balanced Size, High Productivity
An 810 mm minimum passage width and 1,100 mm turning width let the L4 work aisles, corridors, and constrained spaces, while the 450 mm cleaning path and 38 L solution tank keep throughput high.
AI Stain Perception
An NVIDIA computing platform delivering 32 TOPS drives AI-enabled perception that recognises stains on the floor, so the robot can concentrate cleaning effort where it is actually needed.
Comprehensive Safety System
32-beam 3D LiDAR with a 150 m (492 ft) detection range, 3D depth cameras, and bumper sensors combine with CenoBots algorithms to handle protruding objects, low obstacles, and cliff detection safely.
10.1" Touchscreen & Mobile App
Operators manage tasks from the on-board 10.1-inch touchscreen or the mobile app — tracking the robot's live location, planning cleaning routes, reviewing performance data, and receiving task-completion alerts.
4-in-1 Workstation
The optional workstation automates charging, clean-water refilling, wastewater draining, and detergent refilling in a single dock, supporting long autonomous cycles with minimal manual handling.
Automatic Map Update & OTA
The L4 detects environmental changes and updates its own map without a technician re-mapping the site, and receives new features over the air. Intelligent troubleshooting and 30-second squeegee replacement keep downtime low.
Smart Flow Sustainability
Solution flow is adjusted automatically to cleaning speed, reducing unnecessary water and detergent consumption while holding cleaning performance steady.

Where L4 Works
Proven across these industries — talk to us about yours.
Retail & Shopping Centres
Mall concourses and store floors where cleaning right up to shopfronts, columns, and skirting removes the manual mop-up pass.
Airports & Transport Hubs
Concourses and gate areas that need continuous scrubbing around glass walls, seating, and moving crowds.
Hospitals & Aged Care
Corridors and public areas cleaned safely alongside patients, staff, and equipment with full cliff and obstacle protection.
Offices & Education
Foyers, atriums, and campus buildings on a 24/7 workstation cycle with automatic charging, refilling, and draining.
About CenoBots
CenoBots is a leading international robotics company specialising in the cleaning industry, with subsidiaries in Singapore, the USA, the Netherlands, and China. The company builds intelligent, reliable, hassle-free cleaning robots that are now deployed across more than 30 countries worldwide.
Why CenoBots
CenoBots builds to a simple principle — "Clean Like a Pro". Every robot pairs an NVIDIA AI computing platform with 3D LiDAR and multi-sensor fusion, so it can detect glass doors, protruding objects, cables, and moving forklifts that defeat conventional 2D-LiDAR machines. Automatic map updating means the robot re-learns a changed floor plan on its own, without a technician re-mapping the site. Advanced localisation lets the scrubbers clean to within a few centimetres of walls, and AI spot-cleaning targets only the areas that are actually dirty — lifting effective throughput dramatically while cutting water, detergent, and power use. The range spans compact scrubbers for hospitals and schools, heavy-duty scrubbers for warehouses, an industrial sweeper for factories, and the SP50 AI spot-cleaning vacuum.

FAQs
Common questions about the L4 from Australian operators.
How close to the wall can the L4 actually clean?
Within 3 cm (1.2 in) of wall surfaces. CenoBots' localisation algorithm reduces sensor noise and improves positioning accuracy, enabling near-zero-distance edge cleaning.
Does it need a person to refill and empty it?
Not with the 4-in-1 workstation. The dock automates charging, clean-water refilling, wastewater draining, and detergent refilling, so the L4 can run long autonomous cycles unattended.
What happens when the floor plan changes?
The L4 detects environmental changes with its 3D LiDAR and perception algorithms and updates its map automatically — no technician re-mapping required.
How does the L4 differ from the L50?
The L4 is the mid-size scrubber with a 450 mm cleaning width, 38 L tank, and 810 mm passage width. The L50 is the heavy-duty model with a 510 mm cleaning width, 55 L tank, and up to 6 hours of runtime for large warehouse and logistics floors.
