CLEANING ROBOTS

L4

AI-Powered Scrubber Dryer

Automate scrubbing in crowded spaces with the L4

The CenoBots L4 is a flexible scrubber dryer designed for crowded environments. Powered by an NVIDIA processing chip and AI features, it combines AI-driven stain detection and advanced edge cleaning with a compact design for thorough cleaning in tight spaces, controlled from a 10.1-inch touchscreen or the mobile app.

Best for

Scrubbing crowded commercial floors

Primary task

Floor scrubbing and dirty-water recovery

Environment

Retail, offices, hotels, healthcare, airports and municipal buildings

Deployment type

Mapped autonomous deployment, with SPARK site assessment, training and ongoing support

Keep crowded floors scrubbed without tying people to every repeatable step

Busy commercial and municipal spaces need regular scrubbing around people, furniture and tight aisles.

Crowded aisles are hard to clean with large machines

Tight turns and narrow passages slow down conventional scrubbers.

Compact, manoeuvrable design.

With an 810 mm passage width and 1,100 mm turn-around width, the L4 navigates crowded aisles with ease.

Edges and stains are often missed

Dirt builds up along walls, and stubborn stains need more attention than open floor.

AI stain detection and edge cleaning

AI-driven stain detection and edge cleaning technology let the L4 clean within 0–3 cm of walls.

Refilling and charging interrupt the cleaning process

Each manual stop adds another step before the robot can continue working.

Automatic workstation

The L4 workstation automatically replenishes water and detergent and charges the robot, extending autonomy towards 24/7 operation.

It can be hard to know what has been cleaned

Supervisors may need to walk the floor to confirm routes and completed tasks.

All on your smartphone

The mobile app tracks the robot’s location, plans routes and sends alerts when cleaning is complete.

Key outcomes

Built for crowded spaces

Scrub busy floors with a machine designed to manoeuvre. The L4 combines a compact footprint with strong scrubbing performance.

38 L solution tank · 36 L recovery tank · 450 mm cleaning width · 740 mm squeegee · 20 kg brush pressure · up to 4.5 hrs runtime.

Scrubs and dries in a single pass, dramatically faster than manual cleaning.

AI-Powered
Navigation

Let the L4 handle routes with less hands-on guidance. A safety shield of multiple sensors helps it navigate precisely and avoid obstacles.

32-beam 3D LiDAR · 3D depth cameras · bumper sensor · anti-drop sensors · 360° coverage.

Keeps cleaning reliably around people and changing obstacles.

Intelligent Cleaning Control

Control cleaning with a flick of a finger. The 10.1-inch touchscreen and mobile app make set-up and monitoring simple.

NVIDIA chip with 32 TOPS AI performance · 10.1-inch touchscreen · mobile app · real-time map updates · OTA updates.

Gives supervisors clear visibility over routes, status and completed tasks.

Less routine servicing between cleaning tasks

Automate more of the routine work that keeps the robot ready to clean. The workstation refills and charges the L4 automatically.

Automatic water and detergent replenishment · automatic charging · simple maintenance design.

Reduces manual servicing steps and supports round-the-clock cleaning.

What powers the L4's intelligent scrubbing

Intelligent cleaning

An NVIDIA processing chip with 32 TOPS of AI performance powers stain detection and edge cleaning, with control from a 10.1-inch touchscreen or mobile app.

High cleaning efficiency

A 450 mm cleaning width, 20 kg brush pressure and up to 1,944 m²/h theoretical productivity deliver efficient scrub-and-dry cleaning.

Edge cleaning

Advanced edge cleaning technology cleans within 0–3 cm of walls for thorough results in tight spaces.

Safety shield

A 32-beam 3D LiDAR, 3D depth cameras, bumper and anti-drop sensors combine with CenoBots algorithms for precise navigation and obstacle avoidance.

Autonomous operation

The workstation automatically replenishes water and detergent and charges the robot, extending cleaning autonomy towards 24/7.

Water & energy efficiency

Optional smart water regulation based on floor condition and low energy consumption help optimise operating costs.

How it works

01.

Map or configure

Prepare the L4 for the space and cleaning task. The working environment is mapped and routes are planned in the app or on the touchscreen.

What the L4 handles
Uses its 3D LiDAR and depth cameras to understand the environment and support autonomous operation.

Where people step in
Initial mapping and configuration require human input.
The exact SPARK deployment process TBC

02.

Run the workflow

Let the L4 carry out the cleaning task autonomously. It scrubs and dries in a single pass, detects stains and cleans close to walls.

What the L4 handles
Carries out autonomous scrubbing, edge cleaning, obstacle avoidance and workstation refill and charging.

Where people step in
People step in for situations outside the configured workflow or where manual attention is required. Exact exception and takeover procedures TBC

03.

Monitor and improve

Keep the cleaning workflow aligned as the environment changes. The app shows the robot’s location and status, with real-time map updates and alerts.

What the L4 handles
Supports real-time map updates, status tracking and OTA software updates.

Where people step in
People remain responsible for reviewing performance and deciding when adjustments, maintenance or further configuration are needed. TBC

Deployment and integration

From site survey to launch, SPARK prepares your robot for your site, your workflow and your team.

What SPARK adds

We are not a box shifter. Deployment covers site survey, mapping, workflow design, integration planning, training and launch — so your robot arrives configured for your building rather than dropped at your loading bay.

If the survey shows the robot is wrong for your site, we will say so.

upSPARK and ongoing support

From installation and user training to software updates and on-site maintenance, we provide full after-sales support.

Safety, compliance and governance

Safety, compliance and operating information for technical and procurement review.

Compliance

Certification and conformity

Declaration of Conformity and certification documents for this robot are available on request for technical and procurement review.
