L50

Autonomous Scrubber Dryer

Automate routine floor scrubbing with the L50

The CenoBots L50 is an autonomous scrubber dryer for commercial, industrial and municipal environments. It handles routine floor scrubbing on mapped routes, while teams can set cleaning tasks and view reports through the app. An optional workstation can automate charging, clean-water refilling and wastewater drainage.

Best for

Large-area floor scrubbing

Primary task

Floor scrubbing and dirty-water recovery

Environment

Retail, offices, hotels, healthcare, warehouses, factories, airports and schools

Deployment type

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

Keep large-area floor cleaning moving without tying people to every repeatable step

Large commercial, industrial and municipal floor areas need regular scrubbing across recurring zones and routes.

Routine floor scrubbing keeps staff tied to the same routes

Large areas need to be cleaned again and again, using valuable time on repetitive work.

Autonomous mapped scrubbing.

The L50 carries out configured floor-cleaning tasks autonomously across mapped areas.

It can be hard to know what has been cleaned without checking manually

Supervisors may need to walk the floor or follow up with staff to confirm which tasks have been scheduled and completed.

App-based task management and reporting

Teams can set cleaning tasks and view cleaning reports through the app, making it easier to keep track of cleaning activity.

Charging, refilling and draining can interrupt the cleaning process

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

Optional workstation automation

With the CWS-01 workstation, charging, clean-water refilling and wastewater drainage can be handled automatically.

Edges and stubborn marks often need extra attention

Open floor areas may be straightforward to scrub, while edges and tougher dirt can require more focused cleaning.

Edge cleaning and DeepClean

The L50 can clean within 50 mm of edges and offers DeepClean, a two-stage mode for more stubborn soiling.

Key outcomes

Built for larger-area cleaning

Cover substantial floor areas with a cleaning system designed for longer, high-capacity scrubbing tasks. The L50 combines a large solution capacity, wide cleaning path and sustained runtime for demanding commercial and industrial environments.

55 L solution tank · 55 L recovery tank · 510 mm cleaning width · 25 kg brush pressure · up to 6 hrs runtime · up to 2,570 m²/hr theoretical productivity.

Supports larger cleaning runs and high-volume routine floor scrubbing without relying on a small-capacity machine.

Smarter Autonomous
Navigation

Let the L50 handle mapped cleaning routes with less hands-on guidance. Its sensing and AI hardware help it understand its surroundings, navigate autonomously and adapt its map when the environment changes.

Automotive-grade 32-beam 3D LiDAR · 3D depth camera · bumper sensor · IMU sensor · NVIDIA AI chip with up to 100 TOPS · automatic map adaptation.

Reduces the need for operators to continuously guide the machine through repeatable cleaning routes and helps the robot adapt when its working environment changes.

Easier Cleaning Oversight

Set cleaning tasks and check cleaning activity without always being beside the robot. Teams can manage tasks and review cleaning reports through the mobile app, while software can be updated remotely through OTA updates.

Mobile app task setting · remote cleaning reports · automatic map adaptation · free OTA software updates.

Gives supervisors easier visibility over cleaning activity and reduces the need for on-site intervention for routine software updates.

Less routine servicing between cleaning tasks

“Automate more of the routine work that keeps the robot ready to clean. With the optional CWS-01 workstation, the L50 can handle charging and water management automatically.

Automatic charging · clean-water refilling · wastewater drainage · detergent filling through the CWS-01 workstation.

Reduces routine manual servicing steps and helps keep longer cleaning workflows moving with less operator intervention.

What powers the L50's large-scale autonomous cleaning

Superior cleaning productivity and performance

The L50 delivers powerful, efficient cleaning with a 55 L water tank, 120Ah battery, and high pad pressure for thorough cleaning. With productivity of up to 2,570 m² per hour, it efficiently covers large commercial spaces.

Built to last

The L50 is built for long-term reliability, using a durable rotational molding process and proven components. Thoroughly tested to withstand wear and tear, it ensures reliable performance over time.

Human-like intelligent cleaning

The L50 uses advanced 32-beam 3D LiDAR and AI computing for intelligent, human-like cleaning. It cleans within 5 cm of walls and adapts its mapping to optimize routes and improve efficiency.

High level of safety

Equipped with multiple sensors and a three-dimensional, 360-degree comprehensive safety protection system, this scrubber offers a high level of safety during autonomous cleaning operations.

Hassle-free after sale service

The L50 adapts to environmental changes autonomously using advanced mapping and algorithms. Free OTA updates keep its software up to date without requiring on-site technician visits, ensuring reliable, efficient cleaning.

Easy to maintain

The L50 is easy to maintain with its one-stop docking station for automatic water refilling, draining, and charging. Its modular components and intuitive design simplify maintenance and troubleshooting.

How it works

01.

Map or configure

Prepare the L50 for the space and cleaning task. The working environment is mapped and the robot is configured for autonomous cleaning.

What the L50 handles
Uses its mapping and sensing capabilities 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 L50 carry out the cleaning task autonomously. Once configured, it follows the cleaning workflow and navigates the mapped environment while scrubbing the floor.

What the L50 handles
Carries out autonomous floor cleaning using its onboard navigation, perception and cleaning systems.

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 L50 can adapt its map as conditions change, while OTA software updates help keep the system current.

What the L50 handles
Supports automatic map adaptation and free OTA software updates.

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