L3

Compact Autonomous Scrubber

CenoBots L3 front view

Automate everyday scrubbing in tight spaces with the L3

The CenoBots L3 is a compact, intelligent floor-cleaning robot designed for fully autonomous cleaning in tight and busy indoor spaces. With powerful scrubbing performance, smart 3D LiDAR navigation and easy app or voice-command control, the L3 delivers consistent, high-quality cleaning with minimal supervision.

Best for

Scrubbing in tight, busy spaces

Primary task

Floor scrubbing and drying in one pass

Environment

Hospitals, retail aisles, grocery stores, offices and other crowded indoor spaces

Deployment type

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

Keep busy indoor floors scrubbed without tying staff to every route

Crowded corridors and aisles need regular scrubbing, but large machines struggle to fit and manual cleaning takes valuable staff time.

Large scrubbers cannot fit tight aisles

Narrow corridors and shop aisles are hard to reach with full-size cleaning machines.

Compact yet productive.

With a pass-through width of only 700 mm, the L3 manoeuvres easily in tight spaces while cleaning edges and corners.

Robots can be hard for frontline staff to operate

Complex screens and menus make operators hesitant to start or change cleaning tasks.

Voice-command operation

Simple voice commands operate the L3 without touching the screen, making day-to-day use more comfortable and accessible.

Sites without plumbing interrupt long cleaning runs

Refilling and emptying tanks by hand adds stops and limits how long the robot can clean.

Water tank & workstation support

An optional mobile water tank and workstation, with a 60 L fresh and 50 L dirty tank, supports long cleaning sessions even without built-in water supply.

Maintenance adds downtime

Changing brushes and emptying tanks can take machines out of service for longer than needed.

Easy maintenance

Magnetic brushes, a quick-release squeegee and an easy-access recovery tank simplify maintenance and reduce downtime.

Key outcomes

Strong cleaning performance

Scrub and dry in a single pass. Dual brushes with ~18 kg brush pressure deliver effective scrubbing on busy floors.

25 L solution tank · 25 L recovery tank · 400 mm cleaning width · 18 kg brush pressure · up to 2,016 m²/h theoretical productivity.

Cleans dramatically faster than manual scrubbing while keeping a compact footprint.

How it works

CenoBots L3

01.

Map or configure

Prepare the L3 for the space and cleaning task. The working environment is mapped and the robot is configured for autonomous cleaning.

What the L3 handles
Uses its 96-beam 3D LiDAR and AI processor for real-time mapping and to 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 L3 carry out the cleaning task autonomously. It scrubs and dries in a single pass, avoiding obstacles in busy spaces, and can be started by voice command.

What the L3 handles
Carries out autonomous scrubbing, obstacle avoidance, path planning and auto-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 with your site. The companion app sends alerts when tasks are complete, while OTA updates keep the software current.

What the L3 handles
Sends task alerts and receives OTA software updates.

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