L3
CenoBots
The smartest scrubber-dryer in our portfolio. 128-beam 3D LiDAR and Nvidia AI chip (100 TOPS) for precise navigation in complex environments.
The CenoBots L3 sets new standards in intelligent cleaning. At its core is the 128-beam 3D LiDAR — it captures the environment in three dimensions and enables navigation even in complex layouts, through passages as narrow as 70 cm.
The Nvidia AI chip with 100 TOPS of computing power processes sensor data in real time; smart carpet and cable detection spots the classic robot traps and avoids them safely. For stubborn soiling there is the DeepClean mode: a two-step intensive program that pre-scrubs first, lets the solution work in, and then scrubs and vacuums in a second pass.
With up to 2,016 m² per hour (theoretical) and up to 4 hours of runtime in ECO mode, the L3 handles mid-sized areas efficiently. The optional WS3 workstation takes over charging, water refilling, detergent dosing, and draining automatically — for continuous operation without manual tank logistics.

Why the L3?
The L3 is the right choice for compact, complex environments with high demands on precision: retail, offices, hotels, schools, hospitals.
The 128-beam 3D LiDAR reliably detects even delicate obstacles — shopping trolleys, shelf corners, people. Smart carpet and cable detection means it steers around the classic robot traps without babysitting. With a minimum passage width of just 70 cm, it reaches zones larger scrubbers cannot enter.
Voice commands via the mobile app cover the basic functions, and with the WS3 workstation the L3 runs its cleaning cycles around the clock — including automatic refilling, detergent dosing, and draining. With our full-service model, we handle maintenance and optimal configuration — you get a clean floor.

What do the numbers mean?
The L3's numbers in practice: 2,016 m²/h is the theoretical maximum (400 mm width × 1.4 m/s) — in real layouts with obstacles and turns, plan for a fraction of that; a 3,000 m² supermarket is a relaxed overnight job. The 400 mm scrubbing width with dual disc brushes and 18 kg contact pressure delivers intensive deep cleaning in a compact format. The 25-litre on-board tanks match that format, and the optional WT3 mobile water tank (60 litres fresh water, 50 litres waste water) supplies the workstation for multiple cleaning cycles without manual intervention — or a plumbed WS3 connection removes tank logistics entirely.
The Nvidia AI chip delivers 100 TOPS of edge computing power for real-time sensor processing. And with 1.5–2 hours of charging and automatic resumption, the L3 with its workstation can work through an entire night shift.
FAQ
Frequently asked questions about the L3
The WS3 workstation handles four tasks fully automatically: 1) Charging the battery (1.5–2 hours to 100%). 2) Refilling fresh water. 3) Dosing cleaning agent at the correct concentration. 4) Draining waste water. Water supply comes either from a fixed plumbing connection or — where none is available — from the optional 60-litre WT3 mobile water tank, which you top up occasionally. The rest runs autonomously.
For heavily soiled floors, the L3 has a dedicated DeepClean mode: a two-step intensive program that first pre-scrubs the area with the squeegee raised so the solution can work in, then scrubs and vacuums in a second pass — the manufacturer's recommended approach for stubborn stains. Zones that regularly need it, such as entrance areas or checkout lines, we configure into the cleaning plan during setup.
Yes — voice commands are given through the mobile app and cover the basic functions such as starting, stopping, and returning to the station. There is also a follow-me mode: the robot follows a staff member, which the manufacturer positions for effortless mapping and for moving the machine between areas — not as a cleaning mode. Day to day, most clients simply run scheduled cleaning plans plus the app.
The L3 is a compact-format machine: the manufacturer positions it for retail, offices, hotels, schools, and hospitals — realistically areas up to roughly 3,000 m². The workstation shows its strengths particularly with daily use — the more frequently the robot operates, the more time the automatic refilling and draining saves. For large, open halls, the L50 is the better fit.
