What it does

A heavy scrubber-dryer that services itself, around the clock.

The L50 is the heavy-duty end of the scrubber range, built for large continuous wet floors: supermarkets, shopping centres, arenas, big-format retail and warehouses. It carries the fleet's widest scrub deck (510 mm) and largest tanks (55 L solution, 55 L recovery), so it covers long runs at 2,203 m²/h without stopping every aisle.

The differentiator is the CWS-01 workstation. It automatically refills clean water, drains recovery and recharges, so the L50 runs 24/7 unattended, servicing itself between cycles instead of waiting for staff. An 840 mm squeegee dries the floor behind it, and the 220 RPM disk brush handles the grime a large site builds up overnight.

On-board NVIDIA AI and an automotive-grade 32-beam 3D LiDAR classify obstacles and plan its route in real time, so it shares the floor with shoppers, staff and trolleys rather than needing the place cleared. Day-to-day control, including voice control, runs through the Cenobots app.

Where the L50 earns its keep.

If you wet-mop a large continuous floor every night, the L50's deck, tanks and self-service workstation make it the unit that keeps up.

Supermarkets & grocery

Long aisles and back-of-house scrubbed and dried overnight, ready before doors open.

Shopping centres & malls

Common-area floors and concourses cleaned to a consistent standard across large footprints.

Arenas & venues

Concourses and event floors turned around fast between sessions on big continuous plates.

Warehouses & logistics

Wet-mopping sealed concrete across distribution floors that run long shifts.

Big-format retail

Hardware, trade and large-format stores where the cleaned area is measured in thousands of square metres.

Healthcare & large facilities

Hospital and institutional floors that need consistent, documented wet cleaning at scale.

How it works

Mapped once, then it runs around the clock.

Site survey, a one-off map, then the L50 scrubs to a schedule and services itself at the workstation.

Step 01

Plan

Our engineer scans your site, builds the 3D map and sets cleaning zones, exclusion areas and schedules.

Step 02

Scrub

The L50 follows its path with the deck down, classifying obstacles in real time and drying behind it with the 840 mm squeegee.

Step 03

Dock & service

It returns to the CWS-01 workstation, which refills clean water, drains recovery and recharges, with no staff needed.

Step 04

Repeat 24/7

It resumes where it left off and runs the next cycle, so a large floor stays covered around the clock.

Australian deployment

Big floors, cleaned overnight, on their own.

A WA supermarket, mall or arena floor is thousands of square metres that has to be wet-cleaned and dry before doors open. The L50's 510 mm deck and 55 L tanks are sized for that run, and the 840 mm squeegee leaves the floor walk-ready behind it rather than wet.

The CWS-01 workstation is what makes it practical at scale: the robot refills, drains and recharges itself, so it runs the whole overnight window without a staff member topping up tanks. For a site that already struggles to roster cleaners, that's the difference between a robot that needs minding and one that just runs.

Service distance matters. We're an Australian dealer (Fiction Labs Pty Ltd, trading as Perth Robots) with local engineers, local mapping, and parts on the ground in Perth. For metro deployments we offer same-day on-site response; for regional WA we ship spares overnight and resolve most software issues remotely via the cloud platform.

The L50 is the largest scrubber in the range. For mid-size mixed floors we deploy the L4, for tight occupied spaces the compact L3, and for sweeping or spot-cleaning, the S5 and SP50. Different robot, same partnership, same management dashboard.

Service & support

Australian-based, end-to-end.

No offshore tickets. Perth-based engineers handle survey, deployment, training, mapping changes and incident response.

Mapping & deployment

Site survey, full 3D map, zone and schedule setup, plus CWS-01 workstation siting. We hand over a running system, not a box.

Operator training

On-site session for managers and supervisors. App and dashboard, workstation checks, fault response, escalation flow.

Response SLA

Perth metro: same-day on-site. Regional WA: next business day. Cloud-resolvable issues: under an hour.

Purchase, lease or RaaS

Outright purchase with a Care Plan, 2–4 year lease-to-own, or Robotics-as-a-Service: a fixed monthly fee, all-inclusive.

Why Perth Robots

Honest credibility, not just claims.

Engineering-led.

Built by someone who has engineered advanced systems and operated them in demanding environments — we know what these machines can and can't do.

WA-based service, not a reseller.

We deploy and service every unit ourselves across WA. If a robot's down at 2am on a mine site, that's on us — same time zone.

Multi-OEM, honest advice.

We recommend the right robot for your site, not the only one we carry.

Low-risk by design.

RaaS is a flat monthly subscription, not a capital gamble — the risk sits with us. Run the robot as often as you need.

FAQ

Common buyer questions.

How large a floor can the L50 handle?
It's the heavy-duty scrubber in the range, built for large continuous floors measured in thousands of square metres: supermarkets, malls, arenas, warehouses and big-format retail. It covers 2,203 m²/h with a 510 mm deck and 55 L tanks. For mid-size floors we deploy the L4; for tight spaces, the compact L3.
What makes it able to run 24/7 unattended?
The CWS-01 workstation. When the L50 docks, it automatically refills clean water, drains the recovery tank and recharges, then resumes its run. No staff member has to top up tanks or plug it in, so it can cover a whole overnight window or run around the clock on its own.
How long does it run before it needs servicing?
Up to 6 hours per charge, then a 4 hour charge at the dock. With the CWS-01 workstation handling water and charging automatically, run length is set by the schedule and the floor rather than by how often a person can attend it.
Can it work around shoppers and staff?
Yes. An automotive-grade 32-beam 3D LiDAR, depth camera and bumper let it slow for and steer around people, trolleys and fixtures in a live environment. Most sites run it overnight for full coverage, but it's rated to share the floor during trading hours too.
What floor types does it suit, and does it dry behind it?
Large continuous sealed hard floors: tile, vinyl, sealed and polished concrete and similar. The 220 RPM disk brush scrubs and the 840 mm squeegee dries behind it, so the floor is walk-ready rather than left wet. We confirm the right setup for your surfaces at survey.
How do staff control it day to day?
Through the Cenobots app, including voice control, with start, stop, scheduling and run reports on the dashboard. Site staff get a short induction; we handle mapping, updates and support from Perth.
Is the L50 sold or leased?
Both. Outright purchase with a Care Plan, a 2–4 year lease-to-own, or Robotics-as-a-Service. Subscribe or own from as little as $50 a day, with service, support and software included.

Smaller floor? Different job?

The L50 is the industrial scrubber in a fleet of nine. If your floors are smaller or need sweeping, one of these fits better.
