What it does

A compact scrubber-dryer that cleans during the day, around people.

The L3 is the compact, daytime-friendly scrubber-dryer for offices, clinics, hotels and retail corridors. It wet-scrubs and dries sealed hard floors on a schedule you set, quietly enough (≥64 dB(A)) to run while staff and customers are about. No supervision required.

At 400 mm wide with a 700 mm pass-through, it goes where larger machines can't: between desk pods, around reception furniture, down clinic corridors and into edges and corners. It carries 25 L of solution and 25 L of recovery, and deploys plumbing-free through a mobile water tank and workstation, so a site with no easy water access is no barrier.

On-board NVIDIA AI and a 96-beam 3D LiDAR classify obstacles and plan its path in real time, including small, low hazards like cables and temporary carpets that trip up basic sensors. It maps your site once, then adapts to the day-to-day clutter of a working floor. Day-to-day control, including voice control, runs through the Cenobots app.

Capabilities

What it does, in motion.

Short, silent loops: a daily scrub, smart carpet detection, edge cleaning and tight-space manoeuvring.

Daily scrub

Wet-scrubs and dries sealed hard floors in a single pass, leaving them walk-ready.

Smart carpet detection

Recognises temporary carpets and mats and cleans around them, protecting floor coverings.

Edge & corner cleaning

Tracks tight to walls and into corners, leaving less for a person to finish by hand.

Tight-space manoeuvring

Turns and threads through crowded aisles and furniture in a 700 mm pass-through.

Best for

Where the L3 earns its keep.

If you clean mixed indoor hard floors during the day, around people, the L3 fits where bigger machines don't.

Offices & workplaces

Lobbies, breakout areas and desk-pod aisles cleaned during occupied hours without closing a floor off.

Healthcare & aged care

Clinic corridors, waiting rooms and ward circulation, cleaned quietly around patients and staff.

Hotels & hospitality

Front-of-house corridors, foyers and back-of-house circulation kept presentable through service.

Retail & boutique floors

Shopfront aisles, fitting-room corridors and tight retail floors that bigger scrubbers can't enter.

Schools & education

Hallways, libraries and admin areas on mixed hard floors, scheduled around class timetables.

Mining-camp accommodation

Donga corridors, ablution blocks and mess areas, deployed plumbing-free where there's no fitted water.

How it works

Mapped once, then it runs itself.

Site survey, a one-off map, then the L3 scrubs to a schedule. The dashboard tracks coverage and flags refills.

Step 01

Plan

Our engineer scans your site, builds the 3D map and sets cleaning zones, exclusion areas and schedules. One short visit for most sites.

Step 02

Scrub

The L3 follows its path with the brush down, classifying obstacles in real time, avoiding cables and temporary carpets, and cleaning into edges and corners.

Step 03

Charge

At low battery, or end of cycle, it returns to the dock for a 1.5 to 2 hour recharge and resumes where it left off. No human in the loop.

Step 04

Refill

The workstation refills clean water and drains recovery; staff top up or empty when the dashboard flags it. Quick-release access keeps it to minutes.

Australian deployment

Built for occupied floors, not after-hours only.

WA workplaces and care facilities need floors cleaned during occupied hours, not just overnight. The L3's quiet ≥64 dB(A) operation and 700 mm footprint let it work around staff, patients and customers without closing an area off, so cleaning stops competing with the working day.

Plumbing-free deployment is the regional advantage. With a mobile water tank and workstation, the L3 runs in mining-camp dongas, ablution blocks and remote offices that have no fitted floor-cleaning plumbing. It refills and drains at the workstation rather than a tap and floor waste.

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 L3 is the compact end of the range. For large continuous wet floors we deploy the L50; for busy public floors where dirt is localised, the SP50 spot cleaner. 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. We hand over a running system, not a box.

Operator training

On-site session for managers and supervisors. App and dashboard, refills, 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.

Can the L3 run during the day, around staff and customers?
Yes. It's a quiet (≥64 dB(A)) compact scrubber built for daytime work in offices, clinics and corridors. The 96-beam 3D LiDAR and depth camera let it slow for and steer around people, trolleys and furniture, so it shares the floor rather than needing it cleared.
How tight a space can it clean?
It passes through a 700 mm gap and scrubs a 400 mm path, so it works crowded aisles, reception areas and corridors that larger machines can't enter. It also cleans into edges and corners rather than leaving a wide untouched margin.
We don't have easy water access. Can we still use it?
Yes. The L3 deploys plumbing-free: a mobile water tank and workstation handle fill and drain, so it suits sites with no fixed plumbing, including mining-camp dongas and ablution blocks. It carries 25 L of solution and 25 L of recovery.
Will it get tangled in cables or damage temporary carpets?
Its intelligent small-object detection picks up low hazards like cables and temporary carpets, not just standard obstacles, so it avoids entanglement and protects the premises. It maps the site once, then adapts to day-to-day changes.
How long does it run, and what's the maintenance like?
Up to four hours per charge in ECO mode, then a 1.5 to 2 hour recharge. Maintenance is fast and low-downtime: magnetic brushes, a quick-release squeegee and easy recovery-tank access mean swaps take minutes, not a service call.
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 L3 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.

Bigger floor? Bigger robot.

The L3 is the compact scrubber in a fleet of nine. If your floors are larger, mixed or public, one of these fits better.
