One robot, six zones, two quiet windows — and a cleaning team that got its nights back.

The setting

A large hospital with a ground-floor public area of roughly 9,600 sqm — lobbies, corridors, waiting areas, and connecting walkways. High foot traffic during the day, and a hygiene standard that doesn't allow for "good enough."

The challenge

Deep-cleaning that area every week meant pulling staff from other duties, paying overtime, and accepting a quality level that depended on how tired the night team was.

The facility wanted three things: a consistent clean, no disruption to patients, and no additional headcount.

The approach

The facility divided the 9,600 sqm area into six zones and deployed a single C2 cleaning robot.

Using the Allybot app, the team scheduled a weekly deep-scrub task across two low-traffic windows:

5:30–8:00 AM

12:00–3:00 AM

The C2 handles the route autonomously, using a multi-sensor stack (LiDAR, IMU, ultrasonic, and structured-light cameras) to avoid people and obstacles. When the battery runs low, it returns to its dock and recharges without operator involvement.

The deployment

Setup followed four steps: activate the unit and connect it to the Allybot app, record and save a map of the floor, mark no-go and passable zones, then configure the cleaning task and schedule.

No floor markers, no ceiling modifications, no building work.

Why one unit was enough

The C2 combines scrubbing, dust-mopping, and vacuuming in a single pass. Instead of maintaining three machines and three schedules, the facility maintains one — which is also how a single unit covers the full area within two quiet windows.

The results

One robot covers the full 9,600 sqm area

Deep cleaning happens in off-hours windows, with no disruption to patients or staff

Staff involvement is limited to two actions: filling the clean-water tank and emptying the wastewater tank

Cleaning efficiency of 300–800 sqm per hour, with 5–12 hours of runtime per charge

No new night shift. No standing overtime line. A floor that is consistently clean before the first patient arrives.

What it suggests for other facilities

The lesson isn't "buy a robot." It's that large, repetitive, after-hours floor care is one of the clearest places to start — measurable area, predictable schedule, and a task that doesn't require a person to make judgment calls.
