Australian Shopping Centers Free Five to Six Nightly Scrubbing Hours per Robot

The nightly scrubbing load

An Australian shopping-center operator running 15 autonomous scrubbers across eight centers started from a familiar problem. Every night, cleaning teams pushed industrial scrubbers over large concourses, and that work tied up staff for hours before the centers opened.

The routine was also multi-step in the sense that matters on the floor. Teams typically swept, scrubbed and then burnished, one pass after another. Each step asked for labor and time, and the sequence left less room for the detailed work that high-touch surfaces needed across the malls.

The operator also took a forward leaning stance on new technology. It pushed for a relatively quick mass deployment rather than a slow, cautious trickle, and it wanted the hours freed by the machines to go toward hygiene work.

• Nightly scrubbing with industrial machines occupied staff for hours each night
• Sweep, scrub and burnish was a three-step routine on every floor
• High-touch surface sanitizing needed more attention across all eight centers

A quick mass deployment with learning on the job

In 2017 the operator bought and deployed fifteen autonomous floor scrubbers from the robot supplier, spread across eight premier shopping center locations. The rollout was broad and fast, and it reached every one of the eight centers.

The operator learned on the job. Its teams gained practical insight into putting the scrubbers to their best use, and those lessons shaped how the fleet ran from one night to the next.

Remote monitoring came through the supplier's web software, which reports productivity metrics and sector-level coverage maps. Supervisors could see how each zone was covered without walking every aisle.

Floor finish changed as well. A scrubbing pad used with the robots gradually approaches burnish-quality results, which removed the separate burnish pass the cleaning team had always performed.

The fleet has since been kept running under a vendor maintenance pack that provides local support, regular upkeep and on-site service when needed.

• Purchase and deploy 15 autonomous floor scrubbers across eight centers in 2017
• Run a quick mass deployment, with staff learning the routines on the job
• Monitor productivity and coverage remotely through the supplier's web software
• Use a scrubbing pad that removes the separate burnish step
• Keep the fleet on a vendor maintenance pack with local support and on-site service

What the operator reported

The headline figure belongs to the robot supplier. According to the vendor, a single unit can free cleaning staff from the five to six hours otherwise spent running an industrial scrubber every night. This is a vendor-reported figure for one unit.

The freed time did not simply become idle time. The supplier says team members moved on to more detailed sanitizing of high-touch surfaces throughout the malls, so the labor shifted toward hygiene work rather than away from the floor.

On cost, the supplier says that augmenting cleaning teams with the scrubbers has helped the operator reduce cleaning costs. That effect is described in general terms only.

Productivity and coverage data came from the same remote monitoring that managed the fleet, which gave the operator a running view of the work each night.

What a night shift scrubber program looks like for a US business

Service Robot Co. is a full-service, OEM-neutral integrator for US businesses. We select the right robots across manufacturers, then finance, deploy, integrate, train and service every unit through a nationwide US engineer network. One vendor covers the whole lifecycle, so a facility manager does not have to coordinate a robot maker, a financier and a separate service crew.

For a shopping center or any large floor, the questions are the ones this operator answered: how many scrubbers, which zones run overnight, how staff are retrained for higher-touch work, and who keeps the fleet running. Service Robot Co. leases robots only, through a 3-year lease with one fixed payment quoted after a site assessment. That gives a site a fixed number to plan around.

This deployment was run by its own operator with the robot supplier, not by Service Robot Co. It is a real example we study, and the hours cited are the supplier's own figures.
