Upper Midwest Retail Floor Care Moves to an Autonomous Scrubber: A Case Study

Floors that never stopped taking traffic

A large-format retail store in the upper Midwest runs a broad sales floor where shoppers, carts and spills arrive all day. Keeping hundreds of thousands of square feet presentable meant a floor care routine that competed with customers for the same aisles and the same staff hours.

Manual scrubbing at this scale is slow work. A walk behind machine needs an operator for every pass, stops for tank changes, and sits idle whenever that operator is pulled to other duties. Coverage ends up depending on who happens to be on shift.

The store wanted floor care that ran on a schedule rather than on availability, with the cleaning hours handed back to the people already on payroll.

A scrubber that works the open floor after hours

The deployment began with a survey of the floor plan. The integrator's read was that a large, open layout suits an autonomous scrubber well, since the machine can hold long, straight routes with few interruptions.

One autonomous scrubber was assigned to the hard floors and run on a set schedule. The robot took over the repetitive passes, and the human role shifted toward setup, oversight and exception handling.

Robots of this class still leave work for people. One buyer's guide describes a model in which a person still handles setup, tank service, edges and exceptions, often 45 to 60 minutes a shift. Planning for that time was part of the rollout, not an afterthought.

• Survey the floor plan and mark routes, obstacles and edges
• Train staff on setup, tank service and daily checks
• Run the scrubber on a fixed schedule and log its hours
• Compare coverage and payroll against the prior baseline

Measured output and what the payroll comparison shows

In the period reported, the scrubber covered about 644,632 square feet per month and logged more than 345 autonomous hours in the same span. The integrator frames those hours as roughly the work of two full time employees, a comparison drawn from its own reporting rather than a headcount audit.

The integrator reports labor savings of $5,000 to $6,000 per month, verified against the store's prior payroll. These are the figures the integrator gives for this site, and they are best read as one operator's reported result.

The integrator estimates a payback of 9 to 12 months for this site. That is its estimate, not a guaranteed return, and it notes the figure runs shorter than its standard estimate because of the large open floor plan.

Savings hold only when the freed hours are cut or redeployed. The payroll effect depends on what the store does with the time it gets back, and that choice belongs to the operator.

What a leased scrubber program looks like for a floor like this

Service Robot Co. is a full service, OEM neutral commercial robot 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. For a floor like this one, that means matching the machine to the floor first.

We lease robots only, through financing on a three year lease with one fixed payment quoted after a site assessment. Leasing generally requires little or no upfront capital, which is why many operators look at a monthly payment program before weighing a larger commitment. The site assessment is where the numbers get built: floor area, open versus cluttered zones, the schedule and the hours the team would actually redeploy.
