A Large Format Grocery Store in the Upper Midwest Runs an Autonomous Scrubber After Hours

Floors that never stop being floors

A large format grocery store in the Upper Midwest carries a lot of square footage under one roof. Aisles run long and straight, the sales floor stays busy through the day, and the hard surfaces take a steady beating from carts, spills and foot traffic. Keeping them clean by hand means pulling staff away from stocking and checkout for long stretches.

The floor plan decides how hard the job is. Open layouts with long straight runs and few obstacles suit a machine that follows a fixed route, while every refill stop and tank change breaks up a run. Operators in this position usually want cleaning that finishes its route without a person standing beside the machine.

• A large open sales floor with long straight runs and minimal obstacles
• Cleaning hours that competed with stocking and checkout work
• Route interruptions from refills and tank changes
• A need for cleaning that runs without an operator at the machine

One autonomous scrubber on a large open floor

The store put one autonomous floor scrubber from the robot supplier to work on its open floor. The machine runs autonomously during off hours, which keeps cleaning clear of shoppers and staff. The supplier describes its unit as suited to open format retail and larger grocery, so the floor plan was central to the choice.

A deployment like this rests on measurement before the machine runs a single route. Buyers weighing a similar setup tend to check a short list on their own floor first.

• The narrowest passable route the machine must take
• Stockroom turns and refill points that interrupt a run
• Checkout approaches that narrow the working lane
• Labor hours the machine would displace
• Whether one robot can complete its full route in its operating window

What the supplier reports

The supplier reports that the scrubber cleaned about 644,632 square feet per month across more than 345 autonomous robot hours per month. These figures are the supplier's account of its own operational data.

The supplier also reports labor savings of $5,000 to $6,000 per month, which it says were verified against prior payroll. It describes the freed hours as going to higher value work.

Payback is the supplier's estimate of 9 to 12 months, which it ties to the large open floor plan. Read it as a projection tied to this site's payroll and floor layout.

Where a lease fits this kind of floor

Service Robot Co. is an OEM neutral integrator for US businesses. We select the right robot across manufacturers, then handle finance, deployment, integration, training and service through a nationwide US engineer network, so the customer works with one partner from selection through daily upkeep. For a floor like this one, the selection step decides whether a machine fits the route and the hours the operator needs.

Customers get the robot on a 3 year lease with one fixed payment, quoted after a site assessment. A grocery operator comparing machines can also look at other options. PUDU markets its CC1 Pro Disc to supermarkets and grocery stores, with a dual disc scrubbing design. Tennant's T16AMR was reported by a Dutch logistics operator to cut routine warehouse cleaning labor an estimated 60 to 70 percent about 333 days into a rollout in a 60,000 square meter facility, which is a warehouse result rather than a store one. These are as of the public listings we checked this year.
