Walmart Inc.'s warehouse division Sam's Club is adding 372 floor-scrubbing robots to its fleet, putting the devices in all 599 U.S. clubs. Sam's Club is also expanding a pilot program to test shelf inventory technology that can be added to the robots. A Sam's Club spokeswoman said Thursday that the floor cleaners will give employees more time to focus on serving club members. Walmart stores use the same autonomous floor scrubbers that are powered by an operating system developed by Brain Corp. and made by Tennant Co. Walmart said in late 2018 it was adding 360 of the robots to an initial 100 used in a pilot program. In April 2019, the Bentonville-based retailer said it would have the floor cleaners in 1,860 stores by the following February.

Schnuck Markets plans another robot rollout, this time to aid in store maintenance. San Diego-based Brain Corp., said Wednesday that its artificial intelligence (AI) technology will power Tennant Corp. floor-scrubbing robots to be deployed at more than half of Schnucks stores by the end of the year. The St. Louis-based grocer operates 112 supermarkets in Missouri, Illinois, Indiana and Wisconsin.
