BONNEY LAKE, Washington: When an autonomous floor scrubber was rolled out in Walmart’s Bonney Lake store last month, shoppers mistook the teal blue scrubber zipping down the aisles for a runaway machine, said manager David Klein. "Some customers are a little freaked out."
Klein said the Auto-C robot has relieved his employees of several hours of cleaning every evening, and has allowed him to avoid hiring another maintenance worker on the previously understaffed team. The 4ft-tall scrubber, which resembles a riding lawn mower but is considerably quieter, uses sensors to scan its environment and to avoid people or objects in its way.
