Exciting may be in the eye of the beholder.

Marty has just one job: The robot moves around the store and when it encounters a spill or a loose item on the floor, it alerts the staff to come clean it up using the PA system. That’s it. That’s all. What’s worse is that Stop & Shop employees say the robot can’t even do that well.

“Today [Marty] called for cleanup because it detected something on the floor,” one Stop & Shop employee told New Food Economy. “The ‘something’ was someone’s cart. It will stop for anything it detects on the floor, even a twist-tie from produce, and someone has to go pick it up or the robot will keep announcing the need for a cleanup.”

“It’s really not doing much of anything besides getting in the way,” said Kristen. She complained that the robot pages the store nearly constantly, over the smallest things—like a stem from a bunch of grapes—and it will go around in circles until an employee comes to clean the “hazard” up. “Right now he’s a glorified Roomba and he doesn’t even vacuum.”

Stop & Shop’s official line on the worker-robot tension, shared with concerned customers on Twitter and reiterated by Brogan to New Food Economy, is that Marty frees associates to spend more time with customers. Also, Marty supposedly can’t be meant to replace workers because he “doesn’t even do the clean-up.”

Brogan also told New Food Economy that the company has no plans to expand Marty’s responsibilities. But Kristen said the managers at her store have already informed employees that they eventually want the robot to scan shelves to look for out-of-stock items and price disparities, something the robot is already programmed to do. (Tim Rowland, the CEO of Badger Technologies, the company that manufactures Marty, has further described the robots’ capabilities.)
