Robots can now be seen roaming the aisles of some Long Island Stop & Shops.

The store says Marty the robot is used to identify floor hazards, like spills, and to alert staff that cleanups are needed.

The robot stands 6’8” tall and rolls around the store, using cameras to monitor the aisles.

A sticker on the side of the robot explains its purpose.

But some customers wonder if they are being spied on.

Stop & Shop says the robots are not replacing employees.
