Roborock Technology and Dreame Technology have brought robot vacuum cleaners with foldable mechanical arms to the annual Consumer Electronics Show in Las Vegas. 

These limbs enable the devices to pick up and move small objects on the floor such as socks and shoes.

Chinese manufacturers have emerged as leaders in the global robot vacuum market. Roborock ranked first with a market share of 16.4%, followed by US producer iRobot at 13.5%. The third to fifth positions were all held by Chinese companies.
