A container-handling vehicle for picking up storage containers from a three-dimensional grid of an underlying storage system includes a first set of wheels arranged at opposite sides of a vehicle body, for moving the vehicle along a first direction on the grid; a second set of wheels arranged at opposite sides of the vehicle body, for moving the vehicle along a second direction on the grid, the second direction being perpendicular to the first direction; and the first set of wheels displaceable in a vertical direction between a first position, wherein the first set of wheels allow movement of the vehicle along the first direction, and a second position, wherein the second set of wheels allow movement of the vehicle along the second direction. The vehicle body surrounds a cavity within which at least a first lifting device and a second lifting device are positioned adjacent to each other, each lifting device is arranged to lift a storage container from the grid and into the cavity, such that a bottom of the storage container is at a level above the lowest level of the second set of wheels.
