Beach cleaning machines work by collecting sand by way of a scoop or drag mechanism and then raking or sifting anything large enough to be considered foreign matter, including sticks, stones, litter and other items.
For example: In Galveston, Texas, low oxygen levels in the water resulted in thousands of dead fish washing ashore.
[3] The cleanup after the Deepwater Horizon oil spill saw large applications of sand cleaners to the area.

For example, a smaller 4-wheel and halftrack sand cleaning machine is used for sandpits in kindergarten and municipality playing fields and for beach volleyball.
