The Space robot-arm trash collector is a trash truck that goes onto different planets and collects waste from them. The robot-arms grab trash and dump it into the trash collector, and the orange brick inside of the collector burns the trash up. The trash collector uses its burnt trash as fuel to power it through space. The space robot arms move when you turn the broom. This LEGO also includes a trash man. In the LEGO, you can also switch out the broom and the broom for the handle to operate the truck. I hope you guys like this LEGO just like I do.
