The Crystal sweeper is number six in the Powerminers series. If you move it forward, the titanium sweeper blades will spin. If there is a rock monster or an energy crystal in the way, then the Crystal sweeper will sweep it up and put it into the large bucket in the back. It comes with one Meltrox small red rock monster, one Glaciator small blue rock monster, one rock monster launcher, one Powerminers motorbike, four medium blue energy crystals, four medium red energy crystals, two medium orange energy crystals, one Crystal sweeper vehicle with multi-angle drill and rotating sweeper blades, one Brains minifigure, and one miner minifigure.
