Rock Sweeper (Qiji 2404)

About this set

Rock Cleaner is a scene set from KEEPPLEY's Kyanite Squad line, set number 2404 with 149 pieces and a 2/5 difficulty rating, marked 6+. The build centers on a yellow engineering vehicle with black tracked wheels and a mechanical arm grabber, plus two minifigures in blue helmets and a large blue crystal. The yellow, black and blue palette keeps the whole display cohesive. Build the tracked chassis first, then attach the mechanical arm grabber, and finally place the figures and crystal to set the scene; the grabber-to-crystal position is worth adjusting a few times to get a natural look. The main tricky spots are lining up the tracks and securing the arm, but with this part count it stays beginner-friendly. It suits builders who like construction vehicles and want a small scene from a modest number of pieces, or anyone filling out the Kyanite Squad lineup.
