The design concept of Little Loli is "easy clean", cute and delicate. The whole machine's design adopts a variety of methods such as geometric addition and subtraction, gradation, and so on. The track-shaped handle runs through the battery, motor, and dust cup to the suction part, demonstrating the style of simplicity. The diamond-shaped air outlets on both sides make the wind tangible. The downwardly tilted handle looks playful and straightforward. The design of the small window allows users to see the dust inside.
