Smooth rolling design: Adopting a smooth rolling structure design, the friction resistance during travel is smaller, and the machine's pushing and pulling movements are smoother, making daily home cleaning and movement easy and effortless. Flexible and wear-resistant material: Made of high-quality materials with moderate flexibility, it is resistant to friction and wear during reciprocating rotation and sliding on the ground, making it less prone to wear and aging, and prolonging the service life of components. Flexible steering structure: Equipped with a built-in flexible steering structure, it can adapt to various home floor environments such as tiles and wooden floors. The steering is sensitive, smooth, and not stuck, and the whole machine travels smoothly and steadily. Accurate alignment and fitting: It fits tightly to the standard installation dimensions of the body, with simple and easy to assemble and disassemble steps, compatible with multiple models of the same specifications, and saves time and effort in replacing accessories. Designed with a walking structure that fits the ground, the operation sound is soft and not noisy. The whole machine moves smoothly and steadily, reducing the noise caused by ground friction, making it run quieter and more comfortable for home use.
