The cleaning effect is better and the rubber main brush does not the hair easily. Our mopping pads are made of super absorbent material that 't leave water stains on the floor or stir up dirt. Dust bags have a good seal design, which effectively prevents dust from leaking and ensures that these particles, once captured, do not re-enter the air. They also have a multi-layer filter system that captures 99.999% of fine dust.
