Replacing the vacuum cleaner, the dust box and the dust cup of the sweeping robot regularly can avoid the dust accumulation and agglomeration on the inner wall to block the air duct, keep the suction of the machine stable and not decay, and the cleaning effect of the whole house is always the same. Replacing dust-collecting fittings has a higher sealing fit, so as to prevent dust leakage and dust from gaps, prevent fine dirt from floating twice, and protect indoor cleanliness. The dust box that has been used for a long time is easy to age, deform and crack. Changing it in time can prevent dust from infiltrating into the internal movement of the machine, reduce circuit faults and effectively prolong the overall service life of the equipment. Replace the matching dust box and dust cup with accurate mounting buckle, which is easy to disassemble and clean, without complicated debugging, and has strong versatility for all kinds of sweeping robots and vacuum cleaners. The aging dust box is easy to cause poor air intake in the air duct. After replacement, the air circulation is smooth, which reduces the running load of the motor, reduces the working noise and saves electricity and energy.
