4. All parts of the vacuum cleaner shall be tightly connected, especially at the junction of the dust collection part and the power part. The inspection method is: start the power switch, close to the joint with your hand. If there is no feeling of air leakage, the tightness is good, otherwise it is poor. The vacuum cleaner with poor sealing not only has poor dust collection effect, but also consumes a lot of electricity.
