First, turn off the vacuum cleaner and unplug the power plug. Open the dust bag cover of the vacuum cleaner, take out the used dust bag, and dump the garbage into a trash can or bag and bundle it up and throw it away.
Next, check whether there is dust at the vacuum cleaner outlet. If there is, it should be cleaned and the vacuum cleaner filter should be cleaned. These are the prerequisites for a longer service life of the vacuum cleaner.
Finally, open the new dust bag package and install it correctly according to the instructions. Note that the opening of the dust bag should be close to the bottom of the dust bag, and try to buckle the buckle on the vacuum cleaner to ensure that there will be no air leakage after replacement.
