cloth slightly dampened with soapy water. Do not
use chemicals which can melt plastic, such as
gasoline, thinner, benzine and kerosene.
When suction power of the cleaner becomes weak
due to soiled dust bag, wash the dust bag with soapy
water by hands and let it dry completely before using
it again.
