There is an unpleasant odor coming from my VK200 during vacuuming. What can I do about it? Vorwerk International Help Center May 22, 2018 08:30 Please change the filter bag, even if it is not quite full. We also recommend inserting a new Dovina fragrance chip. If the unpleasant odor persists, please clean the appliance's suction channel and motor protection filter. Comments 0 comments Article is closed for comments.
