During use, the dirty water tank, brushes and lower parts of the cleaner will ultimately get dirty as they come into contact with the water being extracted from the carpets. To keep your cleaner working efficiently it is a good idea to give the product a good clean after each use. Wash the water tank, brushes , filters and lower parts of the main body of the cleaner with warm water. This will remove dirt, carpet fibres and debris that have been washed out of the carpets. Allow everything to dry thoroughly before assembling the cleaner.
