After the vacuum cleaner completes its self-cleaning and self-drying process, there will be a voice prompt to remind the user to clean the dirty water tank. Please make sure to clean the dirty water tank periodically, so it would not have any unpleasant odour. It is also highly recommended to air dry the dirty water tank completely after it has been cleaned thoroughly.

 If you have any further questions, please contact MyAnker Support Team for assistance.
