After wet cleaning, be sure to clean the vacuum cleaner itself. Otherwise, there will be a musty smell. But it takes a maximum of 10 minutes, not difficult. After cleaning, I change the rollers - one dries, the second is ready for the next cleaning. Has some pros: Convenient, 2in1 - really covers all needs. It washes the floor cleanly, there are no problems in order to remove small debris and animal hair. Batteries are enough for the whole apartment - and for wet cleaning and vacuuming the shelves in a dry way. Self cleaning works well. Some cons: For dry cleaning only one narrow brush. There is a desire to have in stock a brush even wider. The vacuum cleaner is quite heavy when lifted entirely. However, when cleaning it is not felt.
