For convenience, you need to buy replaceable elements: brushes and a rag, filters, they need to be removed and washed and dried. While one set is drying, the second can be inserted. Got pros: Perfectly cleans odnushku in a new building. Previously, dust constantly appeared on the floor every day and every day it bothers to clean up. The vacuum cleaner copes with this perfectly, it starts automatically 2 times a day and everything is always clean. Has some cons: For a very long time I connected it with the Wi-Fi application, but connected it.
