Warm Tips: Please wash the filter and dry after use, so the next use would remain the strong suction. If the vacuum suction becomes weak or suddenly stops working, it may be the filter is clogged, please clean the filter in time. If the Baseus car vacuum suddenly stop working, may due to the overheat protection mode. Please turn off the vacuum and turn it on after minutes. We are love to help when you have any problem with Baseus products.
