Hello, thank you for your suggestion, on the basis of which the supplier contacted us and would like to respond below.
"Hello, if the suction power is reduced and the rotary brush does not rotate, it means that the vacuum cleaner is clogged in the flexible hose between the vacuum cleaner head and the waste container. To clean, it is necessary to remove the rotary brush from the nozzle, remove the entire nozzle from the body of the vacuum cleaner and push the hose from one side to the other so that any stuck dirt comes out. In case of any doubts, our colleagues at
[email protected] will help you with the cleaning. Regards Team Sencor"
Please do not hesitate to contact us in case of need. Thank you and have a nice day, Ondřej - Alza expert
