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 has decreased since you first bought the vacuum cleaner, we recommend that you clean and check the flow of air through the hose that runs from the vacuum cleaner head (behind the rotating brush) to the dust container. A larger piece of debris may have become lodged in the hose, which has subsequently become coated in dust and is now restricting the airflow. This significantly reduces the vacuum cleaner’s suction power and increases its noise level. If you are unsure how to carry out the cleaning, please do not hesitate to contact our team at
[email protected]. Regards Team Sencor"
Please do not hesitate to contact us in case of need. Thank you and have a nice day, Ondřej - Alza expert
