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 of the vacuum cleaner has dropped significantly, we recommend that you check the penetration of the serrated hose between the nozzle and the rod. If a toothpick or other sharp object is stuck in the hose, it gradually becomes coated with dust and clogs the air passage, which significantly reduces the suction efficiency and increases the noise level of the vacuum cleaner. The waste container is secured in position by turning it, see picture of the lock on the container, and its emptying is secured by the flip-up bottom lid. In case of problems with disassembling the filters in the waste container, please do not hesitate to contact our colleagues at
[email protected], they will be happy to help you. Sincerely Sencor. "
