Cleaning the hose from dust and dirt. During operation, the vacuum cleaner can become clogged with dust, dirt, hair and other particles. This causes the hose to become less effective and reduce the power of the vacuum cleaner. To improve the performance of the hose, it is necessary to clean it regularly. This can be done using special attachments or handles that are sold with the vacuum cleaner.
If there are no special attachments, you can clean it using methods at your disposal, for example, as shown in the video.
