Unfortunately, the product seems to have a built-in vulnerability, which is extremely annoying.
Despite accurate maintenance and cleaning of the tube being pulled into the drum, the hose can now only partially pull out of the box. All 50cm hooked the hose when pulling firmly and then must be rolled back something to begin this procedure after another 50cm again. Since pulling out of the hose at full hose Läge can sometimes drag on for a few minutes. Meanwhile, I have learned that this problem is not an isolated case.
In addition, the hose box now starting to leak.
After more than 2.5 years and careful nursing an indictment of a brand manufacturer.
