Set the SFD20 as flexible lengthened "centrally positioned sawed" SFD10 before (the crevice tool, included with the Miele vacuum cleaner). The fit on the Miele vacuum cleaner is comparable to the SFD10.
The SFD20 consists of three parts: the connecting part of the vacuum cleaner, the flexible 36 cm long midsection and 6cm long hard crevice.
The 3 parts are assembled easily and without latching. The total length is 57cm.
The gap, in which you want to suck must be at least 20mm wide, because the nozzle at the front insertion region a measure of 35mm width and 17mm !! Having thickness.
And so I was annoyed at the time of the first application.
The front nozzle slipped and remained deep in the gap stuck ...
The flexibility is heat-dependent. After unpacking the package cold she was hard and inflexible, at room temperature, the nozzle could be a little more flexible, if you but does some time on the heater, it is quite practicable pliable, but the pieces slip apart more easily.
Conclusion:
++ Usable length of 57 cm
+ Processed optically good
o without Rating: Joint width min. 2 cm
- Could be more flexible
- Just put together, no lock
