No worse, no better than the other

1st test:
although it sucks but I quickly lose power, the engine heats up, the plastic in contact too, it shows.
I could not finish cleaning my chimney, the filter is already completely clogged.
Long and difficult cleaning of the filter that will never regain its original porosity.

2nd trial charlotte on the filter:
same as before but it sucks a little longer this time.
Disassembly, I realize that the charlotte comes off the filter and how all this is located next to the arrival of the ashes, I am even more dirty filter since the charlotte has accumulated ash.
However no engine overspeed this time and no burnt plastic smell.
Another tedious filter cleaning in anticipation ...

3rd trial charlotte and elastic:
This time, charlotte securely attached to the filter by a rubber band.
Always the same aspiration and no engine heater.
Disassembly is disappointment, charlotte has retained a small portion of ashes.
I'm going to spend more time to dust, wash, dry the filter to clean my chimney.

CONCLUSION:
The pros:
- Not worse than others
- Low investment
- Suction hose and cable length of good food
- Avoids putting ash into his stay

The -:
- Not better than the other
- Really noisy
- Is not performing as it stands
- You spend more time cleaning the filter to clean his chimney
