Super vacuum, the rest still less

Hi, I bought this mower for nearly a month and I'm not totally satisfied.
Here objectively my impressions in use.
I'll start with what is really good:
- The vacuum is really a good idea, it is 90% effective, more sink clean with plenty of water or hair on clothing.
- For the battery, the charge is quite fast (about an hour) and the duration of use is really good (I have still not recharged since the first charge, with a blow of lawnmower twice a week).

What's good:
- The mower is beautiful
- Easy adjustment of the cutting height
- Reserve hair empties and cleans up easily (with another brush that comes with the mower)
- Mowing is soft, it's not very noisy (suction is the loudest).
- Cutting height is accurate, however, requires perspective because it must pass several times over the area to avoid having different heights ...

What is disappointing:
- Clean the mower as well as my old mower to 25 (purchased in 2003) .... given the price of the new mower is frankly disappointing.
Indeed, we must board several times over the area and if the marks were able to conquer the neck this is absolutely not the case with this mower ...
- The on / off button is badly located, too low, it is not practical or ergonomic, one wonders if those who designed this mower know what it is for ... and if the location of their inch is the same as our !!!
- The small brush to clean the mower is HON-TEU-SE-MENT small (worthy of a doll house) ... keep your treasured old, it really is not a luxury.
- There is no head (or optional) to shave nose hair, again keep your old mower (if it is not cramée and if you had a good head not look like Cro-Magnon man with a tuft at random ...). But you do not have a choice, you will be "responsible" for your weekends and holidays ...

In short given the purchase price:
The Most:
- Aspiration hair
- Easy cleaning of the bristle container (provided you have his old brush)
- "Short" duration of load and resistance over time for use when loaded
- Easy adjustment of the cutting height
- The product aesthetics

The Cons:
- The efficiency of mowing (often on board areas, especially the neck ...)
- No head (or optional) to shave nose hair

The Very Cons:
- The ergonomics of the on / off button
- The size of the cleaning brush

Up to you, really nice for innovation of aspiration, but the rest is really disappointing for a lawnmower at this price, you can find better or worse as well and with more equipment for another half mower price ...
