After 18 months of use, this product, yet described as "professional", were disappointing. For if the stainless steel tank is actually very solid, as no doubt (or maybe) the engine, the entourage will not. The handle, for example, is very thin plastic. And of course, it breaks! Or a device of this type is intended to be much worn and should have an aluminum handle, which naurait cost only a few euros more to manufacture. And impossible to find a handful of spare parts. Must redeem all engine! In addition, without a handle, the filter is raised and constantly flies! The front guide wheels: a flinched, then the other: you have to lug the camera! In short: imagine a car very strong engine, but with the dézinguerait dashboard, seats sag, the doors would fall by themselves! You would be satisfied? So Conclusion: Very disappointed! For that price, I could have 2 vacuum cleaners "unprofessional" that would work probably much better today!
