VAS which is really different

Dyson vacuum cleaners are made of plastic and it's true that they look a bit fragile.
I bought a Dyson and I was surprised at its efficiency, according to Dyson the efficiency remains the same after several years of use.
After 3 weeks, the telescopic arm was closing itself during use. I was in anger for a vacuum cleaner for this price. I telephoned Dyson (the number is written on the vacuum cleaner), and it sent me a new telescopic arm without asking me any justification, this sevice works for 5 years.
It turns out that the problem was not from the telescopic arm but a piece of paper stuck that created a vacuum, and the arm was closing because of this.
If the vacuum cleaner is guaranteed for 5 years, it is precisely because it does not fails often. Even though it will fall down, the SAV service is very fast and very effective.
