This device, very easy to fit in her luggage through the sliding tank, is very powerful and I use 1st gear; if the tip seems large compared to other brands, it cleans very well. Moreover, the rechargeable battery takes longer for use 3 times / day: I get 15 days holiday and it is still not discharged? The tank is + than enough for I filled it at 1/3. However, one must be careful to empty the tank after each use because the water quickly rotting in this material.
