Amazon thank you for the price of this product (100 euros cheaper than the store!)
So it is noisy but at least we know why it makes noise. Teddy bears are drawn 2 or 3 centimeters of the brush. The crumbs come in one single pass, finally!
Cereals also come but we must raise the brush to "drop" on it, so if a chocapic is down, the best is yet to take the hand that is faster (I say this for the comment that speaks of inability of this vacuum cleaner to suck grain ... if there are plenty on the ground simply remove the brush and let the single tube!)
The 13 minutes of battery life are sufficient to take care of everything down to the house and teddy top (100 m²)
It can replace a real vacuum in an apartment of 60-70 m² if used regularly.
Only complaint previously reported from other reviews: we must keep the finger on the trigger, after 10 minutes it is true that it becomes painful but I wonder if it is not voluntary to avoid overheating the motor.
Each release (displaced chairs for example), it stops sucking and battery saves a bit and the motor.
The wall base we very suitable (2 screws to put though), it goes everywhere (starts perfectly horizontal).
After 15 days of use we are very satisfied, the material "breathes" the quality and the crumbs have finally disappeared from the kitchen (often had to get out the big sledges as yet without our highly rated thread was unable to deal !)
We will return in a few months to report a possible concern but for now, it's impeccable. This is our first Dyson, we thought it was a bit overdone but the price gap with conventional model seems largely justified (at least on Amazon).
