Noise: obviously, Marketing super-silence is not waiting for you, my son still asks me to turn off the unit when vacuuming in the same room ... But it is not going up 'to bother to turn off the vacuum cleaner, it was always with the old. There is therefore a better undeniable.
The parquet delta head (ZR901801) bought extra (parquet / tiled floors throughout) is top. Being super flat, it passes under the chairs without being asked, and the corners are a delight.
This vacuum cleaner consumes half as much as the former, if I believe the notices as he aspires REALLY better. The former was to have reached its limits.
On a "carpet" of small size, aspiration, supposedly ineffective on carpet for this unit (only noted D) is better than the replaced vacuum ...
In addition, exhaust air does not feel anything. It is super nice. Hopefully this will always happen in time.
The dust receptacle being transparent and consumable part, it is always empty. This is better compared to a bag (consumable) which we do not know more the filling state.
The unit is very compact, so it tends to reverse in tight corners ... A helping hand to make: no abruptness ...
The handle to the power control is a nice touch. Built to handle brush does not seem gadget.
The length of the cable and the hose allows me to connect "in the center" and reach the remotest corners ... Not bad.
A less: no accessory storage on the device, which are full (especially if the parquet delta head is added).
Why disappointed and only 4 stars? The "noise" is largely bearable but 68dB, it is however not the soft murmur touted in movies, advertising ... It's not an unpleasant level but still it keeps hearing the ringtone your mobile phone left at 3 meters.
The star is due less to the sirens of marketing, who place too high expectations, actually.
Why super nice ... The model replaced was 20 years old. it was heavy, aspired little exhaust air (do not talk) ... and noisy.
It remains to convince the fairer sex, attached to the former, an investment (yes, that, considering the price) every 20 years brings a definite plus in both performance (suction making the device actually fulfills its role, handling) in the ease of use (noise for vacuuming the living room door closed when the small sleeping in his bedroom, smaller footprint, no odor nuisance before the guests arrive .. .)
Most, in summary: little noisy (rather than silent), compact, bagless use on parquet / tiles smoothly.
Near zero default first impression.
But we must see this in relation to what I compare: a model 20 years of age.
Remains to be seen over time whether this device will keep the same level of performance, and it will fail in the next 20 years ;-)
