The trend of the moment is definitely the wireless vacuum cleaner: in the wake of Dyson's massive advertising campaign, the convenience of having a sufficiently light and comfortable vacuum cleaner to carry in every room and even on several floors has almost become a necessity.
But if the purchase of a Dyson, perhaps the V8 model which is not the latest and most advanced, affects your family budget for at least 360 Euros and the entry price could represent a major obstacle, the range of competition and devices of Chinese manufacturers offer a lot of alternatives that can push you to buy a first-price product to evaluate whether it is really worthwhile to switch to a cordless vacuum cleaner or to use a classic tow-type product.
It must also be said that more and more users are using robot vacuum cleaners that may not be able to get anywhere or would be too slow to quickly perform a specific cleaning task and therefore the wireless vacuum cleaner becomes a useful ally to finish the cleaning or carry it out at the last minute. minute.
Among the many devices that are proposed to us for testing and that look a little alike we all chose this Alfawise FJ – 166A for a number of reasons: it is one of the most successful aesthetically with its white and aluminum livery, it promises respectable performance and has an easily replaceable HEPA filter (with spare part supplied). The retail price of about 100 euros, less than a few periodic offers, also seems to us an excellent opportunity to test a device that we have never used at home without having to ruin ourselves for the purchase.

The packaging
The cardboard box contains the vacuum cleaner with few frills: in practice we find the vacuum cleaner with its accessory brushes: that base for carpets and floors not so wide (and without the LEDs that make so much “future” (a standard nozzle along with soft extension (very convenient for cleaning the inside of car seats) and a short brush with double function equipped with retractable bristle block more suitable for cleaning crumbs or the car: it will be used without the long tube to have an excellent capacity The long tube with aluminum finish adds a touch of elegance to a device that does not appear so “cheap”.
Inside we also find a support to hang it on the wall (it does not stand alone like other “lighter” models) and the power supply, of very small dimensions directly with European plug on one side and coaxial connection on the other.
It must be said that compared to other cordless vacuum cleaners we are trying this one is very “detachable”: the battery block is completely detachable (and this offers extra safety), the tank that contains the dirt is easily removable and is There is a spare Hepa filter whose replacement is recommended after 6 months of use but you can wash it by hand once a month and extend its life as removal from the seat is quite simple.
On the back, just above the large “handle” that is used to use it thanks to the pressure of the internal red “trigger” we find the button that regulates the power (I and II) and 3 beautiful blue LEDs that show us the state of charge of the '' vacuum cleaner both during use and during recharging.
The tank is easily removable and thanks to a release on the upper part it can be removed to be able to transfer the collected waste directly above the bin.

The materials, however, are of first level

The configuration
The suction flow passes through the tank which is served by a series of filters:
Overall, the 2.8 kg of weight are well distributed even if, as we have already said, slightly unbalanced towards the handle. The noise level declared around 80 DB is lower than that of standard and low-power towed vacuum cleaners perfectly usable even in the very early hours of the morning without waking up the whole house or, worse still, the neighbors.
The charge, the power, the duration
The full charge of the vacuum cleaner, thanks to the 2,200 mAh and 22.2 V battery, lasts 5 hours after which we will have the suction power of 7.0 Kilo Pascal available: are there many? They are few? A trailed vacuum cleaner has a power ranging from 12 to 22 Kpa and therefore we must NOT expect the same suction capacity but we must understand if our device is able to clean an entire house in the useful time of its autonomy.
First of all, we must say that at standard power the vacuum cleaner works for about 40-50 minutes, enough to carefully “pass over” an 80-85 m2 apartment while at maximum power the use time is reduced to 20-25 with full charge. : the longest duration is obtained by NOT working continuously at maximum power and, since it is not necessary to keep your finger on the trigger to make it work, just remember to turn it off if you do not work continuously on the parts to be sucked.
We have reserved it for use at maximum power for cleaning carpets with dog hair (long hair) and cat and we must say that the result is remarkable even if the wide brush was not created specifically for this purpose. While access to all parts of the house is facilitated by the portality of the device, there is some problem getting under the sofas slightly raised from the ground with the floor brush because the motor is positioned “L” with respect to the tube and not it is possible to arrive almost parallel to the floor.
The motorized brush is not difficult to clean if the tufts of long hair get stuck: with a coin the small casing that protects the pulley is released and the roller can also be extracted for a thorough cleaning or period washing.
The same applies to the maintenance of the HEPA filter which can be washed and left to dry: in any case, the detailed instructions translated into our language assist us in everything.
Obviously, the operation to vacuum cobwebs, dust, crumbs is very obvious and by using the accessories directly without a hose the effectiveness on sofas, cars and tall furniture increases. As you have seen from the photos, the attachments are well protected electrically and mechanically solid even more than “noble” models.
Conclusions
It is a cordless vacuum cleaner with a good price-performance ratio: the polycarbonate finish and the aluminum tube give it a modern and elegant appearance and also the tank for the dirt collected, even if a little too darkened, contributes to making the Alfawise FJ-166A a product that seems to belong to a higher class.
In our suction tests on carpets and with animal hair it performed well despite the power not being that of a vacuum cleaner. The powerful battery guarantees a good autonomy in standard mode (you can easily clean an 80 sqm apartment with one charge) and if you want to manage a little more power it is at your disposal.
Pro Solid appliance, well built, easy to clean the floor brush, removable battery, good suction power, good duration at maximum power, very solid component attachments. Easy access to the tank and HEPA filter with replacement. Manual in Italian.
Cons Difficult to clean under low furniture with the floor brush, important weight of the suction terminal even if well balanced.
Price to the public Alfawise FJ-166A costs just over 100 Euros with 1.10 Euros for priority shipping in Italy. For more information on shipping costs and times, any charges and order management, you can consult the seller's website.
