The advantage of the tested battery stick vacuum cleaner is the high suction power and the electric drive of the rotary brush in the floor vacuuming attachment, which significantly contributes to the efficiency of vacuuming carpets and smooth floors. Silvercrest Shaz 22.2 F7 has a motor with a maximum power of 130 W. Despite the powerful motor, the vacuum cleaner is very light and compact

The package includes a wealth of accessories, including a small charger and a practical accessory holder with a carrying handle. The removable battery has a capacity of 2500 mAh at a voltage of 22.5 V. A simple calculation reveals that it is 56.3 Wh. The manufacturer’s claim of 25 minutes of endurance in boost mode at full power is very serious, and my testing confirmed it as well. In ECO mode with lower power, this vacuum cleaner can last 45 minutes on a single charge. In practice, this is more than enough to vacuum a medium-sized apartment. Carpets with a longer pile, which puts more resistance on the rotary brush, will reduce the duration to approximately 35 minutes. The power status is indicated by four oblong LEDs. ECO mode was enough for most surfaces. I switched to Boost mode mainly when vacuuming cobwebs, or from the folds of couches and seats. The LED indicator is not linear, which corresponds to its shape, where the LED showing the maximum charge is the widest. The charging source with a proprietary connector is connected to the cut-out from below. Such a construction solution allows you to charge the vacuum cleaner also on the included holder, which you can fix on the wall or wall near the outlet and the vacuum cleaner is charged in the holder
For vacuuming, you can use a combined floor brush, crevice nozzle and a nozzle with a round removable brush. The package also includes a practical holder for this accessory, which can be attached to the aluminum suction pipe.
If you do not install the oven, you have a practical hand vacuum cleaner, for example for vacuuming a car. The oven has contacts for supplying electric current to the motor driving the rotary brush in the floor attachment. The system of connecting the oven with the vacuum cleaner and attachments is well designed without any play.
Thanks to the joints, the combined attachment with the rotary brush enables excellent maneuvering even in confined spaces or under furniture. The wheels facilitate the movement of the attachment on the floor. Since there is electricity in the floor extension, it’s a shame that the designers thought to build in an LED light to illuminate dark corners
During testing, I vacuumed several times the apartment in which three dogs live with us, one of them has long fur and crawls quite intensively. The vacuum cleaner handled it just fine. Even most of the longer hairs ended up in the reservoir, only occasionally one or two remained wound on the brush barrel where they could be easily removed. I vacuumed the spilled rice on the long-pile carpet in one pass with a brush, I needed two passes for the spilled salt. Then I combed the shaggy dog and “worked” the hairs obtained in this way into the carpet. After the first pass, most of the hairs were vacuumed, and after the second pass, all of them. Cyclone filtration is very effective and captures even the finest dust. Even after vacuuming very fine dust, the EPA filter remained clean.
Dumping the dust is easy, just open the bottom of the collection container. If there is dust with fibers in the upper part of the cyclone, you can remove it by turning the container and you can remove the filter. It consists of a cone made of thin perforated stainless steel and an EPA filter. Both filters can be rinsed under running water. They must be allowed to dry before placing them in the collection guide.
Verdict: A practical cordless vacuum cleaner with sufficient suction power and electric rotary brush drive
