The device works with the Ryobi 18V battery usual and has a bit more power than other devices with only 4-8 volts. One may wonder but also here not expect. After all, the cuttings, the sawdust, the breadcrumb & co. go from the mostly quite smooth surfaces in the garage and in the factory basement from largely without problems. The nozzle with a brush is good to get as well as in small crevices. Workpieces I clean anyway always with a cloth. The effect in carpets, upholstery & co I can not really judge, here I use still 220V sucker. The unit is well made and can be empty and clean very easily.
Curb the coarse dirt ado for the purpose (for example, when drilling with the battery percussion drill) I would buy the device again. Only a little more accessories (including the sometimes even called bracket) is desirable.
