The EB 30/1 Professional Li-ion is the first battery-powered electric brush on the market for professional use. In addition to a second replacement battery, the professional version includes a quick charger instead of a mains charger. This newly developed machine has an easy-to-replace roller brush and an easy-to-remove rubbish bin - a brush and dustpan in one. It allows fast, quiet (56 dB[A]) and reliable cleaning of hard floors and carpets during working hours.
