The handy device can be operated with all Bosch 18 V 1.5 - 6.0 Ah Home and Garden batteries and, with a speed of 1,800 RPM, is the ideal helper for clearing joints of weeds and moss. The brass-coated steel wire brush impresses with a working duration of up to three hours on concrete stone. Additionally, Gloria offers a nylon joint brush as a gentler option for scratch-sensitive surfaces. Precise and safe operation is guaranteed thanks to the guide wheel and sight line. The surrounding splash guard ensures cleanliness, and the adjustable second handle promotes a healthy posture while working with the joint brush.
