Grinds nasty weeds and algae out of block paving, no problem!
I have a few of the Einhell 5.0Ah batteries, plus a small 2.0Ah one, so thought I'd give this a try. The nylon brush wheel is perfectly capable of chewing off dandelion plants and small clumps of grass, but it was hard going on the solidified moss. Time to break out the steel wheel! This thing blasts through any plant matter in seconds. It took a couple of hours to do the entire 70m^2 driveway, but I wasn't destroyed at the end of it. Tool seems to have held up well, despite the hammering we gave it. Lasts a long time on the 5Ah batteries (went through about 1.5 of them for the whole driveway)
