This impressively versatile EB 30/1 12" Cordless/Electric Sweeper (1.545-121.0) from Karcher is great for cleaning all sorts of spaces. Equipped with a convenient foot-operated on/off switch, it's only 90 mm tall so it's flat enough to reach beneath radiators and furniture with low ground clearance. It picks up loose dirt within just 2 mm of its edges while the universal joint enables it to move in all directions. Plus, no tools are required to change the batteries or remove the roller brush.
