Abstract
In a brush assembly of a cleaner including plural brushes arranged at the bottom surface of a cleaner body radially at regular intervals; plural supporting shafts for rotatively supporting the brushes; and a driving unit connected to the brushes in order to rotate the brushes, by arranging the plural brushes radially, dust and filth can be collected in a wider region, and accordingly a cleaning performance can be improved. In addition, by forming the brushes as a curved shape, it is possible to compact a size of the cleaner.
