Abstract
A floor cleaner can include a housing adapted for movement over a surface to be cleaned and at least one edge cleaning brush provided on the housing. The edge cleaning brush includes multiple cleaning implements which rotate on different axes. A gear system, such as a planetary gear system, can drive one cleaning implement at a lower speed than another cleaning implement.
