A suction nozzle for a vacuum cleaner has a housing, a vacuum mouth disposed on the floor side in the housing, a cleaning roller mounted to rotate in the housing and driven by an electric motor, and a rechargeable battery unit for the energy supply of the electric motor. Via a rear connecting piece, the suction nozzle can be connected to a suction tube or a suction hose of a vacuum cleaner. The electric motor has a rated power of between 50 and watts, and the rechargeable battery unit has an energy density, relative to its total volume, of more than 200 watt-hours per liter (Wh/L).
