With the Gardena Spray Lance, with the length of 60 cm, for long-reach washing, with spray jet, the boat can be gently and precisely spray.  The water flow can be switched off.  Soft plastic ring on the head to protect from damage.  Thanks to its length it is particularly practical for larger areas.  If the water flow is to be continuous, you can lock the pulse trigger.  Tiring of the hand is thereby prevented.  The hanger attachment allows quick and easy storage after use.
