Watering Reel from Karcher without a hose. The capacity of the reel in meters varies depending on the diameter (thickness) of the hose. For example, the smaller the diameter of the hose, the greater the capacity. With the watering reel, space is saved and the hose is guided uniformly during use. Watering becomes particularly easy and convenient, while the hose is better preserved without kinks. The reel has a handle for easier and faster winding. Finally, movement is easier without having to lift the entire weight of the reel as it has wheels.
