The Commander Cleaning Kit gives you two ways to use it: with the hose or with the bottle. Screw-on and screw-off connections let you attach or remove components as you change between those options. The kit is described as waterproof and phthalates free. Choose between the long nozzle, with 9 inches insertable, and the short nozzle, with 4.5 inches insertable. The different lengths give you a choice of insertion depth, while the hose option measures 59 inches long. Stainless steel hose: The 59-inch hose gives you an extended hose option. PVC parts: The nozzles and bottle are PVC. Aluminum connectors: The hose connectors are aluminum and screw on or off. Bottle dimensions: The bottle measures 5 inches long and 3 inches in diameter. Use the bottle or attach the hose, then select the nozzle length that suits your preference. The differing nozzle lengths and two use options let you choose how to use the kit.
