4 Spray Patterns

So You’re Sure to Have the Right One For The Job at Hand

  • Shower
    This setting provides you with the highest flow and the maximum amount of water. Cleaning your pet, hosing down a kid after a trip to the beach, or just washing off dirty shoes from a muddy hike is faster and more efficient with warm water and the shower setting, so spray away!

  • Flat
    Watch soapy suds wash away from the car or even your dog. This spray pattern is useful for a variety of jobs, but gentle enough for your furry friend.

  • Jet
    The strongest setting for tough jobs. Wash away grease and dirt using the jet spray pattern on house siding, an outdoor grill, a dirty horse stable, and anywhere else where you need the maximum spraying power.
