Get hot water on demand for cleaning off house siding or outdoor furniture, and then turn down the heat to give your furry friend a warm bath or fill up the kiddie pool for your kids to play in! You can use HotWave anywhere you have a garden hose hookup and a power outlet, so it can be used at your home, on the farm, on your vehicle, at the campground, and more.

The Spray’s The Thing

HotWave’s multipurpose design features 3 spray patterns so you’re sure to have the right one for the job at hand. Change the pressure and spray pattern with a turn of the dial, and turn up the heat!

  • 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.

  • 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!
