The combination of this 7" cleaning brush attachment and the low pressure water flow from the Hydroshot is an effective combination for removing stuck dirt and goods. Ideal for windscreens and grills, patio furniture, even the whole deck. Anywhere water pressure isnt right, this cleaning brush comes in and gives you a hand. You can even take it off and use it all by itself as a hand scrubber. It is installed either on the power nozzle of the Hydroshot or at the end of the long cleaning lance. And it locks into place quickly and securely. It is a perfect companion for spring cleaning outside your home or up in the cabin. Everything that needs a good and thorough wash will look like new when you are done with it. And its durable design means you will use it for many seasons.
