It's great pressure washing tool that attaches to the end of your spray wand and divides your stream of pressurized water into smaller streams, creating a wide cleaning swath. It will save you time & effort!
And you can see my #1 recommended water broom: the BE Pressure 85.400.061 Water Broom on Amazon!
It has a 1/4" quick connect plug, made of steel and is a generous 16" wide so you can do less passes.
For example, a typical driveway of 400 sq. ft. will take about 80 minutes to clean with a regular spray nozzle. But it can be cleaned in only 30 minutes using a water broom!
Widths vary from 12” wide with 3 nozzles, up to 36” wide with 7 nozzles. For homeowner cleaning projects, I recommend getting a 16” wide model with 4 nozzles! You’ll clean quickly while still maintaining an effective pressure stream from each nozzle.
