yea it's called a surface cleanerI don’t remember what it’s called but there’s a rotary head attachment for like $60 but it leaves a perfect finish and covers a huge area.

i have one too, it's basically a rod with 2 nozzles on the bottom, it "floats" on brushes all around the circumference so thats how it's "easier" to clean, you just go swish swish a few times instead of have a a clear back and forth motion
HOWEVER, you can't adust the nozzles or the pressure, if you just use the wand, you can go close or further away to increase/decrease pressure, this doesn't really matter with the surface cleaner since most ppl use it for driveways/concrete, and i'm sure it'll be fine for wood.
but for that deck where the wood is older than most ppl on the forum... maybe not
