Concrete Pool Deck Pressure Wahser

What is the best pressure washer to clean a large concrete pool deck.

I have been looking at some of the round rotary types. There are lots of options and prices.
The round rotary types need pressure well over 3500psi to clean well. Just rent the biggest one home depot has and it should be ok.
 
I bought this one on sale last year at Lowe’s, along with the 15” rotary attachment and I highly recommend it. 3000 psi was more than enough. I had years of dirt and sap drippings from lots of overhanging trees. And I have LOTS of exposed aggregate decking. The Greenworks cleaner worked flawlessly and easily. Decking looked like new. Also did the driveway and sidewalks. I went with electric because I didn’t want to deal with small engine gas/oil mixture or even storing gas and oil. The model I got stores vertically, allowing me to put it against the wall in our garage and still have room to park the car.
