High power pressure washer recommendation

Looking to replace my 20 year old pressure washer. It is a Troy-Bilt 3000psi 2.7 gpm with Brigg & Stratton engine. Looking to get something with a little more psi. 3600 or near there but not looking to break the bank. Primary use is on driveway and patio.

any recommendations please?

found this one at Lowes. Not 3600 but price is good. Maybe to good ?

Curious for your reasons to go +3000 psi?

 

Very long concrete driveway and decent to large concrete patio. I am lucky to have a lot of oak trees. I am unlucky that they really stain up the concrete. Especially when the pollen is falling. So want something that clears the stain quickly. I am also looking at purchasing or renting a surface cleaner and the recommendation I got was to connect to a 3600 psi.

 

We went looking for one about 7 years ago. Wanted a Honda engine, found it in a Ryobi at Lowe’s and it’s been a champ. Auto idle down, the frame folds up compact around the motor. Basic winterizing and oil changes. Might take it in for an official tune up after this year just for a refresh. But we use it a lot, it’s been awesome.

it’s not 3.6, but i believe it’s 3.2k
