Best budget pressure washer

[Mikep]

Hi all just looking for some advice. I been a self employed handyman for 10yrs. Don't do much pressure washing but a couple of customers have been asking. I have a nilfisk I use at home but the patio cleaner accessories are enfuriating must of had 3 now use them a couple of times and there done, tried taking apart and cleaning does nothing. So my question is what is the best budget electric <500 that has a decent patio cleaner attachment that doesn't fail after a couple of spins. Thanks in advance.
