Belt-drive pressure washer outlast direct-drive

Simpson power shot 4200 This commercial belt-drive 4200-psi water blaster pressure washer uses the industry’s best gas-powered OHV 4-cycle engine. The 13hp Honda GX390 is quiet, easy to start with the reliable pull rope. Protected by an oil alert system that both, shuts the engine down when the engine oil level is too low. The oil alert system keeps the engine from starting when it is low on engine oil. Fuel efficient, quiet running, easy to start and outlast lesser gas engines, you have to like that.

Using the dual V-belt cast pulley system, the power from the GX390 drives a commercial belt-drive triplex plunger pump. This set-up in my experience renting these type machines will outlast 3+ to one lesser direct-drive systems used on what turns out to be disposable power washers.

I really need a good power washer, I bought a cheaper brand at the DIY and well it was junk. I have a new brick driveway, its so beautiful but a few oil spots made their way on my beautiful brick driveway and the junky power washer I bought did not work. I figure I'll need a good one to maintain my brick pavers. Thanks Mike, as always your my go to guy for DIY tips that work.
