Like others have said, it's the pump that you have to worry about failing rather than the motor. Cat is good for the reasons others have mentioned, namely being rebuildable. The Honda units are usually my recommendation. Thryre pricey. But as the saying goes: Buy cheap and you pay twice. Trust me, that's almost always the case with the Home Depot and Lowes branded stuff. Like Kobalt etc.
Also, take great caution in using them. Back when my dad wasn't retired and I was in High School,he bought a new Honda commercial washer. Don't remember the specs, but do know he paid around 4 grand. Needless to say this monster would easily scoure concrete! The point that I am making is that if your buying this to wash the car and do light cleaning, take care in not buying a unit too strong for the job and making sure you use the right nozzles.
Wish you luck.
