I have been doing some research on pressure washers and feel like I am falling a bit short on locating exactly what I want. The main thing that stuck out to me when researching is that on the units that are ~$250 to ~$350 is the pumps are sealed and "maintenance free". My view on this is similar to that of "maintenance free" automatic transmissions. As in there is no such a thing and that fluid/lubricant eventually has to be replaced if you want a long life out of the unit. I feel like spending money on "maintenance free" is equivalent to spending money on a ticking time bomb. It's not a matter of if it will go out, it's just a matter of when. In looking at pressure washers that have the drain plug on the pump for the purpose of maintenance (what I've found so far), they are ~$900 and up. So, clearly I am missing something between $350 and $900. I have to be. Are there pressure washers out there between $350 and let's say $500 that have pumps that allow maintenance? As for PSI, I would like at least 3000 PSI. I'd rather spend once and be able to do maintenance for years of service. A pressure washer with a horizontal mount pump is what I would strongly prefer for the ease of maintenance. All suggestions are welcome.
