False. The motor speed is fixed, but the efficiency of the pump is not. There is "slippage" past the pump seals and there seems to be a direct correlation due to the back pressure from the diameter of the nozzle orifice.

I've been able to manipulate the gpm with my active 2.0 by going with a larger orifice than stock, and then been able to retard my gpm with a smaller orifice leftover from my Sun Joe. It's as simple as a paint bucket with graduated measurements and the stopwatch app on my iPhone.

Also, watched it time and time again on YouTube channels such as IMJOSHV, Obsessed Garage, etc. For example, here is IMJOSHV's testing of the Active 2.0 that I purchased.

Fine, if you want to quibble about .075GPM and tell people you are dialing in your flow, go for it.

Less expensive models tend to get more gpm from the orifice diameter manipulation. I suspect the reason my Active 2.0 is rated for 200 hours vs most electric pressure washers being rated for 100 hours is the very reason the gpm didn't change as much as others.

I have a Dewalt and it does a great job and is powerful.

The one from Horror Freight is not bad. The pressure cable is pretty unwieldy, but I can live with it.

What I really want/need is an extended nozzle (Like 15 feet long) with a >90 downward angle that will allow me to hit the siding on a downward angle so I am not blasting the water and crud up the drainage holes on the bottom edges of the siding

Also, something to inject a cleaning/solvent into the pressure stream. The HF one has a tank, but it will only draw from the solution tank with the zero pressure tip that only shoots about 5 feet.

I have a Sunjoe 3000 that's been solid. Had it for close to a decade now.

I know people in the home snow making community seem to have good luck getting two of the cheap Ryobis and running them in parallel. If you are tied to electric but need more power you could do something like that.

^^^I woke up this morning with a headache and that is not helping.

Two electric pressure washers, plugged into different circuits, with the hoses connected after the pumps to a single hose, wand and nozzle.

Yep, head still hurts thinking about it.

I had a Kärcher electric and it served me well for a good number of years. Gave it to a family member after I no longer needed it.
