Though the DCPW550B 20V Max is a little bulky with the big battery compartment and the pressure isn't the strongest (but on par with similar tools), it is a great solution for small on-the-go and remote cleaning jobs. Lead times are shown on the product and trolley pages and are always advertised in working days (Monday to Friday). I also kept having it lose pressure, maybe like an internal tank was being drained as I would go along, so I would have to stop spraying for a minute and let it catch up.

To be honest, there aren’t really that many great models out there to pick from, but the four we reviewed here are in our opinion by far the best out there at the moment. It removed the green algae stains from an old car, but you have to get the nozzle close…like three inches away and work patiently in narrow strips of clean.

The DeWalt DCMPW1600N 18V / 36V XR Brushless Pressure Washer has 3 Pressure modes that provide optimal cleaning power and enables longer run times for less intense tasks such as car cleaning or even patio cleaning.

Bought one of these for cleaning off the gear on site as its portable, runs on battery and can take water from a bucket if needed.I don’t foresee this pressure washer doing that, but at the same time, do you want that kind of pressure when you’re washing your car?

One thing I don’t understand, is why Greenworks didn’t put wheels on the water tank, as a full tank can be quite heavy. Cordless pressure washers are the least powerful of the main 3 types and are not really the thing to be taking to industrial sized cleaning jobs or even trying to shift very stubborn stains, grease, and grime. It’s not a huge problem because, as mentioned, the tank has wheels to get around on, but I still found it a little annoying. Pressing the tube connector on is very stiff, but it must be fully in, or air leaks will prevent priming.Some of the seams where the two halves of the body meet are slightly sharp, but in areas you’ll probably never touch anyway.
