Greenworks GPW2005 Review
Pros: Very quiet, retractable handle
Cons: Pricey, so-so to roll around, mediocre cleaning power
Our Analysis and Test Results
The GPW2005 scored just a little too low and costs a little too much to be a good recommendation for a budget buy. It's close — but not quite.
Out of all of our tests, it was only in our noise test where the GPW2005 significantly stood out from the rest of the group. It is one of the quietest models while running, with our sound meter only showing 73.6 dBA when it was right next to this pressure washer and 62.9 dBA when it was 25' away.
We also really liked the Greenworks GPW2005 hose storage system. It has a spool system that keeps the coiled hose neatly out of the way but it can be a bit of a hassle when you are rolling or unrolling it, especially if you try and use the crank arm — we generally just turned the wheel by hand.
The handle on this model retracts but the fully assembled wand is still quite tall. However, you can unscrew the want into two pieces to minimize the space this machine occupies, though this is a bit more of a hassle than we would have liked if you are planning on using this pressure washer again shortly.
We generally reserved this for when we were storing the GPW2005 for longer periods. The Greenworks isn't overly heavy, tipping the scales at just under 30 lbs, and rolls around fairly well on hard surfaces.
We also liked that the nozzles store conveniently on the handle, compared to on the main base like other products.
Finally, the Greenworks GPW2005 is an electric pressure washer, meaning it requires significantly less preventative maintenance than a gas-powered machine to keep it running in tip-top shape.
Regrettably, we weren't very impressed with the cleaning performance of this pressure washer, which is pretty much the main reason you would even buy one. This machine delivered a mediocre performance in our carpet cleaning test, taking 5-7 minutes to remove the activated carbon from the rug — something the top machines only needed 2-3 minutes to do
The GPW2005 only managed to lift the bocce ball a maximum of 2.3' up the inclined slope of our testing trough — much less than the 6' or 7' the most powerful models could achieve. We measured a flow rate of 1.2 gallons per minute and a pressure of 1400 PSI with a 25° nozzle, leading to a slightly below average 1400 cleaning units (CU).
While the unit does easily roll over hard surfaces, it is hard to traverse dirt, grass, or other uneven terrain — even with its larger wheels. It bounces around unpredictably when pulling it and the handle can accidentally collapse if you try and push it.
Finally, we found the wrap for the power cord to be far too small for the approximately 35' of cable this pressure washer has, which usually ended up in a tangled mess if you don't get very creative to store it.
Overall, we don't think the GPW2005 is a great bargain buy. It costs a little more than similarly spec'd machines and performs a little bit worse, making it a hard sell if you are looking for the best bang for the buck.
We found the Greenworks GPW2005 to be mediocre at best and it wasn't a strong contender for any of our awards. It does have a few cool features and cleans alright but we are fairly certain that other models cost less and would serve you better.
