  • VERY NICE for the PRICE!
Color: BLACK-1 battery
The item arrived quickly and I used it for the first time without connecting it to a hose. It worked great!

  • On par with more expensive pressure guns
$9.99.....you can't beat that for a pressure washer gun. It feels good in the hand. Feels just as good at my buddies very expensive name brand one. Now it's probably not going to last as long as an $80 one like my buddy has but I'm also not an amateur car washing business man. I wash my vehicles every other week so I would expect this to last me a long time. Even if I have to replace this every year, it's still a better deal than buying a high priced one because that name brand gun isn't going to last 10 years. Like I said this feels like a quality pressure washer gun. This gun is so much better than the one that came with my gas pressure washer. Because it's smaller it's much more capable of getting down in the engine compartment, behind the tires and the undercarriage of my vehicles. Snug up the fittings and you shouldn't have any leaks. One thing to note on the pressure washer gun is on the body of the gun up near the top of the trigger there is some extra plastic that must have squeezed out of the mold and left a jagged scratchy piece of plastic. I took the blade of my knife and quickly cut it off and now it doesn't scratch my pointer finger. If you need a more portable pressure washer gun than the wand style gun that came with your machine, this is a no-brainer upgrade. Another tip that will make your pressure washing life easier is to pick up a pair of swivel connectors for the gun and the hose and then also pick up quick disconnects that way you can swap between the wand that has a foam cannon attachment and this handheld wand with Your 40° rinse nozzle. ... show more

  • Not bad for what it is and the price, but not a true power washer.
Color: BLACK-1 battery
Giving it a 3 star for now, mainly for the deceptive video. The power is okay. Don't expect to be able to do a great power wash clean on concrete or siding. DEFINITELY don't expect the power shown in the video (notice they don't actually show the washer in the video). May be pretty good for windows and the car. My biggest issue is getting the battery on and off. Needed a hammer to get it off and the hose didn't want to stay connected. In short, not bad for the price, but if you're wanting something to actually clean driveways, fences, siding etc... spend the extra money for the equipment and water for a true power washer. ... show more

  • Better than the huge wand that came with the pressure washer.
The pressure washer wand that came with my little greenworks 1900psi electric pressure washer is nearly 3 feet long. It wasn't fun to use when washing the car. I just wanted to get closer to the wheel wells and be able to spray the roof without breaking my wrists. Also, I prefer using a foam cannon with this where the weight is better balanced. This makes washing a car a much nicer experience. All the tips I have popped in and out without any issues and there wasn't any leaks from the handle areas. I didn't see any issues with pressure or power. I especially like that once I removed the hose and pulled the trigger, any trapped water just fell right out. ... show more

  • Water

Curiuos why there was water in the gun if this is brand new, or was it?

  • I do not think it is as good as advised.
Color: BLACK-1 battery
Just tested it a minute ago. I connect it to the hose with a convenient connector. as soon as I turn on the hose, the water comes out from the nozzle, which is unexpected. When I press the trigger, the water beam goes faster but also larger. The distance it water can reach does not increase. I did not have a way to test the pressure psi but I have a corded one (also about 900 psi) which I can feel the water force pushing back when pull the trigger but I did not have the same feeling. So my subjective feeling is that this is way lower than 900 psi. When I watch the video, I feel like it never shows the effects with the washer in the same video. That is dubious! In theory, I do not believe this wireless washer can be as powerful as traditional one. So I might not buy any more similar product. ... show more
