[This review was collected as part of a promotion.] This is great for spot cleaning smaller stains, or big stains on smaller areas. I attached this to my pressure washer to clean some stains on my driveway, it took just a few minutes. It easily attaches.

Bring back the old version of Pump Guard, The threading on the attachment tube did not match properly with the power washer attachment and only engaged a few (if any) threads and when I tried dispensing to my power washer the contents sprayed on out on the ground.

[This review was collected as part of a promotion.] I tried the Kärcher Pump Guard Aerosol 4oz can and I have to admit it was a whole lot easier than I thought it would be! I didn't think I would really need it as I live in a fairly warm climate, but we do have a lot of mineral buildup and in the winter we definitely get some cold temperatures at night so I figured I may as well do the recommended care and maintenance of my pressure washer! The formula is designed to help lubricate and protect the pressure washer from rust and corrosion. It's a bit ironic as I was delayed in trying this because some of the mineral deposits had started to harden around the inlet, making it very difficult for me to remove the hoses. I finally got those off and now I have a greater appreciation for how this works! The sprayed itself was incredibly easy to attach to the inlet, and the container was light with an easy to push distribution button. Huge bonus with something like this, it's a biodegradable formula. If you live in a cold climate, it also works as an antifreeze protection. It is personal and that it is able to be used with both gas and electric pressure washers. I really thought this would be a lot harder than it was. It was actually incredibly easy!

[This review was collected as part of a promotion.] I'm so happy I got to try this Karcher pressure washer attachment. I was working on a project in my backyard and needed to spruce up our wooden fence. I was able to clean it quickly and easily due to the wide spray. The exact attachment that I needed to add to my accessories!

[This review was collected as part of a promotion.] The booster in power is noticeable right away. The spray is stronger and more focused than the standard nozzle. So tough dirt comes off faster and big areas take less time to clean. It snaps onto any electric pressure washer with 1/4” quick connect and up to 3000 psi. The setup is effortless.

[This review was collected as part of a promotion.] I absolutely love this brand! Excellent to use this on my power washer. Powerful and functional. Great value and removes dirt easily. Way to maintain and wonderful to remove debris. Highly recommended. Great tool!!

[This review was collected as part of a promotion.] The cleaning is excellent and quick, and the quality is superb. The size is great, as is the design. And maintenance is easy. Everything is very good; I can recommend them for cleaning any area.

[This review was collected as part of a promotion.] It's very practical and very good. It connects easily and its material is durable. It is necessary to wash cars as well as water floors or grass. It works perfectly

[This review was collected as part of a promotion.] My husband says it works perfectly. You can attach it to any pressure washer up to 3000 PSI max pressure and 1/4” quick connect connection saving energy and time.

[This review was collected as part of a promotion.] Easy to use! Just screw it on and press the button. We'll have to see later how it works (it's currently winter). But, looking at other reviews it should keep the washer running for a while!
