Improved product design

This is a.perfect addition to any pressure washer. It's a fan spray that quickly removes soap and material that has been previously loosened up faster than any of other attachments that I've tried.

My new favorite tool!

[This review was collected as part of a promotion.] This plugs right in to my pressure washer. So easy and quick. It delivers the perfect wide jet-stream to strip away stains and debris. It's very well made, while remaining light weight. I am really impressed with the results and have used it to clean around my pool, my pool chairs, driveway and deck. This is my favorite new tool and I couldn't recommend it enough.

Save water while cleaning effectively

[This review was collected as part of a promotion.] This was a simple to use attachment for my electric pressure washer. The quick connect system popped on immediately, and i was able to direct a wider pressurized spray of water where I wanted it, saving water while still getting an effective clean. Great for driveways and cars. Highly recommended!

dissappointed

This is a replacement for a 20 year old gas powered Karcher pressure washer Quite honestly I'm disappointed in the cleaning ability is compared to its previous gas counterpart while it's lighter and easier to use it can't tackle nearly the jobs that my old gas powered washer with higher gallons per minute
