Loving the results!!

[This review was collected as part of a promotion.] After a long awaited time period, finally got to using the attachment to power wash my car. The results definitely did not disappoint. The pressure is perfect. It dispenses just enough to get the job done thoroughly. I forgot to take a picture of the before but here is the after. I love the shine and the reflection!

Very well made. Seems better than many others

Would Recommend

[Employee of lowes] If you own a Simpson pressure washer you will need an adapter to attach this foam canon to your wand. The part you need is SurfaceMaxx Item #2637680 M22 (14-mm) female to 1/4-in Brass Gas and Electric Pressure Washers Quick Connect Set. You need to remove the lance from the wand in order to attach the adapter.

It doesn’t fit my Westinghouse pressure washer

Would Not Recommend

Maybe it was a machine error on the part, but it was too long for the quick disconnect to close.
