Amazing performance for the price.

After using this foam cannon we are very impressed with the performance and it easily works as well as other brands costing up to 3 times the price. Highly recommend that you try it!

Great performance, but check for missing parts

This was my first time using a foam cannon, and it didn't work right out of the box. After a quick inspection, I realized the pickup tube was missing entirely. Even though the manual doesn't mention the tube at all, it's obviously a necessary part. Luckily, I found a tube around the house that fit. Once I loaded the bottle with degreaser and adjusted the knob, it produced a ton of foam. For the price, it's hard to beat the performance. I'm looking forward to putting it to work on the house siding next.

Foam Cannon

I only recently learned what a foam cannon is. I recently purchased a Westinghouse Pressure Washer that I am very happy about so thought this was a good addition to extend the usefulness of the pressure washer. I haven't used it yet. Im not expecting this to create a shaving cream foam texture but for the price I feel that I can't go wrong.
