Westinghouse Pressure Washer Foam Cannon

The foaming cannon is great! It integrates well with the 3400 Pressure Washer Electric. I'd recommend it.

Wow works as described.   Easy to use .  Better than a commercial car wash.  Adjustable foam quantity.

Have only used once, but so far it does a great job.

Easy to use

What a wonderful attachment.  This is great to have for our big concrete areas.

Works exactly as expected

Works so much better than I expected! Used it with a 2700 PSI Pressure Washer on sidewalk.

Cleaned the undercarriage of my vehicle to thoroughly remove road salt and debris.

Works great

Bought this to go with my Westinghouse pressure washer (which is great) in Sept 2024. I used it on my driveway with fantastic results. Fast forward to September 2025, and I went to do the same driveway, but it just won't spin. The filter and nozzles are clean. It appears to bind against the washers. I took it apart, cleaned everything, and it worked for a few minutes, then again stopped spinning. I looks like the nylon that it spins on has just worn down. This is apparenty not a replaceable part so it's just one use and done, don't waste your money.

Didn't last

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.
