Amazon Basics Foam Cannon with 1/4-Inch Quick Connector for Pressure Washer, 33-Ounce (1 Liter)

I bought this to fit to my Bosch AQT 120 pressure waster. I needed a different adaptor to use this foam gun. I bought the adaptor from eBay for 4.25 GBP from Hong Kong. I could not find adaptors for AQT pressure washer in Amazon or they were expensive. The one I bought is made for Black & Decker pressure washer, but is the same for AQT pressure washer. Other Bosch pressure washers have a different adaptor. Tested with the new adaptor and works perfectly. Except for the adaptor issue, this foam gun is fantastic.

Produces good thick film of foam. Seems well made and cheaper than branded alternatives.

For a cheap cannon, this is rather good, it does not foam up and stick as much as you would like however for less than £20 you really can’t complain, it’s got a great build quality and has brass fittings so you don’t tread the bottle, I would highly recommend this product; the only thing I would suggest is the inside the cannon you change the internal nozzle to a smaller one

Excellent works better than the expensive ones

After using a proklean lance for over a year and having it fail I purchased this, it came with a quick connect adapter which matched my pressure washer, it creates good thick foam with minimal product use, the threads on the bottle are much better than the standard plastic into brass. the fitting on this is 2 brass connectors, one is permanantly attached to the bottle and makes filling easier. Works just like the more expensive lances.

Good. Took 2 star away because the socket that connect to the pressure washer gun requires Teflon tape for a leak free fitting. I found that when I was at a gig and got water all over me. Other than that, seems to work fine.

Great product and deliver fast.

great overall product, large bottle and good hardware. Could do with a rubber seal between the bottle and nozzle as it does leak a little UPDATE: the screw between the lance and the bottle have merged in place and no longer unscrews, binned after 2 1/2 months

This is an excellent product for the price! The build quality is solid, and it feels very durable. It creates a nice, thick foam, making cleaning effortless. I use it with my Greenworks 1800 PSI pressure washer, and it works perfectly. Great value for the money—highly recommend!

RAS !!! Pas encore utilisé mais le produit est bien fini et semble costaud. Cordialement

La foam gun lavora davvero bene! Se trovate le giuste diluizioni per i giusti prodotti, non vi deluderà! L'attacco è anche compatibile con i glaconi graduati MaFra, così da avere qualche bottiglia in più. Occhio alla manopola di regolazione: il + sta ad indicare che la soluzione verrà diluita con più acqua, anziché essere concentrata buttando più prodotti. Per calcolare le diluizioni corrette dunque, il mio consiglio è di tenere la manopola tutta al minimo!

good for the price and thick foam.

Grabbed the Amazon Basics 1L foam cannon on October 24, 2025. Running it on my 3000 PSI gas pressure washer and it absolutely blankets my 43ft fifth-wheel RV and F-250 Super Duty in thick, snow foam. One slow pass and the whole side is buried. Setup: 60 seconds. Fill with quality soap (undiluted or barely diluted), screw bottle on, click the 1/4" connector, , and unleash. Adjustment knob gives perfect control over foam density and pattern. Watery foam? Wrong soap or too much dilution — this cannon isn’t the problem. Used it 7+ times on big, dirty vehicles — zero leaks, cracks, or issues. For the price, performance is ridiculous. Some reviews mention early breakage, but mine is rock-solid so far. Best bang-for-buck foam cannon I’ve ever used on a gas washer. 5 stars all day.
