Cheap Foam Cannon/Pressure Washer Setup

Can anyone recommend a super cheap electric pressure washer/foam cannon set up? Looking for something I can plug a hose into and get to work. Trying to shorten the wash process.

I remember some members here recommending an electric pressure washer from Amazon.

If I'm not mistaken, all I need is the pressure washer (which comes with the wand I assume) and an attachment that holds the soap on the wand?

This has been talked about a couple times. This thread may help.

Check out the snow foam lance on aliexpress.com. Multiple connectors available depending on the brand of the pressure washer you are using. Very robust build quality... Priced very competitively.
