Review on EWK Pressurized Injection Canister Cleaning by Jay Kowal

Plug into working vacuum, add cleaning fluid to canister, auto start, turn on drip irrigation, wait for cleaner to penetrate. Stop the engine, disconnect and reconnect the vacuum source. User friendliness. I wish it had a sight glass to make sure the cleaning fluid is moving and the cleaning fluid reservoir is empty. In my experience, each ounce of cleaner takes about a minute. No, I have nothing to do with the company or Revain.
