This does not work with most 2 gallon units and I believe it also doesn’t work with non-heated 3 gallon units. I have a 3 gallon, non-heated Sandia spot extractor and the spray hose coupler is too large. From other videos I’ve watched - it seems the heated units have a larger outlet on the unit.
We appreciate your review, Josh Grandt . We wish this Sandia 10-0503 4 inch Stainless Steel Upholstery Tool with 7' External Vacuum and Solution Hoses for 2 and 3 Gallon Spot Extractors would have worked out for you. Our Customer Solutions team will remain in contact with you about this.
