Hi, Cnote 1080. This is actually a great question. On-board detergent tanks come with pros &amp; cons. Often, professionals prefer not to have them as they are another part of the machine that requires preparation for storage. The syphon function means less maintenance, but also a little less mobility. Since your pressure washer will automatically dilute your detergent, you can siphon directly from your detergent bottle, eliminating the need to measure or empty excess solution - simply put the cap back on when you&#39;re done. (link below.) We are confident you will enjoy the performance of your machine moving forward &amp; appreciate your feedback. <br /><br />https://www.samsclub.com/p/simpson-multi-purpose-1-gallon-disinfectant-cleaner/prod25831193?xid&#61;plp_product_6
