Bought a Degritter this year after using a VPI 16.5 for almost 10 years. I used 3 steps (enzyme, cleaner, ultra distilled water rinse each step with its own brush and vacuum wand) with the VPI and had very good results, but the time for each album was almost 30 minutes... the Degritter, using their surfactant additive, requires at the most 10 minutes (usually about 5 minutes) and I am not participating in 95% of that time. The results are better than my previous three step process. Highly recommended.
