How do I fill the clean solution reservoir on the Dirt Devil Spot Scrubber?

Fill the cleaning solution reservoir with approximately 112 oz of Dirt Devil Carpet & Rug Shampoo, then fill the remaining space with hot tap water. Replace the cap securely after filling. Only use Dirt Devil Carpet & Rug Shampoo, as other cleaners may cause excessive foaming and void the warranty. (Page 2)
