Hi msbikerone! Let us share a few tips with you to help get your Easy Steamer working like never before! When attaching or installing the accessory hose onto the cleaner, align the tab of accessory to opening on the body of the steamer. Then, rotate until the accessory is aligned with the locked position on the hand steam unit. To install the steam diffuser, angle adapter, or grout brush, be sure to firmly attach each component onto the concentrator nozzle or hose. After doing this, you should be good to go. Remember, you can always find replacement parts/accessories here: http://bit.ly/1MTchLB, under the parts tab. Let us know if you need any more assistance. Thanks!
