I used SCAMPER, Morphological analysis, and TILMAG on the "Magic Scrubber" faucet sprayer.
The original idea is a nozzle connected to the sink by a hose that sprays water when you push the trigger. When you push another button it dispenses soap. On the end of the nozzle is a scrub brush for cleaning gunk off dishes. It is a bristle brush that is easily cleaned under the faucet.
Substitute: Can I change its shape?
Themed sprayer, such as a ray gun:
Combine: Can I combine or merge it with other objects?
Merge it with a hair blow dryer to add a dish-drying feature:
Adapt: What could it copy, borrow or steal?
Take the handle grips and adjustable flow features of a hose spray nozzle:
Modify: What can be extended?

Put to other use: What else could it be used for?
You could fill it with laundry pre-treatment fluid and use it to pre-treat stains on clothes or to hand-wash clothes:
Eliminate: Should I split it into different parts?
Make the brushes removable for easy cleaning and replacement when they wear out:
Rearrange: Are there other patterns, layouts, or sequences I can use?
Change the handle and button layout to be more comfortable for various hand sizes, for example:
