Using this pet vacuum brush is easy. First, attach it to your compatible Dyson cordless stick vacuum. Then, gently run the brush through your pet's fur. You'll notice that it effectively collects loose hair and fluff. When the bristles get filled with hair, just push the bar to clear it. As for maintenance, make sure to keep the brush clean after each use. You can simply remove the collected hair and debris. Store it in a dry place to avoid rusting of the stainless - steel bristles. Also, be gentle when using it on your pet to ensure their comfort.
