Using this pet vacuum brush is super easy. First, attach it to your Dyson V7, V8, V10, or V11 cordless stick vacuum. Then, gently run the brush over your pet's fur. Your pet will feel comfortable, and you'll be able to collect a lot of loose hair. When the bristles get full of fluff and hair, just press the push button to clean them. As for maintenance, after each use, make sure to clean the brush thoroughly. Store it in a dry place to prevent rusting. And always double - check that it's properly attached to the vacuum before using it to ensure the best cleaning performance.
