Do you wanna spend $30 dollars to keep that from happening? No? Good, I'll show you how to do it for $8!!!!!!
Step 1: What Do You Need???
A 1 1/2" vacuum attachment ($8)
Your pet brush (I assume you already have so I didn't include it in the cost)
Step 2: Preparing the Attachment
This may vary depending on want kind of brush you have. I'm using a furninator.
Mark the length you need and cut it to size.
Sand the sharp edge after you've cut it.
Step 3: Making It Fit
I did this by heating the round part with a lighter and formed it with a piece of scrap PVC pipe.
Be careful not to burn yourself.
Cut the any access plastic off of the attachment.
Step 4: Zip Tie It!!!!
Step 5: And.......your Done!!!
