I had a pet tool attachment left over from my previous Hoover vacuum that I wanted to still use with my Dyson, somehow. I don't know how many other people have this same predicament, but here it is if anyone else wants to do the same.
The Hoover 000977002 Vacuum Cleaner Pet Turbo Tool Attachment needed some maintenance before I could certify this in good working order, since the internal moving parts needed to be cleaned and I noticed it becoming ineffective with the vacuum this came with.
It turns out that the Hoover vacuum motor just gradually started dying, because this pretty much worked perfectly fine with the Dyson before any of the aforementioned maintenance.
Also, thanks to LESB for providing the step file for Dyson attachments.
