Pet owners of hairy dogs make it a habit to both vacuum attentively and brush their pets profusely. Dyson’s new Groom Brush accessory for your vacuum cleaner makes a good case for combining the two steps into one.

It works like any standard wire pet brush, but when you’re done you retract the teeth and any hair that was gathered is vacuumed. That doesn’t make much sense, unless you’re a pet owner, and you know how hard it is to get a dog close to a working vac.

At $90, it looks solidly built and safe.
