What every best has:
Susan Tauber tests the Shed Vac on her two Labrador retrievers, who shed so much that she has to vacuum twice a day. The device is gentle and doesn't bother either dog; they seem to enjoy the vac's massaging action. However, after comparing the Shed Vac with another de-shedding tool called the Furminator, Tauber says the Furmintor picked up a lot of hair that the Shed Vac left behind. She concludes that the Shed Vac doesn't pull enough hair from the undercoat to really solve a shedding problem. "It stirs up the fur but doesn't really do a deep cleaning, which is what causes shedding," Tauber says.
Lance Barry, a volunteer tester, tries the Shed Vac on his Labrador retriever. The loud motor scared the dog, and she kept running away whenever the device was turned on. The Shed Vac does collect some hair, but reporter Suzanne Murray questions its claim to have a calming effect on pets, considering how loud it is.
About 30 owners rate and review the Shed Vac here, and most say it's junk. They complain of flimsy construction and inadequate suction, or say it scares their pets. A few say they're happy with the Shed Vac; even satisfied owners say it took a while for their pets to get used to the noise, however.
Although the Shed Vac earns a perfect 5-star rating, no testing is documented. This seems to be an affiliate site for the products reviewed, not a true testing site.
