We had been brushing our Golden Retriever every 1–2 weeks but were still getting an excessive amount of fur on the carpet and clothing. After a 10 minute session with this tool we couldn't believe how much lose fur the other brushes just weren't picking up. It did an amazing job and dramatically reduced the amount of fur on our carpets. It's expensive, but designed to last for 10+ years. Now, brushing every 1–2 weeks we get much less fur from her but it's still more than with the old brushes… and now the vacuum is able to cope a bit better :)
