The Dyson 921000-02 Groom Tool has two rows of slicker bristles that angle at 35 degrees to grab loose hairs and penetrate the entire coat. With one-handed thumb pressure, you can extend or withdraw the bristles. By removing your thumb from the spring trigger to pull them back into the tool the bristles are protected from damage during storage. This tool has enough suction to capture dead skin cells without the tool sticking. This prevents the spread of allergens, and helps make your dog look healthier. To control the bristle length, just push down or lift your thumb. This action allows you to control the pet with the one hand and lets you switch between grooming and self-cleaning modes with the other hand.
The Dyson Groom Tool is ideal for most Dyson upright or canister vacuums but isn't designed for handhelds.
