What is the difference between a “Grandi-Brush” or grooming brush and a “Grandi-Groom” or grooming rake?

• A carpet rake like the Grandi-Groom carpet rake has fewer bristles but they are longer and firmer.
• The Grandi-Brush has shorter and more bristles than a Grandi-Groom Rake.
• Use the Grandi-Groom carpet rake on anything over a 1/2 inch pile and the Grandi-Brush grooming brush for anything under 1/2 inch.
• The Grandi-Groom is best suited for Saxony, shag and frieze style carpet, while the Grandi-Brush works well for plush carpet like velvet.
• The Grandi-Brush is best for grooming where carpet rakes are too harsh.
