Reusable Sticky Buddy Lint & Pet Hair Removing Cleaning Brush 4 "It Does Work" Mr Caryl 11 February 2016 I have tried all of the preparatory brands for removing Cat Hair from carpets and chairs. This is the one!! What one must do is to use the Yellow Nippled part, using a scraping action is best. This will then pull the hairs from the carpet pile rolling it up, remove the rolled hair and depending on the hair of the cat(s) depends on how much pressure you need. Not as keen on using firm pressure on the extended handle "Buddy" so I unscrew it or use the medium one. Excessive pressure can chamfer the nipples but it does not affect the operation to a great extent. ! For under £15 it's well worth it!
