Damp rubber gloves work quite well at removing fluff. I tend to wear different clothes (gardening scruffies) when doing a full grooming session and vacuum up immediately afterwards, then change clothes. Brushing them outside when there is a slight breeze also gets rid of the loose fluff a bit more - not recommended this week, though. Also depends on how furry you like your garden to be - it sticks in the twiggy bits of shrubs, but the birds use it for bedding.
