The amount of grooming can depend on the breed, lines, and individual rabbit. Angoras should have the coat blown out, rather than brushed. Brushing does remove wool, which isn't ideal. The blower opens up the coat, removes dander, and can keep the rabbit in good shape, brushing is usually reserved for the face, feet, and other areas that are harder to get with the blower. Daily grooming is usually not needed, weekly is usually good fro those with a nice coat. The coat does need to be clipped or plucked, which can be a lot of work. What what I have heard, it is usually younger rabbits that are shown, and once they are clipped, they are usually not shown too much more. It can depend on the breeder, but a full show coat can take 8-10 months to grow and be nice, so it's a lot more work. For wool, they are usually clipped every 3-4 months.
I am not sure I would recommend an angora as your first show rabbit since they are a lot of work compared to some other breeds. Do make sure to do more research and talk with angora breeders.
If you really aren't up for the grooming, then buy some wool if that is what you want. You could keep an angora for the wool, since that is a bit less work than a show coat.
