Do you groom your Cavalier?

I found a great video on grooming your cavalier. Do you prefer keeping your cavalier with all of his or her natural grown hair, grooming him or her yourself, or bringing him or her to the groomer?

I grew up with a cocker spanial name Brittney.  My Dad always cut her himself.  She did not look like the other cocker spaniels, but she is a lot easier to keep clean.  Here is a picture of Charlie and Brittney together below:
