I used to use a shop vac with the special horse attachment put on the end. After that one died I switched to one of the big horse vacs and it does have more suction than the shop vac does. However, my trainer has one of the small portable ones for shows and it does a good job, but once again isn't as strong as the large horse vac. I love them, though, and they save so much time it isn't even funny. Especially when you're showing showmanship.
