Yep, and when it comes time to do a complete substrate change, I use a shop-vac (with the snake in a holding pen). I do complete substrate changes on an irregular schedule - if my nose says that it's time, substrate is starting to look meh (little bits of shed or other refuse that spot-cleaning can miss, etc.), or when a bunch of non-herp people will be visiting.
