Spas are a piece of cake in my opinion...the key is to actually sit down and take the time to learn proper maintenance, and then actually taking the time 2x-3x a week for 5-10min. to check on the tub and balance and/or add chemical as needed. And yes spa vacs are a simple device used to pull small dirt/debris from the bottom of the tub, most of them are cheap ($35-$75) and can be found online and mostly likely at local dealers as well
