Automatic Litterbox Central

Which clumping cat litter do you use with the Omega Paws Litterbox? Do you recommend any particular brands? What is the easiest way to completely clean out the litterbox when changing out the cat litter? Has anybody tried to use kitty litter box liners? Thanks in advance.

I started out with Arm & Hammer and it worked well... but my kitty is having sinus problems, so I'm testing out other litters to see if the dust is a factor. I'm using WBCL now and it works fine with the Omega Paws, also.

I have not used liners and when I completely clean the box out, I have to take it apart. Fortunately I only have one cat so I don't do this often (as of now, like every 6 weeks)...though I've only had my cat for 2 months!
