Litter-Robot verses Cat Genie? which one would be a better investment?

I have always been a cat person (but my hubby isnt) and i am left to deal with the litter box completely... well working on a second Bachelors and having twin 7 yr olds and a 2 yr old i just dont have time... also our house is small and we use every availible space except for my bathroom which starts to stink as SOON as the cat goes.... much less if i cant make it there quickly to clean it.... anyone out there have either of these products? ive seen them work on youtube and was wondering what people thought that actually used the products.... Thank you!!
