OH MOST DEFINATELY!!
I dont think i can praise this machine anymore. I have 2 1/2 cats (the one is only 12 weeks old) and I can let the device go a week without having to change the bag and you still wouldnt know there were cats in my apartment. I absolutely adore this machine.
I even found one on craigslist that the guy was selling for $75 and he was 3 hours away....you damn for sure I was there so now I have 2 of these Robots and I dont think I could ask for anything better. I do use Worlds Best cat litter and I can say a 17 lb bag is lasting twice as long as it would of in regular litter boxes.
The only bad thing I can say is that because I am a light sleeper if the Robot cycles during the night it does wake me up, but heres the good thing, you can unplug it so it doesnt cycle during the night. I dont like to unplug it because i would rather be woken up by the Robot cycling than one of the cats smelly butt.
Definately definately invest the money it this, you will love it as much as I do!!
