I took the plunge and put down the not inconsiderable price for the Litter Robot. It works great. I timed it so I got Harry and the Robot at the same time and I've had no problems at all. I put him in the robot so he would know what it was. Once he felt the litter he decided to dig to China so the covered box kept all the litter inside. When he finished his business I plugged the Bot in so it would start it's automatic cleaning cycle. (Until Harry is over 5 pounds I'll keep it unplugged because the automatic sensor doesn't detect under that weight) Poop went into the lined waste tray and that was it. The tray also has a carbon filter for added odor control. I also put baking soda in the bag to increase the odor control but I'm also very sensitive to scent. At the end of the week I'll take out the bag and never have to touch the poop. Some mentioned it being noisy but I hardly notice. I live in a small apartment and can easily ignore it. Compared to Harry's "talking" it's nothing! Also, I don't know how Harry compares to other cats, but I've noticed very little litter scatter when he jumps out of the box.
