This system beats Scoopfree and any other automatic system out there. In the long run, this is more cost efficient. Not only is the cost of the solution and replacement granules much less, we save by not buying all the deodorizers we've needed with other systems to mask the smells. Cleaning and maintaining other systems were tough on my back and knees. Now, I only occasionally wipe with a disposable disinfecting cloth (7th Generation brand is non-toxic) along the parts that aren't cleaned in the process - 1 minute of bending at the most! We had one error only when 1 of our cats ate some ribbon pieces which got stuck and stopped the cleaning process. We followed the first step of the error instructions, not too hard, and it worked! We love and highly recommend CatGenie!
