Query: Best litter box on the market

I have been using the regular size of this product and after wasting about $700.00 on Litter-Maid automatic cat box the Litter Robot LRII winds hands down. When your cat uses the unit it rotates and cleans the clumps from the litter and dumps it in a drawer under the unit. It is well built with a heavy duty drum and motor unit. If something dies you can get parts so you do not have to purchase a new unit. The people I have worked with at the company are wonderful and if you have a problem they are there to help and this is obvious right from the beginning.One thing is they cover the entire unit for 18 mounts so you do not have to have a unit that dies the day after the unit fails. I am a breeder and tried the Litter Maid, total wast of money as they die within the 13th month which is 1 month past the warranty plus if you happen to have a failure before their warranty ends it is like pulling teeth to get a replacement from Litter Maid.
