Here's the problem... I am STILL getting pee clumps over the end of the new lip. Its been three times since we put on the new lip. The first time was our fault though since hubby didn't realize you have to push the power button and I didn't realize he hadn't so the box was pretty damn full of pee clumps when I did finally realize and run it. There were so many, they didn't fit on the rake well and that was why the clump got shoved out. The others I wasn't in the room to see, so I have no idea why those two fell out; however, from watching it that first time, I had an idea. I am going to experiment first with bending the lip so it has a gentle curve back into the box which should help the clumps to roll back onto the rake. If that isn't enough, then I will add a bit of height to the lip along with this curve and hopefully that should do the trick. My cats have enough room to enter the box from the left side so the longer lip wouldn't be a problem for me.
The new motor seems much more powerful and just plows through the box. The old one sometimes got hung up on a single large pee clump and would reverse a few times before getting it. I am not sure how much difference the new rake is making since I am using Tidy Cat, but the box has been pretty darn clean and it does seem like I don't have to scoop broken clumps as much as before even with crappy litter.
Even with the few pee clumps getting rolled out, I am keeping this box and giving it 4 stars because cleaning them up takes me about 30 seconds and other then that, the box has been so much better than I hoped for. Clean up is so easy for me because I have two mats http://www.petsmart.com/product/index.j ... Id=3052369 next to each other in front of the box and if a clump gets out, I just pick up whichever mat it is on and roll it into the waste area and then shake the mat over the box, wipe the mat down and I am done. Even my standing up peer isn't making a mess with this box and all the cats except the feral (she just isn't seeming to get total litter box usage since the CG
I'll update after trying to bend the lip and give the results. Cross your fingers for me
