Litter Robot 3 "open-air"
Bought one. Not sure about prior models, but it is okay. Doubt I
would have liked the preceding models' small openings. With the
current model you can easily wipe off the inside, so you can
remove the shield, giving them a little more room inside.
Mine slightly bobs up and down as it cycles. I guess the gear or
the motor shaft is out of alignment. But it works.
Using Arm & Hammer Clump & Seal. Without having used the prior
models, I suspect complaints about the waste bag holder are
correct. But it probably can be modified.
So far, it is fun, but will see how it does after many more
months of use. Longevity is the question.
