After seven months of hard work, part 1 of my self-cleaning litter box mega test is finally here! In this series, I look at these machines, comparing them to see which are the best. In this, part 1, there's the introduction of this series, and then there's the main chunk, a 6-month review of the Litter Robot 4. The machines featured in this series are Litter Robot 3, Litter Robot 4, Petkit Pura Max, Petkit Pura X, Popur X5, Lavviebot S, and Leo's Loo Too. Whisker, Smarty Pear and Popur sent review samples, which I am enormously grateful for, and the others I bought.
