​Why is the percentage of remaining litter shown in the APP inaccurate?

Cat Litter Percentage

Due to the different density of cat litter, the APP may show that the remaining cat litter is 100% if the cat litter reaches the standard weight, even if it does not reach the MAX line in the cylinder. Please refer to the actual capacity of different cat litter: 12.8 lbs clay cat litter, or 7 lbs tofu cat litter, or 7.9 lbs mixed cat litter. Please do not exceed the maximum weight of cat litter, otherwise clean litter will be filtered.
