很窄但是大容量的竹屎盒，节约空间，如图二所示并排放置a1系列时几乎不占用额外的空间。一体结构，不会因为机器晃动而产生噪音。

The very narrow but large-capacity poop collector saves space, and it hardly takes up extra space when placed side by side with the A1 series as shown in Figure 2.The one-piece structure does not cause noise due to the shaking of the machine.
