The Bubble Bot Rug medium-sized circle rug of a dark blue Bugdroid behind light blue bubbles. There were two large (6") variants made, one of them was for Andrew Bell personally and one was sold to the public for $550.
This rug and its larger counterpart are the most expensive merchandise to be sold. 
Protect your bare floors! This durable Bubble Bot Android rug looks great in any room, is an awesome entryway shoe mat, and pets love sitting on them (I know from experience!). Luckily they are both durable and easy to clean.
