The iRobot Roomba 105 has plummeted back to its lowest-ever price of $169 at Amazon. This allows you to save $150.99 off its usual price of $319.99. If you're hoping to grab it ahead of the holidays, Amazon even has a note on its sale page that states it'll arrive before Christmas to give you a little peace of mind.

While iRobot is selling itself off as scrap, let's remember what actually makes a good robovac.

The original Roomba was the first robot vacuum in the US, and the second ever made, following Electrolux’s Trilobite the year prior. A basic bump-and-roll bot with bump and cliff sensors, the Roomba rolled randomly around your home, sucking up dirt, bumping from wall to wall, and generally trying not to fall down stairs.

iRobot, the company behind the Roomba vacuum cleaner, is seeing its stock on little actual news. Retail traders think they smell a short squeeze.
