Too often, we take the technology of today for granted.

Imagine, as a thought experiment, presenting an iPad to any American from the Civil War era. Or gifting a home security camera to an Ancient Egyptian. Or a laptop to J. Robert Oppenheimer, from the movie (amongst other things).

One invention we still haven’t gotten over yet, however? That’s the robot vacuum, popularized by iRobot’s Roomba brand. Consider this: explaining to someone just 25 years ago that by the year 2023, it’s not out of the ordinary to leave the cleaning to a little round robot that would cause any 1998 denizen’s head to explode.

And while the invention itself isn’t enough to knock the wind out of us anymore, the price of an iRobot Roomba i4 EVO this week is low enough to make our eyes pop out of our heads.

This week, you can snag an iRobot Roomba i4 EVO for a whopping 42% off on Amazon, lowering the grand total for this robot vacuum to just $209.99.

Compared to other Roomba i-series robot vacuums, the iRobot Roomba i4 EVO has a 20% larger battery, meaning longer runtimes, and cleaner floors. Simply allow the Roomba to familiarize itself with your home, press a button, and relax, all for just $210 today on Amazon.
