We put several robot vacuums from Roborock, Eufy, Dreame, and more through a series of mess tests to see which stood out.

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.

If you’ve been waiting for a sign (or just a really good discount) to upgrade from your old robovac, this is it.

This smart robot vacuum saves time by vacuuming and mopping together, making daily cleaning easier for busy households.

SAVE 56%: As of Dec. 15, the 3i G10+ robot vacuum and mop combo is $199.99, down from $449.99. That's a 56% discount or $250 in savings.

I've tested robot vacuums of all shapes, sizes and price-points, and with all kinds of specs. But how much suction do you really need in a robot vacuum, and what kind of specs should you look for? Robot vacuum suction is measured in Pascals (Pa).
