So many robot vacuums go on sale for Black Friday that decision fatigue is imminent — unless you're specifically set on a Roomba, that is.

Thinking of investing in a robovac this sales season? Here's how to narrow down your options, so you end up with the right model for you.

Head to Amazon right now and you can hoover up the Roomba Essential robot vacuum for $149 (was $249.99), or the combo vacuum-mop version for just $159 (was $274.99). That's 40% and 42% off respectively, and the lowest prices we've seen for both models – and these are ridiculously cheap prices for Roomba vacs.

Below, I'm tracking the robot vacuum deals live ahead of Black Friday. Deals are organized into two sections: robot vacuums that don't mop and robot vacuum and mop combos, with self-emptying docks noted when applicable. Within each category, all robot vacuum deals are ordered by price from cheapest to most premium.
