If you've been wanting to buy a robot vacuum for your home, this is your chance, because 3i has big discounts on its best products for Prime Day.

Our top pick for a more versatile robot vacuum, the Eufy E20, is an impressive $270 off for Amazon Prime Day. The Roborock Qrevo S, which we consider the best overall robot vacuum, is 38 percent off, saving you $300.

Every year during Prime Day, we see waves of robot vacuum deals, bringing the often-lofty price tags down to a more manageable level. For example, right now you can save $500 on the Dreame X50 Ultra Complete, now $1,299 (was $1,799) at Amazon, while in the UK it's now £899 (was £1,199) at Amazon.
