The blackest of Fridays is nearly upon us and companies have already begun rolling out the deals to separate consumers from their bank accounts. The iRobot Roomba Essential Vac is on sale for just 140, which is a discount of 44 percent. The regular price is 250. The Essential Vac features a similar design to the iRobot Roomba 694, which topped our list of the best budget robot vacuums. This one includes a three-stage cleaning system that works on both carpet and hard floors.

While robot vacuums are quite helpful, they can be rather expensive. If you've wanted to try one but you're reluctant to drop hundreds on a name-brand model, today's your lucky day. The Lefant M210 robovac is down to 89 at Amazon, an incredible savings on the robot's list price of 200. It's rare to see robovacs under 100, especially ones that don't compromise on performance! Designed with pet owners in mind, the Lefant M210 tackles pet hair and dirt as it operates its effective zigzag cleaning routine.
