Amazon is currently discounting the ECOVACS DEEBOT N79S robot vacuum, dropping it all the way down to just $159. That is a great price, seeing as the previous all-time low was $169. However, you do need to use the promo code ECOVACSN79S at checkout.
The ECOVACS DEEBOT N79S is a pretty cheap robot vacuum to begin with, but it is worth the price, even the regular price. This one does a really good job at cleaning, and even has a max mode, where you can double the suction, so that it gets up all of the dirt in your home. It does also map out your home, like the Roborock and iRobot vacuums that are nearly twice as much. This is so that it knows where it needs to go to clean, and where it has already cleaned.
There is also Amazon Alexa and Google Assistant support. Allowing you to use your voice to control the robot vacuum and tell it when to start cleaning. The app also works pretty well, with the ability to set a custom schedule and everything.
