The ECOVACS DEEBOT N79S is a great robot vacuum for a few different reasons. Primarily because it works with Amazon Alexa, so you can use your voice to control the vacuum when you want it to start cleaning and so forth. Of course, you can still use the ECOVACS app that is on your smartphone (works with iOS and Android). The N79S can be programmed to start cleaning at specific times, as well as on specific days. So you can set it to start cleaning overnight (it's pretty quiet), and wake up to a clean home. The ECOVACS DEEBOT N79S is able to clean up pretty nicely. It has some good suction power included, so you are able to get up all of the pet hair in your home, in case you have someone that's coming over that might be allergic to pets. It also has a fairly large dirt container included so you won't need to empty it as often as you might think.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast.

You'll get 30 days free (if you're a student, you get 6 months), and then it's $119/year (or $59/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
