Pros Great value, excellent cleaning abilitiesGreat at picking up pet hair, cleaning carpets, doesn’t miss spotsGreat home coverage, excellent navigation, automatically empties its dust binFantastic at cleaning hard and soft floors, packed with smart featuresAmazing at navigating, covers all of your home, solid smart connect ability
Cons Good, not great at navigatingExceptionally expensiveExpensive, struggles with pet hairPricey, struggles at navigating in confined places, little rough on furnitureSo-so carpet cleaning skills, below average at cleaning hard floors, poor at picking up pet hair
Bottom Line The D4 is the best choice by far if you are shopping on a budget but don’t want to sacrifice performanceIf you want a top-notch robot vacuum that can handle pet hair with ease, then the s9 is a fantastic optionOffering excellent home coverage and navigations skills, the **i7+** did very well across the board -- except when it came to pet hairWhile this robot struggled cleaning around the tighter spaces in your home, the cleaning power of the D7 can’t be beatWhile this robot handles complicated room layouts with ease and practically never needs assistance, it might take two passes to get your home acceptable clean
