On hard floors, the Shark AV911S should work fine. It has no problem removing larger items like cereal but has trouble with smaller items like pet hair and rice. It is sturdy, runs for a long time on a single charge, and has a number of automated features (including a dustbin that empties itself) to choose from. Sadly, there are a lot of moving parts that need to be cleaned frequently. There are also substantial ongoing expenses due to the frequent necessity of component replacement. Additionally, it can do a decent job of navigating itself, but it occasionally identifies objects like electrical cords as obstacles to be avoided.
The Shark AV911S can handle a wide variety of cleaning tasks. You won’t have to empty the vacuum by hand when it fills up because, like the i7 model of the iRobot Roomba, an external dustbin is attached to the docking station. It delivers good performance on bare floors and does an impressive job of cleaning high-pile carpets. However, even compared to other robot vacuums, it has high ongoing costs and demanding maintenance needs.
Both the Shark EZ Robot Self-Empty AV911S and the Shark AI Robot have their benefits, so you’ll need to decide which one is best for you. The EZ’s superior performance on low and high-pile carpet is especially noticeable when dealing with pet hair, and the enlarged capacity of its dirt compartment is a result of its external dustbin. In contrast, the AI has lower maintenance costs, requires less frequent cleaning, and can move around obstacles like cords with ease. Additionally, its companion app allows you to create virtual boundaries that the AI will not cross.
