What can I say I'm in love, and blown away at how amazing my new shark robot vacuum cleaner works!! I love the fact that I can activate it using the app linked on my phone to it having it clean whenever I want and from where ever I am to!! The robot vacuum cleaner maps your home so it learns as it goes making sure to clean all or the areas within your home and very well I might add. I'm honestly truly impressed with how advanced the technology is in this shark robot model vacuum cleaner.
