I have hardwood floors throughout my home, 2 dogs and 3 kids. This Shark vacuum is heaven sent. It is quiet enough to run while my kids are napping, it doesn’t bulldoze into my dogs food because of its sensors. The app is great! It mapped my floors on the first use and got more and more accurate with each use. The app has a cute little feature to even name your new robot family member. 
The floors were extremely clean following the third run and i have officially gifted my old “other” brand vacuum shark to a family member. This is a great vacuum and highly recommended !
