Shark Navigator Robot Vacuum, with SmartPath Navigation and Self-Cleaning Brushroll, RV2110

So glad I ordered this product! It is not the most expensive but certainly the most affordable. i learned how to operate by cleaning sections of my home versus a full clean for the most efficiency. Drawback: while not provided in the online description, instructions recommend replacing filters and roller brushes every 30 days. these parts are not available from Shark. I ordered spares thru a third party, and after 30 days, I am still using the original by cleaning after each use. Still very pleased with my purchase. My single story cleaning area is about 1500 sq ft of luxury vinyl flooring. The Shark detects changes in flooring to accommodate cleaning the rugs in entryways. It navigates around or under chairs and furniture. To achieve a more thorough cleaning area, I move these objects out the way. While it may not be faster than sweeping the floors manually, I feel the Shark gives me time to relax. My pets are curious but do not attack, bark or ride.
