I had the Navigator until I bought the Shark Vertex last Black Friday 2023 at a price I couldn’t pass up. Gave the Navigator away after using the Vertex because I knew I wouldn’t be using anything else. It was the best vacuum I’ve ever used. The brush motor suddenly stopped working two weeks ago and I found myself buying the Powerdetect duoclean. I’m pretty sure this thing is sucking up dust from underneath my foundation because there is no way my beloved Vertex missed this much. I was vacuuming underneath my couch and paused while picking up a toy I missed. Pretty sure it sucked up stuff I hid under my bed 20 years ago from my childhood house 20 miles away. Husband said our 3 year old carpet is fluffy again and feels better walking on it. I’m not mad my Vertex red lighted me anymore.
