We can agree to disagree. This is based on experience with about 4 or 5 Shark vacuums since 2014-2015. Every Shark I had would start strong and then about a year or two in would noticeably drop off in power, and that's with frequent cleaning of the filters. It has hepa filtration and I'll give it that, but they're deliberately designed for when it goes out to go and spend another $200+ on one. The Navigator I got in 2022 is nowhere near as strong 2 years later. Does it get dirt still? Of course, but the airflow reduced significantly. This Dirt Devil sucked up more than just whatever had been left behind and has 10x the airflow at the nozzle because of how hard it sucks down to a thick low pile carpet. A whole clump of sand and grit that filled the bottom of the container. This Dirt Devil has a filter above the cyclone where the clear housing is. The brush rolls on this vacuum is also removable for maintenance, where the Shark has several torx screws in place so people can never actually repair their vacuum. We had to throw out my grandmother's Shark Speed because the bristles evaporated. I would say, The Bissell Powergroom I had fits your description better, it was nowhere near as powerful. All it did was such up carpet fibers and little if not no real deep sand and grit, and that was NEW out of the box. There's a YouTuber who found his 03 Featherlite Vision picked up grit that the latest Dyson of the time with modern tech failed to get.
