Verdict

The Shark AV2501S AI Ultra is a mid-range robot vacuum featuring 360° LiDAR navigation for precision home mapping, Matrix Clean technology for multi-pass grid cleaning, and a 120-minute maximum runtime with recharge-and-resume capabilities. Main advantages include a bagless, self-emptying base with true HEPA filtration that traps 99.97% of allergens and holds up to 30 days of debris, combined with a specialized self-cleaning brushroll that prevents hair wraps. However, notable drawbacks include companion app software limitations that lack real-time tracking, an inability to save multi-floor maps, and a smaller station dustbin capacity compared to the 60-day limits of related models.
