roborock S8 Pro Ultra Robot Vacuum

Users report that the S8 Pro Ultra picks up pet hair well across different floor types. Two-thirds of owners say it handles their pet's shedding with ease.

The S8 Pro Ultra runs for approximately 2-3 hours on a single charge before returning to the dock to recharge.

The S8 Pro Ultra operates at a moderate noise level, similar to other robot vacuums. Most users report the noise doesn't interfere with normal household activities.

For pet hair, look for strong suction (roughly 20,000 Pa or more on a robot vacuum, 150 AW or more on a cordless), a tangle-resistant brush roll, a dedicated pet tool, and HEPA filtration, which by definition captures 99.97% of particles at 0.3 microns. Dyson, Shark and Bissell all make well-reviewed pet models. Use the Pet Hair Specialist filter on our comparison table to see which ones are in stock and what they cost right now.

Most manufacturers suggest replacing filters every 3 to 6 months, depending on how often you vacuum and whether you have pets. HEPA filters usually last 12 to 18 months if you clean them regularly. Washable foam filters on bagless models should be rinsed every 1 to 2 weeks and dried fully before going back in. Replacements typically run $15 to $50. A clogged filter chokes airflow, so suction drops noticeably well before the filter looks dirty.
