NARWAL Flow Robot Vacuum

Users report thorough cleaning across different floor types, with strong pickup of dirt, dust, and debris. The 22,000Pa suction and CarpetFocus technology handle both hard floors and embedded carpet dirt.

Battery life is 90-120 minutes on a single charge, enough to clean most homes before needing to recharge.

Users find the noise level low enough that it won't disrupt normal conversations or activities in the home.

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.
