iRobot Roomba s9+ Vacuum

Most owners report strong suction that picks up dirt, dust, and debris effectively on both carpeted and hard floors. Two-thirds of users specifically note that the suction power is strong enough to thoroughly clean both surface types.

Battery life runs between 60 to 90 minutes on a single charge. Most users find this sufficient to clean a large area of their home before needing to recharge.

Most owners describe it as quieter than traditional upright vacuums. A small percentage of users have noted it can be somewhat noisy during certain cleaning cycles.

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.
