iRobot Roomba i3+ EVO Vacuum

The battery lasts around 90 minutes of continuous cleaning before needing to recharge.

The i3+ EVO cleans hardwood, tile, and low-pile carpets.

With the Clean Base Automatic Dirt Disposal, the i3+ EVO empties itself into a bag that holds up to 60 days of cleanings. Without the Clean Base, you'd need to empty the dustbin after every cleaning or every other session, depending on debris collected.

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.
