iRobot Roomba Combo Robot Vacuum

It cleans hardwood, tile, and low-pile carpets well. High-pile carpets and thick rugs may be harder for it to handle.

Runtime is 120 minutes per charge. Actual runtime varies between 60 and 90 minutes depending on floor type and suction level. Most users report the vacuum finishes a full cleaning cycle before needing to recharge.

It uses smart navigation with mapping technology to clean rooms in neat rows. Sensors prevent collisions with furniture and stairs, and the navigation is reliable and efficient.

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.
