iRobot Roomba 104 Robot Vacuum

Users report the Roomba 104 picks up dirt, dust, and pet hair effectively on most floor types. Two-thirds say it leaves floors noticeably clean.

The battery runs for 60-90 minutes on a single charge, which is enough to clean an average-sized room before needing to recharge.

The Roomba 104 does not have smart features or app connectivity. It operates on a scheduled cleaning routine without mobile app or voice assistant integration.

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.
