iRobot Roomba Combo j5+ Self-Emptying Robot Vacuum

The suction power picks up debris and dirt well on a variety of floor types. Some users note it may struggle with deeper or heavier debris.

Battery life is approximately 90 minutes on a single charge. The vacuum returns to its charging station automatically when the battery runs low.

The self-emptying feature works well for most users, automatically emptying the vacuum's dust bin into the larger base bin. Some customers have noted occasional issues with the mechanism.

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.
