OKP K3 Robot Vacuum

The OKP K3 runs for around 100-120 minutes on a single charge, which is enough to clean most small to medium-sized homes before it needs to recharge.

The OKP K3 cleans well on both hard floors and low-pile carpets. It picks up dirt, dust, and pet hair during its cleaning cycles.

The OKP K3 operates at around 55-60 decibels, so it won't disrupt normal household activities while cleaning.

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.
