Powerffy Cordless Vacuum

Runtime depends on the mode. ECO mode runs up to 65 minutes, MID mode runs 30-40 minutes, and MAX mode runs 15-20 minutes. The vacuum comes with eight 2500 mAh batteries.

The Powerffy Knight 10 weighs 4 pounds, making it lighter than most full-featured cordless models and easy to maneuver and carry up stairs.

It cleans hardwood floors, carpets, and upholstery. The 50 kPa suction handles both hard and soft flooring, plus embedded dirt and pet hair.

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.
