LG Cordzero Q3 Cordless Stick Vacuum

The LG CordZero Q3 runs up to 60 minutes on a single charge in normal mode. Most users report they can clean their entire home on one charge.

It weighs 5.73 lb, making it easy to maneuver and carry around the house.

The LG CordZero Q3 has powerful suction and advanced filtration for dirt, dust, and debris on various floor types. It cleans well on both hard floors and carpets.

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.
