For pet hair, look for vacuums with strong suction (minimum 20,000 Pa for robot vacuums, 150+ AW for cordless), specialized pet hair attachments, and HEPA filtration that captures 99.97% of particles.

Most vacuum filters should be replaced every 3-6 months, depending on usage frequency and household conditions. HEPA filters typically last 12-18 months with regular cleaning.
