Brushless vs brushed motor vacuums: Brushless is the only sensible choice for long-term performance

Brushless motors maintain full suction for years — one has been running daily for three years and still picks up like new. Brushed motors lose power after a year and may need replacement by 18 months due to physical brush wear. When comparing similar vacuums, pick the brushless one; you’ll notice the difference in month eighteen, not month one.
