A vacuum with a powerful motor can still clean poorly.
Why? Because suction is only one part of the system.
A vacuum depends on steady airflow through the floor head, hose, filters, and dust bin. When that airflow is restricted, cleaning performance drops—even if the motor is still working normally.
Common causes include:
✅ Clogged filters
✅ A blocked hose
✅ An overfilled dust bin
✅ Air leaks around seals
✅ A brush roll packed with hair
From an engineering point of view, the best vacuum is not always the one with the highest advertised power. Brush design, airflow efficiency, filtration, floor type, and maintenance all affect real-world performance.

What matters most to you in a vacuum: stronger suction, better filtration, or a better brush roll?
