Air watts measure suction in lab
conditions — but they don’t tell the whole story.
Air watts are a lab-based measurement of suction power taken under controlled conditions. They indicate how much air a vacuum moves and how efficiently it converts electrical power into suction. While that might sound important, it doesn’t reflect real-world cleaning performance.
Why?
Air watts don’t account for floor type, brush-roll design, or dust pick-up efficiency.
A vacuum with high air watts can still perform poorly if the airflow path, cleaning head, or filtration isn’t optimised.
In everyday cleaning, features like floor head design, dirt sensor technology, anti-hair wrap systems, and battery runtime have a far bigger impact on results
What to Look For Instead:
• Real floor cleaning performance – how well it picks up fine dust and larger debris from different surfaces.
• Battery runtime for floor mode – not just handheld.
• Ease of maintenance – simple bin emptying, washable filters.
• Weight and manoeuvrability – so cleaning feels effortless.
• Smart features – dirt detection, automatic power adjustment, and anti-tangle brush-rolls.
Bottom line:
Air watts might look impressive in specs, but for real cleaning results, focus on how the vacuum performs in your home, on your floors, and with your lifestyle.
