Intelligent Self-Leveling and Boost Mode.
The Tools We Used: A Real Suction Gauge.To measure actual suction, we used a proper analogue vacuum gauge — not a cheap airflow meter or a vague app.
Our test gauge is.a specialist Marshall Town model.from the United States, normally used to measure water lift.
It’s a trusted bit of kit among professional reviewers, and it’s the most accurate way to assess suction strength directly at the hose..These gauges aren’t easy to get in the UK.
Ours was sent by our friends over at the Vacuum Wars YouTube channel in the US, who kindly supplied a few for testing purposes — not cheap once you add import duties and VAT, but worth it for getting proper data.
Most Powerful Sebo: The Machines on Test.Not self-levelling like it used to.
