Dyson Twice The Suction with James Dyson
In this commercial James Dyson explains why his invention the Dyson Ball is twice as good as other vacuums.
What James Dyson says:
At Dyson it’s our inventions that set us apart. Other vacuums can’t pivot on a ball, adjust automatically for carpet and hard floors and quickly release like ours for easy cleaning. We invented and patented a unique Root Cyclone technology, created a hand tool that won’t tangle up inside and a bin that empties this easily. Crucially, ours has twice the suction of any other vacuum.
Claims that James Dyson made and what they really mean:
- What James Dyson said: ..ours has twice the suction of any other vacuum
- What some people might think that means: All Dyson vacuums have twice the suction of any other vacuum
- What it really means: When this claim is made, the following extremely small and almost impossible to read fine-print is shown:
Suction tested against upright market to ASTM F558 at cleaner head, dust-loaded as per IEC 60312-1
Everyone knows what ASTM F558 is and of course we’re all familiar with IEC 60312-1, right? Don’t worry, read on!
What is ASTM F558?
The fine print in the ad refers to ASTM F558 but the average American probably has no idea what this is. ASTM F558 is standard published by the American Society for Testing Materials which specifies a very specific method or protocol for testing and measuring suction – more specifically, it is the “Standard Test Method for Measuring Air Performance Characteristics of Vacuum Cleaners“. Using the ASTM F558 gives all vacuum manufacturers a fair, standard way to measure their suction.
What is IEC 60312-1?
IEC is the International Electrotechnical Commission which, similar to the American Society for Testing Materials (ASTM) has a published standard way for testing vacuums. The IEC 60312-1 is a 62-page document that describes methods for measuring vacuum cleaner performance (how much dirt it picks up, etc). From the IEC 60312-1 document:
This International Standard is applicable for measurements of the performance of dry vacuum cleaners for household use in or under conditions similar to those in households. The purpose of this standard is to specify essential performance characteristics of dry vacuum cleaners being of interest to the users and to describe methods for measuring these characteristics.
Do Dyson vacuums really have twice as much suction as any other vacuum?
The fine print on the commercial shown above only discloses what tests and standards were used to determine and substantiate the claim that Dyson vacuums have twice as much suction. The fine print does not tell us which vacuums were tested. Upon further review of the Dyson.com website, we can find the following additional disclosure:
DC41 has twice the suction power of any other vacuum
Dyson sells 8 different models of vacuums, but according to the disclosure on the Dyson.com website above, only one model, the DC41, is shown to have twice the suction of any other vacuum.
Some people may feel that when James Dyson said “ours has twice the suction of any other vacuum” that he is being very deceptive, and making a deliberate attempt to lead viewers to believe that every Dyson vacuum has twice the suction of any other vacuum, which according to the Dyson website, is not the case.
