Dyson doesn't say removes dust than any other vacuum any more and it is now says cleans better than any other vacuum across carpet and hard floors and I asked Dyson what Machines is it tested against and he said they test many manufacturers and many machines what isn't allowed to i'm manufacturers. Dyson can't say any of his claims without proof has to be accepted by Industry standard They are the people that design the tests and approve everything and I do the Dyson DC 65 is tested against 98 different machines. Again Dyson is only recently perfected the Cyclone technology cyclones alone are allowed to filter out 0.3 of dust and allergens.
Dyson proves no loss of suction, best pick up, and 'overall outcleans other vacuums' using results from
IEC 60312 Cl 2.1, 2.2, 2.3, 2.8, 2.9, ASTM F608 and F558, and DTM 755— an independently conducted Dyson test."
To prove this our engineers test for pick up performance across carpets (ASTM F608), hard floors (ASTM F2607) and hard floors with crevices (IEC 60312-1 5.2). To mimic actual use, they load machines with dust before testing (IEC 60312 – 1 5.9).
Suction tested against upright market to ASTM F558 at the cleaner head, dust- loaded as per IEC 60312-1.
Tested against upright market, dust-loaded, using ASTM F608, ASTM F2607, and IEC 60312-1 5.2, 5.9.
1To prove this Dyson vacuum removes more dust our engineers measure pick up performance using test protocols IEC 60312, 2.1, 2.2, 2.3 and 2.9. At bin full DC41Mk2 Animal removes more dust in total from hard floors, carpets and crevices.
