The Dyson claims to have the most suction of any vacuum and the Shark Apex is sharks most powerful vacuum with a huge upgraded motor. you can see my individual videos on each of these.
So lets get to the tests.
#1 The Crevice Pickup Test
The Crevice pickup test is a test that Dyson has used in the past to demonstrate its suction power. Most of the early sharks have failed this test. The Dyson, as expected does great, it grabs the 1/8 inch crevice in one pass, and the 1/4 in 2 passes, finishing in 6 passes.
The Shark Apex gets the job done in half the time at 3 passes, and even though there is a little margin for error with this test, we will give the point to the shark Apex.
#2 Suction Test.
I tried a few different ways to get suction measurements and I got identical numbers each time, lets call it, 96 inches of water for both units, which is surprising that the Sharks are finally rivaling the Dysons in this category. For context the older Sharks measure about 78 inches of water.
So we will call this one a tie, no points awarded.
#3 The Big Mess Test
This one was a big surprise, The Shark Apex soundly beat the Dyson in two separate big mess tests. The self adjusting plate on the Dyson is great for suction but severely limits the size of the debris it can pick up
#4 and #5 which were the side cleaning and suction proximity test were too close to call so no points awarded.
#6 Thick Carpet Test
The final and most crucial test was the thick carpet test. For this I vacuumed a somewhat dense rug to see if the vacuum would bog down.
The Dysons suction made it impractical to vacuum the rug as it was just too difficult to move, we are hoping for an adjustable suction feature on future Dyson versions.
The Shark handled the thick rug with no noticeable change, we didn’t even have to use the adjustable suction. So another point for the Apex
