We tested direct suction, airflow at the hose and airflow at the floor nozzle. Though I tried to keep everything consistent Im sure there is some margin for error with my tests so take them with a grain of salt.
You can see all the results in the description, but for brevities sake I will just quote the Airflow at the hose measurements since it is the most indicative number and I am not 100% sure I got a good seal with my floor nozzle results, but they were at least consistent with one another.
For control purposes we tested 2 less expensive vacuums the Shark Rotator NV501 and the Navigator Nv352 getting 40.6 cfm and 54.4 cfm respectively.
Next up was the Miele Dynamic U1 Maverick, which has Miele’s 1200 watt motor. It showed 67.3 cfm which is 49% more suction than the Nv501.
Next we have one of our favorites, the Shark 800 series with Duoclean, It has a larger motor than the previous generations of Sharks and It scored 69.9 cfm, knocking the Miele off the leader board, but only by 4%
The Dyson Ball Animal 2 was next, and it claimed to have the most suction of any vacuum when it was released, it takes the lead here with 73.5 cfm, knocking off the Nv803 by having 5% more suction.
Finally we have the Shark Apex, which has the largest motor Shark has put in a vacuum to date and it shows, scoring a whopping 86.8 cfm which beats the Dyson Ball animal 2 by 17% meaning that it has an astonishing 72% more suction than the Nv501.
The Airflow tests at the cleaner head and the straight suction test generally mirrored these results, Links and results in the description You can see our full reviews of these vacuums on our channel, consider a like or a subscription if you enjoyed this test.
