We tested 4 of the best selling Shark vacuums to find out which has the most suction. Amazon links in the description to all the sharks tested here.
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.
First up was the Navigator 300 series and the Rotator 500 series, they are older but very popular models even today and actually have the same size motor, but despite that our tests showed the NV352 has 29% more suction than the Rotator.
So the Nv300 series is the Shark to beat.
Up next is our favorite Shark so far the NV800 series specifically the NV803 with duoclean, the motors were upgraded around the 600 series so we expected this one to beat the 300 series and it did.
Scoring 69.9 cfm which is 24.9% more suction than the 300 series so it takes the lead.
Last up was the Shark Apex, the Apex 951 and 952 has the largest motor of any Shark vacuum to date even larger than the Apex Speed Ax912 which we haven’t tested yet, but confirmed with Shark does have a smaller motor than the full sized Apex.
The Apex Scored 86.8 cfm which is 22% more suction than the 800 and a whopping 73% more than the NV501, meaning it has the most suction of any Shark vacuum to date.
