Though I think it is a particularly useless metric other than for testing to see how well a machine can run an air-powered turbo nozzle, I noticed that certain UA-camrs on here (especially one) like to assert the "working vacuum" number, yet the user(s) who tout those numbers seem oddly biased against these Kenmore machines. Because of this and the impressive airflow and suction of the 31150/BU1017/BU1018, I made my own gauge and I found that this model gets around 60 inches of "working vacuum," with a close second (of the ones I tested) being the Kenmore 31140, which got about 55" if I remember correctly. In other words, they blow any Miele, SEBO, Henry, and so forth out of the water according to their logic and it brings me a lot of joy.
Suction measurements are mostly useless as suction is a negative pressure that isn't a speed or volume. Performance Reviews has no idea how to measure vacuum performance, which is ironic considering his channel name.
Nice test! 106 CFM may be a record for 2nd-highest bypass airflow, right behind Blackheart's Ultra MVP. As for the bags, I think the slightly lower airflow from the Kenmore bag has to do with the numbers of layers of filter material - genuine Kenmore O bags are the best quality I've found for filtration and durability. Also, the lower brushroll RPM isn't so bad when you consider how beefy the roller is - a larger diameter roller means higher linear speed at the bristle tips, and thus the bristles hit the carpet at a proportionally decent speed.
My 100 cfm Vorwerk has been beaten👍 Although I bet this can use all that airflow due to the large cutouts in the bottom unlike the Vorwerk what is very hard to push on the max power setting. It will be interesting to see how well that low rpm brushroll does in the pick up tests.
On a Riccar, the inducer motor causes the CFM to rise (rather than drop) when the brush-roll is enabled. Is this because the inducer motor on the Riccar is an actual direct air motor? They claim to have 2 motors on the Kenmore 31150 Is this counting the brush-roll motor?
I think this machine uses 2 motors like the riccar tandem air vacuums if I remember right. But this has much better airflow so I think it might have a possibility to pickup better in my opinion. 👍
@@VacLab our 60 horsepower hot water extraction system is set for 15 inches of lift. That's plenty for our industry. We run 2 inch to 2.5 inch hose at 650 cfm.
A company called Cleva makes the Kenmore models now; though I am sure they are contracted to other companies (such as KingClean) to some extent that I do not know.
Nice vacuum cleaner with great airflow tests. Slightly lower than my Anniversary Edition Wind tunnel. Unfortunately, what happens two years down the road when the brush roll needs replaced? Thats the gotcha at 200 bucks if they would still be available. After all no more Sears and Panasonic left the NA vac market. Thats more than half the cost of the cleaner. Pretty expensive brush roll. Dont see where the direct drive adds anything but increased repair costs
Replacing the brushroll is far too expensive in this model. That's why I grabbed another one for $9 a few months back. It came with a full toolset as well.
Hate to break it to you, but CR has never been a good source for vacuum recommendations. Their testing methods are weird and don't consider things like reliability and overall usability well. You're better off doing research based on people in the vacuum community like VacLab, and coming to your own conclusion from that. CR just got lucky when they recommended these Kenmores.
@@lacking4290 I used to subscribe to CR for their vacuum reviews. Sometimes I agreed with them and sometimes I didn't. Their tests are always done in a lab, rather than inside of a home. The results can vary depending on the user. What someone might find cumbersome another might find practical. In the past, I always went straight to their reviews on how well a vacuum performed on carpeting and bare floors. But, I would later be drawn to their emissions testings.
LackingVacuums You are 💯 right. They act as if a vacuum is good if it removes massive debris. They need to start doing carpet deep-clean tests, because removing surface debris is not deep cleaning the carpet. That’s what most Shark and Dyson owners don’t understand. I, myself, didn’t understand this until I bought the Kenmore 31140

Awesome totally love these tests
Very interesting..... looking forward to the carpet shredding test and whole house cleaning with weighed results.🙂

I still want 4000 RPM. 😂
Kenmore vacuums are very impressive this machine and the Kenmore Crossover Ultra are very impressive.
She cleaned the master bedroom yesterday with it and said that was enough. Too heavy.

Always remember...WITH GREAT POWER, COMES A GREAT AMOUNT OF NOISE!
Uh, this vacuum is very quiet compared to many other clean air machines.
Hey Bill will you please do a whole house cleaning video of The Kenmore Elite Vacuum Cleaner but can you please let Ellie do it?

Is this because the inducer motor on the Riccar is an actual direct air motor?

The two motors are the brushroll motor and the induction motor in the lower body.
Good job buddy

It has one suction motor and one brushroll motor as seen in the reassembly video.
That much lift is too much for area rugs. Its impossible to keep them down with suction lock. The lift is great for attached carpet.
Actually, my measurements prove about 20-30 inches is plenty. Airflow is something else entirely.

remember, I'm talking about performance numbers at the nozzle, not at the motor, which is much higher.
Cool
Great Video! I wonder if the 31140 Model, without the Motorized brushroll has a higher RPM?
I would hope so, but I don't have one to test.
Impressive airflow. Who manufactures these machines for Kenmore
Panasonic is one partner I believe
Yes but not anymore.

Interesting that the brushroll doesn't even use a belt or even a separate motor. It's just directly powered by the primary motor.
The motor is inside the brushroll itself.
Are you going to do a one pass deep clean test for this?
I'm doing two cycle tests for sand and fine dust these days.
Always listen to consumer reports

No 2speed brushroll?
Nope, just one slow speed.
VacLab that’s crazy. I used have purple one and had two speeds. I guess they cheapen out lol
@@nmvac82 what happened to it?
VacLab I give it away. It was bag less
