You Said... "My explanation is you need suction to keep the airflow high through the resistance of the carpet." I've never disagreed with that and in fact, I've made several videos proving that. Some have used bagless cyclones to as proof and one even used hose length as proof. You may be...

Still Believing Last Vacuum Wins Comparos? Remember this video I made a few years ago? I can take ANY two vacuums and claim "last vacuum wins." Watch a cheap $30 Bissell beat a Kirby here: Obviously, a last vacuum wins test cannot give meaningful results. Here's how the Math works...

To Quote Your Previous Statement You said: "It's not high suction and low airflow and it's not high airflow and low suction. A balance of airflow and suction will give the best performance." Since you said neither high nor low AND neither low nor high, the only ratio left to consider would be...

Mark, That Would Be An Incorrect Assumption Equal airflow and suction at the PN is a disaster. I have a plethora of tests easily proving this. Once the airflow has arrived at the PN, the suction almost doesn't matter at all. For example take my Kirby DS80, sporting a whopping 125 CFM paired...

Part T2050H-6T is a Thyristor And is available for $1.67 from here: https://www.mouser.com/ProductDetail/STMicroelectronics/T2050H-6T?qs=cHcTzCDd3fpSyEC%252BQoKu2g%3D%3D It controls the speed of the motor. I'm unable to tell what the other part is on that board. If you can get clear pics, you...

Post# 420067 , Reply# 18 The S40P box is blank. Did you have a chance to view any of my "carpet reset" videos like the one posted above? In order to have valid results, the tester must FULLY reset the carpet to a extraordinarily clean level. Since you are unable to FULLY clean your installed...

HP Ratings Are Also Mostly False If anyone claims more than 2 HP (for US machines, unless they specify a dedicated circuit is required). 1 HP = 746 Watts 2 HP = 1492 Watts Standard 15 Amp circuit @ 120 Volts = 1875 Watts You said you saw 70's canister vacs that were rated at 1/4 or 1/2 HP...

I Misread Some Of Your Data And realized that the chart you posted was "blank" next to the S40P box (was reading posts on my phone around lunchtime). Have you properly "reset" your test carpet to make absolutely sure there was no remaining sand (flip it over and vacuum underneath)? One very...

Devin That's Quite An Improvement Over Your previous S40P test where you got 83.23 CFM with two motors. So now we have a $1000+ dual motor rig that can properly challenge a Hoover Tempo Widepath. 91 CFM, 42" of nozzle lift, and about 80" of hose suction. My sand tests were similar to yours as...

Devin & Mike Thank you both for posting your tests. I was wondering how many posts would build up until previous tests would make an appearance. Bill

After Testing And Logging Numbers For A Few Years... I have some general answers. As usual, your mileage may vary but assuming fairly typical scenarios, here we go: For non-power assisted uprights with average size nozzles (say 12" x 2") 90 CFM paired with 30"-40" of suction For non-power...

Bissell Powerforce Compact Tests I've done extensive testing on a 2013 model, which is older than what is pictured above. Bottom line: incredible on my medium pile carpet. It easily bests vacuums at 10 times its price. I nabbed it used at a thrift store a few years ago. It needed a belt and the...

Kevin, I Performed Some Tests A While Back And hopefully, these videos will answer your original questions about Rainbow filters. Reconditioning A Smelly Moldy Rainbow HEPA Exhaust Filter Rainbow E2 HEPA Filter Tests Old Versus New Closed Room Air Cleaner Test Using A Rainbow E2 Platinum...

Great replies everyone Kenny, thanks for your support. Tom, I figured you would have some great historical knowledge of who had what when, so thanks for all your "corrective" info. I just love rooting out lies and deceptions. Keith, there is a local ReStore very near me but to date, I've...

Or at least this Aerus store in Grove City makes these claims. How many of these are true? All of them, some of them?

Here's The Sanitaire Wide Track II

I Was Unable To Measure This Monster But I'll Guess Over 40 lbs.

The Early G Series Kirbys Weigh Quite A Bit And this one tips the scale at 23 lbs. including the cord.

This oddball LG Vacuum Looks Fairly Heavy And it weighs 22 lbs.

I Tend To Agree With The Winning Formula Comment From Alan, at least performance-wise. I might make a video more fully explaining this, but it may very well be that the "Tech Drive" is the most important piece of engineering in modern Kirbys. Think about this: With the Tech Drive, a HUGE...
