That Vorwerk Is Really Something Quite Special But I have a question: Does the G6 label really say 580 Watts? I've never touched a European 240 Volt Kirby and I'm surprised that it would be rated at less than 840 Watts. I would expect the motor coils to be different but I wouldn't expect the...

Do You Live In A Hospital? Since people don't normally live in Hospitals, that point is invalid. Also, hospitals use different methods of cleaning floors/hallways than residential homes. I also don't wear a hazmat suit although that might be the safest place to be at the moment. Completely...

RE: Jon in Reply #12 You NAILED it! Exactly right. If you need to pump water (fluid) and/or lift an item (bowling balls, etc.), high suction is required. If you need to move dirt in a volume in air, airflow is required. Keep the air moving and you keep the dirt contained in it moving. Bill

Let's Examine The Original Statements, Shall We... Mark's Claims (with no evidence of course). 1) Personally I prefer low pile carpet or hardwood floors as "they are more hygienic." Where is your evidence that hard floors/low pile (bare floors with fuzz) carpets are more hygienic? FACT...

E2 2-Speed Motors Never Wear Out? "The motor itself will never wear out as there are no carbon brushes." Tom, This motor has bearings which wear out/fail in a fairly predicable manner. Rainbow wants you to run these newer machines as much as possible and when the bearings go, have customers...

2nd Correction for Reply #4 I typed: Shop-Vac and other companies have insane false ratings like "6.5 Amps" I meant: Shop-Vac and other companies have insane false ratings like "6.5 HP" It was bad "unit swapping" day. I hate it when I have those. Bill

Correction for Reply #4 I typed: A Hoover Celebrity couldn't run at 3.7 HP because that would mean 3.7 A x 120 V = 2760 Watts, which would require a 23 Amp 120 Volt circuit. I meant: A Hoover Celebrity couldn't run at 3.7 HP because that would mean 3.7 HP x 746 W/HP = 2760 Watts, which would...

I See A Massive Suction Loss Which is by design. Still, what a shame to lose that much from the hose to the PN. From Hose To PN: 90-16=74" Loss From Wand To PN: 76-16=60" Loss Thomas Rectenwald's hot-rodded 12A Lux Marquise pulled 91 CFM paired with 38" of suction. It's a real bear to push on...

I Second The E2 1-Speed Recommendation In Mini Meet #19, I measured the highest Rainbow canister airflow ever from an E2 1-Speed (I have not measured the SRX's airflow yet). Results: 107 CFM filter in and 127 CFM filter out. The measurements start around the 21 minute mark. Newer E2...

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...
