I Also Confirm a Baird "2" With The Nozzle Removed So a DC65 gets a "whopping" 2 with the nozzle removed, which translates to 62 CFM. Why people spend well over $600 for this machine is beyond me. Bill

First off, thanks to Devin for providing the two actual measured readings. He works in a store that actually sells Miele products. By The Numbers: 141 Motor CFM: This is provided by the manufacturer and reflects the maximum motor airflow when not installed into the machine body. 111 CFM at the...

No, The MOST Important Feature Must Be The power switch light. There simply is no other easy way to tell if your vacuum is running. :) :) :) Bill

Adin, Got a DC14 for free as the brush roll was clogged with hair and the machine was making a funny noise. Got a DC25 for free as the owner couldn't be bothered to empty the dust bin and clean the brush roll. A trash find at the curb. Got a DC65 as the owner couldn't be bothered to empty the...

My Flour Under The Carpet Tests Reveal That... Deep cleaning below the medium pile carpet backing requires minimum nozzle CFM of: 80 CFM for entry level results, 100 CFM for good results and, 120 CFM for nearly perfect results, if the user wants to get very fine deep down dirt (dust) in no...

Adin, I didn't waste a single penny on this machine. It was a curb find on trash day in front of a $250K home. They replaced their DC65 with....wait for it...a Shark Rotator. It appears to be a case of "never loses suction" also means "never have to empty it and/or clean the cyclones". A full...

The first two measurements were easy to get, the last one (CFM at the nozzle) required me to build an airflow box. I think this pic should easily illustrate where and by how much CFM is lost in this machine. I think this is typical performance from a cyclonic bag less cleaner. From the base of...

Yup, That'll Do It Alrighty... Leaving behind blobs of sealant will create minute holes for dust to escape. Glad you were able to get your Sentria II all fixed up though. Bill

Stan, Anytime! Love to share methodologies... Bill

Stan, Yes, and here's how the testing procedure went. Example: 1) obtain a vacuum source that creates, say an "8" on the Baird meter. 2) remove said Baird meter and attach my GM8901 digital anemometer and take reading. 3) repeat the above two steps at least three times to obtain reliable...

EXCELLENT WORK DEVIN! A 7.5 is just about dead on 101 CFM from a straight hose. For your wand measurement, I'm assuming that you have the wands extended about three feet. A 6.5 is an equivalent to 95 CFM. Based on typical airflow losses from wand connections and the power nozzle u-joint, a C3...

Stan, Of course the Baird meter measures airflow, it just assigns it to a simple set of numbers. You need the "key" to unlock what an "8" means. Here's the key. Bill

Matt, Did you actually see dust building up somewhere on the front cover? I only ask because to date, I've redone 5 Kirbys (Heritage II Legend, G4, G5, G6, Sentria II) and have had zero dust leakage. Not even a dust film build up. But, I always completely, painstakingly, remove all the...

They Won't Because That Would Make Life Too Easy For the buying public. Imagine being able to comparison shop merely by looking at the hose or nozzle CFM. You might see a $70 Hoover Tempo with 106 at the hose and 80 at the nozzle and a $700-$1200 Miele, Riccar, Sebo, etc. with the same specs...

If Those Amazon Numbers Are True... than that would be absolutely shocking! Think about it: a well respected, high priced canister that has no better airflow at the hose than this 1980 Electrolux (new hose). So what people are buying when purchasing a Miele is exhaust filtration at an...

Mark, Please, please, please post the link and/or text in which you found 94 CFM and the hose end! If this is true, and I'm most definitely saying that it may not be, that would mean super colossal airflow losses in a nearly $1000 canister. As a reference, my 1980 Lux with a new vinyl hose does...

Using This Ametek Lamb Motor in a Miele C3... Would probably be overkill, but I wanted to find something that had as close to 141 CFM as possible to prove a point. No matter what CFM the motor starts with, you must take into account the hose diameter that will feed your power nozzle. Please...

Partial Reply #4 And by the way, my opinion comes from REAL LIFE EXPERIENCE. My Mom, when she was alive, had her own cleaning business for over 37 years, & we both cleaned many commercial & residential properties together, & we used pretty much everything available for residential & commercial...

Partial Reply #3 ============================================================================= So let’s see, your claim of 60%-70% airflow loss is totally bogus when using HEPA cloth bags. I do not use nor recommend paper bags of any type and even my U4007 Convertible has a Hoover Q HEPA bag...

Partial Reply #2 Furthermore, the Hoover Tempo ... So, Bill, your statement ... *See Rob's Original Text Above * =============================================================================== You’re in luck! I have done such tests! I will publish them here I believe for the first time...
