Is the Kirby's airflow and performance over exaggerated? |

Bill placed his Kirby on a flow through carpet on top of his airflow box and the CFM dropped by 65%.
Now place the Kirby on a sealed carpet where the resistance is much higher what will the result be then? Obviously when the resistance is much higher the flow will be much lower (simple physics right) It wouldn't surprise me if the Kirby's airflow dropped by 90%. So for the Avalir from 150cfm to a whopping 15cfm. Doesn't sound as impressive on a sealed carpet. | ||

A lot of vacuums struggle on rubber backed ultra thick carpet, not just Kirby. The more suction a vacuum has the stronger the effect will be felt.
I'd rather have carpet that can be cleaned and not suffocate the subfloor than to have ultra thick pile carpet that will trap fleas and mites and all kinds of other nasties. If they start making rubber backed plush carpet that has a breathable membrane that lets airflow through it - this will help a great deal. | ||

Personally I prefer low pile carpet or hardwood floors as they are more hygienic.
The Kirby will suffer more on sealed carpets because of the low suction. In my opinion a Kirby will have a very similar performance on a sealed carpet to the best clean air motor Vacs. This post was last edited 03/13/2020 at 04:15 | ||

Well here we go again😂
Like you know I have rubber backed medium pile rug and Kirby did amazing job removing sand from it in my sand in the carpet test. So even with the low suction it cleans very well. Note that Kirby needs that airflow because the cleaning head opening is huge. My G6 has stiff oblique brushroll. My Dyson DC40 MKII did pretty poor job in the same test. And yes rubber backed rug/carpet is challenging for most of my vacs. | ||

Fine powder is fine for the Kirby unless there is unrealistic amount of it. Then the belt starts to slip. In the normal situations Kirby is very good at fine stuff. Now where this whole Kirby thing even came along? I don't even use Kirby so often. Actually very rarely just to enjoy it like classic american car 😎 (my friend has 1966 Chevy Impala 😍) But most US homes have wall to wall carpeting and soft high pile carpets are now trend. On those Kirby is hard to beat. What I use for daily vacuuming: Canisters with the Sebo ET1 powerhead. | ||

I know that Mike you prefer to use a canister cleaner. I just need some convincing of the Kirby's performance on a sealed carpet. I'm not convinced it will perform any better than clean air machines on this surface.
On porous carpet then yes it will probably pick up more dirt than most other vacs as there is much less resistance through the carpet. This is just a discussion not looking to start a war 😊 | ||

In the US, most of our carpeting for the past ten years (or even longer) have had a plastic-like coating on the underside to prevent water from our "steam cleaners" (hoover and bissell, etc.) from wetting the pad and creating mold.
I wondered about how that would affect airflow on a vacuum, so I made a little test (not scientific but enough for me). I took the bag out of a Hoover Concept, a Kirby G5, a Hoover Convertible, and a Eureka ESP. I adjusted the machines to where they "pick up the carpet" meaning they had formed a seal. I felt the air flowing out the exhaust pipe both before and after adjustment. I just used my hand. While they all had different amounts of airflow before they were properly adjusted, afterwards they all had about the same amount. These are all 'dirty air' cleaners, which are best for carpet cleaning. The only real difference I found was the tightness of the seal to the carpet. The Kirby had the tightest seal followed by the ESP. The Convertible had the least amount of 'seal' but still have about the same amount of airflow after adjustment that the Kirby had. My conclusion was that all these fine cleaners had about the same amount of air movement in normal use (with clean bags) and I feel they would remove about the same amount of dirt. 2 cents, for what it's worth. | ||

Direct air vacuums are the best for wall to wall carpet especially the newer Kirbys and Eurekas with 7amp motors (Eureka). The virbagroomer beats carpet like no other extracting sand, grit, etc. The Hoover Concepts also do an excellent job! I enjoy my canisters and really bypass uprights are just canisters if you think about it. However, I do not feel a canister cleans carpet as well as an upright. Canisters are also less energy efficient because they draw more amps than a traditional upright.

It's a "discussion" that you have tried to start on other threads. I am convinced that your intent was to disturb the peace. We get it. You have a thing against Kirby. Repeatedly posting about how much you hate a specific brand is a great way to get a one way ticket to Banville. I've started to grow tired of all of the arguments on here recently. It's a major buzzkill and makes me not want to use this site.

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: deeper pile carpets literally absorb dust/dander/fluids because they act like a sponge, effectively wicking away the aforementioned stuff. Think of a baby diaper. More absorption is better. From a physical standpoint when a person walks/shuffles around on low pile carpet and especially bare floors, dust and debris gets “liberated” back into the air (or stuck on socks/shoes). When I rub sand and baking soda into my medium pile carpet, it literally disappears and no one would ever know it was there, effectively removing it from having most negative health effects. Here's a link to a brand new study: carpet-rug.org/study-shows-carpe... 2) The Kirby will suffer more on sealed carpets because of the low suction. Low suction compared to what? Newer Kirbys have around 30" of nozzle suction paired with insane airflow. They do not have 100" or more of nozzle suction paired with low airflow like most stick vacs. Based on extensive testing of clean air bagged machines, the best I've come across is a little more than 40" of nozzle suction, which isn't that far off and is paired with much lower nozzle CFM, like 80-90 CFM. The best full size Dyson I've tested pulled over 60" paired with less than 60 CFM. REMEMBER: SUCTION DOES NOT MOVE THE DIRT, AIRFLOW DOES. Suction is a pressure and does not carry dirt through a hose. 3) In my opinion a Kirby will have a very similar performance on a sealed carpet to the best clean air motor Vacs. Although I do not test specifically on low pile sealed carpet, I have done plenty of testing on bare floors back in 2017 and Kirbys did extremely well with a variety of dust, sand and debris. Keep “opinions” out of the argument and stick with actual testing. Bill | ||

I have: hardwood, ceramic tile, and wool carpeting
I used a Kirby in a church, when I worked there. It was very strong. The carpet was commercial, as well.
Hoovers are all that's used here in my place. The wool Chinese rugs still 'shed'. The rest is Karastan.. sheds, too. Kirby cleaners were never used in my house, but, I know how strong they can be. But, all of my Hoovers (with genuine Hoover bags) do a fine job here in this old place. Good luck. let's be peaceful. The world is nasty enough without us helping. | ||

@vacfan1982
Well I definitely think you're right on here people definitely exaggerated how well Kirby's clean. I've always found him to be just average (slightly below-average in 2020) in terms of cleaning ability. In order for a vacuum to clean really well it must have high airflow and water lift. Then all that must be put into well engineer design. One of the problems with the Kirby is the nozzle design is square and quite outdated. I made the argument years ago in a video that a Kirby doesn't really clean any better than most straight suction vacuum cleaners these days. This is an unpopular opinion on vacuum land but these are the facts the way I have seen it over the years and used literally thousands of different vacuums. All that being said a Kirby belongs in every vacuum cleaners collection. CLICK HERE TO GO TO vacuumdevil's LINK | ||

When you agitate carpet it has been shown that the fine dust and allergens can become airborne also dust mites the major cause of indoors allergies are easily removed from hardfloors but they cling to carpet fibres.
And clearly hospitals will choose the most hygienic flooring and that isn't carpet. Speak to any allergy consultant and they will tell you to remove carpeting. | ||

Alex, You Perform No Quantified Testing And Promote
False testing methodologies like "working water lift". You have no scientific/repeatable results that I know of. I debunked working water lift in thread a while back. No one uses it except you and it doesn't prove anything at all. A Kirby DS80 cleans fine dust very well with pathetically low levels of suction.
Mark, The reason hospitals don't use carpet is a practical one. Cleanup. Imagine what a pain it would be to scrub out urine, feces, vomit and blood. It is much more expedient to simply wipe/mop/water extract it. So it's obvious no-one has read the recently released article I posted, so I'll post a snippet here: carpet-rug.org/study-shows-carpe... ========================= In Phase One of the studies, several types of new carpet, as well as new hardwood floor samples, were uniformly soiled with dust and allergens. Researchers found that, even before the carpet was cleaned, the levels of allergens, including cat and dust mite allergens, were lower in the air over all of the carpets than over the hardwood flooring, even after both flooring types were repeatedly disturbed by activities such as walking or bouncing a ball. ========================= Again, the ignorance on this thread is astounding, especially from people who perform no appreciable scientific testing. I've said all I have to say on the matter and everyone is certainly entitled to whatever fantasy they prefer, especially when it involves no rigorous testing and data analysis. Bill | ||

I repeat dust mites are easily removed from hardfloors but they cling to carpets. I suffer with dust mite allergies I went to see one of the best allergy consultants in the UK and he told me to remove the carpets and fit hardwood flooring. So I disagree.
Bill are you familiar with ohm's law? The higher the voltage more current will flow through a given resistance. In a vacuum cleaner the voltage can be seen as the suction, the current as the airflow and the carpet is the resistance.So low suction (voltage) will mean a low airflow (current) through a given resistance ie the carpet. Proven by science PS Hope you liked my email that's assuming your address is correct on here 😊 | ||

Mark, I Can See You Aren't Familiar With Ohm's Law
You said:
In a vacuum cleaner the voltage can be seen as the suction, the current as the airflow and the carpet is the resistance.So low suction (voltage) will mean a low airflow (current) through a given resistance ie the carpet. Proven by science. ========================== E=IR and P=IE Airflow would be liked to voltage and suction (water lift) would be likened to current. So many people get this one backwards. As resistance increases (carpet), current increases or more accurately ATTEMPTS to increase. If the current (suction) cannot maintain the voltage, the voltage (CFM) begins to drop under an increasing load (resistance). Voltage is a potential difference between two points, say earth ground and something else. The strength of the voltage (ability to resist a load) is current. The strength of the airflow is suction, which is the ability to maintain CFM under a resistance (carpet). Don't confuse the above with what the electrical motor is experiencing as that is a different ball of wax. Look behind the Kirby Avalir and Diamond Edition in my videos. See that giant blob of electrical testing gear? Do you know how long I've been designing/building electrical circuits and power supplies to feed those circuits? Try over 40 years. I'm also FCC certified so I know how to design/build transmitters and antennas. | ||

@vaclab You're really wanted to speak about scientific testing
With your cardboard box. I haven't seen you debunk anything, perhaps because your only platform is here? Not sure how or why you would want to go against an industry standard? You're in no place to debunk anything from your past comments and videos. Just accept that you are a form of entertainment and nothing more . I see you tried to bully people on here. You should just stop and agree to disagree New balance man. | ||

"dust mites are easily removed from hardfloors but they cling to carpets. I suffer with dust mite allergies I went to see one of the best allergy consultants in the UK and he told me to remove the carpets and fit hardwood flooring. "
okay then why are you here starting arguments about kirby? are you doing it out of spite because you cannot own anything beyond a stick vacuum or something? since you can only have tile or hardwood flooring in your house, that has absolutely nothing to do with kirby or their cleaning ability - you just want to start trouble which will subsequently get you banned. this post should have been a single comment on one of his videos, and not a forum post here. if you don't like kirby then so what? nobody has a gun to your head forcing you to buy it. if you actually try different vacuums and find out which one works best for you, and not just parroting what youtube influencers tell you to buy - this whole problem can be averted. vacuums are all built for different price points, different carpet and flooring types, and different uses in mind. you have to analyze their features, and see which one would suit you, try it out, if it doesn't work out for you, clean it up and return it. I have a wool area rug from 2007 and I found the best vacuum to use on it that doesn't eat the fibers and beats the dirt out of the pile is a 1920's Hoover. It has soft horsehair fibers that gently groom it and a obligue beater bar pattern. No surprise, because those were the kinds of rugs that existed in that time period just as well as oriental rugs. Mostly all nylon-bristled vacuums will singe wool rugs due to friction burn and the aggressive stiffness of the bristles. Just the same, you would not want to use a big powerful industrial vacuum meant for hotels and casinos in your own home, as they are made for low pile carpeting and are very very powerful and could rip a domestic carpet to shreds instantly. Here's a little $70 Eureka Powerspeed pulling a (literally) ton of sand out of a plush hotel carpet. It has the advantage because the brushroll creates static electricity which helps grab the sand out of the carpeting, and it has a big bin that lets more airflow intake in and out of the vacuum for better suction performance. that would be a plus for buying this vacuum, if you live near a beach or have a lot of sand issues. now here's a little fun fact - dust mites do not only live in carpeting. they live in every sort of fabric in your house. bed, pillows, curtains, the clothes in your closet, upholstery, etc. If you had a good quality central HVAC system with a hepa filter and also a good negative air particulate filter on it (most places in the UK do not own one because the houses are too old and small to even fit one in) and keep your curtains, bed, and clothes washed weekly with a allergenic detergent then dust mites would not be a problem. they cannot thrive in humidity levels below 50% either. it's a lot easier for a doctor to say "tear out the carpet" then to actually do any sort of testing on your home to find the allergy triggers. Doctors are not scientists and neither are vacuum shop mechanics. bill definitely has the upper hand here because he knows the science proven behind his methods through his life experiences and/or job, and that's the same stuff taught in electrical engineering courses, so the knowledge is sound and proven, and he is generous enough to share it with us. (even though all that math goes way over my head lol) | ||

Husky Vacs I have an MD Central Vac, Vorwerk VK150 , Miele S5, C3, Sebo Felix Sebo X4, Henry, Dyson V8. You can get anti allergy covers for bedding. I have a leather sofa so dust mites don't live there. They don't actually live in curtains but their faeces can do if dust mites aren't removed from your home, which they have been from mine. I also have a Blueair air purifier.
And no i'm not the biggest fan of the kirby having owned 2 of them but like you say "So what. 😃 there are things I appreciate about them though. But unlike Bill and some others I don't think they are the best thing since sliced bread and constantly bleat on about their so called superiority Baaaaaaaa 🐑 It wasn't my intention to cause an argument I was trying to get to the truth about the kirbys performance on a sealed carpet, I have been entitely civil and not personal like some.

Bill Current increases as resistance increases?
This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r. In other words, if we increase the voltage, then the current will increase. But, if we increase the resistance, then the current will decrease. When you placed the Kirby on top of a flow through carpet on top of your airflow box the CFM dropped by 65%, if you placed it on a sealed carpet where the resistance is greater it will drop even further. I think you know this to be true 😊 This post was last edited 03/14/2020 at 02:06 | ||

Again, the Kirby has a gold CRI seal, while Dyson has none. The Carpet And Rug Institute tests vacuums on all sorts of carpet types, including rubber backed carpet. I have used my Kirby on my rubber backed rugs, and it does an excellent job. It gets stuff that my Shark misses.
On a separate note, the moderator needs to lock this thread. This thread was intended to be inflammatory, and nothing constructive has been said as a result. I don't understand why people can't simply ignore a person who is trying to start drama. Just be nice! This is the last time that I am going to reply to this thread, because I think this whole argument is stupid and I have better things to do. | ||

Here Are Some Real World Figures
Since we never have "unlimited" current to prop up the voltage under an increasing load, the voltage will drop. Said another way, since we never have unlimited suction, the CFM will drop under an increasing load. Take a real long look at this actual motor performance chart.
At a 2" opening (low resistance), the CFM=141.5 and the suction=7.4" At a 1" opening (medium resistance), the CFM=95.3 and the suction=56.9" At a 0.5" opening (high resistance), the CFM=33.3 and the suction=112.7" Same goes for current limited electrical circuits. When the resistance increases, the current increases to attempt to prop up the voltage as long as it can until it maxes out and then voltage drops. You can witness a part of this behavior in countless videos I've made where I show the voltage drop under a 10A or 12A vacuum load (low resistance). And don't forget that the absolute value of what CFM remains is always the key. If machine "X" loses 100 CFM and only has 50 CFM remaining, that is still quite better than a machine that loses 25 CFM and only has 25 CFM remaining. So yes, I'm saying that a variety of dirty air machines, including Sanitaire, Royal, Kirby, classic Hoovers, etc., will have superior airflow on sealed carpets compared to low CFM bagless machines. They will not drop to something ridiculous like 10 CFM. Know how to tell? Because the vacuum would absolutely howl in protest and the motor would overheat in just a few minutes. Have a listen to what happens when a Kirby dirt pad gets clogged and airflow drops. A properly height adjusted direct air machine won't sound like this. I just cleaned a 6000+ sq. ft. church low pile sealed commercial carpet with a Sanitaire Wide Track II and it has a boatload of usable CFM when adjusted properly. Bill

May I ask why these post are being marked as offensive? I realized there are differences of opinion when it comes to technical data and personal experiences. I don't see any profanity, nudity or other things that I would consider truly offensive in this thread. I do hate continual brand bashing and I see it on both sites and many facebook groups as well but it's a fine line into censorship to squelch speech based on opinions.

Thank you like I said I kept things very civil. I wanted a discussion not a fight. I'm not bashing the Kirby I've owned 2 of them. I know their good points but I also know their bad points. But no cleaner is perfect.
I know it does a good job on porous carpet but the point of this thread was to find out how it performs on a sealed carpet. This post was last edited 03/15/2020 at 14:08 | ||

The reason this thread is being reported is because vacfan1982 is putrposely instigating arguments and causing a fight in general by purposely calling out users of the site and trying to prove his ego, like certain other vacuum shop backroom lackeys posting here and trying to get people on his side to be anti-Kirby and bash anything that doesn't cost under $700 and is premium brand plastic garbage with no parts after 1 year.
Like I said earlier - the first post he made should have been a comment on Bill's YouTube video - not Vacuumland. But he purposely posted it here because he knew it would start a big fight and he is trying to get users to side with him to prove his ego is right. He knows what he is doing and that is why he has been reported. | ||

Oh stop blowing it up out of all proportion it's a discussion about a vacuum cleaner! 🙄
Haha bashing everything that doesn't cost under $700 what are you talking about? I own premium vacuums 😂 If you read my profile you will see the vacuums I own. I don't have a big ego when im wrong I hold my hands up unlike some on here. You're making a lot of assumptions about someone you don't know and have never met aren't you Seems to me that it's you who is looking to start a fight This post was last edited 03/15/2020 at 15:49 | ||

I don't get why Kirby gets so much hate from some persons. I have not seen ANYONE praising Kirby to be the best carpet cleaner. Yes it's very good, but come on. Some limit to these trolls. Note that the airflow effects to every vacuuming job. Low airflow vacuums needs to be very near to the dirt to pick it up when the high airflow vacuum picks up the dirt from much further away. This is what I always experience in my day to day vacuuming. With low airflow vacuum I have to see much more effort to pick up the dirt. With low airflow vacuum there is much more effort involved because you have to be very near the dirt to pick it up. This clip shows it all: | ||

 A Kirby doesn't just clean by air flow. They keep improving there brush rolls. The airflow and the brush roll together deep clean. Also it is important to change the belt, before it starts slipping. They make a very stiff brush roll, which I am using now.. and it grooms my carpet better than there softer brush rolls. I have plush carpet. If you have berber carpet, you would not use this stiff brush roll.

4 those who say kirbys dont clean well at all probably have poorly maintained or very well worn-out kirbys or kirbys with aftermarket bags
i have classic III with original bag & aftermarket outer bag that accepts a eureka f&g bag with the aftermarket bag the kirby height selector needs to be lowered 3 notches for good cleaning resultd when the original bga installed the 2nd highest setting give best results (shag carpet gets pulled up close to nozzle) | ||
