Dyson Radial Root Cyclone Doesn't Work Very Well!

[sptyks]

You guys don't get it...

The Dyson Ball design will always be plagued with problems. Mr. Dyson knows this. If the new Big Ball were perfect, then Mr. Dyson would have nowhere to go. He would have nothing to reinvent. That's why his marketing schemes are full of lies. His commercials state that the Cinetic has no filters and that the cyclones never clog. That's a lie. It has been proven that they are indeed capable of clogging.


 


I know that the bag in my Kirby will eventually fill up and need to be replaced approximately twice a year (it's a very large bag). No big deal. I just pull it out, drop it in the trash and pop in a new bag. Takes about 2 minutes twice a year. No filters to wash or replace or worry about. EVER!

 

[alexhoovers94]

Can you whip the hose and wand out on your Kirby to be ready for use in 2 seconds?
Does it operate quietly?
Does it have high filtration levels?
No, the answer to three simple questions that the modern consumer wants!

I wish Kirby would move forward and stop churning out the same old, same old.

 

[sptyks]

Not all true. I have a Heratige II Legend that is super quiet. Makes much less noise than any high pitched whiney bagless vacuum I've ever heard.


 


The bags are made of a high quality HEPA cloth material that filters down to 1 micron, as good or better than any bagless vacuum.


 


The Kirby"G" series is over 20 years old because it is such a good design. FACT: No one has come up with a design that cleans carpet any better than a "G" series Kirby. I have a Sentria and it is a beast when it comes down to cleaning carpet!

 

[alexhoovers94]

Nobody cares about carpet cleaning anymore, they just want a do it all quick vacuum, and a Kirby is not that.
The G series is old now, and they need to make something that people want to by, people who buy Kirby's are forced into buying them. Some people want them but most people don't want the hassle.
They want something quick, light and easy to use.

 

[dys0nb0y]

why does someone have to go in to threads that had nothing to do with kirby and make it about kirby and say load of crap about dyson i find it really pathetic.

Nobody cares about carpet cleaning any more

Well, most owners don't. That's the harsh reality. Infact well before bagless vacs came on the market and when cheaper brands used to exist outside the realm of Hoover, Electrolux etc, most owners failed to change the dust bag until it was too late.

Which is different for most collectors who would rather either used a prized modern day daily driver or something vintage, because we can!!

I dare say though that it won't be long until everyone who doesn't give a fig about a vacuum cleaner will go down the robotic route because, quite frankly in this day and age every home should really have a robotic vacuum cleaner by now. They're not all that expensive after all.

 

[sptyks]

But Nar, please excuse me. I have never seen a robotic vacuum except in Walmart on a shelf. So, how well do robotic cleaners clean plush carpets? How much suction do they have?

 

[sebo_fan]

Never seen a robotic disc on a shelf in Walmart? Oh my goodness. That surprises me given that you can get almost any kind of machine in the states.

I have no idea how robotic vacuums clean carpets in general BUT I have seen them in use in other homes. To my eyes they seem to leave carpets looking clean enough and do the job as designed.

As for air watts? We all know its a Dyson fad word. But to keep you entertained, here we go - info taken online.

For a cordless vacuum I would expect pretty low - lower than any mains corded dirty vacumm or clean air vacuum infact.

From what I read online some brands like Neato and Roomba robotic discs offer 30 Air watts. Miele's Scout RX offers 22 Air Watts.

The Bosch Athlet cordless stick vacuum released last year in Europe offers 40 Air watts.
The Vax Cordless Air offers 21 Air Watts (same as Hoover Air Cordless)
Dyson Hand Held DC35 60 Air Watts

Suction, Im sure you will agree is not the be all and end all.

Having had the Bosch Athlet for a short time, I was impressed with its power, but the pick up on the Vax Cordless Air is better as a cordless upright vacuum in my experience - based solely on its triple dust channel Windtunnel design. Suction through the hose is minimal, which is probably how its low air watts test was conducted.

Plus, lets face it - whilst robotic vacuums for the moment exist in cordless discs for the moment, it won't be that long that other designs may well start to come onto the market.

My point is, that we should be having lots of different robotic vacuums NOW.

When you consider that electric cars have been around since 1995/7, technology may well be moving fast in most things, but not everything.

 

[sebo_fan]

Also, look at the fact that we can now cook on induction hob as opposed to older radiant or ceramic or halogen, where induction is also claimed to be more energy efficient and faster.

 

[sptyks]

I HAVE seen the robotic cleaners at Walmart but never seen one in use except in a commercial on TV. 


 


Without seeing one in use and in person I find it hard to believe that it can remove ground- in dirt on a thick plush carpet where I believe you would need a powerful upright vacuum. I picture the Roomba or similar device to be useful for picking up dust and debris like cereal from hard floors and low pile glued down carpet found in commercial environments.

 

[alexhoovers94]

Even powerful uprights tend to leave things at the base of the pile of very thick carpets because dirt and grit always tends to stick there and doesn't want to budge, even with good agitation it doesn't work well on thick pile carpets, especially shag pile.

 

[sebo_fan]

Talking of commercial. There's also a few cordless discs by Karcher for the commercial market.

Can't be all that bad.

"FACT: No one has come up with a design that cleans carpet any better than a "G" series Kirby."

Stan....are you sure about that? Tell ya what, I can say this from personal experience comparing my 2 Royals to my Kirby G4 & Kirby G6....go ahead & take a new Kirby Sentria II or Kirby Avalir & put it up against a brand new Royal Metal. I guarantee you the Royal will clean WAY BETTER than the Kirby. If I was buying a new upright & was comparing Royal to Kirby, I would definitely buy the Royal over the Kirby.

Kirby may produce a good upright, & arguably one of the best cleaners on the market, but they have numerous improvements yet to make. They need to start putting a metal fan with more blades & deeper pitches that move more air, & they also need to adopt a brushroll with stiffeners like Royal has. And they also need to get rid of the second speed & go back to a single speed model, & put a suction vent on top of the powerhead for certain types of carpeting where some airflow needs to be released. Part of the reason why Royal moves so much more airflow isn't just the fan, but the fact it's constantly running on high speed for carpet cleaning, whereas Kirby G series always uses low speed, unless you "trick" the Kirby by using a small flat blade screwdriver to push the second rod in & activate high speed.

Why wpuld you want to use a great big clunker like a Kirby, so inconvenient!
There is no denying the are really good cleaners but they are a right faff to bother with.

 

[dys0nb0y]

when i had my kirby one of the thing i hated was a the smell it was disgusting.

 

[marcusprit]

Yeah faff faff faff Heavy bulky noisy not the best filtration despite what they say but they do clean well and they are very reliable though.

 

[kirbyg6]

I wish kirby would make something more interesting and less heavy to use

 

[marcusprit]

Yes I agree George it's about time they came out with something new and less heavy them I'd consider one.

 

[alexhoovers94]

Well, I agree, the design has been used since 1990, it is about time it is changed, it is a very tired out, outdated design.

Royal vs Kirby

Well Rob, re (Reply #221),


 


I used to own a Royal 2075 that I got in 1998 which I used for 14 years until I got a seller refurbished Kirby Sentria (made in 2009) off ebay in September 2012.  I was quite satisfied with the performance of the Royal 2075 until I got the Sentria. 


 


 I bought the Sentria because I was always curious about the Kirby vs Royal rivalry that I was reading about here on Vacuumland and wanted to compare them myself. I always took good care of my 2025 and replaced bags, belts and brushroll when needed.


 


 The first time I fired up the Sentria I turned on the Tech Drive and was amazed at how easy it was to push and pull across my plush medium pile carpet. It manuvered very well for a machine that was 8 lbs heavier than the 2025. After a few days of vacuuming with the Sentria, I decided to do a performanmce test of the 2 machines.


 


The Sentria was polished to a high brilliance and came with new cloth HEPA bag ,belt, and the new High Performance (extra stiff) brushroll already installed. The bag was less than 1/4 full, so I left it in place. The Royal had a brushroll and belt that I installed less than 6 months earlier. The bag was almost half full so I replaced it with a new bag. I also put on a new belt.


 


Now time to do the test. I have a light beige carpet so I decided to use coffee grounds for a good contrast. I got this idea from a post on Vacuumland. I took 1 cup of fresh coffe grounds and a spread them over a 4 foot by two foot section of my living room carpet.  I took another cup of coffee grounds and spread them over another 4 foot by 2 foot section of my living room carpet.  I fired up the Royal and ran it one time up and one time back.  I repeated this procedure with the Kirby on the other test section of my carpet.  I then got on my hands and knees and closely inspected both sections of the carpet.  Both machines did an excellent job but the Royal clearly left slightly more coffee grounds on that section of carpet.  So, IMHO, in this test, the Kirby Sentria won.


 


I tried the test of tricking the Sentria to being in high speed mode with the nozzle on.  I turned the Sentri on and lowered the nozzle to the height that I usually use to vacuum my carpet.  The suction was so great that I could hardly push the machine with the tech drive turned off.  With the Tech Drive turned on, It was almost the same effort needed  to push when the motor is at normal speed, but at high speed I could hear the gears straining with a very noticeable whining noise.


 


  I did some research and discovered that the two speed motor in the Kirby G series spins at 13,000 RPM at normal speed which provides about the same or even greater airflow than most other "direct air" vacuum cleaners on carpet.  At high speed the motor spins at about 16,800 RPM.  This is only used for that extra suction needed when using the hose. FYI there is a youtube video where the Baird Airflow Indicator was used on a Royal Everlast. When connected to the hose, and on a scale of 0 to 10, it reads around a 4 or 5 on the meter. I own a Baird meter and when I connect it to the hose of my Sentria it reads a 7.5. When connected directly to the fan opening, it reads a 10 which is basically pegging the meter.


 


If you care to know how the new Kirby Amodel fan was designed, check the link below. 


 


By the way, I now own 5 Kirbys and I gave my Royal 2075 to a friend who needed a good upright vacuum.


 


Sorry this post is so long.

One way to improve Royals is to use the newer Filtrete type bags just now available.Under Hoover "B" bag.Tried these in my Royal uprights that can use a B bag and there is an improvement over the older paper bags.Like Sptyks like the Kirby better.Both vacuums have basically the same design,fan first-both have their fan intakes close to the floor.Both have bell type nozzles.Now if Royal would make their fill tube even larger bore like the Kirbys-think we would have a "draw"BOTH machines work well for me.The Kirby is of course better with the hose and hand tools.But even better than that is a canister vacuum.Right now I use my NSS M1.It is kinda like a super Kirby with a hose-the NSS has a trap in the front so coins,screws,nails,nuts,bolts,pebbles don't go thru thru NSS fan.However I have seen the fan in the NSS eat couduit box slugs,cable staples, and such and bends them up.These would DESTROY the Kirby fan.The NSS fan is like 8" diameter and made of heavy cast aluminum-the blades are quarter in thick!And they are reinforced.The NSS has a 13A motor.They don't call it the "Pig" for nothing!
