Kirby Sentria 2 not outcleaning a rainbow e2 black

[ralph123]

Rainbow may make a better quality machine than Sirena, but the power nozzle designs have been flawed. I have not tested the latest Rainbow, so I cannot comment on that one. I do trust the carpet and rug institute tests. I’m not surprised that a Wesselwerks power nozzle would improve the performance of the amazing Rainbow. Canister vacuums are very versatile. I prefer a bypass upright even if it cannot perform as well as a Kirby. If rainbow has independent test results showing better performance than Kirby on carpeting then they should make them public.

Proof how good Kirby is


I can confirm that Kirby is the ultimate carpet cleaner.
This test shows it:

@mike811 I don't think anybody's saying that Kirby's performance is bad.
At least here in the USA with the hundred 110V units I can't say it's anything special.

I believe rainbow tout clean the Kirby based on both having good airflow and good water lift numbers. I have found over the years that machines that have both of these things clean very well better than a machine that has one or the other.

Hmm

Saying a rainbow could outperform a Kirby. It nor any other cannister is going to pull CFM the Kirby does. The Kirby bush nozzle vs any hose cfm.
Kirby is 130-150. The highest any hose I've seen was 118 CFM. My point is there is no rainbow made it any cannister that's going to pull near 130 CFM.
You can say " I feel this way". The airflow is a fact. The vacuum cleaning is an opinion. Your opinion is not a fact.
You can believe what you want and so can I.
You like apples I like oranges.
There's no need to upset probably the two most popular vacuums.
It's only ones opinion on which they prefer.
I think everyone can understand this post.

@lesinutah There's a lot more to cleaning than just CFM.

The overall nozzle design between the two is light years difference.
Again I'm not asking you to understand the physics or technicalities of it.
Just understand that new Kirby is not the undefeated carpet cleaner that's so many folks put it up a pedestal as.
There've been lots of threads on here and talk about machines that do out clean Kirby's I'll let you search that for yourself.

You don't seem like technical guy car guy.

but it's like people who only care about a car's horsepower rather than its weight ,handling and maneuverability.

I have both and think they both clean well. With that said, seeing the actual dirty water and carpet fuzz


seems very impressive even though I vacuum more than once a week. I do enjoy the fragrance that


you can put in the Rainbow. Pine is especially nice during the holidays, but you should only use


the genuine fragrances..... The later power nozzles with the side rotary brushes work very well.


 


I don't find it hard to clean. I pull the carpet fuzz out of the basin and put it in the trash can that


is in the bathroom, next to the sink. Then I flush the dirty water down the toilet and flush a few times


after. I have never had a problem.

What it comes to carpet cleaning performance the brushroll/cleaning head is the most important aspect. High airflow vacuums usually are great at fine dust pick up. Especially if the carpet is deeper pile. They don't need stiff brushroll. Suction is needed for long hoses to maintain the airflow. For heavy particle pick up you also need good suction.
Low airflow/high suction vacuums are the worst vacuums for optimal carpet cleaning.
Many cheap vacuums with low airflow and low suction try to compensate it by using extremely stiff brushroll. They can be pretty good at carpet performance, but the tradeoff is high carpet wear effect.
What I have tested and experimented even some of my old canister vacuums like Miele S234i is great at carpet cleaning if I use proper full size powerhead like Wessel Werk EBK 340 or Sebo ET-1.
Surprisingly some of these old canisters have high airflow and suction like the old Miele S234i. It's just slightly less powerful than my Miele C3 with a 1600 watt motor.
So far what I have tested my best carpet deep cleaner (sand) is my commercial Kärcher upright (Sebo BS36).

I know

My point was logic based. I just said Kirby creates the highest CFM. What do vacuums do. Vacuums move air. That Kirby has highest CFM means it moves the most air.
I never said it was a better vacuum.
I stated a fact.
One is a cannister vacuum with a 7' hose water based bagless. The other is a direct air bagged vacuum.
There two different systems completely. I never brought up my opinion as fact. I was pointing out opinions are not facts.
I'm not on here throwing around my opinions are facts. You can't compare the 2 vacuums and expect people to believe your opinion.
Everyone has an opinion.
If your reading into my post that's fine. I never stated one was a better vacuum. Other people on this thread are.

High airflow does have benefits:
