I should also add that the brush roll light is a constant green and doesn’t flicker. | ||

@Tekjunkie28 I've been saying this for years. Despite popular belief on vacuum land, Kirby's are only mediocre in terms of power and performance.
I do really like Kirby Vacuums but they're they're definitely lacking in power compared to modern alternatives. Stepping said rainbows aren't the most powerful vacuum either but they're definitely not underpowered I talked about this in-depth in this video which upsets a lot of people. | ||

The last vacuum to go over the carpet will always pick up additional dirt than the previous vacuum because the agitation from the first vacuum raises the nap and combs the fibers up. Then when you go over it with the other vacuum, it has a clear air path down to the backing where it finds more dirt. Kirby salesmen love to exploit this when they demo vacuums in homes where they have you use your own vacuum first, and then they go over it with the Kirby and it "magically" picks up more dirt and then presto they get a sale. You could go over it with a Dirt Devil even and it would still pull more dirt out (not hating on Kirby - just stating what the sales tactic is).
The Rainbow E2 black is a water filled straight suction tank vacuum with a power nozzle, the Kirby is a full size HEPA upright. You cannot compare them as to who is better - it is apples to oranges. Contrary to belief, I do not think this is is a battle of Kirby owners vs. "the more money you waste the better it is" owners. What I think might be happening is it is just simply an issue with the carpeting and how it is made today. Carpeting has recently started being made with rubber backing for better flexibility and spill and germ resistance compared to your standard nylon weave backing. If your carpet backing is rubber this further exacerbates the problem because vacuums will grab right to the rubber and form a seal when they get close enough to it. Kirbys have a lot of suction, and if you give them the opportunity, a Kirby will eat a throw rug whole. The Rainbow's nozzle is a lot lighter than the Kirby and looks to be plastic, so it floats across the top and doesn't really weigh down the carpet much. The Kirby is heavy, and sinks itself into the carpet (you mentioned you had berber, it looks like a plush nap in the photos). When this happens, it creates a similar effect to the blowing into a bottle metaphor. The vacuum has suction, agitation, etc, but there is no airflow passing though the ultra thick carpeting around the nozzle for the vaccum's suction to lift it out and remove it. So the vacuum is sucking on the carpet with all its might, but nothing is being picked up and carried through into the bag. You can't raise it up any higher obviously as then you won't get deep into the carpet to agitate it. This explains why you are getting all the fine debris off the surface, but the heavier stuff is getting left behind that is deep in the carpet pile. Usually vacuums become harder to push when they start gripping into the carpet too much, but because the Kirby has power drive strong enough to push furniture out of the way to help motor it along, it usually will go unnoticed. When I was Googling this problem - I actually found a Vacuumland topic from 2013 of the same circumstances you described - Kirbys hard to push on berber carpet. www.vacuumland.org/cgi-bi... If you skip down to Post# 257931 on that link, there is a mention of changing the brushroll to a softer bristled brushroll for delicate carpets on the Sentria. Maybe that is what you need too? This all just my theory and I make no claims of it being correct, it's just my best guess on what's going on since you went over the entire Kirby and everything is all in order, and the Rainbow is also working properly, so there's not much left that could be the issue other than the carpeting. Good luck! PS: Here's a Consumer Reports report on vacuums and ultraplush carpeting.

Hmm
It's amazing. I love rainbow and I love Kirby's. I also have or had a rainbow black/platinum and a sentria. I sold rainbow and now have a silver. My sentria has a avalir nozzle.
I don't think a rainbow can out deep clean a Kirby. It's apples to oranges. Kirby deep cleans carpets well. I use the rainbow and it smells clean. I don't know about the dirt but the air is cleaner. The rainbow brush roll isn't as aggressive. You have a screamer royal, eureka/sanitairre or a central vac. Those are closest in CFM. The Kirby CFM is roughly 130-150.. rainbow is 95-120. There completely different machines I think there stop the bagged and bagless water filtration systems. I will note I've never owned or tested a miele, or sebo. I have read great things but this is from vacuums I've used. You can suck dirt mites etc out of a pillow with a Kirby but rainbow fluffs it up with clean HEPA filtrated air. Les | ||

Hmm
The consumer reports are mostly bogus.
Kirby probably is best carpet vacuum. Rainbow is better than siren and any other water base vacuum I use my wessell werk on rainbow and it gives Kirby a run for the money. I'm not buying a top performer from each. The Kirby would deep clean the carpet. Rainbow could be a better all around vacuum but it's not a better deep carpet cleaner. Les | ||

@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. | ||

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. Les | ||

@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. | ||
