My E series arrived! It was bought off ebay for about $510 that's including shipping.
It was apparently a store demo model which has been lightly used.
I've only had a little time to play with it but it so far it's pretty cool not a whole lot of airflow to it but the powerhead seems to be a very good cleaner.

Not a whole lot of airflow?? Surprising statement as I thought it had a new motor. I wonder how that affects it's water pick-up ability?

Well when my baird meter is attached it pulls about a .75 which i'm shocked by in a rotho video demo they showed it reading a 4.5 they may have run it empty that may effect it's rating.

As for the nozzle it's the older style center belt model

New (Sort of) Rainbow

Sure does not sound right. Do you think you have a hose or seal leaking?
Do the fans look clean or maybe it has been used with something that has clogged the hepa filter such as demo products in the vac store?
Maybe something has been done to cause it have less air flow if it was used in a vac store, as a new Rainbow would not be sold in a vac store.

Something not correct if you don't have a lot of air flow with a Rainbow. I might understand it not having as much suction as some other machines but not the air flow. Keep us posted when you get the problem resolved.

I was having a new Miele demonstrated and it had very little suction because when the store owner checked, the machine had a PACKED bag. When he replaced the bag ,the machine was fine.

I bet someone on this forum would know what it SHOULD be pulling. You might send Ken Bashford a email and see what it should be pulling. He is who I bought mine from and has been very helpful. Tom Gasko would also be a good source of information about the Rainbow.
Sure makes you wonder what has been done or picked up by the machine. This would make me wonder if damage was done by the original owner and traded in or it happened when it was in the vac store.
I just changed my hepa filter for the first time after 2 years and mine was as white as the new one and I use my Rainbow to clean the garage floor, screened porch, aquamate and Rainbowjet. Mine has not been babied in any way but I do change the water often.

U must change the water often & never pick up "non-wettable" dirt like SheetRock (plasterboard) dust, Love My Carpet (carpet fresh powder) & fireplace ash. Don't vacuum too long with just one filling of water; once the water gets too thick, its time to change the water. U must never store the power unit on top of water basin.

New (sort of) Rainbow

Devin,
I wrote someone who has vast experience with Rexair and Rainbows and here what information I got back:
(1) Rainbow has used same brush less Hurricane motor for the last 8 years
(2) All Rainbows in that time frame should have 95 inches of water lift
and 290 air watts (air flow plus suction)

The only causes of less would be:
(1) abuse by original owner (not changing water)
(2) dirty separator
(3) dirty heap filter
He told me a LOT depends on how well the original owner took care of the machine.
The Hurricane motor has NO MOTOR BRUSHS, NO COMMUTATOR to wear out
(4) should have very high air flow and continuous air flow unless abused by original owner.

I hope you can find the problem with your machine. If you have any more questions email me and I will give you the person who has a LOT more experience and knowledge than me.

Thank you for your post Rob it is quite informative.
The hepa filter i've emailed Ken Bashford about to get that replaced. I have tried rinsing it out but whatever is on there is there to stay.
The seperator i've cleaned.

Though knowing it's suction and airwatts is great and working backwards using the formula of (airflow x suction) /8.5 = airwatts The Airflow should be about 25cfm

So with the Hepa filter removed it is performing at about that level it was pulling about 8 cfm with the clogged filter.

Devin,
I found the information I had written down on the E2 black Rainbow:

E2 Black= 110cfm
95 water lift
with increase in air flow on the carpet due to new power nozzle design.

Here is some of the figures I had for the older Rainbows:


model B=43 cfm
50 water lift

chrome D=60 cfm
65 water lift
D3 =50 cfm (added motor shroud)
65 water lift
D4 =65 cfm (added 9 blade fan)
60 water lift
E series=75 cfm
70 water lift
E2+Black=110 cfm
95 water lift

huh?

blackheart's profile picture
Many manufacturers when they take a cfm reading will measure at the motor to give it a higher number Take for example the Miele you will see a 140 cfm rating for them which is a motor rating but at the end of the hose you end up with about 55.

Dyson also gives higher ratings for it's vacuums than they can accomplish i will use the DC-11 canister since i have one. Looking at their spec sheet i can see a rating of 220 airwatts and 55 cfm with those numbers it would only have 34 inches of waterlift which places in it kirby territory. But my meter reads in at a 2 with it so using the figure of 20 cfm it would have 94" inches of waterlift.

The baird meter is really more of a comparison tool however it seems that each number represents about 10 cfm. it's not completely accurate but it gives me an idea of what the machine is pulling.

If the rainbow were pulling 110 cfm, It would have 1229 airwatts (110 x 95)/8.5= 1229, it would also read 10 on the baird meter.
With the airwatt and suction rating the formula says 25 cfm the meter is reading at a 2.5 telling me it is pulling around 25 cfm at the end of that hose.

FYI: The airwatts calculation isn't so simple. You can't use the sealed suction in the calculation, particularly since the sealed suction occurs with 0 air flow. Per Ristenblatt's web site your estimate will be about 4 times too large is you use sealed suction.

Since I'm selling these things as a side job (well more a the fact that I owned two and they wanted me to do it and it fit my schedule). I am not going to lie to anyone or pitch them one bit.

I have played around with them quite a bit if the airflow is poor, it seems way off, but a replacement filter seems like a good plan of action if the seperator is clean. Sounds like it has less airflow than my one speed E Series?

A trick for non wettables? Add a drop of dish soap to the bin. Remember the seperator will keep the water out of the motor, that is what it was designed for. It imakes a foamy mess but works. You can drop these things sideways and as long as they're running water is not getting into that motor. The foam from the soap traps the non wettables.

I still wouldn't recommend it for that purpose.

As far as storing on water basin? That solely depends on how well you dry the water basin. It is their precaution, but if you dump and thoroughly try the basin your fine.

Take it from my perspective, I have maybe 20-30 Fantoms, 2 Dysons, 4 Kirbys in the garage, 2 Rainbows, and various other machines. The Rainbow will do a fantastic job and last forever if you care for it. My single speed E series HEPA filter is still perfectly white, and that is after vacuuming disgusting black crap my Dyson DC33 left behind. Dyson is not perfect in this respect because the internal filters still need cleaning (which leads to loss of suction regardless of their claims), and I don't feel their brushrollers are agressive enough..

Is it the most convenient? No. However after the dust cloud of emptying the Dyson you begin to understand what they do what they do and why the machine is still around after all these years. The more you use it the less inconvenient it seems. Their current powerhead is very nice for a cansiter.

Is it expensive? No doubt.

If you have the time to use it properly it will perform as advertised. If you maintain it it will last a long time. To any buyer, be it on ebay, craigslist or a dealer, it you take care of it it isn't a 6 month machine like your $50 disposable, but you have to decide if you like it because it probably will last 20+ years.

The other positive is it holds value well. Rainbow gives you a good trade in value. They sell at commendable prices online (unless someone uninformed unloads it cheap). It is a fairly safe buy in that respect.

Dish soap???

mark40511's profile picture
NOOOOOOOO!!

You don't want FOAM in the basin at all!!

It is damaging to a Rainbow!

As for the adding dish soap to trap non wet(able) dirt....I just add a few drops of ESSENTIAL OIL........absolutely NO foam and wouldn't the OIL act in the same manner? I also know you can add a drop of JET DRY rinse aid for non wet(able)...But in all honestly, I can't think of anything that I vacuum that is non wet(able), but I add the oil or jet dry anyway.......Even the JET DRY foams if you add too much, so I just add a drop.


Post# 249477 , Reply# 18   9/8/2013 at 15:52 (3,874 days old) by man114 (Buffalo NY)        

I'm not saying a boatload, a drop. You'd be surprised because once you pick up the stuff it kills the foam. Just like when you put your dirty dishes in the sink and the bubbles die down.

I'm not saying give it a good old squirt don't get me wrong.. Perhaps foamy mess was an over exaggeration.

Actually HE laundry detergent would probably be a better alternative due to the foam inhibitors.

As I said I prrobably over exaggerated, but it is messy. I am not talking filling it up with a boatload of detergent so it looks like a washer in a TV sitcom overflowing. I'm talking a drop. HE detergent probably even better due to the lack of foam.

regarding the poor airflow

With any canister, if the airflow is less than expected, you should consider checking the hose for clogs/obstructions. Is the air flow significantly better at the base with the hose detached? Presumably it is safe to run water through the new Rainbow's hose given that it can be used to pick up water. I'm sure there are other tricks to cleaning obstructions from a hose that others can share.

Well, the reason

mark40511's profile picture
I expected EVEN A drop of dish soap to foam up........is the fact that even if I use three drops of jet dry........that will start to FOAM too much......Just three drops, and rinse aid isn't even supposed to foam............So since dish soap IS supposed to foam, I figured even a drop would send it over the edge......I can see how the dirt would stop the foam, but believe it or not, it takes a a few minutes of vacuuming for me before the basin even starts to begin to look dirty.......I guess because I'm OCD so carpets are so clean....

I mean, EVEN the BIG GREEN bottle of Air Freshener from Rexair foams up. The only way I don't get any foam is if I used essential oil or the little bottles of the Rexair scents....I even tried Fabric softener once (the cheap liquid kind) and that foamed like CRAZY! I was shocked because I didn't think that stuff was supposed to foam at all.

I was wondering about a kink in the hose effecting the air flow too. It looks like there might be a kink in the middle of the hose (just above and to the left of the floor tool) but it might just be the way the picture tuned out.

I checked the hose over there is a spot where it's a little uneven it shouldn't effect the flow too badly.

I also ran water through the hose to check for clogs it looks like it just washed the dust on the inside of the hose out the water was a light grey. It was pulling a 2.5 when i straightened the hose it managed a 3 any bends or curves in a hose can effect airflow.

Oh i should add that i cannot get a reading at the inlet because i cannot get a seal on it

I was doing my daily vacuuming this morning at 5 and all this talk about jet dry in the water had me wanting to try it so I did. When I was finished I could see no difference in the water after I was done. My water is surprisingly clean after I vacuum only just slightly cloudy and still able to see through it. Only used two drops and it really didn't foam anymore than the Rainbow fragrances or the green air freshener does. Wanted to ask this question earlier but have been out washing down the house all day. What does the jet dry actually do? Sorry for going off topic.

I'm sorry to go off topic too......

mark40511's profile picture
But....Jet Dry makes the water "wetter". It increases the water's dirty trapping ability. I think oil based fragrances do as well, since the oil allows things to stick more easily to the water? Rainbow even sold this solution called "Aquawet" (not sure if they still do) and I've been told countless times that this is basically just the same thing as "dishwasher rinse aid"

Someone in another forum had mentioned they used Rubbing Alcohol in the dishwasher rinse aid dispenser because it also causes a sheeting action. I would have NEVER in a million years though to do that! It sounds like a good idea.

Then I started wondering if pouring a little rubbing alcohol in the water basin would do the same thing as Jet Dry?

It's really NOT an issue as long as you don't have any non-wettable dirt in your home that you're vacuuming........But it still adds a layer of protection I would think "just in case" something gets vacuumed that's not wettable.


Post# 249933 , Reply# 27   9/11/2013 at 22:42 (3,871 days old) by man114 (Buffalo NY)        

Adding stuff other than fragrances to the water is pointless in terms of cleaning unless you are sucking up stuff like drywall dust. If the water isn't sufficient in terms of holding dirt in quantity get the larger basin or dump it more often. Jet Dry isn't cheap.

Stuff that couldn't be separated with water would be my main concern. Most of it is not ordinary household dirt.

In terms of household dirt collection you're taking a design that dates back to the 1930s. 1930s units are still working. So are ones from 30 years ago. Normal, everyday dust is not an issue for these machines. That is most of what you'll get. If you're sanding drywall, the HEPA will still get it, not good for the machine but that's what will happen.

To me, even selling them, it an expensive machine, you want what it does or you don't. Even an in home demo can't convince you of that.

I've got 2 of them, Dysons, Fantoms, Kirbys and other high end or bagless units, but I still use the Rainbow because upon emptying you don't get a face full of dust and it is cheap on supplies and maintenance. My wife loves it.

Remember it says in the Rainbow owners manual-DO NOT PICK UP DRYWALL,PLASTER DUST or ASH with your Rainbow vacuum.Large amounts of that debris will clog the HEPA filter-so says the Rainbow book.So I don't use a Rainbow to clean up those things.

New (sort of) Rainbow

I agree with you guys. I have NEVER understood why it is such an issue. I only used a vacuum ONE time to pick up just a very small amount of fireplace ash and it RUINED the machine in just a few seconds.
I had cleaned my fireplace with a small broom and used a bagged upright with the hose to just go over and make one last pass. The bag immediately exploded and I had fireplace ash EVERYWHERE from the inside of the outer bag to the underside of the machine and even up into the motor compartment.
Also had a friend who ruined a nice Hoover upright with the carpet powder. It got up into the motor housing, beater bar bearings and both the inner paper bag and outer bag. It was a mess.

I can honestly say as a vac store owner, very few things are worse than a vacuum that has been used to pick up carpet fresh. I absolutely despise seeing them brought in because it always means an extra 20-30 minutes trying to get rid of as much of that powder as possible. That powder sticks to everything and if it's a machine with a bad filtration system ( i.e single cyclone bagless, bagged unit with 1 ply bags) you're guaranteed premature motor failure. Even if it doesn't make it's way into the motor bearings, it will plug the filters causing less air to go through the motor and the less cooling air, the less life the motor will have. I've seen some machines that will be completely coated in the stuff and I've yet to smell any of powdered stuff that actually smells half decent.

We sell a product made by a company called Feather Lite. It's larger granules which helps with 2 things. One, it doesn't hurt the vacuum OR the carpet because of it's larger size and Two, the product hold it's fragrance much better. I've used it in vacuums at home before and even after 3-4 full uses, I can still smell it.

The carpet fresh powders also bind up rollerbrush bearing-making them shot.The stuff is CORROSIVE to metal and even plastic vacuum parts,erodes fans-esp plastic ones.And another weird thing about that stuff-if it stays unpicked up in the carpet-when you do pick it up with another vacuum-smells HORRIBLE-sort of like dirty socks or feet.When I moved into the house I live in now-the former owner used the stuff-his vacuum must not of been very good-left a lot behind-I picked up like 3 SMELLY bagfuls of the stuff with my Royal metal upright.That was my move in vac-that and the metal Royal canister.My Kirbys were packed for the move.Sure the Kirby would have dug out that stuff as well.

mark40511's profile picture
of me being paranoid about picking up non wettable stuff. 99 percent of the time, I don't, but there are a few times that I have run into using my rainbow, I make it to the bathroom to vacuuming the tile floors and notice someone has used Shower to Shower body powder and some of it got on the floor. I'm no chemist, but I would think that would be AS BAD for a vacuum as drywall dust or carpet fresh. So I guess that's why I try to add a little scented oil or jet dry to the water "just in case"..It only take ONE time for that stuff to get into your hepa.

that started using jet dry in the basin to prevent the clear plastic from clouding up. I put it on a clean paper towel & wipe the entire inside, then I wait until it gets dry then I take a wash cloth & wipe any excess that still might be on there.
Using fabric softer WILL cloud the tank not to mention VOID any warranty because fabric softer is very slippery & the rainbow people know what's been vacuumed up.
You can also ad a drop of bleach to kill any micro-organisms that might be in there and never use dish soap, laundry detergent in there because it will cause the inside of the motor to RUST!!! I have seen it at the Rainbow Store....trust me they know what's been used in there when they take it apart and also how it smells becuase it wasn't stored properly. I have seen what sheet rock dust can do, turns the entire inside white of the motor & into the circuit board so...they know what they are talking about.
You can also clean your basin with Mother's Mag Rim Polish, and it does a wonderful job, make sure you get it all off the inside...makes old bowls look new??!! Ahyhow have a good one! Mark D :}

I wouldn't ever use Bleach in a Rainbow . I hate bleach its toxic in my opinion . I would rather use tree tea oil it will kill anything in the Basin

Ruined many a shop vac with fireplace ash but I'll be darned that I did it hundreds upon hundreds of times with a garbage picked Fantom Thunder and it still works. Only issue is if a large coal jammed the hose.

I wouldn't use the Rainbow for it, and personally I wouldn't recommend many machines for it. There used to be an ash vac attachment to do specifically this, dunno if it is still made.

I don't think rubbing alcohol would be a good idea, while it creates sheeting action it disrupts surface tension of water, which would probably hurt the dirt trapping of water. Jet Dry is more of a water softener. Oil would have its own density and would float above the water (or be stirred in in churning air as you can tell when you add an oil based fragrance to this or their aroma therapy machine)

Now if you think its easy to kill these machines, it may rust the motor, may clog the HEPA, but killing the machine is no easy task. I went to someone's house that used one to suck up drywall dust and did so without water. Machine was a mess but still worked, was a single speed E Series.

There are reasons 30 year old Rainbows are usually still working, just like 30 year old Kirbys, they're built well enough to tolerate quite a bit of abuse. You're going to have to do a lot more to kill it than a $50 department store model.

Really my advice would be don't vacuum up drywall dust and fireplace ash & don't store it on the basin if the basin is not 100% dry. If I vacuum every day with it I put the basin in the basement where I rinse it. If I don't use it for a few days I put it back on when it is thoroughly dry.

Other people forget to clean the seperator, usually you don't run into problems with this unless you vacuum up too much stuff without dumping the water.

If you use a fragrance in the water at least you can eliminate the need for carpet fresh. I'd never use that stuff the grit alone can't possibly be good for the carpet, not many machines could pull it up sufficiently.

Peronsally I bought my E Series from a thrift store for $20 in like new condition. I still take care of it as if I paid a lot, knew the machine going in before I got involved with selling them (and already had a D4, also second hand). I'd get many times what I paid in trade for a new one. Despite all that my HEPA filter is in really good shape. They won't pass much dirt to the HEPA if cared for and used properly and mine still has the old brush motor.

I know the rainbow is designed to handle regular household dirt and dust but I have already fired up the woodstove for the season(yes my rainbows never go near the stove) and I get a very fine dust covering everything and I know that some of it is probably ash dust and it just gives me piece of mind to have the jetdry in the water.

must help in *some* ways, otherwise why would Rexair have made this for those occasions?

This is the stuff I was talking about that I've been told is nothing more than dishwasher rinse aid.........Though I can't be sure.

but will all this "Rainbow" talk recently, I'll add to this post.

After having used my Rainbow over 5 years I decided to change the filter. I purchased a "generic filter" on Ebay and I can't tell the difference at all.......

I cut into the hepa and tore it all apart to see what it looked like. It was very hard to tell in the case....It looks worse in the pic than it did in person, but as you can tell, it's not very dirty at all....so perhaps the drop or jetdry helps. The fans aren't dirty either.......

For anybody reading this & wondering about using Jet Dry in the water basin to help make the water more "wettable" & help capture more dust....I just bought a E Series E2 one speed model, & have been experimenting a bit. I have figured out that you can add 1/8 measuring teaspoon of Jet Dry to the water. Using any more than that will cause the water to foam up. Also interesting to note, the shop I bought the Rainbow from says that using 1 tablespoon of Vinegar will also make the water more "wettable" & help reduce the amount of dust that gets passed to the HEPA filter.

I use Sugar

I warm up the water so sugar dissolves easier than cold water. I put 3 teaspoons in warm water and stir it. Then I add it to basin and fill up the basin with water. my fans on D4c and E2 still look cleaned. I had bad luck with jet-dry foaming. lol
