Vacuum Cleaners Discussions

Technically, the Rainbow vacuum was the first to not lose suction.  It uses a more primitive dual cyclone design with water as a pre-filter.   If the Rainbow didn't have such a ridiculously high price and clumsy power nozzle, it would be a pretty good vacuum.  I don't know why they require you to hold a button down to keep the power nozzle operating.  One would think that they would use a simple 2-way switch.  All that on/off cycling can't possibly be good for the power nozzle motor.   The Rainbow uses an innovative brushless motor.  It would be a pretty good $800 vacuum with a better power nozzle. 

Rainbow owner here..E2 2 speed. I just wanted to say that at my job they are forcing us overtime six days a week and I havn't had time to get out the rainbow because I agree to get it out is really an all day event! So I been using the Kenmore canister because it's quicker. But..Since i havn't used it in a couple of months...I can tell a pretty big difference with dust..I'm pretty good at changing the water way before it gets gross. But according to what I've read..even with doing that my machine will still get dirty inside. I notice nothing but a clean smell when turned on..SO if these are so vile inside..shouldnt  I smell it? Anyway..it is a pain to use but I still would not want to be without it to give the house a good cleaning a few times a year. Theres a big difference to me..The house stays cleaner longer when it's used.

Hi Mark,given that your e-2 is under a year old,the lower endof the motor should still be nice and clean,you are one of the few that use your machine properly.I would suggest changing the internal hepa filter,there is also one inside the machine,the exhaust filter is on the back of the machine behind the the grill where you wrap the cord around the hooks,that danged machine should have a cord reel for that price.For the price of this portable cleaner, and others, CENTRAL VACUUMS are  the way to go.

Hi mole,

Speaking of central vacuum systems, are there any self-contained types that you might recommend for condo or co-op owners?

Venson

Hi Venson, there are a few centrals that would merit looking into for condo applications.

1 the sweep away by GALAXIE SYSTEMS[very new to the market]

2 the vax system by nutone

3 the condo lux by aerus/electrolux

There are two hepa filters? I only see one....and it's still bright white..I looked through the manual and see nothing about a 2nd hepa. How do I change it and how often should it be changed when machine is used properly? For those who rebuild Rainbows..I'd be curious to see what the inside of a properly used one looks like after years of use.

Hi Mark,it's called an internal air filter,part#R-7287es.The unit has to come apart to change it.It's not listed in the manual,and even the rainbow sales people dont know it's there because rexair doesnt want them to know about it.So much for water filtering the air..................

I did some looking and found that the E1 Rainbow has an internal cooling filter but not the E2.

Hi Mark,according to rexair in troy your e2 uses an internal cooling filter,sort of looks like an automotive,round air cleaner........

I noticed a website offering every product for eash model...The e1 model they offered the internal cooling filter...But for the e2..they didn't..SO this internal cooling..Is this hepa?

Hi Mark,no it's not a hepa rated filter,my only quess would be a pre hepa filter,that is used for cooling and air deflection,the reason for it being there is really undefined,My figuring is for when consumer reports rates the machine,it cuts down on the emmisions for the period of the testing.
