Hi Guys,

A little time last couple of days for some spring cleaning. I had not used the Rainbow SRX for a long time and decided to put the updated separator in my machine. While they look similar there are differences and in my machine the noise reduction and overall sound of the machine are noticeable. So much quieter and smoother sounding actually pretty surprised. The whine mine had kinda that high pitch sound of a Lux VM3 are gone. Very pleased it's quieter than my E2 Black.

This machine is still a bit under powered but I think it has more power as the fins are not as long and the grooves inside it where it slides on the shaft are gone. Might be my imagination but it runs a lot better so do the upgrade if you have one. Love the hose and water basin set up but it needs a little deeper well in the dolly to take that extra .5 quart like the E2B. I can't say enough about the heavy duty brush strip upgrade and removing the clear ribber strip on the front rollers it makes a world of difference, but does not make up for poor sealing and a lousy base plate design. If you upgrade the roller, pay attention to the ones that are already in it and do one side at a time. Funeral director learned the hard way if you remove all brushes at the same time it is VERY difficult to get back together.

After vacuuming with the Marin/SeB 236 on my white rugs, there is a noticeable difference in the appearance of my three rooms of carpet. Pearl white colored carpets like a GMC pick up are difficult to take care of but the difference is very noticeable as is also evident on my LL Bean navy Mud Hog door mat. Much brighter going over this rug behind the SEB 236 as well. Is it a well designed nozzle? No but it has super agitation which helps the SRX a bit.

Finally I find the build quality good on mine compared to the previous no squeaks or creaks and the now hose connection is super. I think its a shame Rainbow didn't try the SRX before they started manufacturing it. Putting a motor in it would have done wonders for its performance.

Supposedly the SRX got an updated motor as well. From what I can tell from a previous thred several things must've been changed and they are as followed:
the power nozzle (the obvious one)
the separator
and the motor.

I can see the power nozzle getting updated but whats the reason for updating the separator and the motor?

Updates to SRX


I spoke with a Rainbow guy a couple of days ago and he said this about the separator update. Apparently the redesign (looks different inside) and it is a little shorter on the vanes and fits significantly tighter on the shaft and seals tighter to protect the motor. It also lovers noise and pitch so I am beyond pleased.

The parts are said to be avail for the new generation SRX power nozzle so I guess you could order the blue wheels and blue/black top cover and put it on an E2 Black nozzle as he didn't think there were any other changes than that. His experience with the SRX PN-3 with 35 years at Rainbow was bad and was glad to see it gone. Apparently they had lots of bearing issues and housing issues from hair entanglement.

He thought they are tinkering with the motor but has not seen a performance improvement as of yet.
