Worth it on these?

I saw that earlier today on the TCW page. How old are they? My first thought was wow got money's worth on these.

These?

 

[Earl Weiss]

I have no idea how old they are. But this was an example of what mine often look like when they fail, so i could never justify the time needed for periodic brush replacement and whatever the life extension might be.

Yep, MEP thanks for posting the pic here.

Those must be getting wet somehow. We have some that are 15 years old and they look new compared to those. Are your customers sucking up lots of liquid?

They must be vacuuming de-icing stuff out of their carpets and floormats.

Wouldn't be surprising. Carpets have lots of Salt stains after a winter so there is plenty of residue to vacuum up. This is aside from if they are shampooing first.

Earl, are your vac bags installed properly or maybe they have holes in them? A small space will expose your motors to more moisture(I’m sure you know this already but putting it out there for other vac novices)

I need to replace brushes 3-4 times a year and my motors never look like that and some are 10+ years old.

When there is a bag issue - it is rarely subtle. I have screens below motors so usually they get clogged and there is lack of suction. If the screen fails the motors get a bunch of stuff in them and typically make an awful racket.

Why would a hole in the filter bag let moisture through to the motors? The filters are full of holes or air couldn't flow through them.

The same reason as if there were no bags at all inside the vacuum. Maybe my monorail vacs are different than yours but my bags are cloth without any small holes in them.

All in all I think the point is that conditions vary. For some, spending time and money to replace vac motor brushes to extend the life for whatever may well be worth it. For instance I use a vac motor (not the type pictured) as a blower in my tunnel to create bubbles. They went bad about every 100K cycles, but now replacing brushes every 50, 000 cycles they seem to be well past 200,000 cycles. But when my vac motors go bad and often look like the ones pictured, i see no point in spending time or money to prolong them since other stuff would go bad shortly.
Winter Salty moisture in Carpets may very well be the culprit.

I've never heard of somebody replacing rushes every 90 days. You must do 5k/week on vacs...!!

We are probably replacing our brushes every 3 or 4 months at one of our locations. 7 Coleman combo vacs, Kleen rite motors, vacs cleaned monthly. We are a pretty busy location.

I have 16 free vacuums at my location. They stay very busy between my 7 bay self serve and my 100' tunnel. They all don't get the same exact usage so I rather just replace the brushes that are very worn then have a motor blow up.
