For those who have upgraded to the BOSS

Is the brush issue only with the G21 or does it also apply to the G15? When you say wears out fast, what would you estimate that to be in hours of use?

I've had to replace both my g15 and g21 since I've had them and the g15 is going back again. Idk what's wrong with them but it makes a grinding sound again

Hi ScottH,

I bought mine around end of April. Replaced the brushes once around July. So I would say all depending on how many cars you will be doing. from end of April to July roughly 3 months past by and I had done 15 cars during the week-end only. So that roughly 14 week-ends at around 1 car per week-end. So you might say that the BOSS was being used quite often to full potential. I live in a very humid area in Canada (Ottawa/Gatineau). Our humidity factor has roughly an increase of 8-10 degrees.
 
What are the warning signs/symptoms that the brushes are starting to go out? And do you change them yourself, or do you send it in for repair?

Yea I just checked to make sure I hadn't lost them... I have 2 sets of brushes, 4 washers, 1 extra backing plate screw, 3 tubes of silicone grease, and 1 allen wrench so I'm good.

But that still doesn't answer my question, what are the early warning signs? And do you change out the brushes yourself, or is it something that requires the polisher to be sent back for them to do for you?

Yes it is something you can do yourself in less than 5 minutes. I used a small needle nosed plier to remove and install them. Check YouTube I am sure there must be a video. As far as warning signs, the Motor on mine had very little spin/power to it. So I unplugged it and changed the brushes and was 100% operational in a few mins. BTW this was on a GG6 but that doesn't matter - same process. Haven't had to change them on my G15 yet.

Warning signs is that when you press the power button to turn the machine on sometimes it will power the machine sometimes it will not, or when you are working with the machine the power will skip.

You can easily change the brushes yourself. You have 2 screws on each side of the machine. Just unscrew one at a time and replace the brushes. It's an in and out process.

I take it they'll both go out at the same time? Or is it just recommended to change them both just like I would spark plugs?
 
I don't know if they wear at the same exact rate but I would change they at the same time - that is what I did

So it's a dc motor. The brushes ride on a commutator.They ride in the same track just opposing sides of the commutator. When you change a brush you change them both. When you do you can blow compressed air inside to get some of the dust out. That will help the brushes. Dust is like sandpaper to carbon brushes. Also when you have the port open shine a light in and see what the commutatot looks like. If it's blued or has streaking or grooving. That is a huge indicator that it isn't running optimally and has a power issue. The commutator will look like a solid piece of copper but it will have a thin layer of Formica in between all of them

Thank you everyone for the input. I ended up staying with the GG6. Should receive my replacement soon.

if i could only have one polisher this would probably be it. with the right products and pads there really isn't much the GG6 can't do. with the latest (evergrowing) technology in car care these days, i think we are spoiled compared to what limited resources were available many years ago...
