There is a video of my 21 MKII vs 15 MKII. My 15 harly spins that white Rupes pad, my 21 have no problems whatsoever and even my Duetto performs a lot better than my 15 MKII. It has been like that since new and i have done few cars with it. Faulty unit?

That's definitely faulty. My 15ES doesn't even stall like that heck my DAS6 doesn't stall that easily. Interesting as the motor sounds like its spinning fine but theres no pad rotation.

Have you tried a washer mod?
Even without, there's something not right. Definitely contact Rupes.

Get a 3401, end of stalling problems.

This^^^
I have Flex and Rupes machines and although I've gotten used to manipulating the Rupes to stay spinning I always reach for my flex machines.

Well my friend who is a pro detailer and also owns Detailing store tested it with same batch 15 Mk2 and they were identical and both were better than mk1. So i thought the machine is ok and works as it should, but i have seen many videos online where 15mk2 is just so much more powerful than mine were so i sold my old unit and bought a new one and the difference is huge! My new 15 mk2 feels a lot like my 21mk2 and not stalling problems whatsoever. Also it sounds bit different, more powerfull i would say and its not as silky smooth, i mean it is very smooth but my old was kinda like too smooth. My new 15 mk2 is stronger on speed 3 than my old was with speed 6!!!

I am not the only one who have seen so big difference between two 15 mk2 units:

Do you use a Rupes Bigfoot mk2 15? Is your machine faulty? - Detailing World (http://www.detailingworld.co.uk/forum/showthread.php?t=393314)

I wonder why this is happening? Anyway im now happy that i have great 15 and 21 Rupes.

Anyone else having stalling issues? If so, how was it remedied? I bought the LHR15 MK2 after reading good things about Rupes in general. I've done two details with the machine within the last couple months and the results were great, but I did find corrections took longer than expected. Well today I tried polishing the hood of my car. I marked the backing plate with sharpies and went to town. It was then I realize the machine slows down considerably with light-to-moderate pressure. I'm using Rupes pad and polish.

Mine sort of does this:

I'll record my machine in motion and then you guys can see whether it's faulty or not. I still have warranty, but I rather not send it in if it's not 'defective' per Rupes' definition.
