Ideally you need either the HD model (400rpm) or the DF model (800rpm)
Both of these can take horse shoe weights adding up to an additional 35kg.
The DF can take a lot more. I have ran ours removing paint while stood on top of it.
They are okay on a flat floor. Cant handle lippage.
The cimex was the first planetary machine available. They sold the design to DK Holdings who built their Tornado line which had variable speed, bigger motor and more weight.
The cyclone model will work but it doesnt like extra weight as it has the smallest motor in the line up.
It doesnt take a splash skirt either unfortunately.
It is 400rpm and planetary though so if it was a maintenance type job it could handle it fairly effortlessly.
We used to use them quite a bit but moved to a Levighator as it can do a wider range of tasks.
That said they are both out on a concrete polishing job today to do the final polishing after the levighator had ground it flat removing all the paint and self leveller.
