Choosing a used commercial food processor for food preparation processing usually comes down to one question: does your day run on batches or on a continuous flow of prepped ingredients? The two units here answer that differently. The Fii Model K8700 is a continuous feed processor with dicing, grating, and slicing discs, priced at USD 152.10. The Robot Coupe R100 Plus is a 2.5 qt combination processor with a pulse speed, priced at USD 299.00. The USD 146.90 spread between them means the choice is as much about workflow as it is about budget.
Quick verdict
If most of your prep is high-volume slicing, dicing, and grating, the Fii K8700 puts the cutting discs you need into one set for the lower end of the price spread. If your work is more batch-oriented and you want a contained bowl with pulse control, the Robot Coupe R100 Plus is the stronger buy-you pay more, but you get a 2.5 qt combination processor that is ready to run.

Where the Fii K8700 wins
The Fii is aimed at kitchens that need a lot of uniformly processed pieces in a hurry. Its continuous feed design pushes ingredients through the cutting discs and into the collection bin, so you can keep loading while it works. The set includes multiple interchangeable blades, the original manual, and is described as tested and working. If your menu involves big batches of vegetables for soups, salads, or prep lists, this is the more direct tool and it sits at the lower end of the price spread.
Where the Robot Coupe R100 Plus wins
The Robot Coupe is the choice when you want a contained 2.5 qt work bowl rather than continuous output. It is a combination processor with one speed plus pulse, which gives you more control for chopping, mincing, and small-batch work. It comes from the original owner, was used very little, and is fully working with a modification that lets the bowl function in any position. You also get the feeder/pusher accessories, one cutting blade, and the original manual, and more cutting wheels can be purchased if you want to expand the set.
Product notes
Fii Model K8700 Commercial Food Processor Dicer Grater Slicer Set - TESTED

The Fii K8700 is a practical way to bring dicing, grating, and slicing into one preowned setup. The continuous feed design means you are feeding ingredients through the cutting discs into the collection bin, which suits kitchens with steady prep volume. The listing includes several interchangeable discs, the original instruction manual, and the unit is described as tested and working. On the other hand, the format is not a batch bowl. If your work is small-quantity mixing or you want to pulse in a contained bowl, the Fii's continuous feed layout will not feel as natural. It is a used unit, so it may not have the same service life as a brand-new machine, and the focus is firmly on slicing, dicing, and grating rather than bowl processing.
Robot Coupe R100 Plus 2.5 Qt Commercial Food Processor w/mod Fully Working

The Robot Coupe R100 Plus is the more flexible of the two if your prep happens in batches. With a 2.5 qt bowl, one speed plus pulse, and a combination processor format, it can handle chopping and mixing in a contained space instead of feeding ingredients through a chute. This unit comes from the original owner, was used very little, and is fully working with a modification: the pin is permanently engaged so the bowl functions with the lid in any position. That means you do need to be careful to keep the lid on whenever running it. It comes with the original manual, one cutting blade, feeder/pusher accessories, and more cutting wheels can be bought separately. The trade-off is the higher end of the price spread, plus a small crack in one pusher and extra cutouts in the bowl that do not affect operation.
Final choice by use case
For continuous, high-volume dicing, grating, and slicing on a tighter equipment budget, the Fii K8700 is the natural fit. For contained batch work, pulse control, and a compact 2.5 qt bowl that is ready to use out of the box, the Robot Coupe R100 Plus is worth the higher price. The real decision is less about which is 'better' and more about whether your kitchen processes a flow into a bin or works bowl by bowl.
