I bought 4 years ago the same robot MUM 4780. The electronic power control passed away and there was only 2 speeds that worked. The new robot has the same features without electronics. I hope it will last longer. The price is advantageous and I could keep the accessories that I bought: mixer, grinder, blender. That is the advantage.
My wife is very satisfied for the pie dough and the comprehensive accessories even if the assembly is sometimes a bit complex ... The equipment is compact and really versatile. I would prefer the white back but there is no choice.
