The difference is that the "Complete" comes with a replacement set with EXTRA wishmops, suction rolls, cleaning fluid, dust bag, filter etc etc.. So you already have the consumer parts as a replacement. I can definitely recommend it. ✌️

Small tip: The replacement set is available from the Swiss competition for less than 100.

I can confirm that "Complete" still comes with an accessory set.

The "Complete" comes with an accessory kit that goes beyond the standard scope of delivery: additional mop pads, cleaning fluid, replacement brushes, dust bag and filter for the base station as well as a replacement roller.
