What is the difference between Xiaomi Roborock S6 and S6 Pure?

Essentially, the size of the dust container and the water tank are different: The S6 has a larger dust container, while the S6 Pure has a larger water tank. All other differences are just hardly noticeable. The S6 Pure is a kind of light variant of the S6 and should therefore usually be a bit cheaper than the S6. Here is an overview of all the differences:

	S6 Pure	S6
Water tank	180ml	160ml
Dust bin	460ml	480ml
Weight	3.2kg	3.6kg
Dimensions	35 x 35 x 9.65 cm	35.3 x 35.3 x 9.65 cm
Charging station	smaller than the predecessor S5, without cable management, underlay pad less stable	larger, with cable management and more stable attached underlay pad
Charge time	4-6h	3-4h
Buttons	Spot cleaning can only be activated via key combination	exclusive spot cleaning button
Sensors	4 sensors, rear crash sensors missing	6 sensors

The manufacturer states that a couple of the materials are different, which probably explains the weight difference. Visually, the two look very similar:

Wieso gibt es diese Unterscheidung?

Roborock develops and manufactures robot vacuums as an ODM (Original Design Manufacturer) arrangement for Xiaomi, and Xiaomi markets these models and provides after-sales service under the Xiaomi brand. Xiaomi is responsible for sales and warranty. Roborock also develops other models independently, which includes the S6 Pure.

The current price comparison shows, contrary to the MSRP, that you can get the S6 cheaper in this country, so I recommend buying it or alternatively the Roborock S5 Max. Pragmatically, I would say if the S6 Pure is significantly cheaper than the S6, buy the S6 Pure. If they are the same, buy the S6 and if the S5 Max costs the same as the other two, buy the S5 Max. In other words, the S5 Max is the best package, the S6 is the second best, and the S6 Pure is the third best in this selection. However, all three perform at a high robot vacuum level and offer very good results.
