Roborock S4 Max Floor Vacuum, docking/charging station, and 1 additional filter.

Used it for about 1 year and has been sitting in storage. Worked very well, but didn't need it once we got a dyson hand vac. I did a deep clean of the brushes, filters, and dustbin, but you can see there are still some scuff marks on the front and top. Must download Roborock app to use, and then you pair it with your wifi. This model is no longer produced by Roborock. Originally was $380, but looks like it typically retails as used for ~$250.
