The delivery was done in two steps: the first package contained the accessories, a few days later the package with the toilet arrived (20kg heavy, my poor postman).
The assembly was quickly done thanks to the foolproof instructions, really very detailed and illustrated. The only annoying part was the box with the parts INSIDE the drum of the cat toilet. A small tip: you can take it out, then it will surely be easier... I didn't know, so I took the box apart inside the drum and reached my goal that way.
The installation is also self-explanatory, otherwise also described in detail in the instructions. I simply filled in the cat litter and tried all the buttons one after the other. After a few minutes of fascinating admiration of the simple technology with which the machine operates, as well as the skeptical observation of my cats, partly in meerkat position, the acid test followed.
Both cats accepted the toilet during the day and at least the more particular one certainly doesn't want to do without it anymore.
I personally am happy every day about my new diligent household helper, truly a worthwhile investment. If it wants something from me beeps or lights up, otherwise it cheerfully does what it should. I am still curious about the monthly basic cleaning with litter change. But that will certainly be as easy as everything else. :-D
