BTW:
You can get now 'Dreame X40 Ultra Complete' below 1000 (or 999) as a Black Friday deal on the manufacturer page,
or 998 at Amazon De (as a normal price).

P.S. I wonder why Digitec / Galaxus, and a few other Swiss shops, still offer it for 34+ % more.

The dreame L 40 also has voice control, so it is also a little higher than the X 40.
The Ultra comes with fewer accessories

The x40 has a slightly stronger suction power (only really useful for carpets) and washes the mops with 5° warmer water. No differences that justify the price. I can fully recommend the L40 Ultra!
