I’m sure it’s just an example but being european I am surprised at the 10kg load. Most people I know hover around ~5-7 kg max capacity for their washing machines. They’re usually placed in bathrooms or kitchens since not a lot of people have space for a separate washing machine room since also not a lot of people have dryers in the EU (at least they’re not standard, they’re considered extra).
Taking a random appliance vendor's list of machines, there are a good few 9 or 10kg ones, but 6-7kg is also common: https://powercity.ie/groups/view?grp=40&class=01 (the very most expensive one they sell does _18kg_; I had no idea that was a thing...)
Not your point but just adding my two eurocents
