I work in a store that's half appliances and half grills - mostly Weber and Napoleon with a few other brands
I had a customer today who spent almost 1,800 Euros on some Napoleon grill. We don't even offer a washer that expensive and if we did, no one would pay that amount of money.
It's crazy to me how much money customers spend on these grills that are realistically used for maybe only 1/4 of the year. Similarly, people are willing to spend a little more on ovens. I guess it's because they actually <span style="text-decoration: underline;">want</span> to BBQ and eat. It's an enjoyable thing to do. Fancy coffee machines or food processors would also fall in that category.
But washers and dryers? Eww, yuck. That's a chore they want nothing to do with. So they gravitate towards the cheapest white box they can find that'll spin their clothes in a circle, while having great energy efficiency... because, well, energy needs to be saved. Never mind that gasoline is crazy expensive; people are still speeding down the highway like lunatics. But washing laundry, yeah, that's where the big savings are at.
Now, some customers will say that their old machine lasted 20 or 30 years. But it is generally accepted that their new purchase won't last as long. Maybe I should do an experiment and tell them to purchase a commercial machine for upwards of 2,000 Euros, which might last them that long again. But really, no one would do that. The vast, vast majority of people rather junk a cheap machine every so often that to make an investment in high quality.
To add to what Louis said about margins: well, by selling that one grill, I have probably generated more revenue than by selling ten washers. While a grill might have a margin of around 30% or more, appliances are usually around 5 to 10 % (if that).
