Please don’t take everything you read on the internet at face value. Every decently sized city there has at least one DNS, Eldorado and MVideo electronics chain:
I visited Russia in 2013 and 2014, and there were a lot of gritty places, but availability of modern retail shops, goods, etc. was basically the same as places in Europe at that time. My kid travelled there last summer and said the sanctions are having an impact, but a lot of it is on the order of, for example, McDonald's changing the sign outside to some knockoff brand and sourcing their ground beef and packaging from somewhere else.
Cities all over the country as small as 50k have these stores and their competitors where you can buy fresh Mexican avocados and sparkling new Korean appliances.
Or, if you don’t want to go in store you can buy any item under the sun on Wildberries, Ozon and have it delivered to your front door.
The fact that inventory in stores, or delivery apps exist does not help when a lot of people in rural Russia can't afford it, as one of the sibling comments points out.
I've also heard (from Russians) that water access in rural Russia is poor.
To use a washing machine you need access to running water, sewage and electricity. The first two of those are still not available in large parts of the country.
And large portions of the population still cannot afford one.
The intersection of those two frequently ends up in the army, as that is the only social mobility they know.
