The Qrevo S5V is half the price of Roborock’s best robot vacuums, but it’s still a top-tier cleaner

androidauthority.com Unknown 2025-07-21 15:00:21

Roborock Qrevo S5V The Roborock Qrevo S5V is a well-priced robot vacuum and a highly-capable autonomous floor cleaning system. It cleans hard floors and carpets very well, and gets into the corners and underneath furniture with ease. Higher-end models boast greater capacities, but this bot can get the job done in the average home without breaking the bank. I’ve tested the very best robot vacs that Roborock has to offer — from the do-it-all Saros 10R to the all-that-plus-a-robot-arm Saros Z70 —

Two hours into my gaming preview of Dying Light: The Beast, I was jogging through a beautiful woodland dotted with cabins and park benches -- a spot that would make for a lovely vacation, if not for the hordes of zombies wandering all over. Despite stealthily creeping around, I was spotted by a large group and frantically fended them off with a shovel, growing more desperate and overwhelmed -- until my rage meter maxed out and I became a beast.

What happens when housing prices go down?

news.ycombinator.com Charles Marohn 2025-07-21 17:16:42

There’s a theory about housing that has taken hold with a kind of religious fervor: If you want to make housing more affordable, just build more of it. Supply and demand. Simple economics. This narrative is now dominating housing policy discussion across the political spectrum. Deregulate, upzone, speed up approvals, let the market work. And if you build enough homes, the theory goes, prices will come down. But here’s the question almost no one asks: What happens when prices actually start to

You can now buy eggs from in-ovo sexed hens

In polling, only 10% of Americans correctly identify that male chicks in the egg industry are killed shortly after hatching. A plurality mistakenly believe these chicks are raised for meat, and another 10% even think that male chickens can lay eggs. Most people are surprised, and often disturbed, to learn the truth: in the United States alone, approximately 350 million male chicks are routinely culled each year, typically by methods such as maceration (being ground up alive).

Around the year 1404, Christine de Pizan completed her work, Livre des faits et bonnes mœurs du sage roy Charles V. It was both a biography of the French king who reigned from 1364 to 1380 and a guide to how an ideal monarch should live and rule. Christine had a good vantage point to tell this story.
