Yeah @graydavis, a $15 probe matching temps for 8 hours kind of proves paying more isn't always better.

I've noticed this same gatekeeping thing at my local coffee shop where regulars scoff at anyone ordering "basic lattes" like it's some kind of personal flaw. It's totally the same pattern of making people feel unwelcome for not meeting random made-up standards.

At least poodle curls are curls, mine just turned into a fuzzy mess.

Tbh though, is the Interspiro actually worth the hype or just new gear bias?

The bag mops really do work if you know what you're doing, and @diana_black I get why people love flat mops but they just don't handle grout the same way. I think the issue is most folks don't realize how wet their mop actually is when they start - you gotta squeeze it almost dry then let the floor tell you if it's right. With grout especially, all that smearing from a flat mop just makes the problem worse over time cause it packs dirt down in there. A string mop with hot water and a good wring gets right into those lines without leaving residue, at least in my experience.
