How LiDAR Works: Measuring Light Speed with the First and Best Floor-Washing Robot Vacuum

[@O4C209]

You know it's expensive when they're giving a $500 discount.

[@WoLpH]

It seems to be $1500 normally which so $1000 now I guess? That's a reasonably normal price for a mopping/vacuum of this caliber, similar ones go for similar amounts. The big question is how it compares to other similarly priced machines though, I have a heated mopping/vacuuming robot from dreame that was about $750 or so that does an amazing job, I'm not really sure what could be improved... it already cleans great..

[@solandri69]

The mopping in UV light demo is actually a trick used by vacuum salesmen for decades. One of them came to my parents' house in the '70s. He put a pile of dirt on the carpet and had my mom clean it with the vacuum. Once the dirt was gone, he revealed that he'd disconnected the hose. So all she'd done was spread the dirt out into the carpet with the vacuum's rotating bristles. Spread out enough that you couldn't see it anymore. (He was demonstrating that a vacuum with poor suction could look like it was cleaning well, even though it wasn't.)

[@Sonny_McMacsson]

He's now Kirby man

[@kylek29]

First "floor washing robot" ... I think Eufy is being a little generous to themselves with these feature descriptions. Is it innovative in how it mops? Sure. But it's not the first to mop nor is it the first all-in-one base, and the shape is an evolution of the classic "D" shape, which has existed for a decade or so going back to the NEATO's. Don't get me wrong, I have a Eufy robot in my house, but I do feel the need to call out marketing when they decide to jump the shark a little.

Isaac Arthur did a 'fun' video on the death of privacy recently. He's usually who I go to to restore my faith in humanity and even he's starting to be a doomer.

[@guiorgy]

Just an FYI, Eufy, a sub-brand of Anker, had some false marketing and major security flaws with their cameras, which they refused to acknowledge untill it blew too big. I don't know if they have changed or not, but I don't care, I'm never trusting anything Eufy

[@vishnuranjan1446]

It's also the channel's first video that has more marketing content than science. 😅

[@coleballenger4595]

No, there was also that vid about the weird desk.

[@WumbologyPHD]

Eufy telling me that it doesn't store pictures of my home means absolutely nothing. Remember when they said their camera connections were encrypted, and when they were called out they doubled down before attempting to fix it? Remember they never even apologized or took responsibility. Just remember that anybody on the internet with the right link could view your home camera feeds without any authentication. Absolutely despicable security. I would not trust this company with anything.

[@Ekipsogel]

Why is it streaming pictures anyway? It seems big enough for some extra RAM to do image processing locally.

[@davidcampbell2143]

This is not ok. And I don't mean the fact that you make content that is payed advertisement.

​@@ramteja1550 good point. First of all, the fact that you (and probably lots of others) don't is exactly why this is just not ok. Second, If you look at other videos of Action Lab, you can spot differences in the use of certain words, for instance superlatives: the best, Incredible, etc, or 'factual comparisons: months before competitors, cleanest, etc. Those are not words and frases commonly used in the videos, or in scientific videos in general, because the point of these videos is to give a new factual description of a certain fenomenen, not to promote a certain product opposed to others.

[@paulkocyla1343]

The "3D matrix" sensor looks like it has only a single camera, so I don' t think it' s a stereoscopic approach. The bluish squares beside the camera might be diffraction grids. I guess there is a laser that is projecting a cloud of dots onto the wall, and there is a single camera that sees this image. The distance of an object is then estimated by measuring the 2D distance between the projected dots on the camera image. The further away the object is, the further away from each other the dots appear on the image. --- Alternative approach: The infrared laser lines that are used for the time of flight detection are beeing used together with the camera: When the camera and the laser are tilted at an angle, and object comes nearer, the laser line will be distorted in the image, which can be used to estimate the distance. This technique is quite conservative, but might work in this case.

I've had a $79 Euphy G30 Verge for years, dumb little bot works pretty good. It only vacuums. Recently got a Roborok S7 that does mopping and vacuuming. It's very meh. Gets stuck more than the dumb bot despite the lidar. Had to setup a ton of no-go zones to prevent that. Its mopping is just dragging a damp cloth over the hard floors. It also drags it along the carpet a bit. It was just under $300. Another $200 would've gotten a base station to clean out the dust trap, not worth it. It is one of the highest rated, best bang for your buck, bots on the market. Didn't see this Euphy on those lists, possibly too new. This Euphy bot with base station is $1500. Really not worth it imo. IDK about the square design, it'll have to back out of corners instead of just turning in them while the broom reaches in to clean. Less efficient. Cameras recording my whole home? No thanks. I value privacy. Lidar alone, or even just bump sensor alone, is enough.
