Not sure that's actually a Lidar unit under the cover. Looks more like a roomba to me.

Xiaomi is getting into lots of electronic products. People like their products because their quality is better than other Chinese manufacturers.

The price is for distribution in China. Marketing, shipping, and distribution costs could raise the price closer to competition in the U.S., though at the low end. It looks like they have saved by using a smartphone for the control panel, similar to Dyson. This is an obvious offset to the cost of the WiFi radio, besides more capable display. There seem to be various connection and setup problems with all the WiFi equipped vacuums out, at least for some people.
In China they are competing with Ecovacs, some of whose models have been sold at RobotShop.

- 12 sensors including Laser Distance Sensor (LDS), ultrasonic radar sensor, cliff sensor, gyroscope and accelerometer
- LDS developed entirely in-house: able to scan its surroundings 360 degrees, 1800 times/sec, similar to the laser guiding system used by self-driving cars
- 3 dedicated processors and a total of 4 CPU cores for real-time mapping and positioning
- Use of Simultaneous Localization and Mapping (SLAM) algorithm to calculate optimized cleaning paths
- Powerful Nidec brushless DC motor (up to 1800Pa air pressure)
- Ultra-quiet airflow
- Main hover brush automagically adjusts height to create a tight seal with floor for thorough dirt pick-up on uneven surfaces
- Maintains 1cm distance from walls for the side brush to effectively clean near walls
- 5200mAh battery yields up to 2.5 hours of cleaning on a single charge
- Mi Home app integration lets you control robot remotely and set scheduled cleaning. It also shows you the path in real-time and estimates how long it’ll take to completely clean the home
- Smart return brings back Mi Robot Vacuum to its charging dock when low power is detected and lets it go back to its last cleaning location once charged
Mi Robot Vacuum will be available in China on 6 September

[edit] scanning 1800 times per second likely means number of points per second, giving 5 RPM, 360 points per revolution, similar Neato.

I don't speak Mandarin, but there's a pretty complete un-boxing and demonstration at:
https://youtu.be/eSHaXONwPXI?t=33s

To me, it looks much more like a Neato than a Roomba. I'd be curious about possible patent violations ...

That's a Neato Roomba

The video looks interesting, supposedly the mapping for this is really great and you can see it map your space live.

Pricing: A Xiaomi smartphone in Amazon U.S. stock, including shipping, lists only 11 per cent more than ebay sources in China, including shipping (which is always very cheap from China, maybe subsidized). That would put the vacuum at $282 in the U.S. at Amazon when distributed, with Best Buy usually similar.
Best Buy has Neato XV's on clearance at $251. The new cheaper Botvac's may finally replace that older line.
Note Botvac has a wider brush than the XV and probably Xiaomi's, and the higher priced Samsung's still wider -- you pay for capacity.

They quote fan output, but that will not translate to better cleaning than Roomba, Neato, Samsung, etc....

The design will not make the most of its fan power. So very new too.

It's basically just cheap

The other Chinese company Ecovacs has their laser model expected October 2016, but at much higher price, mentioned in Europe 499 Euros. It has taken some years to bring to market after a prototype show demo mentioned in other threads. Some of their models were carried by Robotshop.

After Neato had some reliability issues with the first-generation Botvacs, Costco Canada stopped carrying the Neato brand. They replaced the Neato lineup with the Ecovacs DEEBOT DM82, DM85 and D79 models.

Maybe Costco will also carry the upcoming R95 that glnc222 mentioned?

The Xiaomi MIJIA Mi Robot Vacuum is now listed for sale, but currently on back order:
http://xiaomi-mi.com/mi-smart-home/xiao ... ot-vacuum/
Using the pre-order menu, shipping to USA costs $80 to $122, Canada costs $113, and the UK costs $80 to $118. That's a pretty hefty shipping fee!

Individual unit shipping is more costly than bulk freight to distributors. You also cannot get a Square Trade warranty on individually imported items, nor Geek Squad etc. There are always new product offers to ship from foreign makers, at premium prices for the avid fans. You might need a wall plug adapter.

Yeah, the current pricing (with shipping) for the Xiaomi MIJIA Mi Robot Vacuum is the same as a Neato Botvac™ D75 Robot Vacuum. Granted that the Mi has WiFi with tracking (very cool) but the Neato has a solid track record.

Photos don't reveal whether either new product suffers from the "bumper too high" syndrome infecting the engineering profession, maybe transmitted by passing poorly designed robots hand to hand.

Yeah, the 12 cm high Dyson 360 Eye is a really bad example of this. Apparently, the Xiaomi MIJIA Mi is 9.65 cm high, compared with 10 cm for the Neato BotVac and 9.15 cm for the Roomba 980.

Here's a comparison of the Xiaomi Mi Robot Vacuum vs. iRobot Roomba, Dyson 360 Eye

I meant the bottom edge clearance which allows bots to climb things they cannot get off, like cats in trees.
I think the Powerbot is the tallest, and nicely avoids overhead traps. No matter how thin, there always seems to be some furniture too low, so getting under everything is up to particular interiors. I would rather have effective cleaning than fit under everything.
