News Upgrade version of the Xiaomi Mi Robot 1S vacuum robot launched for $255

The Chinese tech giant never tires of developing: Xiaomi launches an improved version of the Mi Robot 1S. It features minimally more suction power, a wiping function with a large water tank and an improved laser distance sensor (LDS). A sensible upgrade? We summarize what is known so far.

The technical data sheet still has to prove itself in practice, but the robot is noticeably slightly flatter and lighter than its predecessor.

Sensible upgrade to the 1S?

Laser room measurement via LDS, mapping, room division… The list of concentrated vacuum robot technology in the new version is long. In fact, the upgrade was only optimized, but (as of now) nothing was functionally removed. Accordingly, we will deal here with the differences, for all further information we recommend a look at the review of the Mi Robot 1S.

The obvious difference: the new model is in black. But it should also come in white.

The suction power has been increased to 2100 pa – the current best value for vacuum robots. This is only 100 pa more than its predecessor, but at least the 2000 mark has now been broken for the first time. The laser distance sensor has also been optimised and is now to be able to detect obstacles and contours up to a distance of 8 m.

The LDS was further revised.

Wiping, vacuuming or both?

Using an app, the user can manually set which of the three different working modes he wants to use: pure wiping, pure vacuuming and simultaneous vacuuming and wiping. However, you will probably have to buy the wiping accessories yourself (at least in China), but this may change in the next few weeks. We could be talking about a 0.55 l water tank, which is very large compared to other models. The dust chamber comes in the same size, so it offers enough space for more extensive cleaning.

The mapping in the app again enables the room division.

The amount of water dripping from the water tank onto the microfibre cloth can also be adjusted in the app. By the automatic room division after the map production, it is possible to predefine when the robot should vacuum or wipe which room – also in which order. No-Go zones (areas that the robot should not travel through) and virtual walls (which only the robot sees and does not drive over) can be drawn on the map and saved as usual.

It is also possible to define a sequence for when which room is to be cleaned.

Outlook: Exciting upgrade?

We are currently testing the new Deebot Ozmo 950 ( review coming soon), which features multiple storey card storage and automatic carpet detection when wiping. These are really exciting technological innovations, but the device also costs around $600. The Mijia Robot STYJ02YM (is this really the final name?) is aimed at a target group with a smaller wallet, who still don’t want to do without a high-end model with lots of functions. Exactly what the Mi Robot 1S already represents.

Black or white: What do you like better about the robot?

But the innovations are – at least on paper – a bit poor. If you want a wipe function, you will be happy, otherwise the model has to go through the test phase to show what has really happened. A suction power of 100 pa more or less is no reason to switch to this model. But if you don’t have a (good) vacuum robot yet, you should keep up to date here – we will update this article as soon as there are any news.

The vacuum robot will be available in China from August 16th, most of the time it won’t take too long until the product makes its way to the China shops known to us and can be ordered. In China, the launch price is 1799 Yuan, or $255. As is well known, the price for us in this country will be a little more expensive again, and it is estimated that the price will go in the direction of $300.

Why doesn't this affect our review in any way?

I'm interested in Gadgets, that make our life at home easier - especially when it comes to cleaning the floor or the windows. I was able to test about fifty robot vacuum cleaners since now.
