Samsung vs. Lefant, Pros & Cons

In the world of consumer electronic devices, Samsung sticks out. They are one of the leaders in the world of smartphones and also LED displays. However they additionally manufacturer refrigerators, ac units, dyers, and of course, even robotic vacuums.

The PowerBot R9040 is their mid-level version that costs $550. For Alexa owners, this is an excellent option due to the fact that it is certified to be compatible with it. It’s also one of the reasons why I bought it. However, is this product better than its rivals like the Lefant? Let’s find out.

Samsung asserts this to have 10x even more power than the “leading robotic vacuum cleaner brand”

Wi-fi connection

Visionary mapping as well as complete sight sensor aids in draws up an optimal path as well as prevent barriers

Cyclonic purification does a great task keep the filter clean longer


Very expensive

Navigation isn’t as advanced as its rivals – Roomba, Xiaomi, Lefant, and Dyson

Will just run until the battery is low

Very tall – over 5″

Poor performance for carpet

What to get from this Alexa-compatible robot vacuum?

When I first saw this vacuum, it was massive. Larger than any robot I’ve ever evaluated. It’s taller than the Jisiwei and broader than a Xiaomi, and is much larger sized than Lefant series.

This is both excellent and bad. Excellent because the wide cleaning path indicates it’ll cover a lot more area. Bad due to it won’t fit in tight areas and absolutely will not go under a great deal of furniture like Lefant M201 or M213.


In the middle of the robot, you’ll find the electric motor as well as a dust bin. It is a big reason why this robot is so huge. The dirt compartment is one of the biggest in the market and will hold a great amount of dirt. It easily dwarfs other brands of dustbins. Lefant most models have just 500mL capacity, which means users need to empty the dustbin frequently, even in the middle of the cleaning cycle.

Inside it is a whirlwind filter that maintains fine dirt far from the filter on the side. The filter itself is washable but Samsung did not specify if this is a HEPA filter or not. Lefant comes with HEPA filter for capture fine particles and pollen, which is better for allergies.

It also has an all-LED user interface with 3 buttons at the button. Considering that it uses brilliant LED, it is clear and also it shows all the details about the robotic from battery condition, WiFi to the mistake code. For error codes, you’ll need to refer to the handbook to see what went wrong and how to address it.

To see how big this robot is, you need to turn it over. It requires 6 wheels to support its substantial frame. An additional thing I discovered is that the lack of a side brush obstructs it somewhat when cleaning the corners. Lefant M201 has just one side brush, but its size is small enough to slide under most furniture.

Poor Edge Cleaning

In a number of cleaning tests I’ve done, it did not clean the edges along with the Lefant robots I’ve examined.

If you check out the sides of the motorized brush, there is space– an inch left-wing and half an inch on the right. This indicates that it will miss areas at the edge completely. This is a big reason why Neato had to add a side brush in their BotVac series despite having a beater bar really near to the edge.

However, it has a vast motorized brush that measures 12.24 inches. It’s almost as wide as the Neato’s brush. The wide brush does aid it to cover more ground with fewer passes.


Samsung states that this robotic has the “Visionary FullView Sensor” that creates an optimum cleaning path.

Initially glance you would certainly believe it has similar navigation as the Roomba 980– foreseeable back and forth pattern. It’s most definitely a renovation over the Roomba 800 as well as 700 series. However it lacks the SLAM formula so it lacks intelligence as well as simply run until battery runs low.

Although the Lefant robots almost run randomly, with the upgraded 6D built-in anti-collision infrared sensors, it can help detect probable stuck areas and adjust the cleaning path automatically, which makes cleaning more efficient.

WiFi and Smartphone App

This is one of the robot cleaners nowadays that has WiFi connectivity and a smartphone app. Connecting the app and robot is a relatively direct procedure.

Look for the “Samsung Smart Home” app. The following step would be signing up for a cost-free account then logging in.

Make note that you can make use of the Samsung application in numerous other Samsung tools not simply this robotic so if you’re a faithful client this is a huge plus.

After logging in search for “robot vacuum” in the list and have the remote ready to make the virtual connection. When the app finds the robot, it’s time to connect to your home’s WiFi network, input the password as well as the rest is self-explanatory.

Finally, you can’t utilize the app without the router.

In regards to attributes, the app is rather bare. It enables you to start/stop the robotic, schedule and inspect the battery state. That’s regarding it. It will not reveal the area of the robot or if the container is complete. So does Lefant. One of the things that Samsung does not have, but Lefant Lift app does is to change the cleaning mode and check the status of the cleaning activity in real-time. From a brand name like Samsung known for electronics, this is a disappointment, to be honest.

Cleaning Performance

Bare floor

Now I’ve just evaluated this robotic on bare floor and performance was decent yet not great. The lack of a side brush does hurt it a bit when cleaning corners because there are gaps in both sides.

It was able to clean around 45 out of the 50 grams of dust I spread on the flooring if you’ve seen in the initial cleaning test I did. Subsequent tests yielded nearly the same results, given or obtained a few grams.

One thing I noticed is that it has a slight tendency to plow soil because it has two wheels in front of the motorized brush. But it will only be a problem for you to clean up large pieces of dirt like this.

After running the robot for nearly an hour, it did quite well. One of the biggest difficulties of this robot is cleaning corners and edges because it doesn’t have any side brushes. This should not be a problem for daily cleaning.


Regrettably, I did not have enough time to evaluate this device on carpeting yet based upon the reviews I’ve read, it will have a hard time cleaning fine powder on the rug.

The other issue would certainly be not to go across the black rug. This robotic will not pass over those areas if your home has rugs that are black or parts of it are black.

That’s due to the cliff sensing units. If it sees anything black, it will certainly stop, back-up as well as go in other directions.

Machine isnt as good as I hope

The machine lacks side brushes and is so huge in size, along with a basic app. However, it sold at a higher price. In comparison to Lefant, Lefant has a much better app and just $149.9 cheaper.

At $500, it’s hard to recommend this robot with other cheaper options available like Xiaomi and Lefant. If you don’t mind breaking your bank, I’d go with the Roomba 900 series that’s $200 more or the BotVac D5 for around the same price.
