Summary

The MinSu NV - 01 is a surprisingly good robot vacuum cleaner. I wasn't expecting it to clean so good. For about $170 you get an amazingly-looking machine that has a metal lid, vivid display, and strong suction. It performs great with a suction inlet and main cleaning brush. Compatibility with Alexa enabled devices allows controlling the robot with voice. There are two ways to manage the cleaner: through the app and remote controller. With purposeful navigation, the MinSu covers all cleaning area making it work more efficiently than the robots with random cleaning pattern.

Robot vacuum market is growing fast, more and more people want to automate their house and daily routine. Robot vacuums help to save time and effort that you spend on cleaning your house, and they become more and more accessible. For a price under $200, you can buy a very decent robot vacuum. A few years ago, such a machine would cost you at least twice as much. Budget robot vacuum cleaners become smarter and now they have strong suction, can build a map of your house, can be controlled by voice and much more. Today we want to talk about one of those intelligent devices, the MinSu NV - 01, a budget robot vacuum that has impressive features, and can beat even more expensive competitors.

MinSu NV - 01 appearance

Design and first impression

Most of the robot vacuums have a round shaped or D-shaped body, the MinSu NV - 01 instead has a square-shaped design with rounded corners. The material and overall quality seem good to me, and I like it's beautiful black & white minimalist design. On the top, it has a few buttons: start/stop button, return to the charging dock, and wet mopping mode. Here is also an LCD screen where you can see current time, current mode, etc. The touchscreen is sensitive when I run my fingers over it, the display responds right away.

When I open the top lid, I see a dustbin that holds about 500 ml of dust. The lid is made of chromium metal that is very nice to touch.

There is no bumper that we usually see in other robots. A bumper protects furniture from scratching when a robot bumps into it. The MinSu is equipped with anti-collision sensors and ultrasonic detectors that supposed to be more sensitive and prevent bumping.

There are two large wheels underneath that are able to climb an obstacle up to 15 mm. Two side brushes work together agitating dust and dirt from corners and transfer it to the main brush (or suction inlet) where 1,500 Pa suction sucks it inside the dustbin.

What we noticed when tested the robot: when the inlet is on, the suction power becomes stronger and sucks good, if you insert the main cleaning brush, it will absorb dust from carpet.

Suction inlet without main brush

Both the cleaning brush and suction inlet work good on thin carpet, the suction inlet is tangle-free, and I haven't had any issues with wrapped hair.

If you insert the water container, the MinSu would be wet mopping bare floor. The 100 ml water tank controls water dripping.

Unlike other robot vacuums in this price range, the MinSu NV-01 never missed any areas in my apartment. How can this affordable machine be so smart? The secret is in an internal ARM processor; it makes the robot smarter than all those robot vacuums with a random cleaning pattern. The robot has a bunch of sensors such as gyroscope, ultrasound, and infrared sensors that detect the robot location in real-time and along with the simultaneous localization and mapping algorithms (SLAM), build a map and calculate the most efficient path to clean your entire house. Why is this feature so important? Thanks to this technology, the robot moves in parallel lines (Z-pattern), cover the whole area without missing spaces and repetitive cleaning.

Other budget robot vacuums that we have tested just randomly move across the house, they can miss some areas and clean a few times in other places that are already cleaned, sometimes they can't find the charging dock, especially in a big house, since they don't remember where it is placed. So I like that this model has the mapping feature, it takes less time to cover the whole area, and the robot can easily compete with more expensive models. Thanks to this, it covers 99% of the house area. I tested the robot a few times in hard to reach places, between the chair legs on the kitchen, it had been maneuvering seamlessly.

It is worth mention that the gyroscope navigation is technology that was made for budget robot vacuums. It has its disadvantages compared to flagship robot vacuums with a laser (LIDAR) and camera system. For example, there is no possibility of setting digital virtual walls, blocked areas, and you can't specify some area on the map to be cleaned. The map created by gyroscope is mostly shown where the robot has cleaned, you cannot interact with it.

First cleaning test

We tested this robot vacuum on bare floors and carpets and surprisingly it had shown great performance! A powerful motor provides strong suction, thanks to this it sucks all the dust and hair hidden in the carpet. Although the robot has strong suction delivering 1,500 Pa, it works relatively quiet. Even though the MinSu has significantly weaker suction that upright vacuums have, it is still decent power in the world of robotic vacuum cleaners. Even some flagship robot vacuums have a weaker suction than this little guy.

I have a door threshold that this robot climbs without any problems. A synthetic test showed that the MinSu NV-01 could climb a plank up to 0.78 inches (1.5 cm) height. Unfortunately, I don't have a high-pile carpet to test how it can climb on it, but it worked decently on my medium pile carpet.

How to control the robot vacuum

There are a few ways how you can control the robot. The first one is a smartphone app. The app looks polished; it's easy to connect the robot and use it. You can see how the robot builds a layout of your house in real-time which is a great feature for such a budget robot vacuum. There is a fantastic feature in the app: it supports voice control via Amazon Alexa. However, I have not had the opportunity to test how it works.

It has an IR remote controller which looks absolutely the same as this one from the VIOMI VXRS01 that we reviewed recently. The remote controller allows you to change modes, manually control the robot like a radio car, schedule it for automatic daily cleaning at the specified time, start/stop/pause, etc.

How the MinSu NV-01 avoids collisions with furniture

In my opinion, the ultrasonic detectors work about the same when it comes to avoiding bumping as cliff sensor do. The robot has issues with recognizing dark shades furniture and bumps a little bit harsher than with other obstacles. The sensors keep the robot from getting close to walls, furniture, etc. It causes worse cleaning on corners and along the walls. The robot doesn't get too close to the walls and leave these zones untouched.

However, the robot's sensors work great and do not allow it to damage furniture. They recognize big obstacles preventing bumping.

What I'd like the MinSu to do

Unfortunately, there is no chance to create digital virtual walls with gyroscope-based mapping technology. Reasonably to notice, the robots with a camera sensor are either not allowed to do it.

Continuous cleaning would be great. Once the battery recharges, the robot would resume cleaning from the place it left off. With the MinSu, you need to restart it manually when it's done charging.

For the price of $170, I have no complaints about cleaning quality; the robot performs as good as expensive vacuums do on thin carpets and bare floors.

What we get for the price?

  • long battery life
  • purposeful cleaning pattern
  • amazing design
  • can sweep and mop
  • has a cleaning brush and suction inlet
  • works with Alexa enabled devices
  • has a low price tag

If your home is covered with a bare floor and some carpets, the MinSu NV - 01 is a perfect budget robot cleaner that is smart and doesn't miss a spot when cleaning. Suitable for pet hair. Please note, that the MinSu is bot suitable for thick carpets and rugs.

There are a few alternatives for the price only. You most likely would not find such an excellent robot vacuum cleaner for the price of $170 that have mapping, knows where it has cleaned and would look so good.
