Robot vacuum cleaners are increasingly popular in Vietnam, especially when their prices are getting cheaper and cheaper. Currently, if you accept to buy laptops, you can find many products from big and small brands for only about 3 – 4 million VND. In the higher segment, it is not uncommon for models costing about 7-12 million dong with more genuine features, and the most “top” have smart super-classes, full of cool features with prices around 20 million or more.
Cheap robot vacuum cleaner only 3-4 million worth buying? If you buy, what do you gain and lose?
So, spending tens of millions more, what more do we get? Is it enough to buy all kinds of 3-4 million? Let’s find the answer together.
What are the weaknesses of cheap robot vacuum cleaners?
By default, as long as the robot vacuums it, it must be … vacuumed first. These models all have the same mechanism as moving wheels, object recognition sensors, suction mouth and dust collection brush. Inside, there is a sophisticated mechanical system to automatically run around the house to clean, wherever the robot can sneak in, it can vacuum. Many cheap types today also have integrated mopping systems with removable water containers and rags.
Cheap robot vacuums do not have enough sensors to detect small objects, so it is easy to get stuck.
The biggest difference of cheap robot vacuums is the less sophisticated sensor system. It is true that it can map the room, identify obstacles and dodge, but the efficiency is very low, the risk of getting stuck, sucking electrical wires, and items on the floor is still extremely high. These types often work by crashing into furniture, finding it impossible to walk, then changing direction and drawing boundaries for the electronic map.
The vacuuming ability of the current cheap robot is not too bad, most of them reach 1000 – 2000Pa, just enough to handle small garbage and dirt on hard floors. Houses who use more thick carpets will find it “intrusive” because it must have a stronger suction to be able to clean.
Some lines have suction power that is not strong enough to handle large garbage.
Some cheap robot lines do not have a “hump” on their back (which is LiDAR 3D scanning sensor technology like on new iPhone models). Instead, it is just a regular camera facing the ceiling, so the ability to recognize the location in the evening is extremely poor, it is imperative to turn on the lights to make the device work more effectively otherwise it is easy to get lost and not return. charging dock.
What’s better than a high-end robot vacuum cleaner?
Of course, the premium price double, triple, the experience must be different. They will have a better sensor system, faster and more accurate location recognition, furniture. Some types do not even touch the edge of the wall or the foot of the known table and chair but dodge. All thanks to the “hunchback” on the back with a fast object scanning speed, detailed 3D mapping to every electrical wire lying on the floor. Therefore, the robot will avoid getting stuck, damaged or straying around.
The “hump” on the robot vacuum cleaner’s back turned out to be very useful, helping the robot identify objects and locations more accurately, faster, limit entanglement and be able to operate completely normally in a dark room.
The more expensive types will also have stronger suction capacity, up to 3000 – 4000Pa, enough to suck large garbage, suck thick carpet… Their batteries also have a longer life per charge, suitable for use for high-class apartments, large floor, suction from the bedroom to the living room and kitchen… The large battery also helps the robot to limit the problem of going too far, not having enough power to return to the charging dock and “oversleep” somewhere. waiting for you to “rescue”.
In the 10 million segment, you can also find robots with built-in charging docks to clean up trash. So you won’t have to manually remove the dust box every day to empty the trash. Instead, it takes a month to remove the large dust bag in the dock and throw it away once.
About 10 million to buy a robot vacuum cleaner, remember to choose a type with a charging dock to clean up trash for “fun”.
Even more advanced, there are specialized cleaning robots with rotating and vibrating rags to remove stains on the floor.
Both low-cost and high-end robot vacuums now often integrate the ability to wipe with water. However, many high-end lines are also made for more professional cleaning. They are heavier, the mop rotates 360 degrees or vibrates to increase cleaning ability. Some are also equipped with a charging dock that automatically cleans the mop after each use. “Miraculous” is that so the price of this dish is also quite high, possibly up to 15-20 million VND or more.
So which one should I buy?
In general, buying any kind of robot will also make your floor cleaner, but depending on your needs and wallet, you should choose the right one to avoid regretting buying the wrong one.
There are good enough robot vacuum cleaners in any price range, but if you buy a cheap one under 5 million, you will have to sacrifice a lot of useful features.
If the house has a lot of cluttered furniture, many nooks and crannies that the robot can get into, choose models with 3D LiDAR scanning sensors to limit entanglement. If you have a large floor, you must choose a durable battery that can last a few hours on a single charge. If you want to be really clean, you should invest in a specialized type for cleaning, and if you want to have more free time every day, you should definitely invest in a charger with a self-cleaning charging dock.
