- Whether the cleaning is dry or not depends mainly on the suction and clean standard accessories:
Make a point in advance: Choose a higher suction power, and it will be cleaner when cleaning the carpet, and a Robot vacuum cleaner with a decibel below 70 is better.
Check the needs of single and bilateral brushes, choose more than one side for the carpet, and choose both sides if you want to be cleaner.
Use a roller brush for more dust; choose a rubber brush or a single suction port for pets with more hair on the ground.
The sweeping robot is a double combination of “sweeping” + “suction” to gather and store garbage.
- “Suction”: Choose the suction you need:
In general, of course, the greater the suction, the better the ability to vacuum.
Now don’t worry too much about the louder the suction, the louder the noise, because the robot vacuum cleaner is very smart now and won’t let its suction exceed 80 decibels.
There are some high-suction intelligent machines that can automatically adjust the suction by judging the actual situation on the ground.
- “Sweep”: the preferred combination of cleaning tools:
The number of side brushes and the type of suction port determine the cleaning degree of the robot vacuum cleaner.
The “sweeping” of the sweeping robot relies on the side brush next to the suction port to take out the garbage in the dead corner. Its corner cleaning ability is an important reference factor for purchase.
Two side brushes – can cover the sweeping area as large as possible, which is equivalent to sweeping twice.
The roller brush in the middle – similar to the electric suction head of a vacuum cleaner, can stir out the dust in the gap of the floor and clean more thoroughly.
- Can you avoid ground obstacles:
Just look at the “intelligence” level of the sweeping robot
Although the sweeping robot has double “eyes” to see the direction, the difference between different navigation modes is the difference between mental retardation and intelligence.
This involves the core function of the sweeping robot: path planning + obstacle avoidance ability, which depends on him: navigation system + obstacle avoidance system
- Navigation system
This is a function that plays a decisive role in the intelligence level of the sweeping robot.
After all, the ground conditions are somewhat complicated. Basically, the sweeping robot uses the navigation system to work together with the navigation sensor to map or model the indoor area, and then use the algorithm to plan the cleaning route.
Laser navigation is divided into LDS laser navigation and dTof laser navigation, which detect the surrounding environment by emitting laser light, and complete the model establishment of the entire space during the mobile operation.
LDS+SLAM algorithm, lidar 360-degree detection, automatic update of cleaning map. ddToF laser mapping 3.0, the accuracy is improved by 20%. A raised scanner rotates and emits laser light at high speed, and the distance of the object is judged by the time when the obstacle is reflected back, so as to determine the position and realize the positioning. Laser navigation modeling is more accurate than visual navigation, and path planning is more reasonable. Because the technology is mature, it is usually more cost-effective and is a suitable choice for most families.
- The obstacle avoidance system determines the flexibility of the machine
Obstacle crossing ability is generally determined by the combination of drive system and sensor. It needs to be used whether it is stepping over the sealing strips under the doors of various rooms, or climbing some thin carpets to clean. The height at which the obstacle can be crossed is usually as large as possible.
- Battery life + recharge capability, this is a must for smart home
The larger the cleaning area, the larger the capacity of the lithium battery is.
In addition, the automatic recharging function of the sweeping robot is a must. Even if half of the scan runs out of power, it can automatically return to the charging compartment for charging, and you don’t have to find him for manual charging if you don’t need to scan halfway. This is a smart product! Some sweeping robots also support continuous sweeping at breakpoints. After recharging, return to the area where the cleaning was interrupted and continue to complete the cleaning task.
- Dust box capacity
He is the “belly” of the sweeping robot that eats garbage. Once the capacity is small, it may stop halfway through cleaning, which requires us to continuously dump the garbage, which takes time and effort to clean up.
Now the dust box capacity of the sweeping robot is generally about 0.3ml. If the paddle is cleaned every day, there is a good chance it will need to be dumped in less than a day. Therefore, it is best to choose a capacity of 0.5ml or more.
