You are looking to buy a robot vacuum cleaner (automatic vacuum cleaner) but do not know how to choose to suit your living space. Please refer to our article below to choose the most suitable automatic vacuum cleaner.
Choose by home space
Robot vacuum cleaner for street houses

Street-front houses are often exposed to many types of dust and impurities that sometimes cannot be completely cleaned with a broom. In this case, you should choose a robot vacuum cleaner , which has both vacuuming and mopping functions.
A robot vacuum cleaner with 3 layers of HEPA filter will make your home air cleaner after vacuuming. The robot's suction power only needs to be 800pa or more to be stable.
Robot vacuum cleaner for low-rise apartments and houses in alleys

This space is less affected by dust than street-front houses, but the need to dry the floor will be higher because the air is not as well-ventilated as street-front houses.
For these types of houses, you should choose robot models with integrated Anti-Dropping water-based mopping feature that helps the robot to drop water to mop the floor without wetting the floor too much, leaving only a thin layer of water on the floor, drying quickly and not damaging the floor. The robot's capacity is about 1000pa to meet the needs of use.

High-rise apartments and villas have a lot of thin dust in the air that flies into the room. Moreover, these spaces often use carpets, so dust will accumulate more easily.
Therefore, a high-end robot vacuum cleaner will be most suitable for this space. They have the ability to recognize carpet floors to switch the vacuuming mode from hard floors to carpets and vice versa.
In addition, high-end robot vacuum cleaners with a specialized mopping mode for carpet floors have a vacuuming function and very strong sensors, ensuring that dust is completely removed. You should choose a vacuum cleaner with a large capacity, about 2000pa or more, to be able to vacuum and clean the house.
