Robot vacuum cleaners have become an essential cleaning tool in modern households, loved for their convenience and efficiency. With continuous technological advancements, the competition in the 2025 robot vacuum cleaner market has become even more intense, with major brands launching products with diverse functionalities.

This article provides a comprehensive guide on how to choose a robot vacuum cleaner that suits your needs and offers a multi-angle comparison of popular models on the market, giving you the most professional purchasing advice.

Robot Vacuum Cleaner Introduction

Most robot vacuum cleaners have a round, disc-shaped body with wheels at the bottom for movement. These devices integrate sweeping and automated functions that can automatically clean the floor. Users can start the robot vacuum cleaner with the push of a button or through a mobile app, allowing it to navigate the room, pick up dust and debris, and reach difficult-to-clean areas such as under sofas and beds.

Robot vacuum cleaners are particularly suitable for the following groups:

•    Busy urban professionals
Save time on household chores, allowing working individuals to focus more on work and leisure.

•    Households with pets
Effectively pick up pet hair and scattered food debris.

•    Elderly and individuals with mobility issues
Automate cleaning tasks, reducing the need for bending or manual sweeping.

Robot vacuum cleaners not only enhance cleaning efficiency, but also provide a smart home experience, making them a perfect blend of technology and practicality.

Key Points for Choosing a Robot Vacuum Cleaner

1. Height of Robot Vacuum Cleaner

The height of a typical robot vacuum cleaner is around 10cm. Before purchasing a robot vacuum cleaner, customers should consider the distance between their furniture and the floor, especially in narrow spaces such as under sofas and beds. If there is low-clearance furniture at home, customers may opt for a slimmer model with a height of less than 10cm, ensuring enough space for robot vacuum cleaner to pass under low furniture and clean hard-to-reach areas.

2. Suction Power and Cleaning Performance

Higher power means stronger suction, which is better for deep cleaning. Some vacuum cleaners feature high-efficiency suction, multi-layer filtration, and sterilization functions. They can effectively remove dust and dirt, keeping floors clean and hygienic. If you are concerned about hair tangling in the brush, you can choose a rubber roller design and clean it regularly.

3. Obstacle Avoidance and Navigation Technology

Obstacle avoidance and navigation can directly impact cleaning efficiency. Robot vacuum cleaners generally follow either "random" or "planned" path navigation.

	Random Collision	LiDAR Navigation	Camera Navigation	Gyroscope Navigation
Type	random	planned	planned	planned
Operation Method	move randomly and change direction when hitting an obstacle	uses LiDAR to scan the environment, distinguish objects, create a map, and plan cleaning routes accordingly	use built-in cameras to capture images of the room and recognize obstacles	use an internal gyroscope to measure and directly record motion routes
Features	suitable for small spaces easily re-cleans areas or misses spots, resulting in lower cleaning efficiency	high positioning accuracy, suitable for complex room layouts	recognize ground obstacles and record room structures, suitable for multi-story homes	more systematic than random collision type, suitable for medium-sized homes limited positioning accuracy

Some robot vacuum cleaners include collision sensors on the sides, which allow them to adjust their direction upon impact. Advanced features like anti-drop and climbing sensors can help robot vacuum cleaners navigate over obstacles and avoid falling from heights.

4. Battery Life

The longer the battery life of a robot vacuum cleaner, the fewer times it needs to return to the charging dock, allowing it to clean a larger area. Robot vacuum cleaner with a battery life of 30–60 minutes can meet the needs of a small household. For larger homes, vacuum cleaner with a battery life of 90 minutes or more is recommended.

5. Floor Type Compatibility

• Wood floor: recommend choosing a model with gentle suction to prevent scratches
• Tile floor: recommend choosing a high-suction model to remove fine dust from gaps
• Carpet: recommend choosing a model with strong suction and fiber-cleaning capabilities

6. Charging Dock Features

Some robot vacuum cleaners come with charging docks that offer additional functions:

•    Automatic mop cleaning

The dock contains clean and dirty water tanks. Robot vacuum cleaner can dampen its mop before cleaning, and the dock will automatically wash the dirty mop after cleaning.

•    Hot water mop drying

Use hot air or hot water to clean and dry the mop, preventing bacteria buildup.

•    Auto-sterilization

Release silver ions or add cleaning solutions to eliminate bacteria from the mop.

•    Automatic dust collection

The dock collects dust and debris from the vacuum cleaner, reducing the need for frequent emptying.

7. Noise Level

If you have pets or babies, choose a robot vacuum cleaner with noise levels below 60dB.

8. Additional Features

In addition to vacuuming and sweeping, some robot vacuum cleaners contain HEPA filters, mopping functions, and even smartphone app control. Mobile app control allows users to schedule cleaning time and target specific areas, enhancing the overall user experience. Some vacuum cleaners also feature an automatic mop-lifting function, which raises the dirty mop after cleaning to avoid touching the carpets or floor, preventing secondary contamination.

Robot Vacuum Cleaner Usage and Maintenance Tips

1. Prepare Cleaning Environment

Before using the robot vacuum cleaner, ensure that obstacles on the floor will not prevent it from cleaning or returning to the charging dock. Fragile items such as water cups and vases should be put away to prevent the robot vacuum cleaner from knocking them over during cleaning. The fringes of carpet edges should also be folded up.

2. Proper Placement of Charging Dock

The charging dock should be placed against a wall on a flat surface, with sufficient space in front and on both sides to allow the robot vacuum cleaner to return smoothly after cleaning. The charging dock's power cord should also be properly organized to prevent tripping hazards for household members.

3. Usage Limitations

Most robot vacuum cleaners are not suitable for cleaning wet or slippery floors, so users should avoid letting moisture seep into the device. Additionally, robot vacuum cleaners are generally designed for smooth surfaces, so they should not be placed near door thresholds or stair edges to minimize the risk of malfunction.

4. Regular Maintenance of Robot Vacuum Cleaner

The dustbin capacity of most robot vacuum cleaners is relatively small. It should be emptied immediately after each cleaning session, in order to prevent dust buildup and avoid affecting future cleaning efficiency. The body, sensors, filters, side brushes, and rolling brushes of the robot vacuum cleaners tend to accumulate hair and debris, so they should be cleaned as needed. Users should also regularly clean or replace the filters, especially the HEPA filters, which helps maintain vacuum suction efficiency to improve indoor air quality.

Some robot vacuum cleaner components are washable, but they must be completely dry before reassembly. For those with a mopping function, the water tank should be cleaned after each use in order to prevent scale buildup and bacterial growth. If cleaning agents are used, ensure they are safe for the vacuum cleaner’s water tank.

5. Keep Software Updated

Users can check and install the latest software updates for their robot vacuum cleaners through a mobile app to access new features and performance improvements.
