Comparison Xiaomi MiJia 1C vs Roborock S5

A function that allows you to adjust the amount of liquid supplied to the robot vacuum cleaner’s pad, mops, or cleaning roller. A low level is suitable for laminate and parquet flooring, while a more intensive level is ideal for tiles and areas with noticeable dirt. Water flow adjustment helps prevent excessive floor wetting while improving wet cleaning efficiency.

Measured in Pa, this indicator describes the robot vacuum cleaner's suction pressure: the higher it is, the easier it is for the device to pick up heavy debris and clean carpet pile. Values around 2,000–4,000 Pa are usually sufficient for regular cleaning of smooth floors, while 6,000–10,000 Pa and above are better suited for collecting hair, sand, and dirt from carpets or floor joints.

The dustbin capacity indicates how much dry debris fits in the robot vacuum’s built-in container before it needs to be emptied. Models with a 200–300 ml capacity are suitable for a small apartment and frequent cleaning cycles, while a 400–600 ml capacity is more convenient for larger areas, pets, or lots of hair. For robots with a self-emptying station, the size of the internal container is less important, as debris is automatically transferred to the docking station’s collection bin.

The tank capacity determines the water supply for moistening the pad, rotating mops, or cleaning roller. Compact tanks of around 200 ml are suitable for regular wiping of small areas, while 300–500 ml tanks allow fewer interruptions for refilling during cleaning.

Fine filter captures fine dust, pollen, and other particles that have passed through the main dust container, preventing them from returning to the room air. The higher the class, the more effective the filtration.

— EPA 10. Retains at least 85% of particles of the most penetrating size and provides basic fine filtration of the outgoing air.

— EPA 11. Captures at least 95% of fine particles, making it better suited for regular cleaning of dusty rooms.

— EPA 12. Provides efficiency from 99.5% and noticeably reduces the amount of fine dust returned to the room.

— HEPA 13. Captures at least 99.95% of the most difficult-to-retain particles and is especially useful in homes with allergy sufferers, children, or pets.

— HEPA 14. Retains from 99.995% of such particles and provides the highest level of filtration among the listed classes.

Map building allows the robot vacuum to remember the layout of the room, track covered areas, and plan a consistent cleaning route. The method used to create the map affects its accuracy, orientation speed, and the device’s ability to detect obstacles.

— With sensors. The robot creates an approximate map based on data from the gyroscope, motion sensors, wheels, and collisions with obstacles. This system is more affordable, but determines the exact position of walls and furniture less accurately, and accumulated errors may lead to repeated passes or missed areas.

— With a rangefinder. A laser rangefinder, or LiDAR, measures the distance to surrounding objects and creates an accurate map of the room before completing a full pass around it. It works reliably in low light, confidently detects walls and furniture, and supports room division and no-go zones.

— With a camera. The camera analyzes the surroundings and navigates using visual objects, helping refine the robot’s position and the room layout. Its advantage is the ability to distinguish individual objects, although performance depends more heavily on lighting.

— With a rangefinder and camera. The combined system uses LiDAR for accurate distance measurement and map building, and a camera to detect small objects on the floor. Such a robot not only navigates rooms confidently in any lighting, but also avoids cable...s, shoes, toys, and pet bowls more effectively.

Multiple map memory allows the robot vacuum to save separate layouts for different floors or rooms. When the device is moved, it recognizes the required map and uses the already defined rooms, no-go zones, and cleaning settings. This feature is especially useful for multi-story homes, as it eliminates the need to rescan the space every time the robot is moved.

Battery capacity indicates the amount of charge available to the robot vacuum for navigation, motor operation, brushes, and the mopping system. A higher-capacity battery can potentially provide longer runtime, but it does not allow the exact cleaning time to be determined without considering the device's power consumption. Operating time is more strongly affected by the selected mode, suction power, floor type, use of mopping pads, and frequency of returns to the docking station.

Battery life determines how much area the robot vacuum can clean before returning to the docking station. Actual performance depends on the selected mode, suction power, floor type, operation of the mops or roller, and layout complexity. Therefore, the stated maximum time is usually achieved in a gentle mode and will be noticeably shorter during intensive cleaning.
