Comparison Dreame F20 vs Mova E20s Pro

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.

A function that automatically adjusts suction power based on the type of surface or the amount of detected debris. On carpets or heavily soiled areas, the robot increases power, while on smooth floors it reduces it to save battery life and reduce noise. Automatic power adjustment helps maintain cleaning quality without constantly selecting the mode manually.

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.

Cleaning area restriction lets you prevent the robot vacuum from entering certain rooms or selected floor areas. This is useful near pet bowls, fragile items, wires, children’s play areas, or surfaces that should not be wiped with a wet attachment. There are various methods.

— Laser sensor. A separate accessory that creates an invisible boundary — the robot detects it with its sensors and does not cross it. It can be moved between rooms, but the device takes up floor space and usually requires separate power.

— Magnetic tape. A strip is placed on the floor or under a thin covering, creating a physically defined no-go line. This is a simple and reliable method, but the tape may be noticeable in the interior and only restricts the area where it is laid.

— Mobile app. No-go zones and virtual walls are applied directly to the saved map of the room. This option does not require additional accessories, allows you to quickly change boundaries, and is usually the most convenient for regular use.

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.

Full charging cycle of the robot vacuum to restore the battery from the minimum level to 100%. The process usually takes several hours and depends on the battery capacity and charging system power. However, with regular returns to the base, this parameter rarely affects cleaning convenience.
