*10 seconds: During testing, the dust collection time was measured at 10 seconds using a stopwatch with a precision of 0.01s.

*75 days without the need for dust emptying: During testing, the duration was equal to or greater than 75 days under the conditions that the robot vacuumed the carpeted floor of a 100m² house accommodating a family of two people, returned to the base every day, and the volume of the dust bag was measured once every 4 days.

*4L super-large-capacity water tank: During testing, the volume of the water tank was 4L on the condition that the water tank was first filled with clean water and then fully discharged and measured on an electronic scale.

*Mopping for up to 280m²: Based on Xiaomi Internal Labs testing environment, the cleaning area was equal to or greater than 280m² (the mopping area and the construction area were equal to or greater than 500m²) in the standard mode on the condition that the robot was fully charged, the water tank on the base was filled with water, and the test was performed in the "Daily cleaning" mode and with a 10 ㎡ mop pad cleaning frequency. The mopping area may vary due to differences in the home environment and habits of use. It is subject to the actual dimensions.

*6000Pa powerful suction: When the vacuum degree was measured at the suction inlet using a vacuum degree tester, the maximum power reached was 6000Pa on the condition that the vacuum was fully charged with a measurement range of 0–20kPa and a precision of 0.01Pa.

*180rpm: The rotational speed was measured at 180rpm during testing using an infrared tachometer on the condition that the vacuum had been continuously running for 3 minutes and was then stabilised.

*Millimetre-level sensor precision: In tests, industrial grade reflectors of various reflectivity were placed on high-precision moving rails with a sliding rail movement accuracy of 0.05mm and a range of 0–500mm. Starting at the centreline of the product bumping plate (0cm), line laser measurement precision at different distances in 50mm movements resulted in millimetre-level precision with a deviation of ± 5mm within 500mm. Detectable obstacles depend on environmental conditions and usage scenarios. Obstacle identification and avoidance effectiveness will depend on the actual usage scenario.
