Usage Scenarios
Q1: Can the Mijia Wireless Wet Dry Vacuum 5 Pro be used on carpets?
A: The Mijia Wireless Wet Dry Vacuum 5 Pro is compatible with short-pile carpets only. After performing wet cleaning on such carpets, make sure to allow them sufficient time to dry completely. For long-pile carpets or thick plush rugs, we do not recommend using this vacuum, as the cleaning performance may be compromised and the carpets may not dry properly.
Q2: Can the Mijia Wireless Wet Dry Vacuum 5 Pro clean gaps between floorboards or tiles?
A: The roller brush bristle length of the Mijia Wireless Wet Dry Vacuum 5 Pro is approximately 7 mm, so it can effectively clean gaps in flat, hard surfaces such as tiled or wooden floors that are installed smoothly. For uneven or damaged floors, however, the cleaning performance may be reduced. If stubborn stains are trapped in those gaps, running the vacuum back and forth over the area several times can help remove them.
Q3: What is the minimum height of furniture that the Mijia Wireless Wet Dry Vacuum 5 Pro can reach underneath?
A: When the Mijia Wireless Wet Dry Vacuum 5 Pro is laid flat at 180°, its height is 137 mm. We recommend using it under furniture with a clearance of at least 140 mm to avoid any collision. If the foam cleaning module is attached, the height when laid flat increases to 147 mm, so a minimum clearance of 150 mm is recommended to prevent the vacuum from bumping against the furniture.
Q4: What to do if hair gets tangled around the roller brush of the Mijia Wireless Wet Dry Vacuum 5 Pro?
A: Please perform the self-cleaning function promptly after using the Mijia Wireless Wet Dry Vacuum 5 Pro. During the self-cleaning process, the roller brush rotates both forward and backward, allowing the comb teeth at the floor brush intake to dislodge hair and direct it into the dirty water tank.
In cases of severe tangling, remove the roller brush first, use a brush to clear away any hair caught on the comb teeth, clean the roller brush, and then reinstall it in the machine.
Q5: Why does the Mijia Wireless Wet Dry Vacuum 5 Pro leave a water mark after being left stationary?
A: If a water mark appears after the Mijia Wireless Wet Dry Vacuum 5 Pro has been left stationary, please check the following two points.
1. Inspect the sealing ring at the bottom of the clean water tank's water outlet valve to make sure it is properly seated. If the ring has been compressed out of shape, simply reposition it to restore its normal seal.
2. When filling the tank, residual moisture on the bottom of the tank may travel along the outer wall and drip from the bottom outlet. This is a normal occurrence and can be minimized by wiping the bottom of the tank after filling.
Q6: Why does the Mijia Wireless Wet Dry Vacuum 5 Pro feel heavy during use?
A: The Mijia Wireless Wet Dry Vacuum 5 Pro is indeed heavier than previous Xiaomi floor cleaner models. This weight increase comes from the upgraded 4000 mAh soft‑pack battery, which extends the runtime to up to 40 minutes in Water absorption mode. The 26 kPa strong suction also adds to the downward pressure, which enhances cleaning performance on the floor.
To compensate for the added weight, the vacuum is equipped with a central electric assist system that uses a central hub motor to provide flexible and effortless adjustment during operation, making the vacuum feel lighter and easier to maneuver than its actual weight might suggest.
Q7: Is there a risk of burns from the high‑temperature steam of the Mijia Wireless Wet Dry Vacuum 5 Pro?
A: The steam outlet of the Clean water tank is directed straight at the floor, so the steam first comes into contact with the floor surface and the roller brush. A yellow warning label is also placed on the product to remind you of the potential hazard.
Additionally, the steam is not released immediately after you switch to Steam mode; it takes approximately 40 seconds to generate steam before it is released. This delay helps ensure that the steam is only emitted when the vacuum is ready and positioned correctly.
Q8: Why is there airflow from the rear side of the Mijia Wireless Wet Dry Vacuum 5 Pro during operation?
A: The gap below the Dirty water tank of the Mijia Wireless Wet Dry Vacuum 5 Pro serves as the air outlet. During high-speed operation, air circulation through this outlet is a normal phenomenon and does not affect normal use. As for hair and other lightweight debris, they may be blown away by the airflow and temporarily escape suction. In such cases, simply run the vacuum over the area a few more times – this does not affect normal operation.
Q9: What to do if the Mijia Wireless Wet Dry Vacuum 5 Pro is noisy during cleaning?
A: If your Mijia Wireless Wet Dry Vacuum 5 Pro makes noise during use, please check the following cases below to identify the cause:
Reference noise levels for normal operation
The Mijia Wireless Wet Dry Vacuum 5 Pro is equipped with a high-suction motor (26KPa) and integrates steam cleaning and power-assisted water circulation functions. Some operational noise is expected compared to manual cleaning tools. For reference, the maximum noise levels for each mode are as follows:

It is worth noting that the quiet drying performance ranks among the industry's top tier.
Troubleshooting abnormal noises or rattling sounds
If you hear unusual sounds beyond the levels mentioned above, please perform the following checks:
1. Clean the floor brush by disassembling it, removing any tangled hair or debris from the roller, and ensuring that the roller rotates smoothly without obstruction.
2. Next, inspect the air duct and fan assembly. Disassemble these parts and check the fan impeller and volute housing for any blockages or trapped debris. If dirt or tangled materials are found, clean them thoroughly. After cleaning, verify that the impeller rotates freely without scraping and produces no abnormal noise during idle rotation. Finally, reassemble the unit and test it again.
If the issue persists after troubleshooting, please contact the local official after-sales service for further assistance.
Q10: Why does the Mijia Wireless Wet Dry Vacuum 5 Pro leave water stains on the floor during operation?
A: When the Mijia Wireless Wet Dry Vacuum 5 Pro is lifted off the ground while crossing a door threshold, its water‑suction‑and‑discharge cycle continues to operate. In this situation, water is discharged but cannot be sucked back up, resulting in noticeable water stains on the floor. This is a normal operating behavior of the machine and is not a malfunction.
The water‑suction‑and‑discharge cycle runs continuously as part of the regular cleaning process, and the vacuum does not have a suspension detection feature that would automatically stop the water flow. When the suction inlet is lifted off the ground, it cannot create negative pressure against the floor surface, so the suction function cannot take effect. As a result, only the water discharge function continues to run, which leaves water residue behind.

3. If all the above checks are normal and a slight humming sound persists, this is not a fault. The Mijia Wireless Wet Dry Vacuum 5 Pro uses a floating wiper blade technology that maintains constant contact with the brush to scrape away dirt, and the motor rotation naturally creates minor vibration. These may produce a low‑level sound that falls well within the product's cleaning noise specification of ≤74 dBA (Standard mode and Water absorption mode).
Q15: What to do if there are large water stains on the floor after using the Mijia Wireless Wet Dry Vacuum 5 Pro?
A: If the Mijia Wireless Wet Dry Vacuum 5 Pro leaves noticeable water stains after cleaning, the issue usually stems from either roller brush wear or partial blockage in the air duct. The following checks and remedies can help resolve the problem.
1. Roller brush wear or aging
Over time, the brush bristles become shorter, and if the brush is not cleaned promptly after each use, dirt dries on it and makes it stiff, reducing its water absorption efficiency. To fix this, replace the roller brush when it shows signs of wear. Additionally, we recommend running the self‑cleaning cycle and drying the brush after every use, which helps extend its service life.
2. Partial air duct blockage
A blockage in the air duct can weaken suction power, leading to poor water pickup. Several factors may contribute to this: the wiper blade may be contaminated with foreign objects, reducing its ability to squeeze water; the suction inlet or the pipeline may be obstructed; the dirty water tank may not have been emptied, allowing the filter basket to become full; or the filter itself may be clogged. To address this, please empty the dirty water tank and remove any debris from the filter basket. Use the cleaning brush to clear the wiper blade and the suction pipe. Also, wash the filter thoroughly and allow it to air‑dry completely before reinstalling it.
By following these steps, you can restore the vacuum's water‑pickup performance and reduce water stain residue on the floor.
Q16: Why is the battery runtime of the Mijia Wireless Wet Dry Vacuum 5 Pro short?
A: The battery runtime of the Mijia Wireless Wet Dry Vacuum 5 Pro varies depending on the operating mode selected.
1. In Steam mode, the vacuum runs for at least 15 minutes on a full charge.
