Cleaning Modes
The SUNSMAI B75-2-Pro offers two cleaning modes:
- Steam Mop Mode: For deep cleaning and dissolving stubborn stains. The mop head releases steam while the roller brush cleans.
- Dry-Sweep Mode: For quick pickup of dry debris. The roller brush operates without steam.
Switch between modes using the controls on the handle. The LED lights on the mop head assist in illuminating dark areas during cleaning.

Maintenance
Self-Cleaning Cycle

Emptying and Cleaning the Dirty Water Tank
The dirty water tank should be emptied and cleaned after each use to prevent odors and maintain hygiene. The tank can be easily removed for direct cleaning.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Red light is on/flashing |
|
|
| No steam |
|
|
| Won't power on |
|
|
| Can I add detergent? | Not recommended. | Do not add any detergents or chemicals to the water tank. Use only water for steam cleaning. |
| Is this a vacuum? | It's a 3-in-1 cleaner that steams, sweeps, and mops. | A rotating roller lifts and collects debris while the surface is cleaned. It does not use vacuum suction, so it runs very quietly. |
| Tank size and runtime? | 450 ml clean-water tank. | The 450 ml clean-water tank lasts about 20 minutes in steam mode and is easy to refill. |
Note: Due to differences in production batches, the water tank cleaning brush may be missing. If not included, contact customer service for a free replacement. This does not affect normal use.
