Dreame Robot vacuum cleaner with mop

How effective is the mopping function compared to manual mopping?

The mopping function works best as maintenance cleaning rather than deep scrubbing. It uses a damp cloth approach with controllable water flow through the app. The 270ml water tank provides light moisture for dust removal and basic stain cleaning. For heavily soiled floors or sticky spills, manual mopping is still recommended. Think of it as keeping floors fresh between proper deep cleans.

Will the robot work effectively on thick carpets and rugs?

The D9 Max handles most standard carpets well with its 4000Pa suction and automatic carpet detection. However, very thick or high-pile rugs may cause navigation issues. The robot can climb thresholds up to 2cm high. For problematic areas, you can set no-go zones through the app to prevent the robot getting stuck or damaging delicate rugs.

How accurate is the LiDAR mapping and does it remember multiple floors?

The 360-degree LiDAR creates detailed maps that remain stored permanently once created. The system is highly accurate for room boundaries and furniture placement. However, some users report occasional map loss requiring remapping. The robot supports multi-floor mapping, so you can carry it between levels and it will create separate maps for each floor.

What happens if the robot gets stuck or encounters an error?

Built-in sensors detect when the robot is stuck and it will attempt to reverse and find alternative routes. If completely stuck, it sends notifications to your phone. The robot has anti-fall sensors to prevent tumbling down stairs. When moved manually during cleaning, place it back in the exact same spot to avoid map confusion and restarting the cleaning cycle.

How often do the brushes and filters need replacing?

Side brushes typically last 3-6 months depending on usage frequency and floor conditions. The main brush may need replacement every 6-12 months. Filters should be cleaned weekly and replaced every 2-3 months. The app provides maintenance reminders based on usage. Replacement parts are available from Dreame directly or third-party suppliers at lower costs.

Does the robot work with 5GHz WiFi networks?

No, the D9 Max only connects to 2.4GHz WiFi networks. Most modern routers broadcast both frequencies, so ensure your 2.4GHz band is enabled and the robot is within good signal range. The robot and your phone must be connected to the same network for app functionality to work properly.

How long does the initial mapping process take?

First-time mapping typically takes 1-2 hours depending on your home size and complexity. The robot moves methodically around each room creating the map whilst cleaning. Ensure the battery is fully charged before starting as partial battery may result in incomplete mapping. Once mapped, subsequent cleans are much faster and more efficient.

Can I schedule different cleaning modes for different days?

Yes, the app allows detailed scheduling including specific rooms, cleaning modes and times for different days. You can set weekday schedules for high-traffic areas and weekend deep cleans for the entire home. Each schedule can use different suction levels and include or exclude mopping functions based on your preferences.
