Roborock S7 Max Ultra (Black)

How often does the dust bag need replacing?

The 2.5L dust bag typically requires replacement every seven weeks for average-sized homes with normal debris levels. However, homes with pets or high foot traffic may need more frequent changes. The app will notify you when the bag is full and replacement bags are readily available from Roborock.

Can it clean different floor types in one session?

Yes, the VibraRise technology automatically detects floor type changes and lifts the mop pad 5mm when transitioning from hard floors to carpets. This prevents wet marks on carpets whilst maintaining effective cleaning on both surfaces. The 5500Pa suction works effectively on all floor types including hardwood, tile, laminate and various carpet pile heights.

How does the obstacle avoidance work in practice?

The reactive technology uses multiple sensors to measure distances to objects in real-time, whilst LiDAR creates detailed room maps. This combination allows the robot to navigate around furniture legs, cables, shoes and other obstacles without getting stuck. It can even clean effectively in complete darkness using these navigation systems.

What maintenance is required for the mopping system?

The base station automatically washes the mop after each cleaning cycle and applies warm air drying to prevent bacterial growth. You'll need to refill the 3L clean water tank periodically and empty the 2.5L dirty water tank. The system also self-cleans the dock components, significantly reducing manual maintenance compared to traditional mopping robots.

How accurate is the mapping and room recognition?

The LiDAR navigation creates precise 3D maps of your home including furniture placement and room boundaries. Multi-level mapping supports homes with multiple floors, storing separate maps for each level. The app allows you to label rooms, set cleaning schedules for specific areas and create virtual barriers without physical boundary strips.

Can it handle pet hair effectively?

The 5500Pa suction power and durable all-rubber brush design make it highly effective for pet hair removal. The rubber brush prevents hair tangling that commonly occurs with bristle brushes. The auto-emptying feature is particularly beneficial for pet owners as it reduces exposure to allergens during maintenance.

What happens if it gets stuck or encounters problems?

The smart app automatically detects areas where the robot might get stuck and suggests them as permanent no-go zones. If it does encounter issues, it will return to the dock and send a notification to your phone explaining the problem. The 'Always Continue Cleaning' feature ensures it resumes cleaning after resolving minor obstacles.

How long does the battery last and what's the charging process?

The lithium-ion battery provides extended cleaning time for large homes and the robot automatically returns to dock when battery levels are low. Off-peak charging can be scheduled to take advantage of lower electricity rates. Once recharged, it automatically resumes cleaning from where it left off until the entire programmed area is complete.
