How long does the battery last and what area can it clean?

The Roborock QV 35S has sufficient battery life to clean up to 1,200 square feet in a single session. The robot features 30% faster charging compared to previous models and when the water tank is filled once, it can mop up to 3,552 square feet. The battery automatically returns to the dock for recharging when needed and resumes cleaning where it left off.

Does the self-emptying dock really work for 7 weeks without maintenance?

Yes, the multifunctional dock automatically empties the robot's dustbin into a larger dust bag that can hold debris for over 7 weeks of regular use. The dock also self-washes and dries the mop pads after each cleaning session, refills the water tank automatically and handles all maintenance tasks. You only need to replace the dust bag and refill the dock's water reservoir periodically.

Will this robot vacuum work effectively on both carpets and hard floors?

The QV 35S is designed for multi-surface cleaning with intelligent floor detection. On carpets, it uses the full 10,000Pa suction power for deep cleaning and automatically lifts the mop pads 10mm to avoid dampening. On hard floors, it adjusts suction and uses the spinning mop system with customisable water flow. The robot can vacuum carpets first, then mop hard floors in the same cleaning cycle.

How does the anti-tangle brush system work for pet hair?

The robot features a rubberised floating main brush and specially designed arc-shaped side brush that are SGS-certified for 0% hair tangling. The brushes are engineered to prevent pet hair and human hair from wrapping around them, making maintenance much easier. This makes it particularly effective for homes with multiple pets or family members with long hair.

Can I control which rooms get cleaned and when?

Yes, the Roborock app provides complete control over cleaning schedules and areas. You can select specific rooms or zones for cleaning, set different cleaning schedules for different areas and create No-Go Zones. The SmartPlan feature automatically customises cleaning schedules based on room types and floor surfaces, whilst you can also initiate temporary cleaning sessions or skip certain areas as needed.

How accurate is the mapping and navigation system?

The PreciSense LiDAR navigation system scans 360 degrees to create highly detailed maps of your home. It supports up to 4 different floor maps and can automatically switch between them for multi-level homes. The system creates efficient cleaning routes and remembers room layouts, furniture positions and obstacles. Combined with Reactive Tech obstacle avoidance, it navigates reliably around furniture and clutter.

What maintenance is required for the mop system?

The mop system is largely self-maintaining. The dock automatically washes the mop pads with clean water after each cleaning session and uses cold air drying to prepare them for the next use. You'll need to periodically refill the dock's clean water reservoir and empty the dirty water tank. The mop pads themselves are replaceable and should be changed when they show signs of wear.

Is the robot suitable for homes with stairs and multiple levels?

The robot is designed for single-level cleaning and cannot climb stairs. However, it supports up to 4 different floor maps, so you can manually move it between levels and it will automatically recognise which floor it's on. The robot has cliff sensors to prevent falls down stairs. For multi-level homes, you would need to manually transport the robot between floors, though the dock can remain on one level.
