DuoRoller Brush

Instead of a single main brush, the S8 now has two main brushes brushing in opposite directions to more effectively corral dust/debris towards the direction of the vacuum suction inlet.

The dual-brush design also resulted in lesser tangled hair, and makes vacuuming more effective on all surfaces – from hardwood and tiles to carpets and rugs.

HyperForce 6000 Pa Suction Power

So far, the most powerful suction rating for Roborock’s previous robot vacuums has been 5100 Pa in the S7 MaxV and 4200 on the Q7 Max.

The S8 has increased that by nearly 18% to 6000 Pa – that means the vacuum is now more effective in sucking up dust and debris from the floor.

Enhanced VibraRise 2.0 Mopping

The VibraRise sonic vibration technology scrubs the floor at a rate of 3,000 times per minute – that’s 50 times per second.

The Roborock S8 exerts a mop pressure of 6N while mopping the floor and its Carpet Boost+ feature lifts up the mop cloth by up to 5mm when it detects a carpet – so that it can switch to vacuuming the carpet.

This makes cleaning more efficient since mixed floors with carpets and hard floors can be cleaned in a single run, instead of one run for vacuuming everywhere and an additional iteration for mopping, whilst demarcating carpeted areas to avoid.

Reactive 3D Obstacle Avoidance System

The Roborock S8 uses invisible 3D structured light and infrared imaging technology to identify and avoid potential hazards on the floors, even in dark rooms.

The S8 is able to detect and bypass objects as small as 5cm wide by 3cm tall, and is able to recognise up to 42 different types of objects, such as shoes, fans or fan pedestals etc.

PreciSense LiDAR Navigation

The Roborock S8 continues the excellent tradition of its predecessors in terms of mapping out the apartment it is cleaning and planning an optimal route that does not leave any floor surfaces uncleaned.

It never fails to amaze me every time I set a new Roborock vacuum mop to create a map of the apartment from scratch – the rapidity and accuracy of the map appearing in the app is really captivating.

Every subsequent cleaning runs updates the map accordingly, while you can use the app to add invisible walls and no-go zones to control exactly where the S8 is to clean.

Something new that I like in the S8 is the ability to figure out the places where it is likely to get stuck and take extra precautions when cleaning those places in the future.

App Control

As with all Roborock robot vacuum mops, you can use the Roborock app or Xiaomi Home app to control exactly how the S8 is to go about cleaning your home.

From vacuum suction strength (power vs noise level) to scrubbing intensity/wetness, as well as the cleaning route (speed vs thoroughness) to take.

Up to four different maps (3D or flat plan view) can be stored, in case you have four levels in your house, and each map can be customised by dividing into individual named rooms, with invisible walls and no-go zones.

The app also enables scheduled cleaning as well.

Off-peak Charging Scheduling

One feature which isn’t quite applicable in Singapore yet but which is useful in countries with electricity rates that vary with time periods of the day – the S8 charging dock can be programmed to charge the robot during time periods when the electricity rates are cheap, avoiding peak hours when the electricity rates can be more expensive.

That should help owners save on power bills in this inflationary time when energy costs are rising.
