Roborock S5 Robotic Vacuum Cleaner Features and Specifications

Roborock S5 Robot Vacuum Cleaner features advanced LDS Smart Navigation based on the LIDAR (laser) sensor, which allows the unit to make high-precision map of the cleaned area and to save that map.

LDS Smart Navigation sensor is positioned on top of the unit, slightly increasing its height - unit physical dimensions are 3.78 inches (9.6 cm) height, 13.78 inches (35 cm) diameter and the unit weighs 7.72 lbs (3.5 kg).

As one can see, unit is taller than most of the similar units (3.78 inches vs 3-3.5 inches), but nonetheless, it is still very compact unit, able to reach and clean under most of the beds, sofas and similar floor objects.

Personally, such advanced navigation system more than compensate for slight increase in height. After all, it allows the unit to create and save home map, to display running route, to have defined cleaning zones, no go zones etc.

Also, LDS navigation system enables the unit to resume cleaning tasks after fully recharging the battery - so-called 'recharge and resume' feature.

roborock s5 water tank slide

Roborock S5 is 2-in-1 unit - it can be used as robot vacuum cleaner and as mopping robot. When used as mopping robot, water tank with mopping pad is attached at the rear bottom of the unit.

Water tank capacity is ~150 ml, allowing wet mopping between 45 and 60 minutes. Bionic wet mopping system dispense water uniformly, preventing the mop pad to leave water streaks and water droplets on the mopped floors.

Also, when the robot is at rest, water dripping is shut down - this is very useful when the unit return to the docking station for recharging. Nonetheless, it is highly recommended to detach the water tank and mop pad from the unit when recharging.

roborock s5 mopping

Roborock can be used for mopping of all sealed floors that are intended for such type of cleaning, like tiles, marble, sealed hardwood floors, vinyl, laminate etc.

When cleaning/vacuuming carpeted areas, unit should not be used for both vacuuming and mopping.

Note: Roborock S5 is available in several colors: white, white-rose, and black. Also, its label varies depending on the color and market (for example, S5, S51, S55 etc), but all those models are Roborock S5 robot vacuum cleaners and floor mops.

Roborock S5 comes with high-capacity 5200 mAh lithium battery, enabling the unit to operate up to 150 minutes and vacuuming up to 250 m2 of bare floors.

When vacuuming carpeted areas, operating time and cleaned area is decreased, depending on the carpet height, amount of dirt and other factors that can limit or prolong operating time of Roborock S5 and similar units.

When the battery is discharged, unit automatically locates charging station, charge it self and if required, resume the cleaning task.

When positioning charging station, it is important to leave some area free around it, to help the unit locate it. When the battery is almost fully discharged, it takes up to 240 minutes (4 hours) to recharge the battery.

Note: Roborock S5 is advanced robot vacuum, but nonetheless, it is not too hard to use and maintain. But, just in case, when the unit arrives, be sure to read the manual thoroughly.

cliff sensorsLDS sensor is combined with the full set of other sensors, including cliff sensors, wall sensors and magnetic sensors.

Cliff sensors help the unit detect cliffs (stairs, for example), preventing the unit to fall down the stairs.

Wall sensors help the unit detect the objects and walls, helping the unit to follow the wall and clean along its edge.

Magnetic sensors help the unit detect the magnetic boundary strips that the users can set on the floor to create permanent or temporarily no-go zones. Magnetic strips are not included, but can be ordered later, if required. Since Mi Home App (available for both Android and iOS) support virtual walls and no-go zones, most of the users don't even use magnetic strips.

Roborock S5 features only one side brush, but it is dynamic, variable-speed side brush that spins at 330 rpm when cleaning along the wall edge. When vacuuming floors, it spins at 130 rpm and gently sweep the debris toward the main rotating brushroll. Such variable speed side brush saves the energy and prevents dirt from flying away.

Main brushroll features 'floating design' - main brushroll system floats up and down and cling to the floor surface, cleaning the floors more thoroughly.

Main brushroll is not maintenance free brushroll - it is up to the user to periodically clean it and remove tangled hair and fibers.

roborock s5 vacuuming

Roborock S5 features maximum suction of 2000 Pa (2 kPa), which is excellent suction for robot vacuums.

Its suction is also variable, depending on the cleaning mode, floor, dirt type and similar, and it includes Carpet, Quiet, Mopping, Balanced, Turbo and Max mode.

Note: Roborock S5 features so-called 'carpet pressurization mode' or 'carpet boost' where unit automatically recognize carpeted areas and automatically increase the suction to clean the carpets more thoroughly.

To help traverse various surfaces, Roborock S5 is designed to climb over obstacles up to 0.79 inches (2 cm) in height, without water tank. When the water tank is installed, unit can climb obstacles up to 0.6 inches (1.5 cm).

During operation, maximum noise level is ~68 dB, however, the unit also features 'Quiet' mode, if very quiet operation is required.

Dirt cup capacity is 0.48 liters and it could be perhaps larger. However, if the unit is used regularly, and dirt cup emptied on a daily basis, it is more than large enough.

Air filtration is good and is based on the mechanical air filter. Air filter is labeled as HEPA filter, E11 class - it is able to capture 95% of very small particles of dirt (down to 0.3 microns).

Air filter is washable, leading to decreased maintenance costs. But, after some time, it should be replaced with the new one.

Note: air filter is washable, but it should be assembled back into the unit only when it is fully dry. Roborock S5 is designed for dry dirt only, despite being 2-in-1 unit. Operating the unit with the wet filter can damage the unit and void its 1-year limited warranty.
