18. Q: Why don't Roborock and Xiaowa robotic vacuum cleaners use an electric water tank?
(Updated on November 29, 2018)
A: 1. Although electric tanks have a large water volume, the dimensions of the mop are limited.
The mop's cleaning capacity gradually decreases as time goes by. When at maximum cleaning
capacity, not only does the continuous water output make it difficult to clean the floor, but it
would also cause the dirty water to flow back into the system. As a result, the more you mop,
the dirtier it gets. The Roborock water tank capacity and its mop dimensions are perfectly
matched. As the water in the water tank is running low, the cleaning capacity of the mop is also
close to saturation. At this time, it is recommended that you wash the mop and add more water.
However, even if you continue to use it as it is, the water will not flow back into the system and
make a mess.
2. The structure of an electric water tank is complicated. All kinds of connecting pipe fittings are
easily blocked by scale deposits. The water pump is a consumable product that is prone to
failure and damage. As a result, the cleaner cannot function properly. The Roborock water tank
adopts a botanically biomimetic system. The structure is reliable and durable, and the water
tank filter can be easily replaced at a low price.

1. Q: Why does the machine turn around rather than going straight ahead in an open area?
A: The machine will clean the floor in zones. Turning around in an open area indicates that the
machine has reached the outskirts of an zone, beyond which is the next area to be cleaned and
will not be missed.
2. Q: How does it divide an area into zones?
A: By default, the machine divides areas in the principle of a 4 x 4 m matrix. As obstacles such
as walls, furniture and electric appliances are present in a home environment, it is normal for
zoned areas to vary in size.
With the map saving function enabled, the cleaner will save the map and automatically divide
an area into zones after completing the first automatic cleaning task and automatic recharge.
Afterwards, the cleaner will perform cleaning based on the zoned areas.
When there is an expansion or addition to the previously divided areas, the cleaner will
