25. Q: What should I do when the machine works noisily?
A:
1. The omni-directional wheel is noisy mainly because there is too
much dust under the bed or sofa at your home for the first two times. It is
recommended to remove the omni-directional wheel to clean dust inside
the bearing and use cotton swabs to remove particles inside the bearing
hole.
Besides, there are two kinds of noises made by the omni-directional
wheel. If the noise happens when the machine is turning around, please
remove the omni-directional wheel, clean the bearing holes with cotton
swabs, and use some cooking oil on the bearing. If the noise happens
when the machine is going straight, then the noise is made by the
horizontal axis. Please clean the omni-directional wheel.
2. Foreign matters are drawn into the main brush or small solid particles
are suctioned into the dust bin. Please clean the main brush or empty the
dust bin.
3. The machine clatters when retreating or turning around because on a
floor, in rare situations, black wear pads in two sides of the main brush
cover rub against the floor when retreating or turning around.
This is normal and requires no special treatment. Wear pads, after a
certain period of time, will have lower friction and thus the noise
disappears naturally. If any foreign matter is attached to the wear pads,
the noise will disappear after the foreign matter is removed.
The machine clatters transiently when going straight ahead. This may
occur when the machine travels over carpets or rugged floors. The
floating main brush clatters transiently due to upward/downward setting
of ground clearance. This requires no special treatment in normal
condition. This may occur to a new machine but only last for a short
