main brush is equipped with a cushion rubber. In addition, the surface of the omni-directional
wheel is also made of flexible materials. The machine has a total weight of
3.6kg
, thus it will
not scratch the floor during normal use.
27. Q: What should I do when the machine make an abnormal noise? (Updated on January 31,
2018)
A: 1. The omni-directional wheel is noisy mainly because there is too much dust under the bed
or sofa the first two times it is used. 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.
If the cleaner still make an abnormal noise after being cleaned and is clearly malfunctioning,
remove the omni-directional wheel and hold or balance the tail end of the cleaner with your
hands to keep its front end off the ground. Perform the cleaning task again to see if the cleaner
is free of the abnormal sound. If there is no noise, it means omni-directional wheel is at fault.
The user can continue to clean or replace it.
2. If foreign matter is drawn into the main brush or small solid particles are vacuumed into the
dust bin, please clean the main brush or empty the dust bin.
It may be that the main brush is entangled with foreign matter or jammed, and there is an issue
with the main brush cover. If there is a fault with the main wheels, it can be sent back to the
customer services (The customer service department will make a judgment and perform a BIT
test and flow test on the left and right wheels. It should be easy to reproduce such failures.)
3. Main brush gear box issue: This is caused by foreign matter becoming entangled with the
main brush or jammed. The user can inspect and clean the main brush, or remove the main
brush and the main brush cover to determine the issue. If the cleaner still makes an abnormal
noise after removal of the main brush and main brush cover or the main brush squeaks after
installation, it means sediments have found their way into the main brush gear box. In this case,
the machine needs to be sent for cleaning.
4. The machine may clatter when moving backwards or turning around because, in rare
situations, the black wear pads on the two sides of the main brush cover rub against the floor
when moving backwards or turning around.
This usually requires no special treatment. After being used for a certain period of time, wear
pads will produce less friction and thus the noise will naturally disappear. If any foreign matter
is stuck to the wear pads, the noise will disappear after the foreign matter is removed.
5. The machine may briefly clatter when moving forwards. This may occur when the machine
travels over carpets or rugged floors. The floating main brush clatters briefly due to
