A. Battery
and
Charging
1.
How
long
does
it
take
to
fully
charge
the
robot?
It
takes
about eight
hours
to
fully
charge
the
robot.
2.
Why
does
it
take
so
long
to
charge
up
the
battery?
The
robot
uses
a
slow
charging
technology
which
could
keep
up
the
work
performance
and
lif
span
of
the
rechargeable
batteries
better.
3.
Why
is
the
green
lamp
still
blinking
after
8
hours
of
charging?
As
the
recharge
function
relies
on
the
timer
inside
the
robot,
in
case
the
charging
power
input
has
been
interrupted
during
the
recharge,
the
timer
will
re-start
counting
(so
the
power
indication
lamp
will
still
be
blinking
in
green.)
It
will
stop
again
after
8
hours
of
uninterrupted
charging.

Would
I
get
electric
shock
if
I
touch
the
robot
when
it
is
recharging?
NO.

to
turn
off
the
robot
before
charging
it?

6.
Would
the

be
overcharged
or
get
burnt
if
it
is
connected
to
the
adaptor
all
the time?
NO.
The
recharge
will
stop
automatically
after

recommended
to
unplug
the
adaptor.
7.
What
would
happen
if
I
start
using
the

fully
charged?
It
will
still
work
until
the

drops
to
a
certain

8.
How
long
is
the
battery
life?
When
do
I
need
to
replace
with
new
batteries?
Lifespan
of
Ni-MH
batteries
is
usually
around
9-12
months
(it
will
also
depend
on the
usage
and
storage
condition).
When
the
batteries
start
to
age,
the
working
time
will
drop
gradually.
When
the
working
time
drops
to
a
level
that
the
robot
can not
clean
up
your
home
effectively
(you
still
find
obvious
dirt
on
floor
after
the
cleaning
program)
you need to replace
with
new
batteries.
