3.4 Scanning (Mowing) 
Keep in mind that the Robomower will not mow all the grass on its first pass, in fact it will leave 
uncut  grass  in  between  many  of  the  legs  it  makes.    This  is  expected  and  is  entirely  normal. 
These  uncut  areas  will  be cut  on  subsequent  passes  of  the  Robomower  across  the lawn.  Just 
like a dishwasher,  wait  until  the  job  is finished before you can  appreciate the  results.    The 
Robomower  will  continue  to  run  for  the  amount  of  time  selected  or  for  the  default  ‘MAX’  time, 
which  is  generally  2.5  to  3.5  hours,  depending  on  grass  type  and  condition.  (RL550  Europe  2 
hours) See Chapter  6,  Operator Settings  and  Advanced  Features
 for  more detail  on setting 
operating time. 
Note:  There is an option to skip the edge mowing and to start scanning (mowing) the main area 
of the lawn. Simply press the ‘GO’ button two times in sequence when starting the mower.   
3.5 Mowing Complete 
When the  Robomower  has  operated the  allotted  time,  it  will simply stop in the lawn, waiting for 
you  to drive  it  back  home  and  plug it into  the  charger,  ready  for  the  next  mowing session. The 
LCD will display a text message as seen in Figure 3.7 if the mowing time is set to the default time 
of  ‘MAX’  or  the  message  as  shown  in  Figure  3.8  if  the mowing  time  has  been  selected  to  any 
time other than ‘MAX’. 
If the Robomower has completed its’ mowing and it is more than 20 minutes before you arrive to 
move  it, the LCD  screen will be blank.  The Robomower will shut itself down into  a sleep mode 
after  20  minutes  of  inactivity  at  all  times.  This  is  an  energy  saving  feature.  Pressing  the  ‘GO’ 
button  or  removing  the  Manual  Controller  from  the  holder  will  ‘wake  up’  the  Robomower  and 
display the message that was on the LCD when it went into sleep mode.  In this case, either the 
message in Figure 3.7 or 3.8.
