    beep” tone if you have successfully completed the schedule setting program.

    Note: When you are using the remote to schedule a cleaning time, make sure the remote is

    the robot is always powered on, otherwise the schedule setting will not work.

    If you want to cancel the schedule time, adjust the time to 00:00.


  • Why has the robot stopped working?

    Make sure that the power switch on the robot is set to “ON.” If the robot is still not working, it may have ran out of power and will need

    to be manually placed on the charging base.


  • How often do I need to clean the dust bin?

    The capacity for the dust bin is 0.45L. If will fill up quickly depending on how much debris is on your floor. It can still work when it's full,

    however, it cannot store more debris, so it must be emptied when full.


  • Why has the robot’s cleaning efficiency decreased?

    1.The filter may be clogged. Remover the filter, and clean it with warm water, then let it dry completely, then place it back in the filter slot. If the filter is over 6 months old, it is advised to replace it with a new filter.

    2. Pick up large items and keep areas to be cleaned open.

    3. Clean the side brushes, bristle brush and sensors regularly.

    4. Empty the dust bin before using, which will allow for better airflow and efficient cleaning. 


  • Why is the charging base not working?

    1. Check whether the indicator light on the base is shining or not. If not, it indicates that the socket is not compatible with the charging base. If this is the case, use the AC adapter to plug directly into the robot to charge.

    2. It is advised not to place the machine into the charging dock by hand, because electrodes

    of the charging dock are too small to be targeted accurately, which will cause the robot to not charge.

    3. It is advised to control the robot back to the charging dock automatically by placing the robot in front of the charging dock and pressing the “HOME” button on the remote. 


  • Why has the noise level of the robot increased?

    Turn off the power switch, take out of the dust box and clean off debris, with the bottom upwards.

    1. Check whether the side brush mouth is blocked or not.

    2. Check and clean off side brushes.

    3. Check whether the robot is in “MAX” mode (this mode is much louder because the suction is increased). 


  • Why does the machine get stuck when transitioning from hard floor to carpet?

    Make sure the height difference between the carpets and the floor are no more than 15mm. 

  • Why is the robot getting stuck?

    Check whether edge wheels and side brush are stuck due to foreign bodies, and pick up wires and curtains, as well as frayed carpet edges.  

  • Why does the robot flick dust/debris around?

    The side brushes, which are designed to pull dust/debris toward the vacuum intake, will sometimes flick dust/debris away. This is normal, and the dust/debris will be cleaned in subsequent passes by the robot. 

  • Does the robot vacuum up long hair sufficiently?

    Yes, however, some long hairs will be picked up by the robot will be tangled in the side brushes and bristle brush. Remove accumulated hair periodically. 



  • Why can the scheduling function set a start time, but cannot set an end time?

    The schedule function can appoint the cleaning time, and the robot will return to the charging dock when cleaning is completed or when the battery is close to running out of power. If it is necessary to end a cleaning cycle in advance, press the “CLEAN” button on the remote controller. 

  • Does the robot plan a cleaning route?

    This product randomly sets the cleaning route and cannot plan the cleaning route. Fear not, for we plan to introduce these features in subsequent models, so check back periodically!

  • Why is the robot doing repeat cleanings?

    Repeated cleaning is normal, and the machine works for about 2 hours. Thus, many places need to be cleaned many times in order to achieve a complete clean. 

  • How do you set the robot into “sleep mode?”

    Point the remote control at the robot and press the “CLEAN” key - the indicator light will flash for 15 seconds, then, the robot will automatically enter into sleep mode. While in sleep mode, it is necessary to press the “CLEAN” key on the robot or remote controller to awake it. 

  • Why did the robot fail to enter into sleep mode?

    If the robot is continuously charged when charged fully, it cannot enter into sleep mode. 

  • Why is my robot falling from elevated places (cliffs)?

    1.The carpet cannot exceed the border of the floor, or the robot will still sense carpet underneath it and fall.

    2.Ensure there are no large power appliances around the cliff, or otherwise appliances will hang off the cliff and guide the robot off the cliff. Please add a guardrail on the edge of the cliff if you can’t move said appliances. 


  • Why is the power running out quickly?

    This could be caused by multiple issues:

    1. Place the vacuum on the charging dock or turn off the power switch when unused.

    2. When A4 uses MAX mode, the fan speed becomes higher and suction power increases, which uses more power, thus draining the power quickly. 3. The battery may be damaged/old. Contact technical support if you have tried 1&2 without success. 


  • How do I switch the robot to perform different modes of cleaning?

    Aim the remote control at the robot and press the mode switch key on the remote controller to switch between Auto/Spot/Edge cleaning modes. 

  • Will the robot automatically plan the cleaning route?

    The robot will perform a random route on its own. 

  • Does new robot need to be charged for 12 hours?

    Yes, it does. The robot needs to be charged for 12 hours for the first 3 times in order to fully activate the battery. This will increase the endurance of the battery and ensure a normal battery life. 

  • Why does the robot only work for a few minutes after a full charge?

    1. The machine was not effectively charged. Kindly confirm if the power switch is "ON" while charging.

    2. The battery of new machine loses endurance over time. It is necessary to activate the battery when this happens.

    3. Check whether edge wheels, side brush and bristle brush are stuck due to foreign bodies. 


  • How do I activate the battery?

    Charge the robot for three minutes, take off the charger, then charge for three minutes again, and then take off the charger for several seconds. Repeat above actions three times.

    Finally, charge the robot for 12 hours. 


  • When should I replace the filter?

    This depends on the frequency of use and the cleanliness of the filter. The filter is generally replaced every two-three weeks. If it is not dirty, it can be replaced every six to eight weeks. 

  • Why is it hard to take the dust bin off of the robot?

    Search for the small hole in the back of the robot, and press the lever down to release. This will allow the dust bin to be removed with ease.

  • It can set working time ,but can not set end time .

    You can schedule to let the robot start cleaning from a certain time .It will be back to charging base after finishing or low battery. Please press the clean button on remote control , if needs end early.
