Samsung robot vacuum cleaner no longer charges, what to do?

The Powerbot, Navibot or Jet bot robot vacuum cleaners from the Samsung brand are renowned for their performance and reliability. Nevertheless, like any electronic device, it happens that these devices encounter malfunctions. So when your Samsung robot vacuum cleaner no longer charges, this is the tragedy. Several causes can be at the origin of this failure: incorrect adjustment, power supply problem, faulty charging unit, battery out of order or even faulty connectors... Discover the checks and manipulations allowing you to identify and resolve the malfunction .

What to do when your Samsung robot vacuum no longer charges?

Warning : The maintenance and dismantling operations of the robot vacuum cleaner are all done with the power off. Risk of electric shock and damage to the device. If you are not competent for the manipulations, call a professional. 

Check your Samsung robot vacuum settings

At first, when your Samsung robot vacuum has a charging problem, it may come from a wrong setting or a bad use. Then do a few checks:

1 – Check that the emergency switch (I/0) located under the robot vacuum cleaner is in position alight. Indeed, if the switch is off, the vacuum cleaner is electrically cut off. It can then neither operate nor charge.

2 - Check that the charging pins of the Samsung robot vacuum cleaner and those of the docking station are aligned. Indeed, it happens that the vacuum cleaner does not position itself correctly on the charging unit and that it cannot then charge.

3 - Clean the vacuum cleaner (cell, dust container, filter). You can also clean the inside of the vacuum if you have electrical clearances. However, be careful. If your vacuum cleaner is still under warranty, do not dismantle it as this may invalidate your rights.

4 – Check that you have the robot vacuum fully charged before using it. If not, load it manually. Indeed, even when the device is not used, it is discharged. Therefore, it is advisable to constantly leave it on the docking station. Note that it takes about 4 hours to fully charge the device.

5 - If your Samsung robot vacuum no longer charges automatically but charging manually, check that the docking station is not in a dark area. Also check that it is easily accessible for the robot. If these criteria are not met, the device may have difficulty locating the load. In addition, make sure that the docking station is always powered on and therefore that the charger is connected to a power outlet. Otherwise, the robot will not be able to locate the charging base.

Check the electrical outlet of your Samsung vacuum cleaner

If your Samsung robot vacuum no longer charges and the charging indicator does not light up, this means that it is probably not not powered. The problem may be with the electrical outlet or the charging unit. First, make sure that the problem is not simply due to the electrical installation of your home by carrying out these few checks:

  • Check that the electrical outlet that your vacuum cleaner's charging unit is plugged into is working. To do this, connect another functional device to it.
  • If you are using a power strip or extension cord, remove them. These accessories can be defective, but also create electrical noise that can interfere with the charging of the vacuum cleaner.

Check that the charging unit is working

Samsung vacuum charging issues are often not directly related to the device, but rather to something external. Moreover, in the vast majority of cases, when your samsung robot vacuum cleaner won't charge, the problem is caused by charging unit failure. This consists of the charger (power cord and adapter) and the charging station. You will then need to check these two elements.

1 – Check the status of the charger

If your Samsung robot vacuum cleaner is no longer charging and the charging indicator does not light up, there is a good chance that the charger be the source of the problem. In more rare cases, it happens that the light is on because the charger is still sending a current charge but it is too weak to manage to charge the device. Therefore, in any case, we advise you to check the charger.

First, start with visually inspect the power cord. If it looks damaged (melted, stripped, cut, burnt etc.), it is most likely faulty. Likewise if the power plug appears bent, damaged or burnt. In this case, the charger is probably not delivering the current needed to properly charge your Samsung robot vacuum.

To be sure, we recommend that you push the test through more concrete means. You can either try to connect the docking station with another charger compatible with your Samsung vacuum cleaner model or measure charging voltage if you have electrical clearances by proceeding as follows:

  1. Plug the charger into the electrical outlet
  2. Position the multimeter on direct current voltmeter
  3. Using the test probes, read the voltage across the terminals of the charger output plug

If the voltage is approximately in line with that indicated on the charger, it is not defective. If the voltage is zero or less than indicated, the charger is out of order and then it is probably responsible for the charging problem of your Samsung robot vacuum. You will need to replace it. Be careful that it is compatible with your model of robot vacuum cleaner. The best is to buy an equivalent. In any case, avoid counterfeits.

2 – Check the status of the charging station

When your Samsung robot vacuum cleaner no longer charges, the origin of the problem can also come from the dock.

To start, check the charging terminals from the docking station. If they appear dirty or oxidized, this could lead to poor contact. Then clean them with a dry cloth. Caution, carry out this operation with the station switched off. If you notice that the terminals are bent, the device may no longer be able to snap on them. In this case, the station will need to be replaced so that the Samsung vacuum cleaner can charge normally again.

Continue to check the charging station by electrically testing. Indeed, although it may seem functional at first glance, a power supply or internal component failure may no longer allow the robot vacuum cleaner to be powered. To electrically check the docking station, here is the procedure to follow:

  1. Connect the charging station to the electrical outlet
  2. Position the multimeter on direct current voltmeter
  3. Place the test tips on the terminals

If the voltage is good, the station is not faulty. On the other hand, if the voltage is zero or less than indicated on it, then it is responsible for the charging problem on your Samsung robot vacuum cleaner. In this case, it will have to be replaced.

Check the battery of your Samsung robot vacuum cleaner

Finally, when your Samsung robot vacuum no longer charges, it also happens that the problem comes from the battery. Some symptoms are typical of this failure: battery no longer holding a charge, charging light that comes on but never goes out or even a vacuum cleaner that comes on but goes out by itself after a few minutes.

Samsung robot vacuum cleaner not charging what to do?

In this case, you will need test the battery by proceeding as follows:

Warning : Risk of electric shock and damage to the vacuum cleaner. Before testing the battery, make sure it is disconnected from the vacuum cleaner. Use an anti-static mat and gloves against electrocution. If you do not have the skills to carry out the manipulations, we strongly advise you to contact a professional. If your vacuum cleaner is still under warranty, do not proceed with the dismantling of the device which would make you lose your rights. Immediately contact the Samsung customer service. 
  1. Charge the battery to its maximum capacity. If you feel like the battery isn't charging, leave it plugged in for a full charge anyway.
  2. Once the battery is fully charged, remove the Samsung robot vacuum from its charging unit.
  3. Turn the vacuum over, remove the screws and the cover to access the battery. Remove it from the vacuum and measure the voltage across it.

• If the indicated voltage is zero or less than that indicated on the battery, it is faulty. So that explains why your Samsung robot vacuum cleaner is not charging. Replace it with a new battery, preferably original. Be careful, avoid at all costs counterfeits which, in addition to being less qualitative, do not always respect the applicable safety standards. They can therefore affect the performance and life of your device.

• If the voltage is good, put the battery back in the vacuum cleaner, close the cover and start the device. Then time the autonomy of the robot vacuum cleaner. If it holds a charge for less time than it should, the battery is most likely faulty. You will also need to replace it.

How to solve the problem if despite everything your Samsung robot vacuum cleaner still does not charge?

In the overwhelming majority of cases, your Samsung robot vacuum won't charge due to the charging unit or the battery. However, in more rare cases, it also happens that the problem comes from a faulty internal component such as a disconnected or damaged connectors, for an broken sensor,faulty on/off switch, Or the faulty electronic card. Unfortunately, at this stage, electrical authorizations are necessary since it will be necessary to disassemble the vacuum cleaner, test the components one by one, then find the reference of the defective component and replace it. We therefore advise you to call a professional repairman.

If your Samsung robot vacuum cleaner that has a charging problem is still entitled to warranty (2 years manufacturer in France), contact the Samsung after-sales service. You will then obtain a personalized solution for your case. Whether or not your Samsung robot vacuum is under warranty, you can also contact a authorized service center near you. If the device is no longer entitled to warranty, do not forget to request a quote to avoid unpleasant surprises. Finally, you can also contact an independent professional repairer. Once again, do not hesitate to request a quote.
