Dreame card moved, twisted, broken – these are the reasons!

Fortunately, the shifting or twisting of the map created by a Dreame vacuum robot rarely occurs. However, I have experienced cases where the robot simply destroyed the map for no apparent reason. But why does the Dreame do this?

Dreame card moved, twisted, broken – these are the reasons!

It is usually unexpected situations that cause a Dreame vacuum robot to ruin the map it has created. Many factors can play a role. I have looked into the topic and would like to show you in this article why a Dreame vacuum robot simply twists, moves or destroys the saved map.

Possible causes and appropriate solutions

Here I will give you an overview of the most common reasons for a twisted or broken card. Of course, there is a solution for this.

The charging station was placed incorrectly

• Cause : The most common mistake is actually placing the charging station incorrectly from the start. If you don't leave enough space for the robot and squeeze it into a tight niche, it could see objects and walls at an angle right from the start. Placing it in the middle of the room or against a slanted wall is also not beneficial. The robot will quickly create a slanted map.

• Solution : Place the charging station so that it is against a straight wall and at least 50 cm away from any furniture or objects on either side. The robot also needs space in front of the station to be able to dock reliably. The distance in front of the station should therefore be at least 1 m.

The sensors of the vacuum robot are dirty

• Cause : Over time and after many cleanings, the Dreame may become dirty. Fine dust can penetrate deep into the sensors and disable them or block them to the point that the robot becomes completely confused.

• Solution : Take care of your Dreame. As soon as the robot is dirty, it should be cleaned. In very dirty households, this can happen after just 3 days, in other households only after 1-2 weeks. Free the robot of dust and dirt and carefully clean all sensors.

The Dreame gets stuck during cleaning

• Cause : Every cleaning can bring its own dangers. If the Dreame robot vacuum cleaner has difficulty on raised surfaces such as doorsteps or high carpets, it can quickly get stuck. It always tries to free itself when it gets stuck and this can lead to the map becoming twisted. Likewise, sagging fabrics under sofas can block the robot and ultimately cause the map to shift.

• Solution : If you have problems, watch the cleaning process closely. If you notice that the Dreame is having trouble with a particular spot, then remove the danger spot. If the door threshold is too high, it is a good idea to install a ramp. If there is hanging fabric under the sofa, it usually helps to cut it out from under the couch or to equip the couch with new, higher legs.

The Dreame detects floor-to-ceiling windows & mirrors

• Cause : A floor-to-ceiling mirror or even a floor-to-ceiling window turns out to be a new room for the laser unit on the robot. This fake room is created because the emitted laser beam can no longer be captured. The Dreame therefore thinks that there is a new room there that it cannot reach. However, it will map the room and this can lead to other rooms being overlapped.

• Solution : All you can do is tape the lower part of the mirror or window or cover it in some other way so that the laser is not directed into oblivion. Today, there are beautiful decorative glass films that imitate a matte sandblasted surface.

The vacuum robot detects chrome-plated or reflective objects

• Cause : In this case too, a reflective or chrome-plated surface can cause the laser beam to be deflected. This has already happened to me with a chrome-plated laundry basket. The laser is deflected by the reflective surface and is no longer picked up by the Dreame. This can cause the map to shift because it is completely confused and lacks the information.

• Solution : Remove any chrome or mirrored items. If you have mirrored furniture legs, tape them off or replace them with others.

The Dreame is lifted during cleaning

• Cause : Another common reason why the map is shifted is if the robot is suddenly lifted up during cleaning. The Dreame follows a pre-planned path through your home. If it is interrupted unexpectedly, it can confuse the robot vacuum and lead to a twisted map.

• Solution : Never lift your Dreame while it is cleaning. Switch it off using the controls before lifting it and thus prevent further cleaning. Simply pausing the cleaning is sufficient.
