Cecotec Conga flashing red light and 2 beeps: bumper error
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On the Conga 1990 Connected and 2290 Ultra, 2 beeps with a flashing red light mean a bumper error: it is stuck or something is blocking it. Switch the robot off, remove whatever holds it and press it on both sides and the centre.
Safety first
Stop and check this first
- Do not lever the bumper with tools or open the body: warranty does not cover products disassembled or repaired by anyone outside official Cecotec service.
- Fit physical barriers at stairs or balconies, as Cecotec asks, so a collision or sensor fault cannot end in a fall.
Safe checks you can perform
- Look for objects jamming the bumper
- Press the bumper to free it
- Clean the front sensors
- Clear the area and restart

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Bumper inspection by official Cecotec service
What they doIf the bumper does not regain its travel or the warning returns in clear areas, official Cecotec support checks the mechanism and the anti collision sensor.
They must show youthe bumper moving freely and the sensor responding in the test.
In writingthe part checked or replaced and whether warranty was applied.
Warranty claim with Cecotec
What they doIf the robot is within its warranty period, ask Cecotec to handle the bumper repair as a warranty case.
They must show youwhether the fault comes from a defect or an impact.
In writingthe case number and the warranty decision.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Look for objects jamming the bumper
- Who:
- you, no tools needed.
- How:
- switch the Conga off and look all round the front bumper: remove any cable, paper, toy or debris caught between the bumper and the body.
- Result that matters:
- a bumper with nothing holding it back.
- If something was wedged in:
- once removed, the warning should clear.
- If nothing is visible:
- try freeing it by pressing.
- Evidence to keep:
- a photo of what you removed from the bumper.

Press the bumper to free it
- Who:
- you, no tools needed.
- How:
- with the robot off, press the bumper gently on both sides and in the centre, as Cecotec describes for the Conga 1990 Connected. It should push in and spring back without catching.
- Result that matters:
- the bumper moving freely again.
- If it springs back and moves well:
- switch on and test.
- If it stays pushed in or rubs:
- do not force it and contact official service.
- Evidence to keep:
- a short video of the bumper as you press it.

Clean the front sensors
- Who:
- you, no tools needed.
- How:
- wipe the anti collision sensor area and the robot's other sensors with a clean, soft, dry cloth. Do not apply cleaning products directly to them; Cecotec recommends this cleaning every 35 hours of use at most.
- Result that matters:
- sensors free of dust that could confuse the robot.
- If they were dirty:
- after cleaning, the robot should navigate without the warning.
- If they were clean:
- clear the cleaning area and restart.
- Evidence to keep:
- a note of when you last cleaned the sensors.

Clear the area and restart
- Who:
- you, no tools needed.
- How:
- before switching the Conga on, pick up objects and cables that could affect its operation and keep it away from clothing and curtains, as the safety instructions ask. Then switch it on and start a clean.
- Result that matters:
- a clean without impacts that jam the front again.
- If it cleans without a warning:
- the jam was a one off.
- If the flashing red light with 2 beeps returns in a clear area:
- ask official service for an inspection.
- Evidence to keep:
- the room where the warning keeps appearing.

What it means
The Conga 1990 Connected and Conga 2290 Ultra manuals link a flashing red light with 2 beeps to a bumper error. Cecotec asks you to check whether the bumper is stuck, remove any object blocking it and press it on both sides and in the centre to free it. The bumper carries the anti collision sensor, and the robot's sensors collect dust and should be cleaned every 35 hours of use. The signal alone does not show that the sensor itself is faulty.
