Risk level

Usually safe to check without specialist tools.

Urgency

Medium

Quick answer

On the Rowenta X-plorer Serie 75, Error 6 means the robot is trapped or suspended, or its anti-drop sensors are too dirty: move it near its home position and wipe the bottom drop sensors with a dry cloth. On the Serie 75 S+ table, Error 6 instead indicates an abnormal water pump.

Safety first

Stop and check this first

  • Never cover or bypass the bottom anti-drop sensors, and always keep shoes, bags and other objects away from stairs and gaps: otherwise the robot will not detect the stairs properly and will fall.
  • Do not use any cleaning solutions in the robot vacuum water tank: the safety guidelines specify using water only, filled up to the maximum level mark.

Safe checks you can perform

  • Move the robot to flat floor near its home position and clear stairs
  • Wipe the three bottom anti-drop sensors with a dry cotton cloth
  • On Serie 75 S+ or W5/S6, clean the water tank, pump connections and outlet

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Anti-drop sensor or water pump diagnosis at a Rowenta Approved Service Centre
  • Do not attempt this professional task: Safety inspection at an Approved Service Centre after a fall

What a technician must be able to justify

Technician visit

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.

  1. Anti-drop sensor or water pump diagnosis at a Rowenta Approved Service Centre

    What they doIf Error 6 (or Error W5/S6) remains after wiping the three anti-drop sensors and cleaning the water tank, pump connections and bottom outlet, the Approved Service Centre tests the affected module.

    They must show youa cliff-detection or water-flow test with all modules installed.

    In writingwhich sensor or water pump component was repaired and whether warranty covers it.

  2. Safety inspection at an Approved Service Centre after a fall

    What they doIf the robot fell down stairs because objects blocked its drop sensors and shows visible damage or abnormal operation, an Approved Service Centre inspects it before further use.

    They must show youinspection results for the chassis, wheels and underside sensors.

    In writingthe service report and repair estimate from the Approved Service Centre.

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.

  1. Move the robot to flat floor near its home position and clear stairs

    No special tools

    Who:
    you, no tools needed.
    How:
    lift the robot off any threshold, light bathroom mat or fringed rug where it stopped and set it on flat floor near its home position. Also clear shoes, bags, cables or books next to gaps and stairs so the drop sensors can read the floor level difference.
    Result that matters:
    all wheels resting flat on clear floor with no obstacles beside stairs.
    If it was tilted on a rug or obstacle and starts normally:
    keep that item or mat out of its path.
    If Error 6 returns on flat floor:
    wipe the anti-drop sensors underneath.
    Evidence to keep:
    a photo of the rug or ledge where the robot stopped.

  2. Wipe the three bottom anti-drop sensors with a dry cotton cloth

    No special tools

    Who:
    you, with a soft dry cotton cloth.
    How:
    switch off the robot vacuum, turn it upside down, and gently wipe the three anti-drop sensors on the bottom and the front infrared sensor with a soft dry cotton cloth, as shown in the weekly maintenance guide.
    Result that matters:
    clean drop sensor windows free of dust build-up.
    If the sensors were dusty and the fault clears on startup:
    wipe them once a week.
    If the sensors are clean and you have a Serie 75 S+ or mopping alert:
    check the water system next.
    Evidence to keep:
    a photo of the underside showing the cleaned anti-drop sensors.

  3. On Serie 75 S+ or W5/S6, clean the water tank, pump connections and outlet

    No special tools

    Who:
    you, with clean water and a dry cloth.
    How:
    if you have an X-plorer Serie 75 S+ or the app reports an abnormal water pump (Error 6, W5 or S6), clean the water tank (using water only, no cleaning solutions), the water pump connections on both the tank and the robot, and the water outlet at the bottom, check the mop module, reinstall everything and restart after waiting 3 seconds.
    Result that matters:
    the robot restarting cleanly and releasing water normally during mopping.
    If it works after cleaning the tank connections and bottom outlet:
    a blockage was restricting water flow.
    If Error 6 or W5 persists after cleaning the drop sensors and water passages:
    contact Rowenta's Service Department for a sensor or water pump check.
    Evidence to keep:
    an app screenshot of the error and a photo of the water tank connections.

What it means

The Rowenta X-plorer Serie 75 user guide states that Error 6 occurs when the robot is trapped or suspended, and asks you to relocate it near its home position and start it; it adds that a dirty anti-drop sensor can also trigger the fault and should be wiped clean. The underside has three anti-drop sensors that Rowenta recommends wiping every week with a dry cotton cloth. On the specific X-plorer Serie 75 S+ fault table in booklet 2220003806, however, Error 6 means the water pump is abnormal (listed as Error W5 on Serie 75 and Error S6 on Serie 75 S). The code by itself does not prove that a sensor or pump has failed.

Symptoms and causes

Probable causes · in order

  • Dust build-up on the bottom anti-drop sensorsCommon

    Rowenta notes that if the anti-drop sensor is too dirty it can cause Error 6, and recommends wiping the drop sensors every week with a dry cotton cloth.

  • Robot suspended on a ledge, fringed rug or floor obstaclePossible

    The manual warns that the robot may get suspended or struggle on carpets with fringes, thick or long piles, or very light bathroom mats, and when shoes or bags sit near stairs.

  • Dirty water tank, pump connections or bottom water outlet (Serie 75 S+, W5 or S6)Possible

    In the X-plorer Serie 75 S+ table (and under codes W5 and S6), the alert points to the water pump and asks you to clean the tank, the pump connections on tank and robot, and the bottom water outlet.
