Carpet cleaner runs but suction is very weak; display shows suction fault icon or E06

Safety first: Unplug the Bosch carpet cleaner before clearing blockages.

• 1. Check dirty water tank
  • Remove and empty the dirty water tank.
  • Ensure the tank lid and seals are correctly fitted; air leaks here reduce suction.
• 2. Inspect suction hose and wand
  • Detach the hose from both the machine and the floor nozzle.
  • Look through the hose; use a flexible brush or straightened (blunt) wire to push out clogs.
  • Check the wand and any accessory tools for obstructions.
• 3. Clean floor nozzle inlet
  • Turn the unit over and inspect the suction inlet behind the brush roll.
  • Remove hair, carpet fibers, and debris that may be blocking the opening.
• 4. Clean filters
  • Remove the motor pre-filter and exhaust filter.
  • Tap off dust or wash if the manual allows; ensure filters are completely dry before refitting.
• 5. Test suction
  • Reassemble and test suction at the hose inlet.
  • If suction is still weak and E06 persists, the suction motor or internal seals may be failing and should be checked by a technician.
