The water volume is insufficient	1. Check the fresh water filling level and fill the tank if necessary.2. Increase the water volume at the water volume regulating knob.3. Clean the fresh water filter.4. Check the hoses for clogging and clean if necessary.
The suction performance is too low	1. Shut down the device and drain the waste water.2. Clean the seals between the waste water tank and the cover, check for leaks and replace if necessary.3. Check that the suction hose is correctly connected to the waste water tank.4. Check the fluff filter for contamination and clean if necessary.5. Clean the suction lips at the suction bar, turn over or replace if necessary.6. Check that the cap on the waste water drain hose is closed.7. Check the adjustment of the suction bar.8. Check the suction hose for clogging and clean if necessary. When fitting the suction hose again, the white marking on the hose must lie at the retaining clip.9. Check the suction hose for leaks and replace if necessary.
The cleaning results are unsatisfactory	1. Reduce the driving speed.2. Check the brushes for wear and tear and replace if necessary.3. Check the suitability of the brush type and detergent used.
The suction turbine runs at an increased speed	1. Drain the waste water.2. Clean the float.3. Check the fluff filter and clean if necessary.4. Check the suction hose for clogging and clean if necessary.5. Check the suction bar for clogging and remove any clogging if necessary
The brushes do not rotate	1. Check if the brushes are blocked by a foreign body and remove the foreign body if necessary.
The device vibrates during cleaning	1. Use a softer brush.
The "Battery disconnected" LEDs, 80% and 100% on the charger light up several times in succession	1. The charger is in the recharging phase. In this phase, the charging state of the individual battery cells is equalized. A fault is only present if the "Battery disconnected" LED lights up continuously.
The battery cannot be charged	The battery is deeply discharged and cannot be woken up by the charger.1. Connect the charger to the power supply and to the battery.2. Press the button on the battery for longer than 5 seconds. The battery is woken up and the charging process starts.
