Fully charge the battery
Robotic pool cleaners are widely used in Australia because they save time and keep pools clean during long swimming seasons. While robotic pool cleaners save time, occasional issues are inevitable. The good news is that many common problems can be fixed at home.
1. Robotic Pool Cleaner Will Not Turn On
Most robotic pool cleaners will not start unless they are fully underwater. It is a safety feature, not a fault.
Common Causes and Solutions
|
Possible Cause |
What to Check |
Recommended Action |
|
Battery not charged |
Battery indicator or charging dock |
Fully recharge before use |
|
Power supply issue |
Power box or wall outlet |
Test with another outlet |
|
Water sensor not triggered |
Unit started outside water |
Fully submerge the cleaner |
|
Overheat protection |
Recently used in hot weather |
Let it cool for 20–30 minutes |
2. Movement and Pump Problems
If your robotic pool cleaner powers on but does not move properly, the issue is usually caused by blockages, worn drive components, or temporary system errors.
|
Problem |
Possible Cause |
Solution |
|
Won’t move/pump |
Not fully in water |
Fully submerge the cleaner |
|
Won’t move
|
Power button not pressed |
Press ON/OFF |
|
Basket dirty |
Clean the basket |
|
|
Impeller stuck |
Turn off and clear debris |
|
|
Moves but not pumping
|
Basket dirty or water inlet clogged |
Clean basket and inlet |
|
Low battery |
Fully charge the battery |
|
|
Pumping but not moving
|
Obstacle in the way |
Remove obstacle and restart |
|
Worn or misaligned track |
Roll or replace track |
Tips:
-
Check the pool bottom for leaves, sand, or small stones to prevent jamming.
- If the cleaner is used frequently, inspect the tracks and brushes regularly and keep spare parts on hand.
3. Poor Cleaning Performance
If the cleaner runs but does not clean well, the issue is usually maintenance-related. A robotic cleaner removes debris, but it does not replace correct pool chemistry.
Troubleshooting Guide
|
Problem |
Likely Cause |
Fix |
|
Dirt left on floor |
Dirty or clogged filter |
Rinse the filter after each cleaning cycle |
|
Fine dust remains |
Filter mesh too coarse |
Use a fine or ultra-fine filter |
|
Algae not removed |
Brushes dirty or worn |
Clean or replace brushes |
|
Missed areas |
Wrong cleaning mode |
Select full pool cleaning mode |
|
Random/strange operation |
Software glitch |
Power cycle (turn OFF → ON) |
Tips:
-
In sandy or coastal areas, use fine mesh filters to catch smaller particles.
- If the cleaner stops or behaves oddly, restarting it usually resolves the issue.
4.Wall and Waterline Cleaning
For best wall climbing, keep the pool water at mid-skimmer level.
Common Reasons
|
Cause |
Explanation |
Solution |
|
Full filter basket |
Cleaner becomes too heavy to climb properly |
Empty filter before use |
|
Low water level |
Waterline below ideal height |
Top up pool water |
|
Slippery tiles |
Reduced traction |
Check brush type and condition |
|
Worn brushes |
Less grip on walls |
Replace brushes |
Tips:
-
Keep water level around the middle of the skimmer for best wall cleaning.
-
For smooth tile pools, silicone or soft brushes improve traction.
5. Stopping Before Cycle Ends
Hot summer days can shorten run time, especially if ventilation is poor.
Possible Causes and Actions
|
Cause |
What Happens |
What to Do |
|
Low battery |
Cleaner shuts down early |
|
|
Basket full |
Reduced water flow |
Clean the filter basket |
|
Motor overheating |
Safety shutdown |
Let it cool for 20–30 minutes |
|
Software error |
Random stopping |
Restart the cleaner |
6. Cloudy Water Even When Using a Robotic Cleaner
Robotic cleaners do not replace the main pool filtration system. Cloudy water is usually caused by filtration or water chemistry issues, not a fault with the robotic cleaner.
What Else Is Needed
|
Task |
Recommended Frequency |
|
Run pool pump |
Daily in summer |
|
Clean main filter |
As required |
|
Test water chemistry |
Weekly |
|
Balance chlorine and pH |
As needed |
7. When to Contact a Professional in Australia
While many robotic pool cleaner issues can be resolved with basic troubleshooting, some situations require professional attention. Contact an authorized pool service technician in Australia if you experience any of the following:
-
Persistent error codes that continue to appear after restarting or resetting the unit
-
Water inside the motor housing, which may indicate seal failure or internal damage
-
Visible damage to the power supply, charging cable, or battery, posing a safety risk
-
The cleaner is still under warranty, as unauthorized repairs may void coverage
8. Preventive Maintenance Tips
Regular preventive maintenance helps keep your robotic pool cleaner operating efficiently and significantly extends its service life, especially under Australian climate conditions.
|
Maintenance Task |
Benefit |
|
Store the cleaner in a shaded area |
Minimizes UV exposure and slows the ageing of plastic parts and seals |
|
Rinse with fresh water after each use |
Removes salt, chlorine, and chemical residue, reducing corrosion and buildup |
|
Remove the cleaner from the pool after each cleaning cycle |
Prevents unnecessary motor strain and prolongs motor lifespan |
|
Perform seasonal inspections |
Find worn parts early and prevent major issues |
9. Finial Words
Robotic pool cleaners are reliable and efficient tools for Australian pools, but local conditions can affect their performance. Most problems can be fixed with simple checks such as cleaning filters, inspecting tracks, and ensuring proper water levels.
By troubleshooting and maintaining your cleaner correctly, pool owners can enjoy cleaner water, longer equipment lifespan, and less manual effort throughout the swimming season.
