Common Robotic Pool Cleaner Problems & Troubleshooting

These are general categories of complaints that come up across robotic pool cleaners as a category, not a diagnosis for any specific model. Always check your unit's own manual first — troubleshooting steps and safe fixes vary by manufacturer, and we're not the equipment maker.

Robot won't turn on or move

For corded models, this is most often a power supply issue — check the outlet, the low-voltage transformer, and the cable connection before assuming the robot itself has failed. For cordless models, it's usually a battery that needs a full charge cycle, or hasn't been used in a while and needs a reset per the manufacturer's instructions.

Weak suction or incomplete cleaning

A full or clogged filter is the most common cause — see our filtration guide and rinse or replace it per the manufacturer's schedule. Worn brushes or a partially blocked impeller are the next things worth checking.

Getting stuck or missing areas

Steps, ladders, drains, and tight corners are common trouble spots for any navigation system. If it's consistently missing the same area, that's more likely a pool-shape limitation of that model's navigation than a defect — see our navigation guide.

Shorter runtime than expected (cordless models)

Battery capacity degrades gradually over the life of any rechargeable battery. If runtime has dropped noticeably from when the unit was new, that's normal wear rather than necessarily a fault — though a sudden, dramatic drop is worth raising with the manufacturer, especially if still under warranty. See what a warranty typically covers.

When to contact the manufacturer

For anything electrical, anything involving the motor or pump internals, or any issue that persists after basic troubleshooting (cleaning the filter, checking the power connection, checking for visible brush or track damage), the manufacturer's own support line is the right next step — especially while the unit is still under warranty.
