Sometimes. You may notice that certain types of cleaners you might use in your pool trigger false alarms. Suction and pressure cleaners don’t typically cause false alarms. But if you have purchased a robot-style cleaner, you may find that it sets off the alarm. This is likely due to the fact hat these cleaning systems can mimic sub-surface signals that an object (or child or pet) does when it falls into the pool. If you find that your cleaning system does tend to trigger a false alarm, we recommend turning the alarm into ‘swim’ mode prior to letting your robot do its job.
