Many robotic cleaners are more energy-efficient than their suction-side or pressure-side cousins — but even the most cutting-edge efficiency can sometimes be hampered by mechanical and electrical problems.
Here are some places to start when trying to pinpoint the source of robotic cleaner trouble.
As with other types of automatic cleaners, robotic cleaners are dependent on proper power from the breaker. Check for a tripped breaker, and look for loose or damaged wires around the box. A properly functioning breaker will help ensure that a robotic cleaner stays on the job.
Some robotic cleaners have drive belts that wear out over time and need to be replaced with new ones — so these should be checked at least once a year, and replaced if they’re showing wear.
Large debris can clog the pump intake of a robotic cleaner, so check to make sure it’s clear and clean. A blockage usually can be removed with a brush or tweezers, restoring suction to normal.
