Timer and Scheduling Options on Pool Cleaners

Timer and scheduling words on a listing

Pool cleaner listings use a small set of words for timing: “built-in timer”, “timer”, “delay start”, “schedule”, “app schedule”, and “smart schedule”. These words tell you how the cleaner decides when to run, not how well it cleans. A listing that carries a timer word is stating a feature; a listing without one simply leaves timing out.

The three ways a pool cleaner can be timed are easy to separate. A robotic cleaner may carry a built-in timer on the unit itself. A cordless or connected robot may rely on an app schedule. A suction-side cleaner has no timer of its own; its schedule comes from an external timer on the pool pump. Knowing which one a listing describes helps you compare cleaners across the pool cleaner guides.

Built-in timers on robotic cleaners

A “built-in timer” on a robotic cleaner listing means the robot can start a cleaning cycle on its own after you have placed it in the pool. Listings may also say “delay start”, which describes a cleaner that waits a set period before it begins. Both words describe a behavior the seller states; the actual waiting time, the length of the cycle, and how many times the timer can repeat are the maker's figures, given on the maker's page.

A built-in timer is not the same as an app schedule. The timer lives in the robot; the schedule lives in the app. If a listing says only “built-in timer” and no app words, the cleaner does not depend on a phone to start. Compare that with app connectivity versus manual control and built-in timer versus smart scheduling.

App schedules and smart scheduling

App-controlled pool cleaners list words such as “app control”, “Wi-Fi”, “Bluetooth”, “smart schedule”, and “schedule via app”. These words mean the maker's application lets you set when the cleaner runs. The app is a stated feature, but what it can store, how many schedules it holds, and whether the cleaner still runs without the app are questions for the maker's manual.

Some makers describe automation for the whole pool rather than the cleaner alone. Pentair's product pages, for example, present pool automation systems that control features of the pool and spa from one interface. That kind of scheduling is for the pool equipment, not the cleaner. A cordless robot with a charging dock may have a listing that says the robot returns to the dock between runs; that is a seller's stated feature, and the maker's manual describes how the dock and the app schedule work together. See Wi-Fi versus Bluetooth pool cleaner control for how these connectivity words read on a listing.

External pump timers for suction-side cleaners

Suction-side cleaners run from the pool pump. They have no built-in timer, and their listings usually carry no scheduling words. When you want a suction cleaner on a schedule, the schedule belongs to the pump. An external timer on the pump circuit turns the pump on and off at set times, and the cleaner runs only while the pump runs.

ENERGY STAR's pool pump page explains that pool timers allow you to reduce filtration times. That page is written for pool pumps, not cleaners, and it is a useful general reference for what a pump timer does. The site does not advise on wiring a pump timer or installing a dedicated circuit; that work belongs to a pool professional and the pump's manual. For more on how a suction cleaner depends on the pump, see suction cleaners and pump flow and how often to run a pool cleaner.

Which cleaner type lists which timing option

The table below groups the timing words you will see on a listing by cleaner type. A word belongs to the type the seller names in the title; a suction-side listing that carries no timing word is not a missing feature in the cleaner itself, because the pump timer controls it.

What to read on the maker's page

A timer word on a listing is a seller's stated detail. The maker's manual is where you read what the timer can actually do: how long the delay lasts, how many schedules the app stores, what the indicator lights show, and how the dock schedule works. The manual also describes whether the cleaner runs once and stops or repeats on a cycle. The article on pool cleaner cycle settings walks through those listing terms.

If a listing has no timer word, that is a missing detail, not a promise that timing is absent. Check the maker's page for the model to see whether a timer or app schedule is offered in another configuration. Related reading: pool cleaner control options and delay start versus immediate start.

What to pick for your situation

Questions

Does a suction-side cleaner have a built-in timer?

No. A suction-side cleaner runs off the pool pump, so its schedule is set with an external timer on the pump circuit. The cleaner listing usually carries no timer word.

What does “delay start” mean on a pool cleaner listing?

“Delay start” is a seller's stated feature that describes a cleaner waiting a set period after it is placed in the pool before it begins. The actual delay time is on the maker's page.

How is an app schedule different from a built-in timer?

A built-in timer lives in the robot and starts the cycle on its own. An app schedule lives in the maker's application and lets you set run times from a phone. They are two different listing terms.

Where do you find the timer settings for a robotic cleaner?

Read the maker's manual for the model. It describes the timer, the delay, the cycle settings, and, for a cordless robot, how the charging dock and app schedule work.

Is a pump timer part of the pool cleaner?

No. A pump timer is pool equipment that controls the pump. For a suction-side cleaner, the pump timer controls when the cleaner runs. ENERGY STAR's pool pump page describes pump timers as a way to reduce filtration times.

Do you need a timer to run a suction cleaner?

A timer is not required to run a suction cleaner; it is a way to set when the cleaner runs. Many pool owners use the pump's existing timer. The pump manual and a pool professional are the sources for how to set it.
