Pool Cleaner Energy Consumption: How Much Power?

How pool cleaner types draw power

Pool cleaners fall into three main types based on how they receive power. Robotic cleaners are self-contained units that plug into a standard outlet and operate on low-voltage electricity. They do not rely on your pool pump or a booster pump. Suction-side cleaners attach to a skimmer or a dedicated suction line and are powered by the pool pump's water flow. Pressure-side cleaners use a booster pump that runs separately from the pool pump to push water through the cleaner. Each type's energy consumption reflects its power source.

Knowing which type you are considering helps you read the listing. Robotic cleaner listings typically mention a power cord and a low-voltage transformer, while suction-side and pressure-side listings often state that they connect to a pump or a booster pump. For a broader overview of cleaner types, see the pool cleaner types guide.

• Robotic: powered by low-voltage electricity from a wall outlet
• Suction-side: powered by the pool pump's suction flow
• Pressure-side: powered by a separate booster pump

Stated energy consumption figures

ENERGY STAR's page on pool pumps cites a PG&E study that measured the annual electricity use of different cleaner types. The study found that a robotic cleaner used 197 kWh per year, a cleaner powered by a filter pump used 1,675 kWh per year, and a booster-pump-powered cleaner used 2,989 kWh per year. These figures come from that specific study and are meant to illustrate the relative consumption, not to predict your pool's usage exactly.

A kilowatt-hour (kWh) is a unit of electricity. It represents the energy used by a 1,000-watt appliance over one hour, as the U.S. Energy Information Administration defines it. The study figures give you a starting point for comparing the three types, but your own usage will vary based on your pool size, pump runtime, and local conditions.

Because suction-side and pressure-side cleaners run off a pump, their energy consumption is tied to the pump's runtime and speed. The pump's own energy use is a separate factor; see the pool pump energy efficiency article for more on that topic.

What your operating cost depends on

The amount you pay for cleaning is determined largely by your electricity rate, measured in cents per kWh. To estimate your cost, multiply the annual kWh figure from the study by your local rate. Your utility company provides the rate for your area. This guide does not calculate or promise any savings or costs, because actual expenses depend on your specific pool and equipment.

It is also worth noting that the study's robotic cleaner figure is for the cleaner alone. Suction-side and pressure-side figures include the pump or booster pump energy used while the cleaner runs. If you already run a variable-speed pump for filtration, the added energy from a suction-side cleaner depends on how the pump's speed changes. You can discuss that with your pool professional or use the pump maker's sizing information.

Shopping considerations for energy-conscious buyers

When you shop for a cleaner, the energy consumption may matter less than how the cleaner fits your pool and filter setup. Robotic cleaners are mobile and can be used on inground and above ground pools, but they require a nearby outlet. Suction-side cleaners are often less expensive up front, but they add runtime to your pool pump. Pressure-side cleaners demand a booster pump, which is an additional piece of equipment and adds to the energy picture.

For an inground pool, a robotic cleaner often pairs well with an existing pump setup. For an above ground pool, a suction-side cleaner may be simpler because your pool pump already runs. You can compare robotic models in the Dreame cleaner guide or look at wall-climbing cleaners for inground pools.

Also consider the pump itself. If your pool uses a single-speed pump, a suction-side cleaner can add to the pump's already high energy use. A variable-speed pump can change that picture, as described in the variable speed pump guide.

For above ground pool owners, the above ground pump guide explains pumps that may power a suction-side cleaner. The inground pump guide offers a similar overview for inground setups.

How to read cleaner listings for power information

When reading a pool cleaner listing, look for power-related words. Robotic cleaners may list their rated voltage (for example, a low-voltage DC input) or the wattage of the unit. Suction-side and pressure-side cleaners may not list wattage because their energy use depends on the pump or booster pump they connect to. Instead, the listing will state whether the cleaner requires a dedicated suction line or a booster pump.

The stated power consumption figure for a robotic cleaner is usually in watts or kilowatts. You can use that figure with the study's annual kWh numbers to get a general sense of the cleaner's place in the energy comparison. However, the actual energy use over a season depends on how long you run the cleaner and how often you use it, so treat any single figure as an approximation.

For a deeper look at how cleaner and pump listings differ, see the cleaner pump connection article. That guide explains which cleaners run off the pool pump and which run independently.

What to pick for your situation

Questions

What is a kilowatt-hour (kWh)?

A kWh is a unit of electricity use. It is the energy consumed by a 1,000-watt device running for one hour. Your electricity bill is based on the number of kWh you use.

Which cleaner type used the least electricity in the study?

According to the PG&E study cited by ENERGY STAR, a robotic cleaner used 197 kWh per year, which was the lowest figure. The study's suction-side cleaner used 1,675 kWh per year and the pressure-side cleaner used 2,989 kWh per year.

Does a robotic cleaner require a booster pump?

No, a robotic cleaner is self-contained and draws low-voltage power from a regular outlet. It does not need a booster pump or rely on your pool pump.

How can you find your electricity rate to estimate your cost?

Your utility company publishes its rates, often on its website or on your monthly bill. Multiply the annual kWh figure you are comparing by your rate in cents per kWh to get an approximate annual operating cost.

Are the study figures the same for every pool?

No. The figures come from a specific study and reflect that study's conditions. Your actual usage depends on your pool size, pump runtime, cleaner type, how often you clean, and local factors like water temperature and debris load.

Can you compare the energy consumption of a suction-side cleaner to a robotic cleaner just by looking at wattage?

It is not straightforward. A suction-side cleaner's energy use is tied to the pool pump, which draws much more power than a robot's low-voltage system. The study's annual kWh figures are a better basis for comparison than a single wattage rating.
