Owning a swimming pool is a luxury, but keeping it clean can be a time-consuming chore. That’s where robotic pool cleaners come in. These smart machines have revolutionized pool maintenance, saving homeowners countless hours of effort. However, with dozens of models on the market, selecting the right robotic pool cleaner can be confusing.

In this guide, we’ll help you understand what to look for when buying a robotic pool cleaner. Whether you’re buying for the first time or upgrading your current unit, these insights will help you make a smart decision.

Type of Pool (In-ground or Above-ground)

The first thing to consider is your pool type. Some robotic pool cleaners are specifically designed for in-ground pools, while others cater to above-ground pools. In-ground models tend to be more powerful and come with additional features such as wall climbing, whereas above-ground models are usually lighter and more budget-friendly.

Tip: Don’t use an in-ground cleaner for an above-ground pool unless the manufacturer specifically says it’s safe to do so.

Pool Size and Shape

Different pool cleaners have different capabilities in terms of range and coverage. If you have a large or irregularly shaped pool (kidney, L-shape, etc.), you’ll need a robotic cleaner with:

• Longer cable or cordless range
• Smart navigation (to avoid missing spots)
• Efficient route planning

Look at the specifications to find the maximum pool size the cleaner can handle. A robot designed for 30ft pools won’t perform well in a 50ft pool.

Corded vs. Cordless Design

Cordless robotic pool cleaners are gaining popularity due to their ease of use. You don’t have to worry about tangled cords or reaching power outlets. Most cordless models come with rechargeable lithium batteries that provide up to 90 minutes or more of runtime.

However, corded models tend to:

• Run longer
• Have more powerful suction
• Be better suited for larger pools

Verdict: If you prefer convenience and have a smaller pool, go cordless. If you want more power and long cleaning cycles, consider corded models.

Wall Climbing and Waterline Cleaning

Not all robotic cleaners can climb walls or clean the waterline. Some are designed for floor-only cleaning, while others can scrub walls and even the waterline, where oils and debris often accumulate.

Choose a wall-climbing model if:

• Your pool gets a lot of debris stuck to the sides
• You don’t want to manually brush the walls

High-end models offer powerful motors and traction wheels or caterpillar tracks to grip vertical surfaces easily.

Filter Type and Capacity

Robotic cleaners use internal filter baskets or cartridges to collect dirt, leaves, sand, and even algae. The quality and capacity of the filter matter more than you may think.

Look for:

• Fine or ultra-fine filters for dust and algae
• Large capacity baskets if you get lots of leaves
• Top-load design for easy removal and cleaning

Some models come with dual-layer filtration, separating large debris from finer particles. This helps maintain strong suction and reduces clogs.

Smart Navigation and Mapping

Older robotic pool cleaners moved randomly. But today’s advanced models use gyroscopes, sensors, and mapping technology to scan and clean pools systematically.

Smart navigation leads to:

• Faster cleaning times
• Less energy usage
• No missed spots

Features like auto-return to base and obstacle detection are great if you want a set-it-and-forget-it experience.

Suction Power and Brush System

Suction power directly affects how well the robot picks up debris. The stronger the suction, the cleaner your pool will be after each cycle.

But suction isn’t the only thing. The type of brush also plays a big role:

1. Rubber brushes are good for vinyl or delicate surfaces
2. PVC or combo brushes offer deeper scrubbing
3. Spinning or dual-brush systems enhance performance on algae and stuck debris

If your pool is prone to algae buildup or fine dust, go for a model with active brushing.

Cleaning Cycles and Timers

Some robotic pool cleaners offer multiple cycle options—quick clean, standard clean, or deep clean. Others allow scheduling through a timer or smartphone app.

Ask yourself:

• Do you want to clean daily or once a week?
• Would you prefer scheduled cleanings when you’re not at home?
• Do you want remote control or app integration?

Smart models allow customization of cleaning modes, and even notify you when the basket is full.

Energy Efficiency

Compared to traditional suction-side or pressure-side cleaners, robotic pool cleaners are more energy-efficient. They operate independently of your pool’s pump and filter system.

Check for:

• Low energy consumption (measured in watts)
• Eco-clean modes for reduced usage
• Automatic shut-off when the cycle is complete

Although robotic cleaners cost more upfront, their long-term energy savings are significant.

Durability and Warranty

Always check the build quality and the warranty offered. A longer warranty often means the manufacturer is confident in the product.

Look for:

• High-quality plastic housing (UV and chemical-resistant)
• Water-sealed motor and battery systems
• Easily replaceable parts

A warranty of 2–3 years is ideal. Make sure customer service is easily reachable in your region.

Final Thoughts

Buying a robotic pool cleaner isn’t just about convenience—it’s about making a smart investment that saves time, effort, and even money in the long run. Whether you have a small above-ground pool or a large luxury setup, the right robotic cleaner can make a world of difference.
