Nobody buys a pool to spend their weekends cleaning it
Owning a pool should be about lazy Sunday swims, children splashing after school and quiet evening dips. It shouldn’t be about hours with a brush and a long pole. Yet keeping the floor and walls clean is one of the jobs that comes with the territory.
That’s where robotic pool cleaners come in. These clever little machines crawl around the pool on their own, picking up dirt and debris while you get on with your day. More and more of our customers ask about them, and for good reason.
In this guide we’ll explain how they work, what they’re good at, where they fall short and how to decide if one is right for you. We’ll keep it simple and honest, so you can make a choice that suits your pool and your lifestyle.
A robotic cleaner is a small, self-contained cleaning machine
A robotic cleaner is a compact unit that sits on the floor of your pool. It has its own motor, its own drive system and its own filter. You lower it into the water, switch it on and let it get to work.
How it moves
Most models drive on tracks or wheels. They follow a cleaning pattern across the floor, and many can climb the walls too. Some reach right up to the waterline. Built-in sensors or programmed routines help the unit turn when it reaches a wall, so it covers the pool in a methodical way.
How it cleans
As it moves, brushes loosen dirt from the surface. A pump inside the unit sucks water in through the base. That water passes through a filter basket or bag inside the cleaner, which traps leaves, sand, hair, insects and fine grit. Clean water flows back out into the pool.
How it’s powered
A low voltage cable runs from a power supply at the poolside to the cleaner in the water. The power supply plugs into a suitable outdoor socket. Always follow the manufacturer’s safety instructions, keep the power supply away from splashes and never swim while the cleaner is running.
How robotic pool cleaners compare with other options
There are a few ways to keep a pool floor clean. It helps to understand the differences before you choose.
Manual cleaning
This is the traditional way. You attach a vacuum head to a long pole and hose, connect it to the pool’s suction line and work your way around. It does the job, but it takes time and a bit of patience.
Suction and pressure cleaners
These cleaners connect to your pool’s circulation system. They move around using the flow of water from the pump. They can work well, but everything they collect goes into the pool’s main filter or a separate bag, and they rely on the pump running.
Robotic cleaners
A robotic unit works independently of the pool’s pump and filter. Because it filters debris itself, less dirt reaches your main filtration system. That can mean your main filter needs cleaning a little less often. Many people also find robots do a more thorough job on walls and steps.
If you’d like to understand what your main filter actually does, our guide to pool filtration explains it in plain English.
The benefits that make owners fall in love with them
Ask anyone who owns one and they’ll usually tell you they’d never go back. Here’s why robotic pool cleaners have won so many fans.
Time back in your week
This is the big one. Put the cleaner in, switch it on, and walk away. Many models finish a cycle in a few hours and switch themselves off.
A cleaner pool, more often
Because it’s so easy, you’ll probably clean more often. Little and often keeps the pool looking its best and stops debris from building up.
Less strain on the main filter
The cleaner catches much of the dirt in its own basket. That means less work for your main filter and less frequent backwashing or cartridge cleaning.
Better water circulation
As the cleaner moves, it stirs up water in corners and on the floor. That helps sanitiser reach the spots where circulation can be weaker.
Handy smart features
Depending on the model, you might find:
- Timers and scheduling, so it runs on set days.
- Remote or app control, to steer it to a problem spot.
- Filter full indicators, which tell you when to empty the basket.
- Floor only or floor and wall modes, for quicker or deeper cleans.
- Lift systems, which make it easier to take out of the water.
What robotic pool cleaners can’t do
They’re brilliant, but they’re not magic. Knowing their limits helps you set realistic expectations.
They don’t replace water care
A robot cleans surfaces. It doesn’t test or balance your water. You’ll still need to check sanitiser and pH levels and look after the water chemistry. Our swimming pool maintenance guide covers the full routine.
They can’t clean under a closed cover
Most covers need to be fully open while a robot runs. The cleaner also can’t reach inside a cover box or pit. If you have one, our guide to automatic pool covers explains how covers and cleaning fit together.
They don’t like big debris
Large stones, sticks or piles of wet leaves can block the intake or jam the brushes. Scoop out anything big with a net first.
They still need looking after
You’ll need to empty and rinse the filter basket after each cycle. Brushes and tracks wear over time and may need replacing. It’s a few minutes of work, but it matters.
The skimmer basket still needs emptying
Your pool’s own skimmer and pump basket will still catch debris from the surface. Keep emptying them, and backwash or clean your main filter as usual.
British gardens give a cleaner plenty to do
Pools in the UK face a particular mix of challenges. We have lots of mature trees, plenty of wind and rain, and long seasons when leaves, blossom and seeds seem to fall every day. All of that ends up on the pool floor sooner or later.
Autumn leaves and spring blossom
Leaf fall is the time most owners are grateful for help. A robot can keep on top of the small, soggy leaves that sink and stain. Just remember to net out the larger drifts first so the intake doesn’t clog.
Fine dust and pollen
Summer brings a surprising amount of fine material. Pollen, dust and grass cuttings drift in and settle. Many robotic pool cleaners have fine filter options designed to catch this kind of debris, which can help keep the water looking sparkling.
Busy family pools
Children bring sand, grass and all sorts of treasures into the water. A quick run after a busy afternoon resets the pool for the next day, without anyone having to pick up a brush.
Indoor pools
Indoor pools see less debris, but the floor still collects hair, dust and skin cells. A regular robot run keeps the surface fresh and helps the water circulate evenly.
Getting the best from a robotic cleaner
A few good habits will help your cleaner work well and last longer.
Before you start
Most problems with robotic pool cleaners come from skipping these simple steps.
- Open the cover fully.
- Net out large leaves and any stones or sticks.
- Check the filter basket is clean and fitted properly.
- Make sure the cable is untangled and long enough to reach the far end.
- Make sure nobody is in the water.
After each cycle
- Switch off at the power supply.
- Lift the cleaner out using the handle or cable. Let the water drain before lifting it fully.
- Empty and rinse the filter basket.
- Check the brushes for trapped hair or debris.
- Store it in the shade, out of direct sun.
Look after the cable
Tangled cables are one of the most common issues. Straighten the cable from time to time and avoid coiling it tightly. Some models have a swivel to reduce twisting.
When things don’t go to plan
- It keeps getting stuck. Check for obstacles such as a step edge, a drain cover or a large leaf.
- It isn’t climbing the walls. A full or clogged filter often stops it climbing. Empty and rinse it, then try again.
- The cable is twisting. Lay it out straight in the sun for a while and let it relax.
- It stops early. Check the power supply and plug. If it keeps happening, speak to the supplier or ask us for help.
Store it well over winter
If your pool is closed for winter, clean the unit, let it dry and store it somewhere frost free. Don’t leave it in the pool when the water gets very cold unless the manufacturer says that’s fine.
A note on chemicals
If you’re adding chemicals to rebalance the water, take the cleaner out first and let the water settle before it goes back in. Follow the label, wear gloves and eye protection, never mix chemicals, and always add chemical to water, never water to chemical. Keep swimmers out until the water is balanced, and store chemicals safely away from children and pets.
So, are robotic pool cleaners worth it?
For most pool owners, we think the answer is yes. They save time, keep the pool cleaner and take some of the load off your main filter. They’re especially useful if you’re busy, if your garden has lots of trees nearby or if you simply want to spend more time swimming and less time cleaning.
They’re a less obvious choice if your pool is very small and easy to reach with a brush, or if you genuinely enjoy the ritual of cleaning by hand. Some people do.
Questions to ask before choosing one
- Does it suit the shape and surface of my pool? Steps, benches and curves all matter.
- Does it clean walls and the waterline, or just the floor?
- Is the cable long enough for my pool?
- How easy is the filter to empty?
- What servicing and spare parts are available?
- Will it work with my cover and equipment?

Robotic cleaner questions we get asked a lot
How often should I run it?
Many owners run it two or three times a week in the swimming season, and more often after storms or heavy leaf fall. You’ll soon find a rhythm that suits your garden.
Can I leave it in the pool all the time?
It’s generally best to take it out after each cycle. That protects the cable and brushes and keeps it out of the way of swimmers.
Will it damage my pool surface?
A cleaner designed for your type of pool should be gentle on the surface. Check the manufacturer’s guidance and ask us if you’re unsure.
Does it clean the steps?
Some models manage steps well, while others struggle with them. You may still need a quick brush on the steps now and then.
Can I swim while it’s running?
No. Always take it out or switch it off before anyone gets in.
