Best Pool Cleaners Under £500: Value Without Compromise
Your pool needs cleaning but your wallet says no to a £1,500 robot. Good news: you do not need to spend four figures for a clean pool. The Zodiac MX8 at £349 delivers solid automated cleaning for less than the cost of four professional pool cleans. And at the top of the under-£500 range, you are knocking on the door of entry-level robotic cleaners that will save you even more in the long run.
We tested 6 pool cleaners under £500 including robotic, suction-side and cordless models. The focus was on real cleaning results, not flashy features. Can it clear a week's worth of leaves and sand from a 10-metre pool in a single cycle? That is the only question that matters at this price point.

What We Like
X-Drive navigation with cyclonic suction covers the pool systematically rather than randomly bouncing
Flex Power turbine generates 30% more suction than previous Zodiac models
No electricity needed: runs off your existing pool pump, cutting energy costs to zero
Only 2 moving parts mean virtually zero maintenance and a long operational life
Watch Out For
Cleans floor and some wall areas only, does not reach the waterline
Relies on your pool pump running, which adds to pump wear and electricity costs indirectly
Suction-side cleaners are louder than robotic models because the pump runs throughout the cycle
Tom Bradshaw's Verdict
The Zodiac MX8 is the best suction-side cleaner for UK pools. If you already have a good pump and want the lowest purchase cost, it delivers solid floor cleaning for under £350. But a robotic cleaner will outperform it on walls and fine debris.
Suction cleaners only at this price. The Zodiac MX8 is the clear leader. Connects to your existing pump. Good for pools under 12 metres with moderate debris loads.
💰
£350 to £500
Entry-level cordless robots appear here. Limited battery life (60 to 90 minutes) and floor-only cleaning. Watch for the Dolphin E20 during Amazon sales, it occasionally drops to £499.
📈
Just Over £500
If you can stretch to £599 to £649, you unlock the WYBOT Osprey 700 (cordless) and Dolphin E20 (corded robotic). Both are significant upgrades over anything under £500.
Pro tip: Set price alerts on Amazon for the Dolphin E20. It drops below £500 during Prime Day (July) and Black Friday (November) nearly every year. At that price, it is the best value pool cleaner available in the UK.
The Zodiac MX8 at £349 is the best pool cleaner under £500. It is a suction-side cleaner with X-Drive navigation and Flex Power turbine that delivers systematic coverage on floors and partial walls. For a robotic model, the Dolphin E20 sometimes drops below £500 during seasonal sales on Amazon.
QIs a cheap pool cleaner worth buying?
It depends on the type. A £349 suction cleaner like the Zodiac MX8 is excellent value and will last 3 to 5 years. Avoid generic no-brand robots under £200 on Amazon, as they typically have weak suction, poor navigation and no warranty support in the UK. The sweet spot for budget robotic cleaners is £450 to £650.
QSuction or robotic cleaner on a budget?
Under £500, a suction cleaner gives you better cleaning performance per pound. The Zodiac MX8 at £349 cleans floors and partial walls. The cheapest reliable robotic cleaner is the Dolphin E20 at £649. If you can stretch your budget by £150, the robot is worth it for the energy savings and convenience.
QDo I need to run my pump while using a suction cleaner?
Yes. Suction-side cleaners like the Zodiac MX8 connect to your pool skimmer and rely on your pump for suction power. Your pump must run throughout the cleaning cycle (3 to 4 hours). This adds to electricity costs and pump wear compared to a robotic cleaner that runs independently.
