Suction, pressure or robotic? The pool cleaner aisle is confusing on purpose. The honest answer is that most Cape Town pools are best served by the cheapest category, and the expensive ones solve problems many owners do not have.
Suction pool cleaners: how they work and who they suit
A suction pool cleaner plugs into the weir or a dedicated suction point and is driven by your existing pump. It crawls the floor and walls, sending debris to the pump basket and filter. There is no separate motor, which is exactly why it is the most common cleaner in South Africa: nothing to burn out, cheap to replace, and any pool shop stocks the parts.
The trade-off is that it loads your filter with everything it picks up, and it relies on your pump being healthy. A tired pump makes a suction cleaner look faulty when the cleaner is fine.
Automatic suction pool cleaner vs manual pool cleaners
An automatic suction cleaner maintains a pool that is already clean. A manual vacuum clears a pool that is not. They are different tools and neither replaces the other. If your pool has gone green or has a floor full of sand and leaves, the manual vacuum will do in twenty minutes what an automatic cleaner will fail to do all week.
Pressure and robotic pool cleaners: worth the money?
Pressure cleaners bag their own debris, which spares your filter, but many need a booster pump and that is real electricity every day. Robotic cleaners run independently of your plumbing and clean genuinely well, but they are the most expensive to buy and to repair. On a standard domestic pool with a working filter, neither is necessary. On a very large pool, or one under heavy leaf load, a robot starts to make sense.
Why your pool cleaner stops working
Most cleaner complaints are not cleaner faults. In order of how often we find them: a blinded or matted filter bed, a cracked weir basket letting debris through, a worn pump impeller, an air leak on the suction line, and only then the cleaner itself. Before replacing a cleaner, have the circulation checked. More on that in pool pump faults and sand filters explained.
Pool cleaners: frequently asked questions
How does a suction pool cleaner work?
It connects to the weir or a dedicated suction point and is powered entirely by your pool pump. Water drawn through the cleaner moves it around the pool and carries debris to the pump basket and filter. There is no separate motor.
Which is better, a suction pool cleaner or an automatic pool cleaner?
An automatic suction cleaner is the everyday choice for a domestic pool that is already clean. A manual vacuum is far better for clearing a dirty or green pool. Most owners are best served by owning both.
Why is my suction pool cleaner not moving?
Usually a circulation problem rather than a cleaner problem. Check for a blocked or matted filter, a cracked weir basket, a blocked hose, or an air leak on the suction line before you replace the cleaner.
Do I still need to vacuum with an automatic pool cleaner?
Yes, occasionally. Automatic cleaners miss steps, corners and heavy debris after a storm. A manual vacuum remains the fastest way to recover a pool.
Are robotic pool cleaners worth it in South Africa?
On a large pool or one under heavy leaf load, yes, because they clean independently of your filter and plumbing. On a standard pool with healthy circulation, the extra cost is hard to justify.
Does a suction pool cleaner damage a fibreglass pool?
A well-maintained one does not. Worn hard parts and dragging hoses can mark a gelcoat over time, so replace perished feet and diaphragms rather than running a cleaner to destruction.
Get the circulation checked before you buy a new cleaner
We see clients replace a perfectly good cleaner when the actual fault was a filter that stopped filtering months earlier. See pool vacuum cleaners in South Africa or book a check on our pool pump repairs page.
