Introduction
Vacuuming is one of the fundamental tasks in pool maintenance. Debris, leaves, sand and dirt accumulate on the bottom and walls, and the filtration system alone cannot remove them. This is where pool vacuums come in.
There are two main categories: manual vacuums, operated by you, and automatic vacuums, which work connected to the pool's hydraulic system. Each type has its advantages and ideal situations for use.
In Margem Sul, where we face specific challenges like sand from Costa de Caparica, pine needles from Aroeira, or olive leaves from Azeitão, choosing the right vacuum makes all the difference. This guide compares the two types to help you make the best choice.
Manual Vacuums
What They Are
Vacuums operated by you, connected to the pool filtration system through the skimmer or dedicated connection. You control the movement and area to vacuum.
Basic Components

Head Types
| Type | Feature | Best For |
|---|---|---|
| Triangular | Easy corners | Small pools |
| Rectangular | Wide coverage | Flat bottoms |
| Flexible | Adapts to curves | Irregular shapes |
| With wheels | Glides smoothly | Large areas |
| With brushes | Cleans and vacuums | Adhered dirt |
How to Use Correctly
Preparation:
| Step | Action |
|---|---|
| 1 | Check skimmer basket |
| 2 | Check filter (not dirty) |
| 3 | Assemble pole and head |

Automatic Hydraulic Vacuums
What They Are
Devices that move automatically around the pool, connected to the filtration system. There are two main types: suction and pressure.
Suction Vacuums
Connect to the skimmer or bottom drain, using the pump suction to move and vacuum.
How They Work:
- Pump suction pulls water
- Device moves randomly
- Dirt goes to filter
- Movement by membranes or turbines
| Feature | Value |
|---|---|
| Connection | Skimmer or bottom drain |
| Power | Pool pump |
| Movement | Random |
| Filtration | Pool filter |
| Price | €150-500 |
Popular Brands:
- Zodiac MX6/MX8
- Hayward Pool Vac
- Pentair Kreepy Krauly
Advantages:
- Moderate price
- Simple installation
- Automatic operation
- Few moving parts
Disadvantages:
- Overloads filter
- Random movement
- Can lose suction
- Doesn't clean walls well
Pressure Vacuums
Connect to the water return, using pressure to move. Some require a dedicated booster pump.
How They Work:
- Water pressure drives turbines
- Device moves across bottom
- Dirt collected in its own bag
- Doesn't overload main filter
| Feature | Value |
|---|---|
| Connection | Return or booster |
| Power | Water pressure |
| Movement | Systematic |
| Filtration | Own bag |
| Price | €300-800 |
Types:
| Type | Description | Price |
|---|---|---|
| Without booster | Uses existing pressure | €300-500 |
| With booster | Dedicated pump | €500-800 |
Popular Brands:
- Polaris 280/380
- Zodiac Polaris
- Hayward TriVac
Advantages:
- Doesn't overload filter
- More systematic movement
- Collects large debris
- Good coverage
Disadvantages:
- Higher price
- May require booster
- More complex installation
- More maintenance

Frequently Asked Questions
Can I use the manual vacuum every day?
You can, but it's usually not necessary. During heavy dirt periods, vacuuming 2-3 times a week is sufficient. In winter, once a week or fortnightly is enough.
Does the automatic vacuum completely replace the manual?
In most cases yes for the bottom. However, you may need manual intervention in corners, stairs, or for very localised dirt. Many owners have both.
Which lasts longer?
The manual, being simpler. A good manual vacuum can last 10-15 years. Hydraulic automatics typically last 5-10 years with proper maintenance.
Vacuum to filter or to waste?
For normal dirt, to filter ("filter" position). For heavy accumulation, algae, or treatments, to waste ("drain" or "waste" position) to avoid overloading the filter.
How many metres of hose do I need?
Pool length + distance to skimmer + 2-3 extra metres for manoeuvring. An 8m pool typically needs 10-12m of hose.
Can I leave the automatic running constantly?
Not recommended. 2-4 hours per day is sufficient. Continuous operation wears parts faster and can affect water circulation.
Does the automatic work with any pump?
Depends on the model. Check the recommended minimum and maximum flow rate. Variable speed pumps may need adjustment to ensure adequate suction/pressure.
Conclusion
The choice between manual and automatic vacuum depends on your needs:
Choose manual vacuum if:
- You have a small pool
- Limited budget
- Use pool occasionally
- Prefer total control
Choose suction vacuum if:
- You want to automate cleaning
- Have moderate budget
- Regular dirt without large debris
- Pool up to 70-80 m²
Choose pressure vacuum if:
- You have lots of surrounding vegetation
- Want to protect the filter
- Large pool
- Don't mind higher investment
For many owners in Margem Sul, the ideal combination is:
- Automatic vacuum for regular maintenance
- Manual vacuum for spot cleaning and difficult areas
