The below information is AI generated based on Australian websites information around this item. We have done our best to ensure its accuracy but suggest verifying any information within this tab before purchasing.
At a glance
The Ecovacs ULTRAMARINE P1 is a cordless robotic pool cleaner for households wanting automated cleaning across pool floors, walls and waterlines. It suits many in-ground pool surfaces and stands out for strong 18,200 LPH suction, dual-layer filtration and app scheduling. A key limitation is that runtime can vary by mode, so larger or dirtier pools may need more than one session.
What it’s great for
- Automated pool cleaning
- In-ground pool maintenance
- Fine debris pickup
- Wall and waterline scrubbing
- Scheduled cleaning
Where it works best
- Residential in-ground pools
- Concrete pools
- Vinyl pools
- Fibreglass pools
- Pebble pools
- Acrylic pools
Who it’s for
- Pool owners
- Busy households
- Homeowners wanting cordless cleaning
- Users needing app control
- Buyers with mixed debris conditions
Things to consider
It is designed for pools up to 600 m², and runtime is up to 3 hours in Eco mode, so very large pools or heavy-cleaning jobs may require multiple sessions compared with more specialised high-capacity models.
Lawn size suitability
Not applicable - this product is a robotic pool cleaner for pools up to 600 m², not a lawn mower.
Pet & child safety score
3/10 - not intended for lawn use; operates submerged in a pool environment rather than around pets or children on grass.
Smart home integration score
6/10 - app control and scheduling are included, but no supported voice assistant or wider smart home platform integration is specified.
Noise level vs category average
Quieter than many lawn robots in practical use, as it operates underwater rather than on open grass.
Complex garden handling
2/10 - not designed for gardens; its navigation and obstacle handling are built for pool floors, walls and drains.
Key benefits
- 18,200 lph suction: High suction power helps lift leaves, sand and common pool debris more effectively.
- Four synchronised roller brushes: Scrubs floors and walls to reduce manual brushing.
- Dual-layer filter: The 180 micron outer layer and 3 micron inner layer capture both larger debris and finer particles.
- Waterline cleaning: Reaches the waterline as well as floor and wall areas for more complete pool coverage.
- 5.5 cm obstacle crossing: Helps the cleaner get over raised sections and drains with fewer interruptions.
- Smartnavi path optimisation: Uses IMU-guided navigation to improve cleaning coverage and reduce missed areas.
- App control and scheduling: Lets you start cleans remotely and set single or multiple cleaning sessions.
- Up to 3 hours runtime: Supports extended cordless cleaning sessions in Eco mode before recharging.
Q: Can I control the ULTRAMARINE P1 when I'm away from home
A: No. ULTRAMARINE P1 uses Bluetooth app control, so commands and setup need you to be within Bluetooth range rather than logging in from anywhere. Scheduling still lets it run automatically once cleaning sessions have been set.
Q: Is this pool robot suitable for above-ground pools or in-ground only
A: It is positioned for in-ground pools, with coverage for pools up to 600 square metres and cleaning of floors, walls and waterlines. Above-ground pool compatibility is not listed, so this model is the clearer fit for in-ground installations.
Q: Will it clean pool steps, ledges and drain areas properly
A: It can move over raised sections and drains up to 5.5 cm, which helps in pools with small internal obstacles. It is not the right choice if your pool has tall entry steps or broad sun ledges that sit higher than that crossing height.
Q: How well does the filter handle fine dust and leaves
A: The dual-layer basket is designed to catch both large and fine debris, using a 180 micron outer layer and a 3 micron inner layer. That suits leaves and sand in the same clean, but the basket will fill faster after heavy leaf drop.
Q: Can it handle irregular pool shapes and still climb walls
A: Yes. SmartNavi path optimisation and IMU sensing are designed for varied pool shapes, with up to 99% floor coverage. It also scrubs walls and waterlines, but complex shelves or tight corners can still need occasional manual attention.
Q: How much cleaning can one charge cover in a large pool
A: ULTRAMARINE P1 runs for up to 3 hours in Eco mode, with shorter runtime in Standard and Max. That is useful for larger pools, but the higher suction settings trade battery time for stronger debris pickup.
