Pool Coverage

The Dolphin T15 robotic pool cleaner exhibits an impressive cleaning coverage that's hard to ignore. This versatile gadget effectively cleans floors, efficiently scrubbing away all stubborn dirt and debris that may be present. Its thorough nature doesn't stop at that, though, as it extends to pool walls with commendable agility.

This diligent pool assistant doesn't skimp on the waterline either. It ensures the entire pool is sparkling by maintaining a rigorous scrub on the pool's waterline, leaving no grime untouched.

What's more, the Dolphin T15 is not limited to flat pools. It exhibits a flexible cleaning approach accommodating different pool shapes and sizes. Hence, you can count on its effective pool cleaning regardless of your pool's design. It promises an all-rounded, deep clean no matter the pool configuration.

Filtration

The ProLine robotic pool cleaners, with their NanoFiltration ability, undeniably delivered a significantly better cleaning performance than any other robot I've come across. My first-hand experience can attest to this. This advanced feature, in a nutshell, is a game-changer in the realm of robotic pool cleaning.
Known to have the capacity to filter debris as small as 2 microns, the NanoFiltration function has taken this pool cleaning robot way ahead of most of its competitors. I saw the ProLine robot filter out tiny particles, so minuscule that you wouldn’t even know they were lurking in your pool. Its filtration ability truly goes much deeper, offering you a cleaner, clearer, and healthier pool.
The precision at which this NanoFiltration function operates is impressive. It not only removes larger debris like leaves but can even get rid of algae, pollens, and bacteria efficiently. This latter feature makes your pool safe from harmful microscopic organisms that could otherwise harm your health or disrupt your swimming experience.
In my experience with testing pool cleaning robots, none have come close to matching the depth of cleaning the ProLine robot provides. The pristine condition it left my pool in was nothing short of amazing. Its superior NanoFiltration technology makes it a worthwhile investment for any pool owner.

Cleaning Performance

The Dolphin ProLine showed exemplary results in our test pools. Its powerful twin brushes scooped up both small and large debris effectively, making cleaning a swift and effortless process. The ProLine's self-programming mode and three programmable schedules catered to all our cleaning needs. The weekly timer option allowed for consistent maintenance without constant supervision.
On the other hand, the robotic cleaner from Dolphin Max-Series, especially the Dolphin Premier, excelled in different aspects. Its exceptional dual-filtration system tackled fine and rough particles quite well. Additionally, the highlight of the Premier was its smart navigation system which ensured thorough coverage of the entire pool area.
The Sigma from the Dolphin Max-Series, showcased impressive climbing ability in the pool walls and stairs. And while the Quantum provided a less compelling climb, its superior suction mechanism and advanced mapping technology more than made up for it.
Both Cayman and Escape models exhibited compelling performances on a par with the rest of the Max-Series, with convenient features like automatic shut-off and user-friendly remote controls that made pool cleaning quite effortless.
While the Dolphin Explorer didn't perform quite as impressively, its affordable price point and commendable cleaning efficiency still make it a worthy contender among robotic pool cleaners. Its systematic pattern scanning and swift coverage were particularly notable.
Providing remarkable value, the Aquabot pool cleaner stood out in our testing with its superior cleaning ability despite its low price. It astounded us with its efficient scrubbing and suctioning capabilities that effectively removed various types of debris from the pool. It's safe to say this little device punches way above its weight.

Restocking Fee

Cordless

True to my preference and following the extensive tests conducted on over a hundred robotic pool cleaner models, I am inclined towards corded pool cleaners. Corded robots are, in my experience, more reliable for constant power supply, thereby delivering consistent performance throughout the cleaning cycle. They don't require a break in their routine to recharge, a quality that has invariably placed them higher in my ranking scale.
In comparison, cordless robots, though seemingly convenient and futuristic, fall short in certain areas. They undeniably require multiple interactions per day and need to be recharged after every cleaning cycle. This means you would need to keep an eye on them regularly, cancelling out the supposed 'convenience' they offer.
Moreover, I found that cordless robots do not meet the same level of power as their corded counterparts. This has an immediate effect on their cleaning prowess - something evident in their performance. Also, the fact they usually do not last as long is further discouragement, especially when considering the long term usage.
As an owner of robotic pool cleaner, your goal is simplification and automation of your pool maintenance. Despite the initial charm of cordless robots, they become more demanding over time, an experience you wouldn't have with corded types that offer maximum automation, such as the cherished weekly timer feature. Therefore, in the battle between corded and cordless, corded pool robots clinch the win for me.

Weekly Timer

The benefits of a weekly timer on a robotic pool cleaner cannot be overstated. This function allows for optimal automation, maintaining your pool clean without daily interaction. The convenience a weekly timer brings is simply immense; imagine setting up your robotic cleaner and then forgetting it for a week, only to find your pool sparkling clean every time.
Unfortunately, not all robotic pool cleaners come with this exceptional feature. A robotic cleaner without a weekly timer isn't necessarily a deal-breaker, but it does require a bit more effort on your part to ensure a clean pool. It's one of those facets where once you experience the convenience, returning to a manual setup feels like a chore.
Whether we look at my preferred Dolphin ProLine or the Aquabot, the inclusion of a weekly timer is always a significant plus point. The weekly timer, combined with other cutting-edge features, elevates the pool maintenance experience to an entirely new level.
All in all, the essence of a robotic pool cleaner lies in its autonomous operation, and a weekly timer essentially epitomizes that. Therefore, in my opinion, all robotic pool cleaners should indeed be equipped with this feature.
