Dolphin Nautilus CC review

A Maytronics floor-and-wall robot built around servicing: the filter basket lifts out from the top, the body drains quickly for lifting, and the handles are where a wet machine is actually held.

The bottom line Designed by people who have emptied a filter basket. Top access, quick drainage and proper handles are the three things that decide whether a robot gets used after the first month, and this is the only machine here that leads with them. The listing is unusually thin on figures — no runtime at all — so it is bought on the servicing and on the maker rather than on a comparison table.

On the maker’s own page

A robot cleaning floors and walls, stated to work regardless of pool shape or surface, for flat-floored pools up to 10 m. Two active brushes remove dirt, algae, leaves and insects. Filtration is described as dual.

The filter basket is accessible from the top — open the lid, lift the basket, rinse it. The body releases water quickly for lifting out, with ergonomic handles. Made by Maytronics, with a stated two-year warranty.

The listing with no runtime

Every other robot in this family leads with a runtime in minutes. This one does not publish it at all.

That is a gap, and it is the gap that matters most on a cordless machine — so it is worth saying that this listing does not state whether this robot is cordless. What it states is climbing, brushing, basket access and lifting, and this page reports what was published rather than inferring the rest.

Why the basket access is the feature

The filter basket is emptied after every cycle, for as long as the robot is owned. A basket reached from underneath means turning a wet machine over on a lawn; a lid on the top means opening it where it sits.

It is not a specification and it is the thing that decides whether a robot is still in use in year three.

The limit, stated plainly

Flat-floored pools up to 10 m. Sloping floors are out and longer pools are out, and the maker says so rather than leaving it to be discovered.

Availability

The German, French, Italian and Spanish Amazon stores sat at roughly 679 € at the single check this page is built on.

The American Amazon store stocks it as well, in local currency, which the euro range above deliberately leaves aside.

The British Amazon catalogue holds the reference with no seller standing behind it.

Declared figures, and the gaps between them

Strengths

  • The filter basket is accessible from the top — lid off, basket out, rinse — which is the job done most often
  • Quick water release, which is the difference between lifting a robot and lifting a robot full of water
  • Two active brushes and stated wall climbing regardless of pool surface
  • Made by Maytronics, with a stated two-year warranty

Compromises

  • No runtime published, which is the headline figure on every other robot in this family
  • No filter fineness, no charge time and no weight published
  • Stated for flat-floored pools up to 10 m, which is a limit worth reading before ordering

The questions this one raises

Why is there no runtime?

The listing does not give one, and it is the only robot in this family without one. That is a fact about the listing rather than about the machine, and this page records it instead of estimating from the price or from other models in the range.

What does top-access actually change?

How often the basket gets emptied. A basket reached from underneath means turning a wet robot over; a lid on top means opening it where it stands. It is the maintenance job that happens after every cycle, and it is the one this machine is designed around.

What does “flat-floored pools up to 10 m” exclude?

Pools with a sloping floor, and pools longer than ten metres. The maker states it plainly, which is more than most of this shelf does about what defeats a machine.

Who this one is for

Somebody replacing a robot and choosing on servicing rather than on specification
