Maytronics Dolphin X20: two-month filter and cable notes for Dolphin S200 buyers

After two months, my Dolphin X20 cleans much like my old robot, but its cable tangles less. I also tried a cheaper fine filter in my leafy 6 × 9 m pool.

A Dolphin X20 robotic pool cleaner resting on tiled ground with its blue power cord attached and a filter basket set behind it.
Two white and black pool cleaner filter baskets with carry handles placed side-by-side on an outdoor stone ledge, comparing a fine pleated filter paper basket on the left with a mesh filter basket on the right.
Two white pool-cleaner filter baskets are open on outdoor paving, with a standard dark mesh filter basket above and a pleated filter basket below; part of the cleaner is visible at upper right.

Three years ago I bought the Bunnings pool robot that cost A$1,499. It worked quite well, and I used it about once a week on average. I always took it out and cleaned it after use and never left it in the pool overnight, but even so, it failed just as other reviews said it would: after the warranty expired.

This time I decided to try a world-famous brand and see whether it would last longer. The official website price was A$1,599; some pool-equipment dealers were slightly cheaper, and there was a Xiaohongshu listing at A$1,299 plus shipping. I eventually bought it locally for a little over A$1,400. This brand does not leave much room for price negotiation.

I have used it for two months, and its results are about the same as the A$1,499 Bunnings model. The model I bought is the X20. It can climb the walls but cannot clean the waterline, although I do not think that makes much difference. I really did not want to spend more on a higher-end model in case it still failed after the warranty expired.

I also bought a finer paper filter from 1688. I have to say that it is practically identical to the original. I could not be happier with it.

One more thing: compared with the Bunnings model, its cable is less likely to tangle. My pool is 6 × 9 m and has a lot of fallen leaves, for reference.

Before You Buy

Models in your region

The owner identifies the product as a wired Dolphin X20 bought in Australia but does not provide the full model number. The Australian official page identifies the regional X20 as model 99996114-AUWT with floor and wall brushing; related US and French S200 versions are separate corded models, not confirmed regional renames.

Maytronics Dolphin X20 Maytronics Dolphin X20 99996114-AUWT (Australia) The official Australian page identifies X20 model 99996114-AUWT as a wired Dolphin with active floor and wall brushing. The owner does not give a full model number, and reports that this X20 does not clean the waterline; the page’s general waterline wording conflicts with that experience, so confirm coverage for the exact unit offered.
Maytronics Dolphin X20 Maytronics Dolphin S200 99996202-USW (US) The US Dolphin S200 is a separate corded model from the X20 reviewed here. The US S200 lists floor, wall and waterline coverage, a 50-foot maximum pool length, a two-hour default cycle, fine filtration plus an additional ultra-fine kit, a weekly timer, an anti-tangle swivel and no app. These specifications do not prove equivalence to the owner’s X20.
Maytronics Dolphin X20 Maytronics Dolphin S200 99996202 (France) The official French evidence is for the separate same-brand corded Dolphin S200, included for comparison rather than as an official regional rename of the owner’s X20. French specifications list pools up to 12 m, a two-hour cleaning cycle, floor, wall and waterline coverage, and fine and ultra-fine filtration. These specifications should not be transferred to the owner’s X20.

Maytronics Dolphin S200 99996202 (France)
What to know
The official French evidence is for the separate same-brand corded Dolphin S200, included for comparison rather than as an official regional rename of the owner’s X20. French specifications list pools up to 12 m, a two-hour cleaning cycle, floor, wall and waterline coverage, and fine and ultra-fine filtration. These specifications should not be transferred to the owner’s X20.

Cleaning coverage and model uncertainty

The owner's two-month result was broadly comparable with the previous A$1,499 Bunnings robot, and the owner specifically reports wall climbing but no waterline cleaning. The Australian X20 page confirms active floor and wall brushing, but its generic PowerStream text also mentions waterline cleaning, so buyers should verify the exact local version rather than assume that feature from the product-family name.

The US and French S200 listings explicitly include waterline coverage, but those are separate regional models. Their specifications show why the S200 should be treated as a comparison option rather than evidence that every X20 has the same cleaning scope.

Cable behaviour in a large, leafy pool

For the owner's 6 × 9 m pool with many fallen leaves, the X20 cable was less prone to tangling than the previous Bunnings robot's cable. This is a personal comparison, not a measured cable test or a claim that every installation will behave identically.

The Australian X20 is officially described as a wired Dolphin, which matches the owner's cable-based setup. Buyers should still consider their own pool layout and debris load; the X20’s maximum pool length remains unconfirmed.

Filters, price and the warranty trade-off

The owner paid a little over A$1,400 locally after seeing an official A$1,599 price and a third-party A$1,299 listing plus shipping. These are the owner's purchase-price observations from Australia, not a current price recommendation or a verified market average.

The owner bought a finer paper filter through 1688 and found it practically identical to the original. That is a personal compatibility observation, not manufacturer approval; the official S200 pages' fine and ultra-fine filter details do not prove that this third-party filter fits the X20 or that the models share filter parts.

The owner chose not to pay more for a higher-end model because of concern that it might still fail after the warranty expired. The account covers two months of X20 use, so it cannot establish long-term reliability or confirm whether the robot will outlast the previous unit.
