Dolphin Proteus DX4 Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Waterline Scrubber Brush, Ideal for In-Ground Pool up to 50 FT in Length

This is a newer version of the first dolphin we purchased 7 years ago. We use it everday from mid May to mid September.It dies a frea job cleaning the bottom and sides of our inground pool. It is such a pleasure not having to clean the pool ourselves. On occasion, we will see a spot missed in the pool corner. We just brush it away from the corner and the next day the dolphin cleans it.

I have owned this pool vacuum since 2021. It was recommended to me by my pool guy/neighbor. I have kept care of it, emptying and cleaning the tracks out myself. And it works wonderful! That is really difficult in my pool because not only do we have a lot of dirt and plants blowing in (pepper trees with tiny leaves) but we also have ducks using our pool twice a year flying south and north (truly not our idea).Customer Service is also great. I recently was having problems (first time in 4 years) and requested service instructions. They responded within 24 hours with suggestions to fix and with full instructions to mail off unit. I did not have to mail it because their suggestions worked and the vacuum is happily cleaning again.

We have a big pool so it doesn't get to all areas, 20 x 40 but the basket is so easy to clean. Also it's lightweight and the cord has a swivel. So helpful to not tangle. Great looking.

Been wanting a Dolphin but their higher end line $2000 price tag was too high for my little 15’x24’ kidney shaped pool. Saw their little Proteus for $680 and thought I would give it a try. Unboxed, threw in the pool, plugged in and hit start. 2 hours later my pool was mostly clean. Ran it for another cycle and it was clean. Only have to run it about once or twice a week now. The little basket filter catches everything even silt. I didn’t buy the caddy. Seems like a wasteful add on. I just park it on top of a short 2x4 on my back porch to keep the cleaning bristles off the ground so they dont warp. Overall I would recommend this robot. I have had for a month and so far it is a good value.

I purchased the Proteus DX4 robotic vacuum for one week ago. I have probably ran it ten times. Today I observed the performance for the entire 2 hours. The pool is 30’ X 18’ and kidney shaped. The circumference of the pool is 85’. I ran the DX4 for the default 2 hours. The pools pump is a variable speed and was running at about 1/3 maximum speed. I started the cleaning at the remote end of the pool in the shallow area. I have started the DX4 in different areas and get similar results. The DX4 climbed the wall 15 times in 6 areas which covered 25 feet or 30% of the pool circumference for water edge scrubbing. This seems disappointing, especially only scrubbing in six areas, 30% of the pool. The DX4 spent over 1/6th of the time around the main drain cover. It would back up and continue running over the drain cover. The main drain is shut off and not used in this pool. The main drain cover meets the new standards to prevent personal injury when the suction is turned on. The DX4 seems to prefer using the center of the length of the pool and only branching right or left in the six areas identified for water edge cleaning. Numerous times while climbing from the deep end (about 6’ deep) it would seemingly stall and abort the climb to the shallow end. I also observed it frequently moving forward and backward repeatedly only covering about a foot in either direction.Attached is a picture showing the six areas where water edge scrubbing was observed. The areas where there are no black buckets indicates there were no attempts for water edge cleaning or cleaning the pool floor.From my perspective the coverage for my pool was poor. I purchased the DX4 for the Water Edge Scrubbing and the Swivel in the power cord. Neither feature met my expectations. I expected the DX4 to cover the entire pool in the 2 hour cycle. I contacted Maytronics about my concerns last week, and the rep suggested I clean the impeller. The pool is screened and was manually cleaned before using the DX4, so I was confident there were no obstructions and the DX4 was clean after disassembling and inspection. I have also completely unplugged the unit, thinking the unit might reset, but the coverage characteristics are similar on the next run. Maytronics is willing to run diagnostics since the DX4 is within warranty period, only one week old, but I have to pay for shipping which seems ridicules.I contacted Maytronics support and their recommendations were (1) turn off the pool pump during the 2 hour cleaning period (2) The also felt the issue with continuous cleaning of the main drain was also tied to the pool pump (note the drain has a plug in it) (3) Be prepared to manually clean areas of the pool (4) DX4 will not clean steps because the water is too shallow (it has cleaned this area on a subsequent test run)I also ex[plained that I also tested a Maytronics Active Solo, which did not exhibit any of these issues and that it did an excellent job of cleaning the pool.I am a retired engineer. I have no experience in robotics.

This is a replacement for a rechargeable cleaner that I kept for 5 days and was not impressed. The DX4 does the job on the bottom and side walla. Highly recommended this pool cleaner.

My pool maintenance service recommended this product and I am so pleased they did. Suggest watching the YouTube video for this cleaner which convinced me to press add to order.

I purchased this unit 6 months ago. It started acting up, starting and stopping a few weeks ago. It finally would not start.I reported it to Maytronics on Monday and have yet to hear back from them. I also tried calling and was on hold for a long time. They did respond with:Thank you for contacting us.Your inquiry has been submitted and one of our Customer Care representatives will contact you as soon as possible in order to answer your question or resolve your issue.Your case number is: 01657220I have yet to hear from them. This is not right........... We really need to run the robot.
