DOLPHIN Sigma Robotic Pool Cleaner with Bluetooth and Massive Top-Load Cartridge Filters, Ideal for Pools up to 50 Feet.

We received the item on time, in good condition, and it started working right away. The process of setting up and getting started took me 15 minutes When I ran it its first night, it did an incredible job of cleaning out my not-so-clean home Clearly the cable was not tangled in the pool due to its dirty state. (Note

) As far as getting above the waterline to scrub the walls, it does a great job. An impressive amount of suction and stability on the wall.

CAKE was the first thing cleaned to keep filters clean. It is great that there is an innovative load panel on top. IMPORTANT NOTE Please read the following carefully. It comes with 2 sets of filters, although it is not clear which are the smaller micron types. * Please note that the manual contains the following information It is klunky and incomplete to navigate through the digital manual via the iPhone app. The following is a marketing note There is a mention of two-stage filtering, but I am not sure how real that is. It seems like filter types can be swapped, but I can't see where a second stage would be, or how to stack them. There may be a disconnect with the part number / version. In the past few months, I have used my T4RC extremely to replace my recently deceased but The only reason I was reluctant to purchase this unit was the lack of feedback and information I could find to demonstrate its durability You can use either term. Obviously, we will have to wait a while before we can make any decisions. I will be experimenting with the daily automation routine this weekend to see how it works. * The Bluetooth remote control on my phone works SOMEWHAT better than the wonky one on my old T4RC* Update as of June 13 2018 Overall, the program seems to be working fairly well, but there is one notable I noticed the controller displayed the word "active clean" when on the automatic daily cycle, when it clearly was in the state of being in active clean mode at one point recently, but it wasn't I checked the app, and I see that the app is also indicating that the cleaning mode is active, but it has not moved. As soon as I switched on manual mode, it went into active cleaning mode in only its head. After I turned off manual control, it still indicated active cleaning mode. There's a big problem in the system, I think. The August 20 2018 update is as follows It's safe to say that after a few months, I no longer find the Aquabot T4RC to be as effective as it used to be. With Sigma, turtles are less noticeable, and it covers the pool faster than previously possible with superior tracking, yet it does not get the spots where the sloped wall meets the sloping floor at Even though you can get a lot of suction out of this unit, I think it doesn't seem to get out the crevasses like the Aquabot which had water jets to blow the dirt In 4 years, I haven't even used the pool brush outside of opening day. I'm anxious to get a chance to use it this summer, but even if it doesn't last, it still has good value potential. A problem still exists in indicating that your computer is in cleaning mode when it's not. A little annoying, but not a major issue.

Every time you do a cleaning cycle, it gets hung up on the main drain at least once. As if you were riding a turtle on your Tracks are on the sides and brushes are on the front and back, but no movement occurs in the central portion of the undermount system Robots that drive up on main drains will stop dead if they hit them This leads to it becoming stuck and not being able to escape. It can be released with a light tug on the cord, and it continues without any problem. The only problem is when the program is run unattended. The screen got stuck at the beginning of one cycle, and I didn't notice it until about halfway through the cycle. There are also devices that create a ramp (like a ring around the drain) and clips that create a dome over the The price for these options is only $50, they'll last for a few years, may be tricky to assemble, and the reviews are generally negative. Nevertheless, someone posted an interesting solution, which I have been attempting to extend. This means that the 1" PVC cap must be screwed on (with a stainless steel screw) Adding an 'internal dome' (washer) to the main drain cover is the best way to do this. Whenever the dome is climbed, at least one track or brush should contact the pool bottom, causing the dome to lose balance. The first time I tried, I used a shallow cap, which did not work. It would be better if I used a cap and tamper-proof tube The pipe can be considered an extension. By making it taller, it ought to be more effective. The following problems were associated with it Please note that the following information is sortable. By weighting myself down (weight vest and weights on a tool belt, mask, and shoes) I was able to stay on the bottom - snorkel - It was before For the screw, drill a hole. The wood spade bit was held by hand, and I worked it to make the hole start
Keeping one's feet on the ground while applying force to the ground Then use your screwdriver to drive in the screws. The hook of a garden claw was used to hook onto the main drain while working the tool with the other hand. Please note that the following information is sortable. It was an interesting experience. The task is definitely doable, though. Be sure you have someone spot you and extend a pole so you can grab onto it when you do It may also be If you know someone with scuba gear, ask them to help you. *2) The remote (bluetooth with smart phone) works, and I've used it to reach a couple of places the robot missed (especially after it gets stuck on the principal In response to action, it may be necessary to wait a couple of seconds for I have a poor reaction time and usually overreact On turns, compensate for the turn. You have to spend a lot of time in trying to get the thing going. This method works, but it isn't perfect. Sooner or later. The player is not permitted a After writing to the manufacturer, I did not hear back. Over time, I put the power supply in a patio box to keep it out of the weather, and I leave the robot in the water all the time, so not having a caddy hasn't been an issue. Inclusion of all- I am very pleased with the results. This is the cleanest the pool has ever been You're the best! There are a few pluses to it, too 4) It is completely self-sustaining A contained solution. 5) Filters need only to be cleaned every couple of weeks or so. The filters are very simple to clean, as they are on the top This page has been loaded and is in use The device can be easily removed. Once the garden hose has been cleaned, rinse it. This means there is no need to lay suction hose out and prime it.
7) Skimmer baskets do not become clogged, which results in a reduced vacuum pressure. *
8) When there is no debris in the filter, I need to backwash less often. The result is less water loss and less chemicals lost. **** 2 Month Update of *** ***
(#1 abv) stands out among my biggest complaints. In this case, it was the robot getting hung up in The robot probably has more problems than I was being fair to it, and I should clarify that it wasn't specific to this robot, because many people have similar problems with other robots as well. This is abv. It didn't solve the problem, so I tried another tall post, but that did not help either. It can climb on top of the post I bolted to the main drain cover, then balance itself perfectly as all track and brushes are suspended from it -- it was only *2" tall, but the robot could not resist. Affixed to the bottom but not in contact with it. it was designed to balance itself by having a handle. In any case, I considered modifying the bottom of the robot, but didn't want to damage The final solution I devised was to lower the main drain cover by building it out of a 10" wide x 1/2" thick HDPE cutting board (I bought it at Job Lot for $6). I have been using this solution for a week now, and it works flawlessly.

Although the Polaris cleaner did a respectable job, it was a bit dated and had a few cons that were rather bothersome. The first was that it would always seem to become stuck on our ladder in the deep end (despite having the guards in there). In the course of the cleaning process, we had to manually extract it several times from this location. In addition, the vacuum tended to miss a few areas we ignored or we manually vacuumed when the cycle was Our decision was to buy the Dolphin Sigma because it seemed to have a lot of modern features and bells and whistles that would simplify our lives. must admit that the pressure vacuum is more effective and faster in less time, and it requires less energy compared to the former. There are still two issues we need to resolve Today, instead of sticking to the ladder, we get stuck several times on the drain cap on the bottom of the shallow end and have to manually pull it out We cannot use any of the features when we aren't at home, so we can't use it when we aren't at home. In addition to missing several clean spots during the cleaning cycle, it also uses a pressure vacuum. Our last attempt at implementing a remote control feature failed. We can't make it work yet, but it should be able to solve this issue. The machine would have received five stars if it would have hit all the spots and would not have got stuck repeated times on a drain cap on the bottom, so I deducted a star for each of these problems. We had chosen an expensive option in the first place because we felt it was worth exploring.
