Using HyperGrip rubber tracks, it firmly holds on to the surface of swimming pools as it cleans, while a front active scrubbing brush works to dislodge dirt and grime from pool floors and walls. The DX5i has a powerful motor that can circulate up to 5,000 gallons of pool water in an hour. And while at it, a double filtration mechanism involving a top-loader filter basket with two levels of filtration traps both large and tiny debris particles. You don't have to tip the cleaner upside down to clean it because there's top access to the filter basket. This Dolphin pool cleaner features the PowerStream technology which ensures superior wall climbing ability, it shoots out high-pressure jets of water in different directions to ensure it maintains a firm grip as it cleans the floor, walls, and waterline. For accurate navigation and better cleaning performance, the Dolphin Proteus DX5i is equipped with a 20-minute mapping system that captures the entire layout of swimming pools, enabling the robot to follow the most efficient cleaning route to save time and energy. As this robotic pool cleaner cleans, a 60-feet long anti-tangle swivel power cord keeps it going smoothly while making complimentary twists and rotations, without tangling. The Dolphin Proteus DX5i robotic pool cleaner has two cleaning cycles which last for 1 or 2 hours; the Quick Cleaning mode is for a much faster clean, while the Standard mode is for deep and thorough cleaning of swimming pool surface, including waterline cleaning, the cleaning cycles takes about 2 hours. The one-hour cleaning cycle is ideal for a quick clean, particularly on the floor and cove. Performance This Dolphin pool robot is designed to take off the daily and weekly maintenance of your swimming pool while you focus on the more important stuff, and it delivers on that end. The rubber tracks have excellent grip on all pool types to pool surfaces, from gunite to tile, vinyl lined pools, fiberglass, and more. The active brush roll will scrub and clean pool floors, walls, and waterline. And with an extra-large top load filtration system, the Dolphin Proteus DX5i is able to capture all sorts of pool rubbish, from floating debris to find dirt particles, small stones, and everything in between, leaving you with a dirt-free pool. Although this is generally a great robotic pool cleaner, it does have a few drawbacks. Furthermore, it comes with HyperGrip tracks, a front high speed scrubber, and shoots high-pressure jets backward to keep it afloat for waterline scrubbing. It also doesn’t clean pool steps, so you will have to manually brush them out yourself, so the robot does the rest including the waterline. Save for these few limitations, the Dolphin DX5i robotic pool cleaner is a very useful machine and does a great pool cleaning job. Ease of set up and use Like most Dolphin robotic pool cleaners, the Proteus DX5i is very easy to set up and use. It’s simply a plug-and-play device; once it's connected to a power supply, drop it into the swimming pool and let it go. The first 20 minutes it spends in the pool is used to scan for accurate navigation to make sure it follows the shorter route for a faster cleaning time. The Dx5i robotic pool cleaner can be connected to the MyDolphin smartphone app either via Bluetooth or WiFi and with this, you can easily and conveniently control your robotic pool cleaner from your hand as a remote control. From the app, you can choose between the quick or standard cleaning time or instruct the machine to spot clean. Reliability It’s important to consider the durability and probable lifespan of any robotic pool cleaner before purchase. Maytronics is one of the leading pool cleaner brands in the home robotics industry, and their gadgets are usually of standard quality and tend to have a decent lifespan. They may not be the cheapest pool cleaner you’ll find, but they are certainly very reliable and are always backed by a warranty. The Dolphin Proteus DX5i comes with a 2-year warranty. DX5i uses CleverClean Technology, Maytronics' own impressive piece of navigation technology, to scan and create a digital map of its surroundings (i.e. your pool) which it then uses to create the best, most time-effectiveness cleaning path. Ongoing Maintenance As a low-maintenance robotic pool cleaner, keeping it in top form for excellent performance requires very little effort. You just have to pay attention to a few small details. First, Maytronics highly recommends that you clean the filters after each cleaning cycle, and it is very important that you do not let the filter basket dry out before cleaning. To clean out the basket; simply open the filter cover and lift the basket, then the latch at the lower edge of the basket to release the bottom latch, this automatically dumps out the contents of the basket. Then use a garden spray to thoroughly wash it before returning it to the robot. It's that easy! These are the major maintenance tips, but you may also need to periodically clean the propeller. Extra Purchases and ongoing costs No extra purchases are required for the Dolphin Proteus DX5i, it comes as a complete robot and you can unpack and start using it right away. The only extra thing you may want is a pool caddy, although this robot has one, it has to be purchased separately -- and that’s if you want one. This Dolphin robotic pool cleaner weighs about 16 pounds which isn’t too heavy, however, a pool caddy will certainly make mobility much easier. Ongoing costs will include the occasional purchase of replacement parts such as scrubbing brush, rubber tracks, or filters, it’s nothing major and doesn’t cost much. Since the pool cleaner comes with a 2-year warranty from the manufacturer, any problem with the motor or power supply unit within that period will be taken care of by the Maytronics engineer.
