This model lacks in features and accessories, but it has plenty of other positive aspects. First, it's very energy efficient so you can manage to make some money savings in the long term. Other than that, it has simple commands so it's easy to use.
Affordable, Hayward’s RC9740 SharkVac gifts you with a way of keeping your in-ground pool spotless, without wasting precious time from your schedule. It is also energy-efficient, reducing the overall electricity consumption by up to 94%, which makes it one of the most efficient units available. It is compatible with several kinds of basins, including salt-water types, therefore providing a wider working range for its user.
Although a bit robust compared to other units, Hayward RC9740 SharkVac, offers an elegant design, compact enough not to occupy more than 24” by 17” by 29”. It sports a relatively light weight, of 21.5 lbs, which ensures moving it around won’t be an issue. A caddy is optional and available to be purchased separately if you wish to store it in a way that won’t clutter your equipment storage. Additionally, due to its reduced weight, there are no chances for the vacuum to deteriorate the lining of the pool, regardless of what material it is.
It sports a durable, high-impact ABS-crafted casing, which not only will protect the unit from external damage but will also ensure the inner components can deal with various water temperatures. Therefore, you can safely keep the water heated, either by eco-friendly sunrays, or through a heater, as the unit will work unaffected by the difference in degrees. To give a helping hand in maneuvering it out of the water, it sports a rear-placed handle, which ensures a wide and tight grip. For increased convenience, it can be folded which will prevent the 50-ft cable from getting tangled.
For underwater mobility, it sports 4 small, side-placed wheels, which, due to their rubberized and pleated design will ensure the robot won’t slip during its job. The wheels provide increased wall-adherence as well as the ability to pass over several obstacles that might get in its way, like forgotten pool toys, or floats. Moreover, the cleaner won’t simply vacuum the floor, but it will also sweep it, removing stuck particles and muck, as the front-placed pleated-bristle brush will actively rotate to enhance the cleaning.
The clearing process implies water filtration, separate from the pool’s own filtration system, which will remove small and microscopic debris particles, trapping them into the debris chamber. The two cartridge filters can tackle tiny algae, leaves particles, silt, sand, and dust, trapping it inside the unit, preventing it from returning into the water. Even more, the filter chamber is placed at the top of the unit, which gives its user hassle-free access to it for debris removal or cleaning.
It utilizes a smart navigation technology that actively scans and calculates the best route for fast cleaning. Thus, it will memorize the shape of your pool, and will actively seek better ways to achieve a total and spotless, clear, result. It provides two cleaning modes, a fast, QuickClean one, which lasts only 1 hour, and a standard cycle which lasts 2 hours. Therefore, according to the pool needs as well as your preferences you can opt between the two.
Additionally, it offers a programmable function, which enables you to select the desired time when the clearing should commence. You can set it up to function during night hours, so you’ll wake up to a sparkling pool, or during your work-hours to enjoy an afternoon spent leisurely at your pool, relaxing on the chaise lounges. However, if you decide to utilize it at night, make sure that no cover will impede its operation, nor can the cord get caught in other outdoor elements.
For increased safety, it includes an out-of-water sensor, which detects the moment the robot is removed from the water body. If this happens in the middle of its program, it will automatically terminate it, shutting the motor to prevent overheating or damage. It will also sense when it is diverted from its path, as the robot will register your attempt to pull it out of water. If the action is not finished, and the robot remains submerged, it will relocate itself, resuming its previous path. By doing so, it will not only continue the vacuuming, but it will ensure proper distribution of chemicals, resulting in better water balance as well as enhanced circulation. However, due to its ability to reach several areas, you should remove any floating devices, like ozonators, ionizers, or chlorine-tablet dispensers, to ensure hassle-free operation. Even more, if you own water-floating pool alarms, you should also remove them, as the underwater waves created by the robot, will trigger them.
Thanks to its compact and robust design, you shouldn’t have to worry about its regular maintenance, as the unit was built with a long-lasting activity in mind. It has few moving parts, therefore it is less prone to irremediable damage, whereas the parts that can get worn out – the brush and wheels, respectively, can be easily replaced. However, what you should pay attention to, is the filters, as they will require clearing after every utilization. A thorough rinse done with a high-pressure water jet from your backyard hose should suffice. And if the dirt stubbornly sticks to it, you can utilize a soft brush to detach the particles. When exposed to unbalanced water, high alkalinity will create calcium deposits on the robot’s inner pieces, resulting in faulty utilization. Even more, regardless of the fact that the manufacturer warrants the unit for the entirety of the first year, if it is exposed to high amounts of chlorine or a high level of pH, the casing will start to deteriorate faster. Even more, although the unit is powerful and can remove several types of media, it can’t deal with stubborn algae types.
Fully capable of transforming the pool-cleaning chore into a hassle-free task, Hayward 9740RC SharkVac is not only affordable but also energy efficient. It can tackle both floors and walls, to an extended degree, depending on how the pool has been crafted, but, overall it will thoroughly do its job. The only aspect that might require your attention is its power cord, as it tends to get tangled easily. Otherwise, it is a cleaner that sticks to its task, keeping the basin spotless.
