Technical specifications

This automatic pool cleaner is suitable for in-ground pools of various sizes and made of all kinds of materials and it manages to clean every inch on the pool’s floor, walls, and steps. It can clean an entire pool in about 1 hour and it can cover up to 5900 square feet while limiting the hassle of bulky cleaning pumps. It comes with PVA brushes that ensure a perfect dirt removal and great absorbency of debris as small as 2 microns. This device can filter up to 4,255 gallons of water per hour and the built-in filter bag picks up and retains any impurity.

Features

One of the most important features of this automatic pool cleaner is that it can clean any corner of the pool, including the steps and it hardly gets stuck in corners or flips over. A stainless steel material supports the wheel tubes for better stability and the motor is pressure-tested underwater at a 17′ depth. This pool cleaner is equipped with 2 sensors, a beach entry detector to keep it from exiting the water, and an obstacle detector to keep it away from obstructions. The intelligent navigation allows it to create a route that it follows in order to ensure a thorough cleaning on the entire pool area. Although it is a very expensive model, this robotic pool cleaner doesn’t come with a programmable timer or an automatic shut-off feature, which takes away from its convenience and comfort in use.

Design and accessories

What first attracts you about this pool robotic is the cute design with a plastic housing in pink and blue that almost looks like a little girls’ toy. It’s very small and compact measuring only 18 x 16 x 13 inches and the only thing that tells you it’s not a toy is the 23 pounds weight. Still, you can easily get it in and out of the water thanks to the long and comfortable handle on top of the device. A great design hack is that this pool cleaner comes with a storage caddy that fits the actual device and the power cable so that you can easily store it and move it when you need to use it. It doesn’t have wheels, but tracks that allow it to move faster and make it more durable, although going over bumps will be harder. The rotating brush aid its movement as it pushes the robot forward into the water. It comes with a swivel cord which keeps it from getting tangled so you don’t have to be there to put it back on track.

Noise and energy efficiency

With only 12 volts of power, this device is extremely silent and energy-efficient and the intelligent features it comes with add to its energy saving. The pre-programmed computer guidance system controls the route of the robotic pool cleaner in order to minimize the number of useless moves, which results in a lower operating time and a higher efficiency. Furthermore, the rubber tracks and the soft brushes add it adherence so that it won’t slip on the pool’s surface and it won’t move excessively without a target.

Ease of use and durability

This model comes fully assembled and ready to start cleaning your pool. The 4-year warranty offered by the manufacturer ensure the best operating for up to 500 cleaning cycles and adds a great value to the product as it limits the maintenance costs. Considering that you will also receive the long cord and the storage caddy for easy transportation, you will enjoy the comfort of this pool cleaner without spending extra money on these accessories. The PVA brushes not only offer an improved cleaning but also make it very durable and reliable.

Important Maintenance Tips

For you to make sure that you’re safely operating the unit and that you won’t damage it or put yourself in danger, you must be aware of certain important maintenance tips. The most important thing that you should be aware of is to always shut off and unplug the robot before you remove it from the water to avoid getting shocked. Also, when a clean cycle is finished, let the robot rest in the pool for 15-20 minutes before removing it. For the unit to be by your side for as long as possible, you must make sure to always clean the filter bag after every use. Once in a while, straighten out the floating cable to ensure that it won’t get damaged. Last but not least, don’t forget to clean the propellers of the robot once every month to ensure a proper performance.

Final Thoughts

Despite the childish design of this product, this robot pool cleaner is among the best performing units on the market. This took us by surprise as well, but after reviewing it, we can safely say that it’s an investment worth making. The 4255 GPH filtration rate and the capability of picking up particles as small as 2 microns from the water and surfaces of the pool are two elements that make it a force to the reckoned with. The tracks that it features don’t only make it more durable, but they ensure a fast movement, meaning that the unit will be done with cleaning the pool in less time that you’d expect. But what makes this model shine is the intelligent navigation system that it comes with and that ensures it will find the most optimal path to clean the pool, thus allowing a low-cost operation that you will definitely love. All in all, you shouldn’t let the playful design of the unit trick you because it’s one of the best options on the market.
