Pool Vacuum Cleaner

Having a pool is fun, moreover if you live where the summer can be pretty hot. The pool is an accessible and convenient entertainment for the whole family to enjoy together, especially if you have young children. The kids love playing at the pool, but we also have to pay attention to the water quality. In an open space, a large amount of water attracts much debris, especially light enough for the wind to carry. A reliable filtration system can help a lot, but you may need to add a pool vacuum.

As the name suggests, a pool vacuum is a tool to help clean the pool. A regular vacuum will take debris from your flooring, and a pool vacuum will do the same. The only difference is that they are sucking water instead of air. A pool vacuum is very common and is an excellent investment for pool owners. Their price varies depending on how the vacuum works. The most affordable vacuum requires manual navigating from the user using a long telescoping pole to swipe the bottom of the pool.

If you want a more convenient system, automatic suction-side variants such as Zodiac G3 Vs MX6 are ideal. This type of vacuum needs the pool’s filtration system to suck water and clean it. We may need to calibrate the pump’s suction to match the vacuum’s requirement; some vacuums need high water flow to move around the pool. If you want a more straightforward system that doesn’t need the pump, we can choose a robotic pool vacuum with an independent motor to create suction power.

About Dolphin Sigma and Polaris 9650iQ

A robotic pool vacuum is the easiest to use because we don’t have to dial the pump, and many come with extensive features to help you clean the pool. The only drawback is they can be quite more expensive than any other type of pool vacuum. But, if you want the most straightforward filtration, a robot vacuum will be beneficial. They are reliable and suitable for in and above-ground pools, depending on their size and vacuum capacity.

Many companies offer good robot vacuums so you can choose wisely. When buying a robot vacuum, the main factors are the pool size and types. Some robot vacuums are only reliable for above-ground pools, while some are versatile for in and above-ground pools. The Dolphin Sigma and Polaris 9650iQ are perfect options to consider if you have a relatively large pool. These vacuums are convenient, powerful, and intuitive. They also come with modern features to improve user experiences.

While Dolphin Sigma and Polaris 9650iQ come from different companies, the two share many similarities. You may wonder which vacuum is worth buying because Dolphin vacuums are usually more expensive than many competitors. The two are very similar in the setup, operating, and maintenance process. We like the Polaris better because this vacuum is faster to clean up, thanks to the filtering system that is also bigger than Sigma. However, Sigma also has an advantage thanks to its higher feature.

The filter and technology are the main differences between Dolphin Sigma and Polaris 9650iQ. We think the Polaris is more practical and better for users dealing with large debris. But, Sigma is currently one of the most technologically-advanced pool vacuums available that can design a more precise cleaning system. Unfortunately, the price is often much higher than many of its competitors.

Dolphin Sigma and Polaris 9650iQ Designs

Both Dolphin Sigma and Polaris 9650iQ are in-ground pool models that will work for above-ground pools. They are ideal for small and large pools up to 50 feet for the Sigma and 60 feet for the 9650iQ. The designs of these vacuums are pretty different, with Sigma featuring a huge handle at the top and 9650iQ two pairs of large rubber wheels. The Polaris 9650iQ reminds us of a canister vacuum due to the top-loading mechanism. The Sigma is also a top-loading model but slightly different.

The vacuum is primarily plastic which makes sense because we will be submerging them in the water. The brushes are firm rubber to help agitate the embedded dirt. Another noticeable difference between these vacuums is the cleaning channel in which the Sigma has two shorter openings while 9650iQ has a longer single-suction path. The Sigma comes with a 60 feet cord, and the 9650iQ comes with a 70 feet cord. The Polaris 9650iQ also has a caddy that acts as its control panel and power supply.

Dolphin Sigma and Polaris 9650iQ Setup

One of the best things about a robotic pool vacuum is the ease of setup. But, since the Polaris 9650iQ comes with a caddy that acts as its power supply and control panel, we have to assemble this equipment first. Follow the manual as the unit comes in parts. After everything is built, we can start the cleaning process. The Sigma comes with a small power supply that you have to connect to wall power, the same with the caddy for 9650iQ.

Connect the floating cable from the vacuum to the power supply and slowly submerge the vacuum cleaner in the pool. Put a cable length depending on the pool’s size so the vacuum pod can move easily underwater. Once the pod is at the bottom of the pool, we can press the power/cleaning mode. The vacuum will move across the pool’s floor, collecting dust and larger debris. Make sure that the pool is clean from any floating items to minimize the chance of tangling.

Dolphin Sigma and Polaris 9650iQ Technology

The Dolphin Sigma and Polaris 9650iQ work using the exact mechanism as many robotic pool vacuums. The electricity powers a small motor inside to create a vacuum suction. The vacuum suction is sucking dirty water and debris into the filtering chamber. The debris and small particles stay in the filter while the clean water gets back to the pool. These vacuums also have a dedicated motor to spin the wheel and help the pod powerfully climb stairs or walls. The wheels are made of rubber to stick on a wet surface.

The anti-tangle cord on both vacuums is handy to keep the cable from getting tangled. Many vacuums twist on their cord as the cleaning pod moves across the flooring. The twisted cable can prevent the vacuum from reaching certain parts of the pool to do its job.

Dolphin Sigma and Polaris 9650iQ Features

Another main difference between Dolphin Sigma and Polaris 9650iQ is their features. The 9650iQ may be cheaper, but this vacuum comes with plenty of onboard features which can be more convenient for some people. You can choose three cleaning modes; floor, floor and wall, and waterline from the caddy. The cleaning cycle time is adjustable from the control panel or phone’s app. The control panel displays the remaining cleaning time and notification when the filter canister is full.

This pool vacuum also has a lift system to push the cleaning pod from the floor and make it easy to pull it. On the other hand, Sigma has a simple, minimalist control panel with just a cleaning button. You will need to download and use MyDolphin Plus IoT mobile app to access the extended features, such as manually navigating the cleaning path and designing a cleaning schedule. In addition, Sigma also has Smart Navigation with Gyroscope technology for more precise cleaning performance.

Dolphin Sigma and Polaris 9650iQ Performance

Lastly is for the Dolphin Sigma and Polaris 9650iQ overall performance. Both pool vacuums are excellent and reliable. They move pretty fast across the floor’s flooring and have no issue climbing the walls. They can handle walls and waterlines without much fuss. But, the Polaris 9650iQ has a specific cleaning mode that tells whether it cleans only the waterline or other areas. The control panel of this vacuum is one of the best because it is rich in features and very convenient to use.

The maintenance is also similar, but we like Polaris 9650iQ better because the filter is easier to take out and clean. Both vacuums have a top-load mechanism, but Sigma uses two filter arrangements, while 9650iQ uses one large basket containing more debris from leaves, small twigs, and seeds. If your pool has plenty of large debris, we have to clean the Sigma more often.

Dolphin Sigma Vs Polaris 9650iQ

Both Dolphin Sigma and Polaris 9650iQ are reliable in performance. They can take small and large debris, don’t tangle, don’t get stuck, and can climb walls while cleaning the waterline at the top. But, the Polaris 9650iQ has a more intuitive user interface and features on the control panel, so you don’t need the app to enjoy all of its features. This vacuum also has a large canister filter that fits best users who often struggle with large debris like leaves and small fruits from nearby trees/plants.

The decision is yours because both are great options. We recommend Sigma if your pool’s issue is fine debris and Polaris 9650iQ if the pool has plenty of leaves and large debris. We also like Polaris because it is cheaper, has plenty of features, and has a large canister filter.
