Hayward RC9740 SharkVac Automatic Robotic Pool Cleaner Review

The Hayward RC9740 SharkVac Automatic Robotic Pool Cleaner is a automatic robotic cleaner with a robust design capable of cleaning pools in a gentle and smooth way compatible with all kinds of pool sizes and surfaces. It scrubs the pool floors, cove and walls with an inbuilt scrubbing brush which will clean off even the most difficult of dirt.

Robotic cleaners are the most advanced type of cleaners in the world of pool cleaners. Steps ahead of their suction-based and pressure-side counterparts, they feature some pretty incredible technology, top quality design, speed, and efficiency. They may come with high price tags, but with your robotic cleaners, you don't need booster or filter pumps, suction ports, extra hoses, and skimmers to get the best out of them.

They feature their built-in filters, so they don't need the pool's circulation system to function. They do not need supervision of any sort, you just plug the cleaner into an outlet and let it do its work. The Shark Vac RC9740 is part of the Hayward SharkVac series which come with their list of impressive features (though it's really not too different from the Tiger Shark). So let's explore the SharkVac RC9740, its buyer reviews and just how good the product is.

The SharkVac can work in any kind of pool from vinyl, concrete, gunite and fiberglass. The best part is that this cleaner doesn't require a booster pump to function.

One of the best features of this cleaner is that it comes with a programmable cleaning cycle that allows you to set the cleaner to clean your pool a night before or you can set it to clean when you leave the house for work in the morning. The only problem with this method is that it's not advisable to leave the cord in the water for too long as the chlorine could lead to wear and tire.

It has the customer's convenience at heart and it was designed with enhanced technological features. It is economical and easy to operate using as much energy as a light bulb.

This robotic pool cleaner is suitable for in-ground pools of up to 20 X 40 " wide and it works well with all pool surfaces. It is well designed with designs that are unmatched by other robotic cleaners that we have reviewed in the past. It provides easy top access to filter cartridge and two fine porosity filter elements.

Pool Type

The SharkVac Robotic cleaner is suitable for any kind of pool type or size. What you need to do is to drop this robot into the pool so it can begin to clean automatically without your involvement. This cleaner automatically computes the size and decides the best cleaning patter based on your pool size and shape. You can also activate a feature called the Fast-Clean.

The Fast-Clean feature allows the SharkVac increase its speed so it can finish the cleaning of your pool within an hour. Better still, you can allow this robotic cleaner to work its magic till it's done cleaning your pool within the duration of its cleaning cycle. If the SharkVac finishes cleaning before the 2 hours cycle is up, you can simply remove the cleaner from the pool and turn it off manually.

This pool cleaner will clean the waterline of the pool, the steps as well as the walls effectively.

We have explored the features of the product, the next question is, why should you buy the Hayward RC9740 SharkVac? There have been very positive reviews from buyers of this product and the occasional negative review as well, let's look at some of them

Battery Usage

The SharkVac is very efficient in the amount of energy that it consumes. It consumes same energy as a standard light bulb and we believe it will save you a lot on energy payments.

Setup and Use

This cleaner is easy to setup and use. It comes with detailed instructions from the box that will inform you on how to assemble the cleaner in minutes. Once this is done, you will need to plug it into a GCFI power outlet before dropping it into the water to clean.

Cord and Pool Size

The cord of the SharkVac RC9740 is quite long (60 ft.) and it has a Kevlar reinforcement as well to prevent wear and tear. There is an option to have a Caddy with your cleaner which we recommend considering this cleaner weighs 21.5 pounds


The SharkVac is a reasonably affordable robotic cleaner, and it does a decent of cleaning your pool well. It completes its cleaning cycle in a short time and during that time it manages to cover the entire pool.

It has some few drawbacks such as flipping over or sideways as it cleans, this may be a result of the different sizes and shapes of pools that it cleans (for a more complete cleaner check out the Dolphin Triton).

It is also quite heavy and not a joy to lift or carry around. Barring all this, I would say it's a good buy and worth the price you pay for it, but you can do better with another Hayward product, the Tiger Shark, if you're willing to spend a little more.
