Product Review: Pentair GW8000 Kreepy Krauly Lil Shark

Whether you need to do regular pool cleaning during the summer or you are getting ready to close up your pool for the year, you will need some kind of pool cleaner to assist you. Automatic pool cleaners are the best choice since they do most, if not all of the work for you.

If you have an above-ground pool, you need to get a pool vacuum specified for use with above-ground pools.

One popular above-ground automatic pool vacuum is the Pentair GW8000 Kreepy Krauly Lil Shark.

Pentair has been a global leader in pool equipment for many years. They manufacture high quality products and sell them at reasonable prices.

Now let’s talk about what makes a great above-ground pool vacuum and how the Pentair Kreepy Krauly Lil Shark measures up.

Criteria For A Great Above-Ground Pool Vacuum

Saves Time

The main reason for getting an automatic pool vacuum is to save time; if you had to do the same work manually, it could easily take all day. So a great pool vacuum needs to be able to do its work without your supervision. This allows you to do other things while the vacuum cleans your pool. After a couple of hours, your pool should be clean.

It should clear a wide path as it moves along your pool floor so that it can finish the cleaning quicker.

Good Navigation

Any good pool vacuum should be able to glide around your pool floor without getting stuck at steps, ladders, or corners. It should be able to turn quickly and continue cleaning.

Cleans Thoroughly

A pool vacuum should clean well without missing spots. A great feature that some automatic pool vacuums have is different cleaning patterns you can switch each time so that it covers the entire pool. When it is finished, there should be no debris left behind.

Easy To Use And Durable

An automatic pool vacuum should be easy to set up and use. Many of them come already pre-assembled, which is a big advantage.

A vacuum with many different parts runs the risk of some of those parts breaking, meaning high maintenance costs for you. Most of the best pool cleaners have very few, or even just one, movable part to eliminate high maintenance costs.

Product Overview

The Pentair GW8000 Kreepy Krauly Lil Shark has a dual band of bristles to loosen dirt as it moves along the pool floor. The vacuum action then whisks the dirt away. It cuts a 10-inch path as it glides along, allowing for quicker and more efficient cleaning.

The Pentair Lil Shark can be used on many different sizes and shapes of pools. It has 5 adjustable cleaning paths so that it can clean every inch of your pool.

It measures 12 ¾ inches long, 6 ¼ inches wide, and 13 inches high. It weighs 12 pounds.

The cute design tops off this handy pool cleaner.

The Vortex chamber features just one moving part, ensuring years of dependable service without needing parts replaced.


Pentair GW8000

The Pentair Lil Shark has an affordable price, less expensive than some other automatic pool cleaners. Setup is simple and quick. It has just one moving part and is very durable. It can clean even large pools in a reasonable amount of time.

According to users, the Pentair Lil Shark cleans up both small and large debris.

It is important to keep in mind that the vacuum’s performance also depends on how powerful your existing pump is. If it is too weak, it will not be able to do a great job cleaning. Users that replaced their pump with a better one report that the Lil Shark does an excellent job cleaning.


One complaint users have is that it gets stuck near the ladder of the pool so you have to remove the ladder while it is cleaning. A similar complaint is that it gets stuck in even flat areas of the pool and does not climb well from the deep to shallow end. This requires you to manually move the Lil Shark around to avoid these issues.

Some users also complain that the cord gets tangled so they have to manually untangle it. However when they adjusted the height of the vacuum, this problem went away.

Since it hooks up to your pool’s pump, you have to clean the filter often to prevent it from getting clogged up.


Before purchasing the Pentair Lil Shark, make sure you have a strong pump so that the vacuum can do its job efficiently. You will likely have to keep your eye on it, as many people complain that it gets stuck while cleaning.

If you have the time to supervise the Lil Shark, it will be a good choice for you. If you are looking for an automatic pool vacuum that you can put in the pool and forget about, you may want to look elsewhere.
