3 Best Robotic Fiberglass Pool Cleaners

1. Dolphin Premier Robotic Pool Cleaner Review – Best Overall

This. Does. Everything. If you’re trying to find a short review, that’s it.

If you’re trying to find a far better explanation…this thing arrived, we got it out of the box and soon rolled it into the pool. It had been super simple to line up, and it cleaned our pool within a few hours.

We know tons of individuals who own this pool cleaner, and we’ve never anyone complain about it getting stuck, which in itself is pretty amazing. There’s nothing worse than fixing your pool cleaner, getting your hopes up, then coming home to a pool that’s still dirty and a cleaner that’s stuck. If you would like to avoid that scenario, you ought to accompany this one.

It’s also up to 87% more energy efficient than older models on the market. That’s quite revolutionary, and something that your wallet will enjoy.

Our only beef with this model was its price. This type of cleaning doesn’t come cheap. However, with the 3-year warranty, and a pool cleaner that never gets stuck, this investment is certainly worth considering.


  • Fast cleaning
  • Very reliable (we’ve never seen it get stuck)
  • Cleans everything
  • Easy to line up


  • Not a budget buy

2. Polaris F9550 Pool Vacuum (Robotic) Review

The F9550 may be a great all-around cleaner. It’ll devour any size debris and roll in the hay quietly. If you would like to be ready to read the newspaper and sip coffee while your pool is cleaned then take a dip in clean water, you won’t be disappointed.

It’s also cheaper than the Dolphin Premier Robotic, therefore the reasonable question is why we didn’t rank it before that one based purely on value.

It’s much slower for starters. And it doesn’t always clean the whole pool, and if you are trying to urge it to via the remote it’d take what seems like an eternity for it to reply. Plus, it won’t clean the stairs. So, while we feel the essential clean may be a better value than that for the Dolphin, for these reasons we might advise that you simply invest extra money during a superior piece of kit.


  • Fine cleaner
  • Great traction
  • Works great without supervision


  • Slow
  • Remote a pain within the neck
  • Doesn’t clean stairs

3. Polaris Vac-Sweep 360 Pool Cleaner Review – Best Value

Unlike the opposite two, the Polaris Vac-Sweep 360 may be a pressure-side pool cleaner, which suggests that it’s powered using the water in your pool on a pressure line.

We chose it because it’s an excellent reputation among Consumers, and our tests show that reputation is pretty much deserved. It picked up large debris like leaves and twigs sort of a champ, and it did an adequate job on small particulate like sand. At the worth, it’s a little thing.

What it’s against it had been difficulty gaining traction on a fiberglass finish. It can still get the work done. Just don’t watch it, because you’ll come away frustrated. It is also clearly not intended for an above-ground fiberglass pool. If you’ve got one among those, you’ll get to find a special option. But, still, the cleaning it delivers at the sticker price makes it the simplest for-dollar value of the models we tested.


  • Great at cleaning large debris
  • Adequate at cleaning particulate
  • Affordable compared to other models


  • Doesn’t work on above-ground pools
  • Has difficulty gaining traction on fiberglass

Pool Cleaners for Fiberglass PoolsBuyer’s Guide

Our tests left us impressed that the foremost expensive model is that the best one available at cleaning fiberglass pools.

That doesn’t mean that it’s the simplest one for you. Ultimately, your purchase shouldn’t just be a matter of throwing dollars at a drag but finding the proper choice. this is often especially the case for fiberglass pools, which tend to be easier to wash and have a tendency to be less of a grime magnet than concrete pools.

It’s just that during this case if you’ve got a gob of cash lying around, you’d probably be happy throwing it at the pool debris issue. If not, or if you came to possess a gob of cash by being very careful in how you used it, there are some issues you’ll want to require under Consideration in knowing which one is true for you.

Above or in-ground, that’s the question

The first thing to factor into a fiberglass pool cleaner is going to be whether you’ve got an above-ground pool or an in-ground one. That might immediately push you far away from our bargain model, the Polaris Vac-Sweep 360, which isn’t suitable for above-ground pools.

But because those pools tend to be much smaller than in-ground pools, you would possibly want to avoid the opposite two we tested, too. Buying one among them would be tons like buying a car specifically to drive around the block to shop for a gallon of milk. There are great alternatives on the market that will clean away smaller above-ground pools for tons less money.

Big debris versus small

If your pool tends to urge cluttered with branches and leaves, you’ll want to seek out a pool cleaner better fitted to large debris than one which will pack up small. Or one which will exchange bags for filters. That’s one of the items we actually liked about the Dolphin Premier Robotic. With just a fast swap out of a filter for a bag, you’ll get everything cleaned up in your pool with little hassle. The difficulty of massive debris in your pool can vary counting on which part of the country you reside in. If you reside within the desert Southwest, you’ll want something which will handle sand. If you reside in Michigan on the opposite hand, you’ll probably get tons more pine needles and maple leaves.

Traction matters

Fiberglass pools are less grime-prone than concrete pools because the floors are much less porous. Meaning particulates and dirt accumulate instead of sticks, but it also means more difficulty for pool cleaners to realize traction on them. We actually liked the Polaris F9550’s floor-gripping wheels for this reason. It’s also something to stay in mind if you check out other models. Something could be lights-out when it involves learning leaves and grit, but which will make little or no difference if a scarcity of traction has it spinning its wheels.

Robotic vs. Pressure-side vs. Suction-Side

There are three basic sorts of pool cleaners: robotic, pressure-side, and suction-side. Each has distinct advantages and drawbacks that you’ll want to think about choosing what cleaner is right for your fiberglass pool.

Robotic cleaners are the foremost expensive, the foremost autonomous, and usually deliver a superior cleaning performance. A pressure-side cleaner runs on water pressure and does an excellent job of learning larger debris. If your pool isn’t equipped to handle a pressure pump, you’ll need to purchase a separate booster pump. Suction-side cleaners are the foremost affordable, but because they run on the facility of your pool’s main pump it strains on them.


More expensive doesn’t always translate into a far better investment. During this case, it did. We checked out three different pool cleaners for his or her ability to handle fiberglass pools, and therefore the one that cost the foremost money — far and away from the foremost money — just simply outperformed the competition. It cleaned everything and cleaned it quickly.

If you follow up and buy the Dolphin Premier Robotic, we’d recommend investing in both filter cartridges and a bag.

If it’s an excessive amount of money, the Polaris F9550 may be a good second choice. It does an excellent job cleaning and may go anywhere, but you’ll want to wash the steps yourself or a minimum of pay an adolescent to try to do it for you.

An excellent value alternative is that the Polaris Vac-Sweep 360, the highly vaunted pressure side cleaner, even as long as you’ve got an in-ground pool. If none of these options appeals to you, we hope you discover our buyer’s guide helpful in making an informed purchase.
