Water Filter Vacuums Vs Regular Vacuums

A water filtration vacuum works actually like a regular vacuum cleaner, except it uses water to filter the dust and dirt.

Unlike a regular vacuum, it filters and traps dust particles inside a water chamber so that it doesn’t expel back into the air after vacuuming. As a result, it provides fresh, clean air that’s been filtered through water.

On the other hand, standard vacuums filter the air through filter bags. These standard filters trap all the dirt and dust and then exhaust the polluted air back into your home.

There are also no bags or dusty containers to handle when using a water vacuum. So they’re easy to maintain and are less likely to get clogged.

So, water filter vacuum cleaners are perfect for households with allergy or asthma sufferers. They’re also great for pet owners.

Plus, unlike traditional vacuums, these water filtration cleaners can vacuum water. Whereas vacuuming water with a standard vacuum will almost certainly damage the unit.

Are Water Filtration Vacuums Worth It?

Yes, we think so. Water filtration vacuum cleaners offer many benefits.

accordion_icon

Better Air Quality

A water filtration vacuum filters 99.95% of dust and air pollutants.

They use water as a filter and dissolve tiny dust particles and microbes that are suctioned as you vacuum in water. This means that less dirt can escape the filter. This not only purifies the air but also keeps the exhaust cleaner clean.

As a result, you have significantly better air quality. This is particularly suitable for allergy or asthma sufferers because a cleaner air environment ensures healthy indoor air quality (1).

Plus, they purify the air without the need of relying on a scent disc or odor filter for clean air.

And with some models, you can also add fragrance to the water. This way, your vacuum also features as an air freshener while you clean. So you don’t have to buy a humidifier, an aromatizer, or an air purifier for your home.

No Loss of Suction

Another benefit is that you won’t lose any suction or airflow quality while you’re vacuuming with a water filtration vacuum.

Standard vacuum cleaners lose suction power when they are clogged or full. And when this happens, you have to empty it before you can continue cleaning. However, with water filtration machines, you won’t have to worry about any clogging. The water traps the dirt, so nothing can get clogged.

You also won’t have to worry about cleaning or replacing your filter to maintain suction. Plus, the water is able to hold more dirt. So compared to other vacuum cleaners, you can vacuum up more dirt and debris before needing to replace the water.

Clean Wet and Dry Messes

While traditional vacuums can’t handle wet messes, water filter vacuum cleaners can.

And unlike wet-dry vacuums, you don’t need to worry about having two separate canisters to hold wet and dry messes. With a water filtration method, you can do both without having to change any settings or use separate canisters.

accordion_icon

Versatile

Water filtration vacuum cleaners are versatile units that you can use for almost any cleaning situation. And they also come with various attachments and products to use for different purposes.

For example, some come with a basic cleaning solution that effectively cleans debris and dirt from your carpets. It also freshens your air without leaving an overwhelming fragrance.

Some models include a carpet shampoo attachment as well. This means you can use carpet foamer with your vacuum too without needing a separate tool.

Plus, there are many other creative ways you can use your water filtration system. For example, you can use it to water plants or clean your windows. And, you can even use it to wash delicate items such as curtains or shag-pile rugs.

Lastly, they’re also perfect for trapping pet hair. And you won’t have to worry about any hair wrapping or getting clogged in your vacuum.

Easy to Use & to Maintain

Cleaning with a water filtration vacuum is a breeze. All you have to do is fill it with water from your tap and you’re ready to clean.

Adding fragrances to your water is also simple. You add a few drops to your water tank before cleaning, or you can add them in the middle of your clean. And you don’t have to turn it off or open the vacuum tank to do it.

Other than that, you use your water filtration vacuum cleaner just like you use a normal vacuum.

Finally, these machines are super easy to maintain. As we mentioned above, you don’t need to change or replace any filters. And you’ll save a lot of cleaning time not having to worry about clogging.

Plus, the canisters are easy to empty. There’s no messy bags or dusty containers to handle.

How Do a Water Filtration Vacuum Cleaner Work?

Water filtration vacuums work using a water filtration technology system.

Dirt and debris are sucked up with normal air suction and passed then through the water. Contaminants such as pet hair, debris, and dust are trapped and dissolved in the water.

A fan motor inside of the vacuum rotates the water rapidly to efficiently filter out pollutants. On some models, the air is then passed through a HEPA filter that traps any remaining particles or debris in the water.

Finally, after being filtered and washed, the clean air is then expelled back into the environment.

How To Choose the Best Water Filtration Vacuum Cleaners

There are a few things to consider when choosing the best water filtration vacuum cleaners for your floors.

accordion_icon

Types

First, consider the type of vacuum. There are two types of water filtration models: upright or canister.

Upright Vacuum Cleaner

An upright water filtration vacuum is an all-in-one vacuum that has a cleaning head, handle, and canister or bag.

This type of vacuum is pushed in front of you when you’re cleaning, using a handle that’s attached to the body. This can often feel heavier to push than other models. However, the extra weight tends to provide more suction power.

Upright models have a rotating brush-roller or beater bar for powerful suction. The vibrating bristles effectively lift and remove dirt as you clean. For example, see this Quantum upright model.

Canister Vacuum Cleaner

A canister vacuum has a wheeled body attached to a wand and floor-head with a flexible hose.

These models are often preferred for their lighter weight. Instead of pushing the whole weight of the vacuum, you only need to move the wand and floorhead while vacuuming.

Plus, the wheels make it easy to drag the canister body behind you as you go. But, the wheels can be hard to maneuver on high-pile carpets and can get easily caught. For example, this Kalorik water filtration vacuum is a canister model.

Consider your carpet needs when choosing a vacuum that is most suitable for your floors.

accordion_icon

Filters

Of course, all water filtration vacuums have a water filter built into them. However, some have additional HEPA filters.

HEPA filters have been tested to trap a lot more dirt and dust particles than many other filters. They remove 99.9% of all airborne particles that are larger than 0.3 microns (2).

Because water filtration vacuums use water, you’ll need to clean your HEPA filter more often. They can get dirty quickly when coming into contact with water, especially if you don’t clean it enough.

For example, this Polti vacuum has a washable HEPA filter.

accordion_icon

Weight

Depending on where you’ll be using your vacuum, you should also consider its weight.

If you want to clean multiple surfaces and levels, you should consider a lightweight model that’s easy to carry. If you’re lugging your vacuum up and down a staircase, a heavy vacuum can cause a lot of strain on your back.

But, if most of your cleaning will be on one level, then the weight will be less of an issue.

Another thing to consider is the suction power of your vacuum. Lightweight water filtration vacuums tend to have less power than heavier water vacuums. So if you need strong suction power to clean embedded dirt or debris, consider a heavier model with more power.

For example, this Kalorik model weighs 14 pounds. Whereas this Quantum X upright is a lot heavier at 30 pounds.

accordion_icon

Noise

It’s also important to consider the noise level of your carpet cleaner depending on your environment. In fact, water vacuums can be loud machines.

For example, low noise is considered to be between 57-62 decibels. Whereas an average water filtration vacuum cleaner makes 84-89 decibels of noise (3).

A noisy machine can be a nuisance, especially if you live close to neighbors. So look for vacuum cleaners with a noise level of around 55dB which is the same as a normal conversation. Or, consider a vacuum that has power settings that can provide quieter operation for when you need it.

accordion_icon

Warranty

A water filtration vacuum can be a significant investment. So it’s important to consider the warranty terms.

A good warranty can help you if your vacuum has a defect and you need to replace it. Different brands have different warranties, so consider a warranty that will provide a good cover for your product.

For instance, Sirena offers a 10-year motor warranty, a 3-year parts warranty, as well as a 1-year labor warranty.

So you should check the manufacturer’s website to find the warranty details for your vacuum before you buy. Or, contact the seller.

accordion_icon

Budget

There are different options to consider, depending on your budget.

There is a large price range for water filtration vacuums. And this can vary depending on features and quality. However, vacuums with water filter vacuums tend to be more expensive than standard vacuums.

For example, the Quantum water vacuum is $430. Whereas this Sirena model is around $900.

accordion_icon

Brands

Finally, consider the brand of your vacuum. There are a lot of different brands to choose from. However, we recommend sticking to cordless stick vacuum brands.

These are some of the top-rated cordless stick brands available:

  • Ocean Blue
  • Kalorik
  • Ovente
  • Karcher
