Water filtration vacuums can purify the air inside your home, creating a perfect environment for people with such health conditions.

Moreover, if you’re a perfectionist who loves the floors or carpets to be sparkling and screaming “I’m too clean,” then a water vacuum cleaner can also be your first step towards that goal.

In this guide, I’ll help you zero in on all of the finest water filter vacuum options, but first, why should you trust us in the first place?

Why do you trust us?

Part of the Cleaners advisor team, I’ve spent nearly 40 hours of research on Water Filtration Vacuums, dove through nearly 20 vacuums that claimed to work as a water vacuum cleaner.

Users have posted hundreds of reviews on those vacuums, some were positive, others were completely negative, but I read them all, and studied the patterns of success and failure.

For this Guide of Water Filtration Vacuums, you’ll find the pinnacle of my tens of hours-long research, which should pave the way for your decision, should I buy a water filtration vacuum cleaner, or not.

What is a Water Filtration Vacuum?

You’ve probably heard of upright, and canister vacuum cleaners before, they are famous enough and there is one of those two vacuums somewhere inside the house of nearly everyone you know.

However, with constant development in vacuum technologies, a new and effective type of vacuums has started to gain ground in the market, for its merits, it’s the Water Filtration Vacuums.

They suck up dry and wet dirt and clean your floors and carpets deeply & thoroughly. However, they collect such dirt inside a water filter, instead of a dustbin.

If your main vacuuming problem is with shag carpets or vinyl floors, I have prepared a list of the best vacuum for shag carpets, and a similar one for the Best Vacuum for Vinyl Floors.

This is the crucial difference between original vacuums (upright/canister) and new water filtration vacuums, alongside other differences we’ll get to later in this guide.

How do Water Filtration Vacuums work?

In water filtration vacuums, you don’t have a dustbin, nor do you have a dirtbag, you have a transparent compartment filled with water.

When the vacuum sucks the dirt (dry or wet), it’s moved straight towards the water-filled compartment.

This serves as a better way to trap the dry dirt, and prevent it from escaping back out of the vacuum.

Furthermore, this also helps with sucking wet floors, as in regular vacuums, sucking water will create chaos inside the dustbin.

On a side note, you may find the looks inside the water-filled compartment a bit gross, but it’s a dirt bin, after all, you won’t find jewelry there “Kidding”.

What makes Water Filtration Vacuums a better choice?

I’ve walked you through some of the main pros you can find inside a water filter vacuum, but here’s a full list of pros of the water filtration vacuum cleaners:

  • Effective on both Dry & Wet messes
  • Suitable for cleaning Pet Hair
  • Have the capacity to hold up to more dirt
  • Perfect for people suffering from allergies and asthma
  • Better environment overall inside the house
  • No incidents of clogged filters at all

However, such pros come at a price, so what are the cons of those Water Filtration Vacuums?

  • Water Filtration Vacuums require a bigger water compartment, meaning it’s heavier
  • Cordless options consume so much power
  • Usually more expensive that regular vacuums

What to look for in a Water Filtration Vacuum?

How can you judge a Water Filtration Vacuum, and how can you judge which one is the best water vacuum cleaner?

Follow are the main categories in which you can differentiate water filtration vacuums:

  • Type: Is it built as a canister or an upright vacuum?
  • Floors: What floors does it cover?
  • Carpets: Is it suitable for carpets? And what types of carpets does it suit?
  • Mess type: Does it work on Dry Mess only? Or both Dry & Wet?
  • Weight: How heavy is it? Does that disrupt the vacuum’s movement?
  • Budget: Vacuums vary in price, does your budget have enough for any vacuum or only a handful?
