Karcher WV5 Premium

Best Performing Window Vacuum

Karcher WV2 Premium

Karcher WV5 Premium

With excellent battery life, a super-lightweight body and excellent streak-free cleaning, our top recommendation is this excellent Karcher window vac.

Germany-based Karcher is a global leader when it comes to cleaning equipment for your home.

The company invented the battery-powered window vacuum, and they flex their expertise with this product.

The WV5 Premium is, quite frankly, the best performing window vacuum we have come across - period.

Weighing in at only about 700 grams, this is a highly nimble cleaning device.

This cordless beauty has 35 minutes of battery life, which is sufficient for all of your windows at home.

The battery has a charge time of over three hours though.

Our team of testers were astounded at the streak-free finish and drip-free performance of this window vacuum.

The all-around performance on mirrors, porcelain tiles and even hard floors was one of the many reasons why we rate this window vacuum so highly!

The cleaning kit that we received with this vacuum has a window detergent and a microfibre pad to prevent scratches on your mirror.

To aid edge cleaning, this vacuum has a suction blade included to clean up some tricky spots.

We also found the suction device helpful in sucking up tiny spills at home, which is a great additional benefit.

In our tests, we could see that the WV5 Premium does an excellent job of getting rid of watermarks and leaving no trail behind.

The capacity of the vacuum to hold dirty water is only about 100 millilitres, which is a bit disappointing.

We did love that the wastewater compartment was easy to empty though!

While the price is a little steep for a window vacuum, the performance of the Karcher WV5 speaks volumes!

  • Excellent battery running time at 35 minutes
  • The great suction tool makes edge cleaning easy
  • Streak-free cleaning performance
  • Lightweight at about 0.6 kilos
  • Easy to empty wastewater
  • The wastewater canister capacity is limited
  • The battery takes three hours to recharge
  • Hefty price tag for a window cleaner


Best Premium Window Vacuum



Easy wastewater emptying, a USB charging unit and decent battery life, mean that to overlook this Kogan window vacuum would be a mistake.

When Kogan entered the UK market at the beginning of this decade, it became the first Australian-owned electronics brand with an international presence.

This affordable window vacuum cleaner from Kogan demonstrates just how underrated their products are, even within Australia!

With enough battery life to clean 150 window panes, the performance of this window vacuum will make the price tag seem like a joke!

The battery life lasts for about 25 minutes.

The USB charging unit is conveniently compatible with most smartphone charger, which we think is a nice touch.

Wastewater can be easily emptied as well, but our testers wished that the wastewater tank capacity was a little bigger.

We did also find it a bit awkward to fit the water tank onto the vacuum at times.

Weighing in at only about 700 grams, this is an extremely easy device on the hands, especially during those long window cleaning sessions.

If your budget is strong enough, this Kogan window vac will not disappoint with its excellent suction and healthy battery life.

  • Good battery life of 25 minutes
  • Affordable pricing
  • Powerful suction makes cleaning simple
  • USB Charging
  • Wastewater tank is easy to empty
  • Lightweight at about 0.7 kilos
  • Limited wastewater tank capacity
  • The wastewater tank is a little awkward to re-fit
  • Lack of accessories is disappointing

Black+Decker WW100-XE

Best Cheap Window Vacuum

Black+Decker WW100-XE

Black+Decker WW100-XE

Don’t let the low price tag fool you - this window vacuum is one of the most innovative and versatile cleaners we have seen.

The 360-degree pivoting head on the WW100-XE makes it easy to clean edges without having to give your wrists a workout!

Twenty minutes of battery life is above average for most window vacuums in Australia.

It does, however, take four hours to completely recharge once drained.

One good thing about the recharging is that this window vacuum supports USB charging, meaning it is compatible with most smartphone chargers!

Given the budget status, however, we have to point out that the suction on this vacuum is not as powerful as the more expensive window vacuums we have reviewed.

Also, the wastewater tank is small at 0.1 litres!

A suction squeegee attachment with this window vac will allow you to suck up spills effectively off kitchen counters!

A lightweight design of only about 1.2 kilos makes this window vacuum a treat to use.

Despite some drawbacks, the WW100-XE is a solid option for homes that are on a tight budget!

  • Affordable
  • Good battery life of 20 minutes
  • Suction squeegee tool
  • Rotating cleaning head
  • USB Charging
  • Lightweight at about 1.2 kilos
  • Wastewater canister capacity is only 100 ml
  • Suction power could have been better
  • Takes four hours to recharge

What Should I Ponder Upon Before Buying Window Vacuums?

There are a few critical factors that need to be considered before making a purchase decision for your home.

A good window vacuum has a powerful battery, great suction and will not leave any streaks on your windows.

Let’s discuss the key considerations.

Battery Life

Almost all window vacuums are cordless machines that run on lithium-ion batteries.

Typically, batteries last for about 15 - 30 minutes.

Recharging Time

We find that most window vacuums take between 2 - 3 hours to recharge.

The more time it takes to recharge, the less convenient your window vacuum.


A critical factor when it comes to window cleaning is leaving the glass streak-free.

Good suction can get rid of moisture effectively, and even make your window vacuum versatile.

Edge Cleaning

The edges of window panes host a lot of dust as well as allergens.

Look out for a window vacuum with a pivoting or flexible head or powerful suction to deal with edge cleaning.


While not exactly essential, it can be helpful if there are accessories such as microfibre cloths and smaller blades.

An extension wand can be useful in reaching windows that are out of reach.


Window cleaning can take a while so you don’t want to give your wrists a workout.

Cleaning windows can be easy with a lightweight window vacuum.


We noticed that more pricey window vacuums have better suction and leave behind less apparent streaks.

At Vacuumit, our recommendation is to spend a little over a $100 to get an excellent window cleaner for your home.

Final Verdict On Window Vacuums

There is nothing quite as detestable as walking into a home with windows that are covered in dust and grime.

All of that work you put in to keep your carpets and floor tidy can be undone in a second if your windows aren’t letting any sunlight in!

If you have a limited budget to back you, consider the Kogan KAWINVACLNA which has a decent battery.

If performance is everything to you, then you cannot go wrong with the Karcher WV5 Premium.

The good battery life and ease of use of the Black+Decker WW100-XE will make up for slightly less potent suction power.

If you are tired of wiping windows, kitchen tops and bathroom tiles, then a good window vacuum will leave you wondering how you survived so long without it!
