Best Window Vacuum Cleaner 2019

Window vacuums are a quick and efficient way to remove moisture from large areas of glass. For instance, if you have just washed your conservatory or windows, had a shower and the screen is wet, or you have a build up of condensation, one of these surface cleaner appliances can vacuum up the excess liquid.

Not only does this make drying quick, but it won’t leave streaks and is much more efficient than using a towel. Removing the moisture is important to avoid a build-up of mould and keep the air in your home clean.

Best Window Vacuums

Kärcher Window Vac WV2

A package complete with everything you need to get going, this updated Karcher WV2 has been awarded our best window vacuum title after reviewing.

There are two suction heads included, which makes it perfectly switchable between shower screens, various outside windows and those little kitchen floor spills. Just use the larger one on bay windows and conservatory panes, and the smaller one on the glass in your front door or any smaller panes.

You also get a microfibre cloth attachment with an extra spray bottle, in case there are some stubborn stains to remove beforehand, and you don’t want to have to bring out various cloths and brushes to try and clear it. Perfect for cleaning your car and removing any marks which have ended up on the windscreen before you get the bucket and sponge out.

It is easy to grip, and the on/off switch is easily accessible which makes control so much easier. There is also a little LED light which tells you how much power is left in the vacuum so you won’t risk getting halfway through a job before it surprisingly cuts out.

To empty, simply un-attach the secure plug and allow the dirty water to flow out. The rubber lip on the suction heads is removable if it needs a bit of a clean between uses, so no dirt is transferred on to your windows.

For what you get in the bundle, the price is pretty good and cheaper than buying everything separately. And when comparing to the other Karcher’s in the range, it is definitely the one where you get the most for your money.

We like

  • Three attachments
  • Easy to empty
  • Easy to manoeuvre

We dislike

  • Some full charges didn’t last the entire 25 minutes

Final Verdict

For removing excess moisture in your home, this is one of the best Karchers and window vacs on the market and the price is pretty decent.

PIFCO P29013 Streak Free Cordless Window Vacuum

Another budget buy, which makes it quick to get rid of condensation.

It is one of the most slimline we reviewed, so perfect for anyone who struggles to grip handheld devices. There is no bulkiness or overly large handles, and the water container is flush against the vacuum so doesn’t create any unnecessary awkwardness.

You get a cloth pad and spray bottle with every purchase to make the cleaning part easier and more hygienic as the fibres will lift and trap any excess dirt rather than spreading it all.

We would say it is the least powerful of those we reviewed, so is definitely not one for heavy-duty tasks and areas. It also left the most streaks, so if you aren’t prepared to adjust, adapt and practice your technique, then it may cause you to give up before you’ve barely started.

We like

  • Price
  • Shape easy to hold

We dislike

  • Not the most effective
  • Weak suction in high-problem areas

Final Verdict

It is one of the cheapest though, so if the lightweight and slimline design are one of your biggest concerns, then it would be worth giving a go. Stick to shower screens.

+ Specifications

  • Weight: 0.78 kg
  • Dimensions: 16 x 28 x 32.7 cm
  • Battery Life: 25 mins
  • Charge Time: 120 mins
  • Width Of Suction: 250 mm

AEG WX7-60V1 Window Vac & Hard Surface Cleaner

One of the best if you want to be able to remove moisture from several flat surfaces and not just your windows, the newest AEG window vac has your back.

Whether it be windows and glass, mirrors, kitchen and bathroom tiles, shower cubicles and screens or even tables and hard floors, it is up to the job. Say you’ve just mopped the kitchen floor, and the kids are causing trouble as they want to go and get a drink but you won’t let anybody walk on it, and the dog is probably going to go and mess it all up anyway. If you use this vacuum after mopping, it will be dry in minutes. No dirty marks or accidents caused.

Because it runs for a great 60 minutes in one charge, the whole lot can be done before any of your family even noticed the bucket was out in the first place.

The 290mm blade makes it great for larger surfaces, and you can also use whatever method you like – it will accommodate the movement. Whether you’re all about the professional S-shape or up and down, it is easy to handle and won’t leak or spill water.

There is the option to buy on its own or with a spray bottle and cleaning pad, but the latter option isn’t much more so even if you only use it every so often, it is still worth that little bit extra.

We like

  • Run and charge times
  • No-leak protection
  • Well-built

We dislike

  • Difficult to get into the bottom of windows as tilting it means less suction

Final Verdict

The added spray bottle is a handy help, and it was much better than we expected.

+ Specifications

  • Weight: 0.78 kg
  • Dimensions: 14 x 19 x 28.5 cm
  • Battery Life: 60 mins
  • Charge Time: 120 mins
  • Width Of Suction: 290mm

AEG WX7-60A Rechargeable Window Vacuum Cleaner

One of the cheapest window vacuums on our rundown but still does the job well enough to make your life easier.

First of all, and the thing that surprised us the most, is that despite its price and size, there is a very generous runtime of an hour maximum on just two hours charge. This even puts some of the big-name best-sellers to shame.

It is lightweight, and there is a soft touch handle too, so it doesn’t start to feel uncomfortable after a long period of use. Four colours are available which makes a nice touch, also.

There is the option to purchase it with an added spray bottle and pad for doing the cleaning, but if you already have your set method, then it is not a must. We would like the head to be replaceable with a shorter version as it can’t be used on small windows (such as door panes), but for larger windows, it cuts cleaning time right down.

A newer version, the WX7-60V1, is available but there aren’t many huge differences apart from that it is a bit lighter – this remains a sufficient budget option if you’re just looking for a cheap and cheerful window vac.

We like

  • Long run time
  • Choice of colours
  • Short charging time

We dislike

  • No option for different sized blades

Final Verdict

For a budget pick, it performs well and is a great item if you want to see what the fuss is about.

+ Specifications

  • Weight: 1.1 kg
  • Dimensions: 14 x 19 x 28 cm
  • Battery Life: 60 mins
  • Charge Time: 120 mins
  • Width Of Suction: 290mm

Leifheit Window Vacuum Cleaner

One of the fastest we reviewed when sucking up any water or condensation.

It can be used at any angle, from upside down to get to the bottom of the vertical window to horizontally for skylights and indoor conservatory roofs.

To keep the battery in working order, it will automatically enter standby mode when on but not in use. According to advice in the user manual, you also have to store it fully charged, so be aware of this before popping it away to keep the battery life strong.

There is the option to purchase it with an extra pole which can extend the usability if you have any hard to reach high areas. The pole simply inserts into a hole at the bottom of the vacuum and fits securely.

We like

  • Quick and powerful
  • No dripping or spilling when tipped/angled

We dislike

  • A lot of work to keep battery in order

Final Verdict

Overall, it is worth the price. Simple and basic, but does the job.

+ Specifications

  • Weight: 0.73 kg
  • Dimensions: 15 x 31.5 x 28 cm
  • Battery Life: 35 mins
  • Charge Time: 180 mins
  • Width Of Suction: 280mm

Vileda WindoMatic Power Window Vacuum Cleaner

This updated version of the original WindoMatic offers something for those of you out there who have a considerable build-up of condensation and find it takes a little while to get the job done, or who have a lot of difficult corners to reach.

Featuring two settings, the maximum boost function can give you 50% more power, reducing the likelihood of streaks and amount of time you spend collecting it all. The neck and head are also tiltable with pressure, allowing you to clean those harder to reach places and any corners, which is handy when compared to a lot of other models which only remain straight.

Because the blade is quite thin, it can go right up to flat bases such as window frames and shower screen frames which is good for getting those pooled water layers up without getting a cloth out.

Running time is generous, and the length of the blade is suitable for any surface big or small. The handle is a good thickness to hold, and it doesn’t feel too bulky or difficult to navigate which is good.

Our only gripe is the positioning of the two power buttons, as when we gripped it our thumb tended to press the off switch a few times. But it is just a matter of training your grip and finding the best for you.

You don’t get any extras such as other blades, which could put you off if you think they’d be handy, but if you’re just after a window vac which is up to the regular job, then it is a great choice.

We like

  • Good shape to hold
  • Thin head makes edges easier

We dislike

  • Would prefer a selection of accessories to be available

Final Verdict

The price is good, and the two suction modes should help you cover your entire home no matter how hard the task.

+ Specifications

  • Weight: 0.64 kg
  • Dimensions: 32.2 x 17.8 x 11.8 cm
  • Battery Life: 40 mins
  • Charge Time: 180 mins
  • Width Of Suction: 270mm

Kärcher Window Vac WV 1

Taking the Karcher range right back to basics is the original WV1.

It is a standalone window vac, with one suction strip and no fancy extras.

At 550g, it is one of the lightest window vacuums available which is good for anyone who struggles to grip and manoeuvre handheld appliances. It is small too, and pretty quiet in operation, so ideal for those more difficult areas.

Unlike with a few of the later models, the water tank is removable for emptying rather than there being a stopper which unplugs, which we actually like as it kept everything more separate and defined, and a bit less messy once you get the hang of it. It also makes it a bit easier for using upside down or on its side, as the water doesn’t drip out or slosh about as much.

It can be used with the dedicated extension pole from Karcher, to reach any higher areas or floor to ceiling windows. Getting into corners or right up to frames is a bit difficult, but nothing a little wipe around with a cloth afterwards won’t sort if you’re happy to do so.

The price reflects what you get. It is around half of the others in the range, so one of the best cheap window vacs you can purchase. But if the others are ever on offer (which they usually are), it could be worth laying down a few more notes for the additional attachments you get.

However, if you only have a few little windows to clean or it will be reserved for the shower then it is entirely up to the job, and worth sticking with the leading brand.

We like

  • Clears condensation well
  • Lightweight

We dislike

  • Can be fiddly to remove and refit the water tank

Final Verdict

The original Karcher, so it is missing a few of the later models' specs, but for the price they could be worth living without.

+ Specifications

  • Weight: 0.55 kg
  • Dimensions: 13 x 25 x 27.5 cm
  • Battery Life: 20 mins
  • Charge Time: 120 mins
  • Width Of Suction: 250mm

Bosch GlassVac Cordless Window Vacuum

Don’t be put off by the beast-like shape and stature of this window vacuum; it is simply a signal of how good it is.

With the purchase, you get two sizes of rubber wiper blades and a spray applicator and microfibre cloths.

There are also a couple of little extra touches – a wrist strap will keep it in place when it is in use, which is great for anyone with an unpredictable grip or who may be working in an unsecured area such as up ladders. Emptying the dirty water is easy and mess-free, as you just unplug the stopper and it all flows out.

An integrated LED light displays how much battery is left so you won’t be caught running out when you’re halfway through a window (which would result in a very unusual mark and pattern). When the time comes to recharge, just pop the included micro USB cable into the slot and leave it to work its magic.

We like

  • Good power and suction
  • Holds power well
  • Strong build

We dislike

  • Plug is stiff when new for first few uses

Final Verdict

Great charging and run times. If the Bosch range has already won you over in other areas of the home then you won't be disappointed in this little device.

+ Specifications

  • Weight: 0.7 kg
  • Dimensions: 16.3 x 9.6 x 20.3 cm
  • Battery Life: 30 mins
  • Charge Time: 180 mins
  • Width Of Suction: Large 266mm, Small 133 mm

Kärcher Window Vac WV5 Premium

The newest Karcher window vac on the market, with a lot of little handy updates which may sway you to splash the cash.

To be fair, we say ‘splash the cash’, but the price is actually very reasonable for the latest model, so is well worth it. You get the ordinary large blade, as well as a smaller option for those little windows and shower screens, plus a microfibre attachment with an extra spray bottle for those pre-wash needs.

Now for the WV5-specific features. On the main blade, you have an adjustable distance roller feature. This means that the side guides can be extended slightly to reach into the corners. A lot of other window vacs will only reach so far up to the edges of the window panes before you inevitably have to give the rest a little wipe with a cloth, but this solved that issue.

It runs for the longest time compared to the others, allowing you to tackle an area of around 105m2 before running out of battery. Charge time is considerably longer, but as long as you prepare for this, then it shouldn’t be a problem.

The battery is also removable for charging, so a) you don’t have to plug the entire machine into charge and b) there are replaceable batteries available, in case you just can’t wait for it to recharge and love a good old hour-long window cleaning session.

It is a bit bulkier than the other options on the market, but it still isn’t ridiculously cumbersome. Using it took a few goes to get right, and leave everything completely streak-free, but once you have mastered this, then it is easy to repeat.

We like

  • Instructions easy to follow
  • Straightforward to fit together and change heads
  • Long battery life

We dislike

  • Takes a bit of getting used to

Final Verdict

The later version of the WV2, and the extra boost in working time and usability may sway you to lay down the few extra notes.

+ Specifications

  • Weight: 0.7 kg
  • Dimensions: 12.2 x 18.3 x 30.6 cm
  • Battery Life: 35 mins
  • Charge Time: 210 mins

Help and Resources

Window Vacuum Cleaner Buying Guide

What To Look For In A Window Vac

  • Portability: This is essentially how heavy the vacuum is (including battery when inserted), the size and the shape. You are going to want something you can easily lift, hold and move around.
  • Run Time: This varies from model to model, but generally the higher priced vacuums will have longer running times and be able to cover a larger area in one charge. Often, the longer the running time, the longer the charge, unfortunately. A 20-minute battery life can generally cover an area of 75m2.
  • Accessories: Think about the layout of your windows and what/where you will be cleaning. Some higher-end models can accommodate telescopic handles or extension poles, and even small nozzles to get into any corners (often purchased separately). Tilting heads are also a good feature.
  • Edge Cleaning: It can be hard to get right up to the window frame or shower screen surround with some vacuums. If you don’t want to be getting a cloth out to wipe up the residual moisture, then get one which is thin enough to do this, or can be tilted.

Cost

Thankfully, window vacs don’t cost as much as the usual upright carpet versions.

They range from about £20 to over £100. The higher ones will see some accessories and could generally have better suction and ease of use, but don’t think they’re necessarily the best for your needs – think about what you need from the pointers above, first.

Also, some of the cheaper vacuums are actually underdogs, with higher run times and quicker charging than some of the all-singing-all-dancing models.

FAQ’s

What Is A Window Vacuum?

Window vacs are essentially squeegees which remove excess water from surfaces (particularly glass and tiles), but with a lot more power and without the need to mop up all the water afterwards.

They don’t actually clean your windows – you still have to do that beforehand – but they get rid of all of the after-product of the cleaning. This is important, as you don’t want the moisture to turn into mould.

It also helps it look nicer, as there are few streaks left behind compared to wiping with a cloth or kitchen paper and putting an awful lot of elbow grease into it!

Who Makes The Best Window Vacs?

Karcher is the leading brand, as shown by our reviews. Their entire power tool range is one of the most popular, so their vacuums are reliable.

Other names you will likely see are well-known brands such as Vax, Beldray, Silvercrest, Bosch and Vileda, as well as some more unknown brands like Pifco, Leifheit and Karachi.

The best vacuum for you won’t necessarily be a brand-led solution, but rather one which fits your personal wishes.

Do I Need The Extra Spray Bottle And Microfibre Pad?

This is an optional extra for some of the above window vacuums if it doesn’t come with it as standard.

It allows you to spray on the cleaning solution and rub it into the window to clean it before you use the vac, as the vacuum doesn’t actually do any of the cleaning.

They aren’t a must, as if you already wash your windows with a cloth and some solution you can just stick with this method. But it does keep everything a bit cleaner, and easier to cope with.

Which Cleaning Solution Can I Use?

Most brands have dedicated solutions in place which can be used, and are designed to work best with their vacuums. This is what we reviewed them with.

However, a lot of other users have commented that they use a simple solution of water and washing up liquid in their spray bottles – just ensure it doesn’t invalidate any warranty and you are happy to do so.
