Best Window Vac in the UK (2018): Reviews and Buyer’s Guide

Written by James Hall | 1 Comment| Last Updated: November 8, 2018

Looking for a window vacuum for your windows, mirrors or tiles? In this article, we've listed five of the best window vacs of 2018 - along with mini-reviews to help you choose.

Our list of the best window vacuums

Window vacuums have grown in popularity in recent years, as they allow you to clean windows and other flat surfaces much faster than traditional methods. If you're tired of wiping down windows and still getting a streaky finish, a window vac could be a great choice.

This type of vacuum isn't just for windows though. They can also be used for removing condensation. If you have a damp problem in your home, this is one of the fastest ways to remove excess moisture.

With a variety of window vacs on the market - often with almost identical designs - it can be difficult to choose the right option. That's why we've put together a list of the five best window vacs in the UK. We've also included short window vac reviews to help you make the right choice.

What to Look for in a Window Vacuum?

Before we get to the recommendations, here are some of the most important factors when choosing a window vacuum:

  • Run-Time. Most window vacs are cordless, which means they are powered by a rechargeable battery. Run-times typically range from 20-45 minutes. Make sure you choose a model that provides enough time to clean all your windows, shower doors or whatever you want to use it for without needing to be recharged.
  • Cleaning Performance. Like all window cleaning equipment, the best window vacuum cleaners should clean quickly while leaving a streak-free finish (or at least close to streak-free). The vacuum should also be powerful enough to remove moisture efficiently.
  • Edge Cleaning. It can be difficult to clean along the bottom edge with some window vacs, due to the shape of the machines. Look for a model that makes it easy to clean the entire window.
  • Accessories and Tools. A window vac may come with extras such as a smaller blade (for cleaning in corners), microfiber cloths and detergents. While these aren't essential, they can make cleaning much faster.
  • Weight. Cleaning large windows can be tiring - especially with a heavy cleaner. This is why many window vac manufacturers go to great lengths to ensure their vacuums are lightweight.
  • Value for Money. Window vacs are small, so they don't cost as much as a full-size vacuum cleaner. They still range from £20 up to £100+ for professional models though. Aside from cleaning performance, make sure you buy a vac that suits your requirements without overspending.

1. Kärcher WV2 Premium Window Vac

Our top pick for a window vac is the excellent Kärcher WV2 Premium. It's a rechargeable cordless model with a decent 25-minute run-time and excellent performance on a variety of surfaces. If you need a window vacuum for all-round cleaning on mirrors, tiles, windows and even floors, the WV2 is the one to go for.

The Karcher WV2 is our top pick for a window vac

Kärcher WV2 Premium

Our Rating:

  • Streak-free cleaning
  • Lightweight design & comes with cleaning kit
  • Lithium-ion battery with 25 minute run-time

Kärcher are kings of the non-professional window vac world - and the WV2 Plus is our favourite model. It's been significantly upgraded compared to the previous Kärcher window vac, including a 10% shorter length, longer 25 minute run-time and lightweight design. This allows it to clean up to 75 square metres on a single charge - which should be more than enough for most small jobs.

Kärcher has included a cleaning kit with the vac (as long as you buy the Premium version). This includes a detergent for cleaning windows and microfiber head to avoid scratches. You also get a small suction blade with the vac. This is great for getting into window corners or other tricky places, so I recommend spending the few extra pounds on the Premium version.

Most importantly, it's an excellent window vac for getting rid of water marks and condensation on windows without leaving streaks. The design also makes it simple to use for clearing up small spills.

Overall, the Kärcher WV2 Plus ​takes a bit of practice use properly, but once you get the hang of it is great for cleaning windows, shower doors and other flat surfaces. It's relatively expensive for a window vac - but justifies the price by making everyday tasks easy and even enjoyable. Click here to view its price.

2. Kärcher WV5 Premium Vac

The next model up from the WV2 is the handheld Kärcher WV5 window vac. It's more expensive than its smaller sibling, but has a longer run-time and is designed for semi-professional use. If you need to clean larger windows without recharging then it's a great choice.

Note: For more information about Karcher window vacs, check out our reviews page.​

The WV5 is a step up from the WV2 in both features and price

Kärcher WV5 Premium

Our Rating:

  • 35-minute run-time
  • Includes narrow cleaning blade & cleaning kit
  • Removable battery

The WV5 shares many of the same features as other Kärcher window vacuums. These include streak-free cleaning, 3-step LED display for battery life and a cleaning kit.

The biggest differences between this model and those not meant for professional use are the run-time and removable battery. With a 35 minute battery life and ability to clean 105 square metres on a single charge, the WV5 is worth the extra money for cleaning large areas. Being able to purchase additional batteries and swap them can also increase its run-time almost indefinitely.

It also comes with a narrow cleaning blade, for easier cleaning in corners, ​and a microfiber cleaning head. A minor downside is that it takes around 70 minutes longer to charge.

Despite these small issues, the WV5 Premium is an excellent window vacuum that's great for bigger jobs.​ If you have a large house or just want a longer run-time, it's worth spending extra and getting this instead of the WV2. Click here to view its price.

3. Bestek Telescopic Window Cleaner

A cheaper alternative to Kärcher window vacs is made by Bestek. With a 30-minute run-time, it can last long enough to clean the windows of almost any home. It also provides decent cleaning performance and suction power - especially considering the price.

Bestek Cordless

Bestek Telescopic Window Vac

Our Rating:

  • 30-minute run-time
  • 10" - 40" extension set for adjusting height
  • Cheaper than the Karcher vacs on this list

The first thing that stands out about the Bestek is its battery run-time. With a charge that lasts 5 minutes longer than the Kärcher WV2, despite being cheaper, it's one of the best window vacs in this regard.

It also comes with a selection of useful tools. These include a spray attachment, squeegee and crevice tool. The telescopic extension is great for when you need a little extra reach - and there's even a dust filter included for cleaning keyboards.

Most importantly, it does a great job of cleaning windows without leaving smears. The combination of spray tool and cloth makes quick work of dirt and grime, while the vacuum quickly removes remaining liquid without leaving smears.

As you would expect from a relatively cheap model, there are a few drawbacks. Like many window vacs, the Bestek cannot be used upside-down as water may leak. This can make it difficult to clean the bottom of windows due to the sills getting in the way. It can also be hard to see whether the removed water reservoir is filling up.

Even so, the low price and solid performance of the Bestek window vacuum means it's worth considering.​ Click here to view its price

4. VonHaus 15/050 Window Vacuum

Another budget window vacuum is the VonHaus 15/050. It's a rechargeable cordless model that provides convenient cleaning and a 25-minute run-time. While it doesn't quite have the quality of the Kärcher models, it provides excellent value for money.

The VonHaus is one of the cheapest window vacs

VonHaus 15/050

Our Rating:

  • Great price
  • 25-minute run-time
  • Includes microfiber pad

With its lightweight cordless design and 25 minute run-time, the VonHaus window vac is well-suited for cleaning glass around the home. It also comes with a microfiber pad and spray bottle to help achieve a sparkling finish to your windows.

​A downside is the VonHaus can't be used in all directions as it starts to leak. This is a big drawback compared to models such as the Leifheit (which sadly is not available at the time we last updated this article). We also don't think it provides the same level of streak-free cleaning as the other models on this list.

Considering it has a shorter battery life than the Bestek and can't be used at all angles without the water leaking, it's difficult to recommend the VonHaus as a budget window vacuum. If you can find it on offer, however, then it might be worth picking up as it still does a decent job on windows. Click here to view its price.

5. Vax VRS28WV Window Vacuum Cleaner

One of the most innovative window vacuums on the market is the Vax VRS28WV. Unlike other models, which have a fixed cleaning blade, the Vax pivots to make it easier to clean edge-to-edge without turning it. It also has a 30-minute run-time and stylish design.

The Vax has a pivot design for easier cleaning


Our Rating:

  • Pivot design for easier edge cleaning
  • 30-minute run-time
  • Includes microfiber pads

Along with the pivot design, the Vax window vac is built with two tanks for improved cleaning performance. It also comes with microfiber cleaning pads and a glass cleanser for a shiner finish.

Unfortunately, the Vax has some drawbacks. The suction doesn't seem to be as powerful as other windows vacs, so it doesn't provide the same cleaning performance. The pivot head - while an excellent feature in theory - is too stiff to use comfortably.

If the Vax VRS28WV was more powerful and the pivot head easier to use, it would be much higher up this list. In its current state, we can only recommend it over other options if you desperately need the pivot feature. 


Window vacuums can be a great tool to have around the house - especially if you're tired of manually wiping windows, shower doors and other flat surfaces. While they usually don't leave a completely streak-free finish, the best window vacs do the job in a fraction of the time.

Our top recommendation is the Kärcher WV2 Premium. It provides great cleaning performance, along with a useful smaller blade for cleaning corners. If you need a longer battery life, the WV5 Premium is a semi-professional model that also comes with a removable battery. And if you want a cheaper option, the Bestek Telescopic is an excellent alternative.
