If you rely on traditional time-consuming window cleaning techniques then I’ve got good news for you. I’ve sourced the best battery operated window vacuums that money can buy and you can find everything that you need right here for streak-free windows the easy way.

The added bonus of using a window vacuum cleaner is that it can take away built-up condensation on windows. Neat huh?

WINDOW-VACUUM-CLEANER-7

Before you rush out and buy a window vac you need to separate the good ones from the bad. What should you look for? First and foremost, you need a unit with a decent battery operating time and shorter charging times. Look for machines with a minimum running time of 25 minutes.

The next thing you need to think about is the cleaner head shape and if it has been designed to reach the tight corners of window frames. If not, does the appliance come with extra accessories to handle awkward nooks?

The last thing you want to consider is your budget and if it can stretch to buy a premium appliance. My advice is that if window cleaning is going to be a regular occurrence then it’s worth investing in a good quality gizmo, especially if your house has a lot of windows, glass doors or a conservatory. That’s a lot of glass to keep clean and you need a unit that can cope with the workload!

Without further delay let’s take a look at the best window vacs available to buy today. We’ll start with the highest performing gadget and work our way down:

1. KARCHER WV5 PREMIUM 2ND GENERATION WINDOW VACUUM CLEANER

If you’re after the best of the best, the Karcher WV5 Premium window vacuum cleaner is leading the race. Its a great lightweight all-rounder weighing just 1.1 kgs or 2.4 Pounds.

Karcher-WV5-Premium-2nd-Generation-Window-Glass-Vacuum-Cleaner

It operates non-stop for 35 minutes and is supplied with a cleaning fluid, a 170mm suction nozzle to reach awkward corners and edges and a microfiber cleaner head. Karcher is a German brand that manufactures appliances to an exceptionally high standard.

Why should you buy the Karcher WV5? It cleans windows fast, including shower screens and mirrors. The unit can also remove condensation and pick up spills. Karcher has built this product to provide optimum results for tasks that would normally take much longer to complete. The WV5 is a comprehensive window cleaning solution that cleans and dries surfaces in next to no time.

This model comes with the guarantee of clear-view windows when used with the branded cleaning fluids, however, many users have reported that the product can be used with any non-branded window cleaning fluid for the same results, which could work out to be cheaper in the long run.

Next up is the Leifheit 51107 window vacuum with an extended running time of up to 45 minutes and fast battery charging. It is one of the lightest window vacs weighing a mere 739g or 1.6 Pounds

Why should you buy the Leifheit 51107 window vac? It’s incredibly efficient at removing water and condensation from windows and it can get into nooks that would normally be difficult to clean.

Owners of the Leifheit 51107 are satisfied with the product’s cleaning results and have left plenty of positive reviews, however, some owners have reported that the cleaner head can occasionally find it difficult to reach into window edges.

The Leifheit cleaner costs a bit less than the leading Karcher WV5, however, you will need to pay extra for some of the attachments. I’d advise purchasing the optional click-system telescopic handle that extends the reach of the unit to enable the cleaning of conservatory roofs and windows that are higher up.

3. KARCHER WV2 WINDOW VACUUM

The Karcher WV2 is the smaller brother to the WV5 at the top of our list. The compactness of the unit doesn’t compromise its performance, this little guy is powerful. As far as weight goes, the unit weighs 1kg or 2.2 pounds and it gives a total running time of 25 minutes.

KÃrcher-WV2-Window-Vacuum-cleaner-5

Why should you buy the Karcher WV2? Often, the best things come in small packages and the WV2 is one of them. This gadget is smaller, therefore, easier to clean with. Streak-free results come as standard. You will find a generous supply of accessories including a narrow cleaning head, wide cleaning head, cleaning fluid, microfibre cloth and a spray bottle.

Its 10% smaller and lighter yet it still performs at a high level and gives an impressive finish that you would normally expect from a bigger appliance. The Karcher WV2 excels when it’s needed to reach tighter spaces that larger units would struggle with, such as decorative glass panels found on entrance doors.

The only drawback of the WV2 is a shorter running time of 25 minutes, however, the battery charge time is much shorter than the WV5 and as a result, you can get on with the job with minimum disruption. You should be able to clean multiple windows throughout your home with little hassle. Similar to its big brother, the Karcher WV2 has enjoyed plenty of positive feedback from satisfied owners.

5. Alfawise WIN660 Magnetic Window Cleaning Robot?

If you want to automate your window cleaning rather than doing it yourself why not get a robot to do it for you? The Alfawise WIN660 magnetic window cleaning robot cleverly cleans windows of all sizes. The remote control supplied can be used to guide the robot if you need it to clean specific areas.

Alfawise-WIN660-Window-Cleaning-Robot-Magnetic-Vacuums-Robot-Smart-Window-Cleaner

It does need help when it encounters different surfaces such as rubber edges, therefore, the unit will stop because of the resulting friction. Overall, the robot is perfect for small cleaning tasks and the performance is fairly consistent, although sometimes it doesn’t follow a specific cleaning routine and will clean randomly, however, it gets the job done to a high standard.

The inbuilt safety system is designed from German technology to ensure that the Alfawise WIN660 robot stays attached to windows throughout the cleaning process. The robot is equipped with a back-up power mechanism which enables the unit to remain safely attached to glass for approximately 25 minutes without a power source.

If the robot accidentally loses suction and falls from the window, it comes with a strong safety rope to catch it and avoid damage to the appliance. The Alfawise window cleaning gadget comes with onboard sensors to keep you updated on the robot’s status. It uses a combination of audio signals and warning lights to grab your attention if the robot gets into trouble.

The Fengrui R-C901 is another window cleaning robot that helps to keep the glass around your home spotless. Using a robot saves time and cost, thus, you won’t need to fork out money for a professional window cleaner. On top of that, it’s much safer to send a robot up high reaching areas rather than climbing up a ladder to do it yourself.

FENGRUI-R-C901-Smart-Magnetic-Window-Cleaner-Robot-Automatic-Infrared-Remote-Cleaner

When placed on a window, the Fengrui R-C901 will initially work upwards then change direction from left to right. It achieves over 99% coverage which is impressive for an automated cleaner. It comes with an extension cord that measures 5 meters, therefore, enabling the robot to clean glass in high places.

Once placed on a window the R-C901 robot stays firmly fixed to the glass to carry out its task. You don’t need to constantly monitor the machine, simply set it up and let it do its thing.

The unit can clean various types of smooth surfaces and is suitable for all types of glass including mirrors, glass tables and doors.

What Should You Consider When Buying a Window Vac?

Window Vacuum Type

Conventional Handheld Window Vac– these models are similar to standard handheld vacuums and share the same dimensions but the difference is that they are designed to lift moisture and dirt from windows without causing smudges or streaks. Rather than using a motorised brush, the unit focuses its suction to suck up dirty water and ensures that nothing is left behind.

Leifheit-51107-Click-System-Window-Cleaner-Tool-Kit-with-Vacuum-Squeegee

Telescopic Window Vac– The cleaning process is identical to handheld units, however, this variant is equipped with an extendable handle to clean windows on higher floors that would normally require a ladder to reach. These units provide the convenience and safety of cleaning high reaching areas from the ground level without causing any undue strain to the user.

Robotic Window Vacs– These have got to be one of my favourite appliances because I love automating domestic chores. This hands-free gadget simply needs to be placed on the glass and it will give you streak-free windows. All you need to do is pour cleaning fluid into the machine, attach it to the safety rope and press the start button. These units do require some supervision, however, if the robot runs in trouble it will alert you.

Window Vac Water Tank

Window vacuums house a water tank that collects dirty water and condensation and stores cleaning fluid. The tank needs to be big enough to pick up fluids without distracting you partway through the job to be emptied. The average tank size of a window vac is between 100ml to 300ml although larger models often come with larger capacities.

WINDOW-VACUUM-CLEANER-5

How High Are Your Windows?

Windows higher up are not easy to clean as they need you to get onto a ladder, however, it’s very uncomfortable trying to balance on a ladder and clean at the same time. A telescopic handle is the best solution to reach distant windows. Wherever possible, you should opt for a window vacuum that comes with an extension attachment or the option to buy one in future should it be required further down the line.

Window Vacuum Nozzle

The nozzle usually has the dual function of vacuum and squeegee. All you need to do is squeegee the glass whilst the vacuum collects the water into the tank.

The size and shape of the nozzle are hugely important as they determine the cleaning efficiency of your unit. A slim nozzle is great for targeting smaller areas such as bathrooms or front door windows. If you need to clean bigger areas such as glass doors then it’s best to buy a window vacuum cleaner with an interchangeable nozzle, therefore, you can swap between slim and wider nozzles. You will get through tasks quicker with the right nozzle.

BLACK+DECKER-BDH100WW-Powered-Window-Vacuum

How Heavy Is the Window Vac?

The weight of the unit needs to be comfortable enough for prolonged use if required. Remember that these units are used with just one hand, therefore, you want yours to weigh 1.1kgs (2.4 Pounds) or less.

Can The Window Vac Be Used Indoors and Outside?

In addition to indoor use the majority of window vacuums can be used outdoors as well, however, if you’re after a robot vacuum that can clean exteriors windows make sure you check that its designed for outdoor use. It needs to be waterproof and able to withstand the elements, especially if you live in an area that always rains like I do (sigh).

Handy Tips

Don’t panic if your window vacuum starts to leak whilst in action. The best thing to do is check the tank as it might need emptying. If the leaking persists, even when the tank is not full, then you should contact the manufacturer.

WINDOW-VACUUM-CLEANER-9

Similar to a standard vacuum, your window vac will emit some noise from the motor. Be sure to check the product specification for the audible decibel levels before purchasing, if your concerned that the noise might disrupt the people around you.

Be sure to clean the nozzle frequently, preferably after each use, to stop debris from passing back from the nozzle to the glass.

Features To Look Out For

Window Vac Accessories

Most windows vacuums come with a decent kit of accessories for different tasks. As a rule of thumb, make sure you get one with interchangeable cleaning heads for both small and big windows. Most models will come with a spray bottle and microfiber pads to get rid of debris whilst achieving a clear-view finish.

Karcher-WV5-Premium-2nd-Generation-Window-Vacuum-Cleaner

Power

Portable window vacuums generally run on rechargeable batteries and the operating times are usually around half an hour. This might not seem like a long running time, however, the appliances are optimized to clean multiple windows in very little time. You can clean both sides of glass door in under 5 minutes. When the battery runs flat simply recharge it with the supplied
AC power adapter or micro USB depending on the model.

Extendable Attachment

As mentioned earlier, a telescopic attachment is a must-have for a 2 or 3 story home or dwelling with glass roofs. It’s much safer and convenient to use an extendable handle for high areas and tall windows instead of attempting to use a ladder. I recommend measuring the highest point that you intend to clean and check that the tool can extend to that point.

Battery Charge times

The battery charge times varies between models. High-end window vacuums are usually equipped with a fast charging feature to minimize delays when you’re carrying out bigger jobs such as spring cleaning.

Window Vacuum Pricing

Premium models normally come with longer running times to help you clean several windows in one go, however, you will need to shell out a bit more money for these although they are still very affordable for most budgets.

WINDOW-VACUUM-CLEANER-1

Wherever possible, try to buy a window vacuum cleaner that comes as part of a kit, therefore, you will be supplied with a good range of accessories to tackle multiple tasks. premium models are approximately priced between $100 to $199 and robotic window cleaners are around the $150 to $220 price point.

Other Useful Information about
Window Vacuums

  • More than just window cleaning you can use a window vacuum on mirrors, shower screens and tiles.
  • These gadgets are particularly good at getting rid of condensation from bathrooms.
  • Always ensure that the appliance is fully charged prior to using it.
  • If your windows are particularly grimy you will need to apply a detergent to clean them before using the vacuum. Most window vacuums are supplied with a cleaning fluid and spray bottle for this.
  • For best results, spray some cleaning fluid across the whole window and spread it with a microfiber cloth or squeegee then clean in a downward direction with your window vacuum. Job done!

Frequently Asked Questions

Ques. Do all window cleaning vacuums come as part of a set?

Ans. Unfortunately not. Some brands provide the basic unit, therefore you will need to buy additional accessories as optional extras. These units are often cheaper, however, I think it’s worth buying a window vacuum with a range of accessories to handle different tasks and various sized windows.

BLACK+DECKER-BDH100WW-Powered-Squeegee-Window-Vacuum-Cordless

Ques. What’s the benefit of a robot window vacuum cleaner over a manual one?

Ans. Robot units provide a good level of automation, therefore, you can set it up and leave it to clean while you get on with your day although I’d recommend checking on the machine periodically. I’m a big fan of automated domestic cleaners and you’ll see that I’ve written plenty of reviews about robot vacuums throughout this site. Robots are not perfect but manufacturers are constantly improving them and the biggest advantage of owning one is the time that it frees up.

Ques. What type of cleaning fluid can I use with my window vacuum?

Ans. I’d always recommend using a window cleaning solution because the mixture is made to stop streaks. As mentioned earlier, some models are supplied with cleaning fluid, however, once that runs out you can purchase any type of window cleaning fluid of your choice.
