Struggling to see through the grime gathered around your windows? Let’s help you find the best window vac for 2019. Our reviews and buyer’s guide will ensure that this arduous task can be done in the least amount of time so that you can actually get on with the things that you love.

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.

Portable window vacuums are designed to eliminate debris and dust from window panes with minimal effort. They are thorough, efficient and can achieve great cleaning results in very little time. The added bonus of using a window vacuum cleaner is that it can take away built-up condensation on windows. Neat huh?


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:


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.


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.


The Leifheit portable gizmo ensures leak-free cleaning from any angle and as a result, skylight windows will not be a problem to clean. Gone are the days of water dripping all over you as you try to clean overhead windows.

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.

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.


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.


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.
