For large windows, small panes and mirrors that you can reach from indoors, start by choosing a squeegee width to suit each surface. A wide head may be enough for large panes, but narrow areas may need a second head. If collecting dirty water is your priority, compare a standalone window vacuum with a kit that also includes pre-washing accessories; a manual squeegee does not vacuum up water. If you have several windows to clean, also consider the weight in your hand, stated battery life, how easy it is to empty and how it stores away.
If you clean both large windows and areas between glazing bars, check the width of the supplied head and whether a narrower head is compatible. UFC-Que Choisir distinguishes between these needs according to window size.
A window vacuum collects dirty water from accessible windows, mirrors or tiles. You’ll still need to pre-wash the surface, either separately or with the accessories included in your chosen kit.
If you have several windows to clean, comfort in the hand, weight, ease of emptying and how you store the rubber blade matter just as much as the stated battery life.
To choose between vacuuming, a pre-wash kit and manual squeegeeing, first decide whether you want the appliance to collect dirty water. Then check which widths you need for your windows.
Consider it if: you want to vacuum up water after wetting or cleaning the window.
Bear in mind: pre-washing is a separate step.
Consider it if: you’d like pre-washing accessories and a window vacuum in one kit.
Check: the spray bottle and microfibre cloth are included only with certain configurations, not as standard.
Consider it if: a wide cleaning head or telescopic handle suits your needs for windows you can reach safely.
Bear in mind: it wipes away water but does not vacuum it up. A handle does not make cleaning at height safe if there’s a risk of falling.
| Criteria | What to check | Who it matters to |
|---|---|---|
| Squeegee width | Measure the gaps between frames; check the supplied head and whether a narrower head is compatible. UFC-Que Choisir says a 28 cm squeegee may be enough if all your windows are large. | I have large windows and small panes, and want to cover the bigger areas without the glazing bars getting in the way; around 42 % of consumers make this a priority. |
| Effort and emptying | Compare the weight, grip and stated battery life of the specific model; also check how easy it is to access the dirty-water tank. | When I have several windows to clean, I want to avoid getting tired and empty the tank easily; this is the top priority for around 33 % of consumers. |
| Pre-washing and storage | Check whether a spray bottle and microfibre cloth are included, then see whether the squeegee can be stored upright or hung up. | If I clean my mirrors and windows regularly, I’d rather not have to gather several accessories each time, and I want to store the appliance without squashing its rubber blade; around 25 % of consumers prioritise this kind of convenience. |
A head that works well on a large window may be too wide to fit between glazing bars. UFC-Que Choisir suggests considering an additional 17 cm squeegee if your smaller panes require one.
Measure the narrowest area and check the width of the heads, as well as their compatibility with your chosen model.
You may need to buy an additional compatible head; without one, cleaning small areas may take more passes.
The stated battery life won’t tell you whether the appliance will be comfortable to hold while cleaning several windows or whether its tank will be easy to empty.
Also check the weight, handle, access to the controls and how to empty the specific model.
A standalone window vacuum collects water after you’ve washed the window; you still need to wet or clean the glass first.
Check whether the kit includes a spray bottle and microfibre cloth, or plan your pre-washing method separately.
UFC-Que Choisir notes that storing it flat can deform the rubber blade and affect how well it wipes.
Check whether the appliance can stand upright or be hung up, and whether its rubber blade can be replaced.
The WV range is worth considering if you’re looking for a window vacuum. Some models also have a head designed for small panes.
The GlassVAC configuration mentioned by Bosch combines vacuuming with pre-washing accessories and two head widths for surfaces of different sizes.
The 2-in-1 XL Telescope squeegee is a manual option for large windows that you can reach safely.
These two manual squeegees are designed for washing or wiping windows you can reach safely. They are not a substitute for a window vacuum if your priority is for the appliance to collect dirty water.

Wash and then wipe an accessible window with a single tool. The head combines a removable, washable microfibre sleeve with a squeegee blade, and the handle is telescopic.
This is a manual tool, with no stated dirty-water vacuum function. If you have small panes or need a specific reach, check the head width and the fully extended handle length before choosing.

Wipe accessible windows, mirrors or shower screens with an adjustable handle. Its stated length ranges from 36,5 to 97,5 cm.
This manual squeegee does not vacuum up water and has no stated pre-washing function. Check the blade width if it needs to fit between frames or glazing bars; the telescopic handle does not make cleaning at height safe if there’s a risk of falling.
If all your windows are large, a 28 cm squeegee may be enough, according to UFC-Que Choisir. For small panes, also check whether you can use a narrower head: the 170 mm accessory shown by Kärcher is designed for small windows, but compatibility depends on the model.
Choose a stated battery life that suits the length of your cleaning sessions, without overlooking the weight and how comfortable the appliance is to hold. Kärcher claims up to 100 minutes for the WV 6, and Bosch up to 35 minutes for the GlassVAC version mentioned. These figures apply to those specific models; they are not a guaranteed duration for every use.
A tank that’s easy to remove or open makes it simpler to empty after cleaning. UFC-Que Choisir recommends checking this, and Bosch lists a removable 120 ml dirty-water tank for the GlassVAC version mentioned.
No. Bosch warns that harsh detergents can damage its window cleaners. Check the instructions for your chosen model to find out which liquids you can use and how to use them.
No. A long reach does not remove the risk of falling. Only use these tools for windows you can reach without putting yourself in danger; risky exterior windows and working at height are outside the scope of this household buying guide.
