Bosch Cordless Window Vac GlassVAC (for Windows, Tiles, Mirrors and Shower, Running time: Approx. 35 Windows, in Carton Packaging)

Great product. Does not leak.does not smear. Very easy to keep clean. Ticking all the boxes so far.

We have several Karcher equivalents and one needed replacing and decided to try an alternative brand. We have other appliances from Bosch and we generally purchase their windscreen wiper blades, so we were familiar with their ability to clean glass well. This has proved to be the case with the Glass Vac, as it definitely leaves less smears then the Karcher blades. The battery life appears to be very solid and so far on the first charge the unit has cleaned eight large bifold door panels inside and out plus twenty window panes as well as several grandson fingerprint splurges in between using the window cleaning tool supplied. It certainly is a capable machine although there are two drawbacks - the dirty water water reservoir is small and if using it to clean down a shower screen you will likely need to empty it before you’ve finished, but cleaning the slight volume of cleaning liquid used on windows is fine. Also, the handle shape has its ups-and-downs;- the short distance between the blade and the bottom of the unit makes it possible to get closer to the edges of window reveals than a Karcher, however, it’s open design and slightly heavier construction makes holding it more tiring. Overall we are very pleased with it and decided to dedicate it to the window cleaning task while the Karcher’s are doing the showers. I would buy this unit again as it appears to be more sturdily constructed than a Karcher and the release mechanism for the blade is far better, with easy release and simple cleaning procedure for the parts.

A lot of reviewers compare Bosch to Karcher window vacs, and this is no exception. This replaces a Karcher WV5, which, IMHO, is a piece of junk, having literally fell apart after 18 months. A comparison with the Karcher is probably not a bad thing. Build quality: better than Karcher, both the large and small wiper sections clip on and release positively from the body of the unit (it was the large blade assembly on the Karcher which literally fell apart in use). The Bosch rubber squeegee element is soft rubber, supported by a stronger combed plastic section. I think that design makes it more efficient than the Karcher, which with its harder rubber blade used to make a noise like fingernails scratching a blackboard when going over nearly dry glass. Personally, I have never been able to get totally streak free glass after using a window vac, and have found that a follow up buffing with a microfibre cloth is required to remove residual streak marks. The Bosch rubber blade leaves fewer streak marks than the Karcher. Edge suction: I've had no issues with it sucking right to the edge of the glass. Handling: ergonomically, I have to put the Karcher slightly ahead. The Bosch body is bit "dumpy" and not as well balanced as the Karcher, but if you haven't used the Karcher previously, it would not be an issue as it feels easy enough in the hand. Tank capacity: I've read reviews in which the tank volume has been an issue. It has not been an issue for me as I am cleaning the windows of an average size house and have only had to empty the tank twice during a whole house clean. Might be a problem if you're doing a block of flats. Emptying the tank: The reservoir section is easy to empty and to clean. On the Karcher, to empty the reservoir completely, it had to be disassembled from the body of the unit, a right faff. Battery life: As per the last paragraph, the battery lasted throughout a whole session and still had capacity to spare. Accessories: comes supplied with cleaning bottle with pads attachment, no cleaning agent included. Again, to be fair, the Karcher equivalent is better, as I found the Bosch bottle spray nozzle tends to dribble a bit regardless of the spray setting, but that is a minor niggle. I like the wrist strap attachment: useful if you've to use it for awkward windows which need accessing outside panes from inside the room. In conclusion I like the Bosch as it is well constructed, reasonably ergonomic and easy to use, not very heavy and has a decent battery life. The price seems reasonable, £56 at time of purchase. This review is based on initial impressions in Sept '20 . If it fails or falls apart, I'll edit the review.

Have to say what a game changer this is. I have small Georgian windows and to clean them inside is painful. I have contemplated purchasing a window vac for some time but could never find one with a small enough head that would fit the panes. I am so pleased with this purchase. This is amazing and fits beautifully for small windows and comes with a larger head for large patio doors. I have 16 panes per window and this makes the job so much easier.

Bought this to replace my Karcher which just stopped working & now this has as well. Despite the light turning green to say it's charged it just won't turn on. Has better suction & ability than the Karcher but sadly equally as unreliable.

Had previously briefly thought about purchasing one but thought it was just another product which was a bit of a fad and nothing a bucket and a few cloths could not handle. Saw this on offer during the Amazon Prime days and read the reviews which piqued my interest again. Was contemplating the Kracher but the numerous reviews of the short life made me lean towards the Borsch model. I have had it just a day and I have to say I have been kicking myself for not getting one earlier. The last time I cleaned the windows was such a chore. There were so many streaks and they were so difficult to get rid of. I have just cleaned the garden room bi-fold doors and windows with the GlassVAC and it was a breeze! It is quick and easy to use the spray and wipe the windows. The GlassVAC then sucks up all the water and leaves the glass mostly streak-free! I would suggest using a dishwasher rinse aid and water for the spray. It really does leave less streaks and cleans glass and mirrors well. I would also suggest having a microfibre cloth at hand to wipe the head of the GlassVAC to wipe off excess water on the head. Yes, you are not going to be able to get to bottom of the panes or sides of all of your glass or mirrors but just a quick wipe with a microfibre cloth should do the trick. You can then use the cloth to give a quick finish. It takes a fifth of the time and effort to do what was previously such a chore. A full length mirror takes a minute to clean which otherwise would have taken over 5 minutes using isopropyl alcohol, Windowlene and a couple of cloths and still not given me the desired finish. I really think it’s one of the best gadgets I have bought in the last couple of years!

The appliance itself is excellent if rather heavy to use. However, I tried several times to register the warranty but couldn't do it until I was told that it is classified as a DIY product rather than a small appliance. The five year warranty is worth going for.

I was gifted this and have to say it's amazing. I like the 2 sizes you can choose for the head and the battery life is great . We have quite a lot of condensation on some of our windows and this makes sorting it easier , plus I,m not using tea towels anymore so less washing , which is a win for me 💃🏼

ممتاز جدا جدا انصح فيه بقوة 👍

Alles bestens gewesen 👍🏻
