Bosch Cordless Window Vac GlassVAC | for windows, tiles, mirrors and shower, running time: approx. 35 windows

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.

This is an excellent machine cleans very well and leaves no marks or smudges. Not too noisy and keeps battery for a long time too. Used it on house windows internally and it’s made them look brand new after years of being unable to get rid of smudges. Excellent value

Really handy device that makes cleaning glass and smooth surfaces quick and easy. It’s not 100% streak-free, but it does a good enough job for everyday use. I’ve ended up using it everywhere on shower screens, bathroom mirrors, kitchen tiles, and even the cabinet doors. It’s lightweight, charges quickly, and makes the job so much less effort. Would recommend if you’re after convenience over perfection

This is so much better than the other main manufacturers Works easily and instant results Shower or windows it works so well

It was grat and easy to use the price and qwality is next to nun I've been looking for a while and IM getting my windows nice and clean now it's so easy to use and it levels no streeks excellent qwality good idea

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.

I am a window vac addict, I just love them and I have always used the Kärcher one. I honestly got a bit peeved, because they don’t last long, my record is my last one, just over 2 1/2 years, with use every day, sometimes twice a day for cleaning/ drying walk in large shower and cleaning windows, inside and out. I thought this time I would try something new and after some research, I decided on this one. I have only used it a few times but I do say, it seems better than the Kärcher. It sucks up better, leaves NO streaks, people saying it streaks, if you read the instructions it will tell you that you are applying too much pressure or too little, just get to know it and it literally is streak free. It’s more chunky than the Kärcher and seems to hold a lot more in its water container. I like the feel of it and the ergonomics of it. Because I have had so many over the years I can give you tips on how to make these things last longer. * Empty the water container frequently, don’t let it get full at all, just keep stopping and emptying it, this stops the water backing up on itself and going into the motor, that is what will kill these things. * Also try to keep it upright, I know this one says you can go in any direction and you can and it’s great while doing so but ONLY IF YOU HAVE EMPTIED THAT WATER OUT OF IT FIRST. * Don’t let the battery get completely empty before charging. * Don’t keep charging it until the battery is full every time, charge it after you have used it 3-4times * Don’t rest the blades on anything that can ruin the rubber on them, I stand it upright with the stopper left open, so it can dry out fully between uses. Also if you register this product on Bosch website you will get a 3 year warranty on it. So far, I love it better than Kärcher but I will update with how long this one lasts and if Bosch honours the warranty if it goes before the 3 years are up?

Cleans windows quickly and is easy to use, but it does leave a few streaks. Still, I’m happy with it and it saves a lot of time.
