Bosch GlassVAC Detergent Concentrate (for GlassVAC window vacuum cleaner, for glass and non-porous surfaces, 500ml)

I hate cleaning windows. Then I bought this little beauty after seeing someone using one in a cafe. It is truly a game-changer for me, my windows are sparkling clean in no time, it's brilliant in the bathroom, on glass tops, mirrors etc. condensation on the windows in the morning is quickly vacuumed away, I absolutely love this amazing invention! The battery life is good and it recharges really quickly. It's also not heavy either which is a bonus. I later bought the small head which is good for smaller windows. It is very easy to change from the small head to the big one. Highly recommended!

Charges easily via USB / USB 3 pin adapter plug and so far the battery run time is excellent. Gets me through 3-4 days of windows and shower cleaning. Suction is good and works when inverted too which is great. The unit is very well made (it's a Bosch after all) and the integral tank design is good and is easy to empty and so far no signs of any leaks, especially when inverted, which is a real bonus.The only slight thing is that I wish they also had a smaller head attachment. For most of my windows and shower the standard head is fine, for two small window tops I have I have to develop a twisting technique for most effective use, it's not a real problem but providing a smaller head adapter (even as an extra option) would be a nice touch.I've mostly been using it to collect condensation off of my windows and tiles and clean my shower. It's been very good for that. The cleaning attachment for cleaning your windows is good too, combined with the spray bottle to mix your own solution in, it makes things easy.Charging and run time are good, mine seems to last a few days, typically cleaning 4 windows and a shower for a few minutes each every day, I can get 4 days use off of a simple charge. I guess over time this might reduce due to the battery degradation, but it's a modern cell and holds it's charge well.This is a very good unit, if you want to clean windows/showers and collect condensation I think you'll be pleased at this price.

Bought this to replace a Vileda that failed after long service.Though it works well, if not held at the correct angle it will leave streaks; considering that Bosch make windscreen wiper blades I don't think the rubber blades are the right shape at the scraping end.That said it works well on large areas like a shower screen and tiles. Narrow head great for frenchdoor glass.

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.

I am really delighted with the Bosch window Vacuum speed good love the design and power also DurabilityEase of removal .

Bought this to help clear condensation on my windows, easy to use and sucked up all the condensation with no problems. Also great when washing my windows and no streaks left. Would recommend.

The idea of the product was good - but the functionality was below my expectations.First and foremost, the vac was rather noisy - so not ideal if you have babies/people sleeping nearby.Secondly, the vacuum suction is a good idea but unless your windows/glass are at an easy angle to reach, I’d say a squagee with a microfire cloth are much more effective if you want a streak free look.I wanted to like it, but it was way below my expectations so it was returned.
