Been struggling hard with condensation this winter, was using a squeegee but i just cannot keep up (older house with Wooden frames) and just too much water.
I looked into Window cleaners and started with the Kmart one - Don't even waste your $35.
Did some brief research and found this, this seems to be a pretty good deal. You can get the WV6 Plus standalone for ~$169 shipped but that won't come with an Australian cable/plug (plus the time from the UK).
The only other aspect is if you need Horizontal cleaning as per here which additionally has a 200ml tank.avaliable as an order-in at Bunnings for $199.
Only issue is that shipping seems to be slower then expected for me (yet to arrive).
It’s one review is enough for me not to buy one.
