Window Vacs for condensation

[bellbird]

Thanks everyone. My flat has underfloor and ceiling insulation, kitchen and bathroom extractor fans, venetian blinds and curtains, I crack open windows in the morning for a bit unless it's super cold. Windows are wooden framed and single glazed. Condensation is the same in unheated or heated rooms and will run down the walls if I don't use rolled up towels. Flat is concrete block no eaves. I put bubble wrap on the bigger (non opening) window in the spare bedroom during winter. I might get the Karcher WV1 Plus from Mitre 10 $89. No specs for that model on their website so I had to do a search. I found this website helpful https://spotlessvacuum.co.uk/window-vac/karcher/ for general info about the vacs.
