Is it best to use hot or cold water?

I’ve had a Karcher window vac for over 5yrs, they’re excellent! Always used a bucket and sponge with hot water and Flash solution. Bought the spray bottle and Karcher solution very recently. The spray bottle is more convenient to use, but the Karcher solution is rubbish compared with using Flash! I always use hot water - you wouldn’t wash your dishes in cold water and Fairy Liquid would you? Hot is better for dissolving grease and grime such as grandkids sticky finger marks on patio doors!

Does the spray bottle come with fluid / sachet to make up the fluid like the old one, or do you have to purchase this separately ?

Just a sample sachet, but it's enough to do a six sided conservatory, the bottle of cleaner I bought with it will last a very long time!

Does this leak. My original one that came with the karcher soaks me.

Mine too can anyone advise can you buy new seals/washer

How narrow does this go down to and isn't it easier to use a cloth and bucket then a archer vac for Georgian panes?

There are two different sizes of sponge thing and two different sizes of wiper blade. Should be ok. Not good for contoured glass though.
