Bought this. Tried it with windows with condensation in the morning. The suction is so poor it just acts like a squeegee and piles up the water to run down onto the window sill. I was unfortunately reminded that Ryobi’s One+ handheld vacuum from years ago had equally poor suction but was hoping for better from this. Very disappointed as many other One+ tools are excellent.

Just Bought one of these and cleaning widows is no longer a chore that you will hate.
I already have alot of ryobi one + tools so I thought why not, its best thing ever and I also done the shower screen.
