Pays for itself - save time, energy and mental health lol. I have a toddler that's of course always playing on our hardwood floor. Previously, I went with the "cheaper" option of sweeping with a broom then follow up with swifter mop. But this took 20 minutes or so and felt like a lot of work. The Crosswave reduced this to 5 minutes and I still have my energy to do other things. It makes cleaning the floor (and sanitizing) so easy. Now can quickly shine the floor without having to think "do I really want to"? I love shining my floor now because it's relaxing to do so with the Crosswave x7! The best part is it's cordless!!!
