But it!

I’ve had 3 robot mops over the years and this one is finally the one that feels worth the money. The iRobot Roomba 420 plus AutoWash Dock cleans the floors great, but the best part is how little I have to mess with it. No hand washing nasty mop pads. No constantly refilling the water tank every five minutes. And it actually dries the mop pads when it’s done — which keeps that sour mop smell away. Huge win. The dock does most of the dirty work for you, and honestly that’s what makes this model stand out from my older Roombas. If you’ve got a husband who goes in out, grandkids, pool traffic daily or a busy house, it’s a game changer. I’m picky about floors looking clean, especially with light floors, and this thing has impressed me. Technology finally caught up with lazy cleaning… and I’m here for it. 😂

Worth the investment

Love this Roomba! I’ve had a vacuum/mop combo before, but it had the pad that drags, and it didn’t clean my textured wood floors very well. The spinning mops get deep into the crevices and do a great job. Love the fact that it cleans itself between jobs! I got it on sale, that being said it was worth every penny!
