If you're tired of pushing a heavy vacuum around just to keep up with daily messes, check out the Huije Auto Self Charging Robot Vacuum Cleaner. With 2000Pa of suction, this little machine is no slouch when it comes to tackling pet hair and dirt on your hardwood floors. What I really appreciate is the tangle-free technology; it won't get jammed up with pet hair like some other models I've tried. It's got a variety of cleaning modes, so you can customize it to fit your needs. And you won't have to worry about it dying mid-clean—the battery lasts up to two hours, and it heads back to its charging base when it gets low. No Wi-Fi or apps to mess with, either—just press the button and let it do its thing. Maintenance is pretty straightforward, too. All in all, a pretty handy little robot to have around the house.
