Mint Plus (upper left) is the latest in Mint's lineup of hard-floor cleaners that use Swiffer or other disposable cleaning cloths to dry-sweep (a maximum run time of 4 hours/1000 square feet) or a reusable microfiber cloth to wet-mop (a maximum run time 2.5 hours/350 square feet).

Designed for pet owners and allergy sufferers, the Neato XV-21 (bottom left) promises the most powerful suction of any robotic vacuum cleaner and offers a specially designed filter that retains more than three times the amount of fine dust particles compared with standard filters. It also uses a laser map to clean the room efficiently, using a straight-line back-and-forth pattern.
Neato XV-21 | Releasing in May; available for preorder on Amazon.com | $429
The iRobot Scooba 230 Floor Washing Robot (right) is great for germophobes because its small size allows it to clean in tight spaces (such as around and behind toilets); the maker says it can kill 97 percent of germs and bacteria, too. Even though it can also clean under cabinets, some users recommend using a larger Scooba in the kitchen.
