Among various flooring choices, carpets and hard floors are the most common options. Carpeting accounts for half of all flooring sales. Carpets are relatively less expensive than other floor surfaces, and many people like the way carpet muffles sound and feels cozy on their feet especially in cold weather. Hard flooring is no doubt more expensive but it is known to be more hygienic, hypo-allergenic, and easier to clean. Carpet stains easily, and dirt can get trapped in the fibers, making carpet a poor choice for asthmatics.

Besides the health related benefits of hard floors, they are easy to clean and stay new for decades if they are cleaned and cared for properly. It is easy to spot any dust, crumbs, pet hairs, and dust particles, and spills are easily cleaned. To keep them shiny, hard floor surfaces should be mopped or scrubbed. Scrubbing and mopping the floor is a tedious task if done manually.

To make mopping hard surfaces easier, iRobot has introduced the Scooba line of robot cleaners that specialize in cleaning and scrubbing your floors killing bacteria. If you have toddlers, pets, or asthmatic people in your home then a Scooba robot is a healthy choice for your family. We have selected three of the top Scooba models by iRobot and will present you a review to highlight your best choice.
