Spot cleaners are small, portable cleaning devices designed to tackle specific stains and messes on carpets, upholstery, and other surfaces. They typically use a combination of water, cleaning solution, and suction to remove dirt and stains effectively. Spot cleaners are ideal for quick clean-ups of spills, pet accidents, or other localized dirt without the need for a full-sized carpet cleaner. These machines often come with various attachments to target different types of stains and fabrics. Many spot cleaners are lightweight and easy to maneuver, making them convenient for home use. Popular brands include Bissell and Hoover, which offer a range of models to suit different cleaning needs.
