Automatic pool cleaning machines have grown in popularity as manufacturers develop innovative machines that clean pools with little human involvement. While automatic cleaners are more expensive initially than suction-side and pressure-side cleaners, they provide benefits like immaculately clean pools within a few years that save owners time and money in the long run. Above ground winter pool covers are made of strong, durable materials like woven polyethylene that withstand harsh weather to prevent pool damage during winter months. They have laminated inner layers and weather-resistant coatings to protect pools from sunlight and weather each year.
