Suitable for use on carpeted surfaces only when equipped with Microfibre (MF) rollers. The standard blue brushes that come with the unit are not recommended for carpet, as they create excessive friction that can cause the motor protector to engage, reducing performance and RPMs to prevent overheating. Can be paired with the optional Infinity X Pack, which allows operators to carry additional solution and recovery tanks. Features: Electronic board, water pump, suctions motor, drive motor and gears, and hose.
