To find the best home carpet shampooer, consider weight and size, shampooer style, cords and attachments, and carpet damage. Buying a carpet shampooer is cheaper in the long-term than renting one for people with pets or young children.
The weight and size of the machine is an important consideration especially for tight hallways and spaces. Bulky and heavy equipment is difficult to use and maneuver. Special considerations for transportation also need to be made when renting a carpet shampooer.
Carpet shampooers with rotating brushes are effective for cleaning heavy soils, spreading the shampoo and grooming the carpet. These need to be used carefully, however, as they may damage carpet fibers depending on the type of carpet.
For thorough and easy cleaning, consider a shampooer with stair and upholstery attachments. The electric chord should also be long enough to reach out-of-the-way areas.
Lastly, the shampooer should be recommended for the specific type of carpet being cleaned. Apart from fiber damage, strong cleaning solutions can compromise the quality of the carpet. It's important to read the list of ingredients on the shampoo bottle before cleaning. It's also a good idea to test the cleaning solution on a small, hidden area before cleaning the entire carpet.
