The answer to 'carpet cleaning frequency' is that most experts recommend having your carpets professionally cleaned every 12 to 18 months. Regular vacuuming and spot cleaning can help maintain your carpets between professional cleanings, but deep cleaning by a professional is important to remove built-up dirt, dust, and allergens that regular cleaning can't reach.
The frequency of professional carpet cleaning can vary depending on factors like the amount of foot traffic, whether you have pets, and whether anyone in your home has allergies or asthma. Homes with higher traffic or pets may need cleaning more often, while homes with lower traffic and no pets may be able to go 18-24 months between cleanings.
