Maintaining a clean carpet can be a challenge for everyone, but for pet owners, it requires a good vacuum for pet hair, specialized tools for removing pet hair, and frequent cleaning of pet urine and feces stains, as well as eliminating pet odors. Despite these efforts, accidents and messes will occur, so it’s essential to have the right carpet cleaner for pet stains and odors on hand. One of the most challenging to remove is pet urine, as it can cause discoloration of carpet fibers due to the ammonia content. Peters states, “The longer urine stays on the carpet, the more likely it will cause a permanent color change.” This highlights the importance of cleaning up urine stains promptly. Additionally, urine can penetrate deep into the carpet padding, which is why odors, particularly from cat urine, can persist Pet stains can include urine, feces, and vomit, each with their own unique challenges. Urine can cause discoloration in carpet fibers due to its ammonia content, and should be cleaned up quickly to prevent permanent damage. Feces can be difficult to clean due to the proteins and bacteria it contains, and vomit can be even more challenging because of its acidic nature. Other common sources of stains include muddy paws, dirt, grass, and pollen. To keep carpets clean, it is recommended to use specialized products such as pet stain removers and UV urine detection flashlights in conjunction with a pet carpet cleaner.According to Guy Peters, owner and founder of MOP STARS Cleaning Service, his top choice for the best carpet cleaner for pets is the Bissell SpotClean Pet Pro.

It weighs only 13 pounds, making it portable and easy to use around the house, and comes with two tools and a bottle of Pet Pro Oxy Urine Eliminator formula.

This means less time spent refilling the tank, and it can also be used for non-pet-related cleaning tasks like baseboards.
