Keeping your home fresh and hygienic means paying special attention to where pets spend their time. The Bissell Pet Pro is a popular choice for tackling this challenge, lifting stubborn stains and eliminating odors from carpets and upholstery. However, to ensure it continues to perform at its peak, a regular and thorough cleaning routine is essential. This guide will walk you through the complete process of cleaning your Bissell Carpet Cleaner Pet Pro, helping you maintain its efficiency and longevity.

Why Regular Cleaning of Your Pet Pro is Crucial

Over time, the very substances designed to clean—pet hair, dander, and organic spills—can build up within the machine. If left unchecked, this residue can clog the water tanks, block the spray mechanism, and even foster bacterial growth, leading to unpleasant odors being redeposited onto your clean floors. A clogged system also strains the motor, potentially shortening the lifespan of your valuable tool. By committing to a simple maintenance schedule, you protect your investment and ensure it remains ready for the next mess.
Preparing for the Cleaning Process

Before you begin, gather your supplies to make the process smooth and efficient. You will need warm water, mild dish soap, a soft cloth or sponge, a small brush or toothbrush, a clean towel, and a vacuum cleaner. It is also wise to consult your user manual for model-specific guidance, as procedures can vary slightly between the Bissell Pet Pro and other Pet Pro Express models. Always ensure the cleaner is unplugged and completely cool before you start any maintenance task.
Step-by-Step Exterior and Tank Cleaning

The exterior of the machine collects dust and the occasional paw print, while the internal tanks are the heart of the cleaning operation. Start by wiping down the outer shell with a damp cloth and mild soap to remove surface grime. For the tanks, you must first empty any remaining solution. Then, disassemble the solution tank and the clean water tank. Wash both parts thoroughly with warm, soapy water, using a soft brush to reach into corners and along the edges. Rinse them exceptionally well to ensure no soap residue remains, as this can affect the performance of the next load.
Deep Cleaning the Recovery Tank and Filter
The recovery tank, where dirty water is collected, requires special attention because it handles the heaviest debris. Pour out the dirty water and rinse the tank vigorously. Use a cloth or sponge to wipe the interior walls, removing any dried-on mud or hair. Next, locate the filter, which is often found in the clean water tank or within the recovery tank itself. The filter is a critical component that prevents debris from re-entering the carpet. Remove it and rinse it under running water until the water runs clear. Never use soap on the filter, as the residues will damage its structure. Allow it to air dry completely before reinserting it, as a damp filter can promote mold.

Maintaining the Brush Roll and Clearing Jams
Hair and stringy debris frequently wrap around the brush roll, preventing it from agitating the carpet effectively. To fix this, turn the cleaner off and unplug it. Locate the brush roll, usually at the bottom of the machine. Use scissors or a seam ripper to carefully cut away any hair tangled around the axles and bristles. While you have the roll exposed, check the intake area for any small objects like coins or paper clips that might have been vacuumed up. Clearing these obstructions ensures the brush roll can spin freely, maximizing the machine’s cleaning power on your floors.
Final Reassembly and Testing

Once all components are clean and dry, it is time to put everything back together. Carefully reinsert the dry filter into its housing. Place the clean water tank and recovery tank back into their respective slots, ensuring they are seated properly to avoid leaks. Replace the brush roll and securely fasten the side plates. To confirm that the machine is functioning correctly, perform a test run. Fill the tanks with clean water only, run the machine on a hidden section of carpet or a hard floor, and verify that the suction and spray action are operating smoothly without any unusual noises.
Establishing a Routine Maintenance Schedule

Consistency is the key to preventing major buildup and avoiding frustrating breakdowns. After every use, take a moment to empty the recovery tank and rinse the clean water tank if possible. A quick wipe-down of any spills on the exterior prevents dirt from hardening. Perform the full deep clean, including the filter, brush roll, and tanks, approximately once a month if the machine is used frequently, or at least once every few months for lighter use. By integrating these steps into your household routine, you ensure that your Bissell Carpet Cleaner Pet Pro remains a reliable and effective partner in maintaining a clean home.
