| Capacity | 0.6 gallons |
|---|---|
| Power Source | Electric |
| Included Components | 2-in-1 Pet Tool, 6 oz Solution, Accessory Hose, Nozzle Cleanout Tool |
The Hoover PowerDash Pet Advanced is a lightweight, compact upright carpet cleaner built to handle pet stains and everyday messes across carpets, stairs, and upholstery. It uses a PowerSpin Pet brush roll and included Paws & Claws sample solution to agitate and lift pet soils while suction extracts water; HeatForce technology speeds drying so you can use cleaned areas sooner. The unit is easy to carry and store, and the low-profile foot helps reach under furniture. Included attachments — a 2-in-1 pet tool and accessory hose — let you treat stairs and sofas without a separate machine.

For pet owners dealing with frequent accidents, its pet brush and formula give focused cleaning performance in a portable package.
Best for: Buyers who want a portable, pet-focused carpet cleaner for frequent spot cleaning and treating accidents around a home with dogs, and who value easy storage and quick drying.
Less Ideal for: Large households or users who need a heavy-duty deep cleaner for whole-house treatments should consider a full-size or commercial machine instead.

| Item Volume | 128 fluid ounces |
| Surface Recommendation | Carpet, Floor, Upholstery |
Rocco & Roxie Enzyme Stain & Odor Eliminator is a professional-strength, enzyme-based liquid designed to tackle organic pet messes on carpets, upholstery, hard floors and litter areas. You use it by blotting up excess material, applying the solution, letting the enzymes work, then blotting or agitating and allowing the area to dry; the formula is chlorine free and CRI certified safe for carpets. In practice it breaks down urine, feces and vomit residues rather than masking smells, which makes it useful for recurring odor problems and for stubborn soiling like dog diarrhea if solids are removed first. The product comes in a 128 fl oz bottle suited to multi-pet households and includes guidance to pre-test for colorfastness.

|---|---|
| Formulation | OXY-based carpet formula |
| Scent | Febreze Linen & Sky |
| Compatible use | For BISSELL upright and other leading deep carpet cleaners |
This formula is built for pet messes: it uses OXY chemistry to break down organic stains like urine, vomit, and mud while Febreze adds a light Linen & Sky scent. You use it in BISSELL upright machines and most other leading deep carpet cleaners by adding the recommended dose to the machine's clean water tank, then extracting the soil and solution as you clean carpets, area rugs, stairs, and upholstery.

Choosing the Right Carpet Cleaner for Dog Diarrhea: Key Factors to Consider
Extraction Power
High extraction capacity matters because it forces more water and contaminated solution out of carpet fibers, reducing staining and shortening drying time. Machines with stronger suction and efficient recovery tanks leave carpets less damp, which lowers the chance of odors redeveloping and limits bacterial growth.
When evaluating extraction, consider motor airflow and water lift ratings if available, but also look for user-focused design elements such as independent pump systems and clear recovery-tank level indicators. For pet messes, stronger extraction is often more valuable than larger clean water capacity because it shortens the number of passes needed and speeds cleanup.
Odor Neutralization and Sanitizing
Removing visible soiling is only part of the job. Dog diarrhea can leave odor-causing compounds and bacteria deep in fibers. Machines that are compatible with enzyme-based cleaners or have built-in sanitizing rinse options help break down organic residues and neutralize smells rather than masking them.
Check for compatibility with proven pet-safe enzymatic cleaners and features such as hot-water capabilities or rinse cycles designed to dilute and remove residues. Also consider whether the unit materials tolerate those cleaning agents without degrading seals or hoses over time.
Brush Design and Agitation
Effective mechanical agitation helps lift semi-solid or dried fecal matter from fibers so the extraction system can remove it. Nylon or mixed-fiber brushes, counter-rotating brushes, or adjustable-brush-height settings improve contact with carpet pile and make cleaning faster and more thorough.
Look for brush systems that are removable for cleaning and that do not trap debris inside the brush housing. Gentle but effective agitation reduces the need for repeated scrubbing, which can wear carpet fibers and spread contaminants if done improperly.
Tank Access and Maintenance
Cleaning up after pet waste requires sanitary, easy-to-empty recovery tanks and accessible internal parts. A clumsy tank that splashes during emptying or is difficult to rinse increases the chance of contamination and makes routine use unpleasant. Clear markings for water levels and a wide-mouth recovery tank simplify disposal and rinsing.
Durable seals and parts that resist staining and odor retention are important. Removable filters and serviceable hoses reduce the chance that trapped waste causes lingering smells between uses.
Tools, Hose Reach, and Versatility
Pet messes rarely occur only on open carpet areas. Stairs, upholstery, and vehicle interiors are common trouble spots. Units with a long hose, wand, and dedicated upholstery or stair tools let you clean these areas without awkward positioning. A hand tool with strong suction and a built-in brush makes spot work more effective.
Consider the length and flexibility of the hose, the weight of the wand for hand-held work, and whether attachment storage is convenient. Versatile tooling reduces the need for multiple devices and speeds targeted cleanups.
Drying Time and Residue
Faster drying times reduce the risk of re-soiling and bacterial regrowth after a pet accident. Machines that remove more moisture and allow for a rinse-only pass will leave carpets closer to normal in hours rather than days. Low-residue cleaning systems that rinse out soaps and enzyme cleaners effectively are preferable for odor control.
Also consider whether the machine supports a final cold-water rinse cycle to remove cleaning-solution residue. Residual detergents can attract dirt and prolong smell issues if not fully extracted.
Preparing the Area Before Cleaning
Start by removing any solid material with a disposable tool and wearing gloves. Blot fresh moisture gently with absorbent cloths to remove excess without pushing it deeper into the fibers. Protect yourself and any household members by limiting access to the affected area until cleaning is complete.
If the mess has soaked through to a carpet pad, lift the carpet edge if possible to check saturation. Heavily soaked padding may require targeted treatment or replacement to avoid long-term odor problems.
- Remove solids with a disposable scoop or paper towels.
- Blot—do not scrub—fresh moisture before machine cleaning.
- Check carpet backing and padding for saturation.
Safe Cleaning Solutions and Enzymes
Enzyme-based cleaners break down organic matter and odors at a molecular level and are often the best chemical approach for pet waste. Use products labeled safe for pets once properly rinsed from the surface. Avoid high-alkaline or bleach-based solutions that can damage carpet fibers and irritate pets.
Follow manufacturer guidance on dilution ratios for any cleaning solution used in a carpet cleaner. Over-concentrated solutions leave residues that trap soils and retain odors, while under-diluted solutions may not effectively neutralize bacteria and odors.
- Choose pet-safe enzymatic products compatible with hot-water extraction.
- Dilute cleaning solutions per the instructions to avoid residue.
- Perform a spot test on an inconspicuous area before full cleaning.
Dealing with Stubborn Stains and Repeat Messes
For set-in stains, allow an enzyme solution to dwell according to product directions before using the carpet cleaner. Multiple short passes with strong extraction often work better than prolonged single passes. If residue remains after cleaning, repeat the rinse cycle with plain water to remove cleaning agents that can attract dirt.
For households with repeated incidents, establish a quick-response kit that includes disposable tools, enzyme spray, absorbent pads, and access to the cleaner and hand tool. Quick response reduces staining and long-term odor retention.
- Allow dwell time for enzyme cleaners on set-in soils.
- Use multiple short extraction passes rather than extended single passes.
- Rinse with plain water after cleaning to remove detergent residues.
Maintenance to Prevent Odor Build-Up
Regularly rinse and dry tanks and hoses after pet-related cleanups to prevent bacterial growth and lingering smells. Leave recovery tanks open to air dry when not in use and occasionally flush hoses with a mild disinfecting rinse compatible with the machine's materials.
Replace worn brushes, seals, and filters per the manufacturer's guidance. Neglected parts can trap waste and become the source of persistent odors that a high-performance cleaner cannot overcome.
- Empty and rinse tanks immediately after use.
- Air-dry parts and periodically sanitize hoses and brushes.
- Inspect seals and filters and replace when worn.
When to Call a Professional
If carpet padding is saturated or odors persist after multiple professional-strength extraction attempts, professional restoration may be necessary. Technicians can assess pad replacement, deep sanitizing, and deodorizing techniques that are beyond consumer-grade equipment.
Consider professional help when stains are widespread, or the affected area includes sensitive textiles or antiques where improper cleaning can cause damage.
- Seek pros for saturated padding or persistent odors.
- Use professionals for delicate or valuable textiles.
- Document treated areas and methods before scheduling a service.
How We Chose the Best Carpet Cleaner for Dog Diarrhea
We selected machines that address the specific demands of cleaning dog diarrhea from carpets and rugs. Our evaluation emphasized measurable cleaning performance, including water extraction efficiency and agitation or brush design that dislodges dried or semi-solid soils. Odor control and sanitizing capability were prioritized to ensure bacterial and odor-causing residues are reduced, not just masked. We also weighed practical maintenance factors such as tank access, filter protection, and how easy the recovery tank is to empty and rinse after pet waste cleaning. Durability and materials were considered so the machines stand up to repeated deep-clean cycles and exposure to enzyme or disinfecting solutions. Hose length, reach, and included upholstery tools were noted for real-world cleanups in tight spots like stairs and furniture. Noise level and drying time were included because quicker dry times reduce the risk of re-soiling and lingering smells. We excluded machines intended only for light spot-cleaning or for hard floors, and we did not consider tools that lack sufficient extraction power or have impractical maintenance for pet-related cleanups.
Our full evaluation process is outlined in our review methodology.
FAQ
Can a carpet cleaner completely remove the smell of dog diarrhea?
Often a carpet cleaner combined with enzyme-based cleaners will significantly reduce or remove odors. Success depends on how quickly you clean, whether the padding is contaminated, and whether you rinse out cleaning residues that can trap smells.
Is it safe to use enzyme cleaners in a hot-water extractor?
Usually yes, but check compatibility with your machine's materials and the enzyme product instructions. Enzymes are designed to break down organic matter and are effective when allowed to dwell before extraction.
How soon should I clean a fresh accident on carpet?
Clean as soon as possible. Blot excess moisture, apply an appropriate enzyme solution if available, then follow with extraction. Faster response reduces staining and the likelihood that odors will set.
Will repeated use of a carpet cleaner damage my carpet?
Not if you use the proper settings, avoid over-wetting, and rinse out detergents. Overly aggressive brushing or excessive moisture can stress fibers and backing, so use recommended agitation and extraction techniques for pet messes.
How do I tell if the carpet pad needs replacement?
If odors persist after thorough cleaning and the pad feels soggy or is discolored, the padding may be contaminated. Replacing the pad is often necessary to eliminate deep-seated odors.
Final Verdict
Prioritize machines with strong extraction, compatible enzyme cleaning support, and easy-to-maintain tanks and tools when choosing a carpet cleaner for dog diarrhea. Brush design and appropriate tooling matter for stairs and upholstery, while short drying times and thorough rinsing reduce the chance of lingering odors. Balance extraction power with a unit you can maintain easily to ensure reliable, sanitary cleanups over time.
