If you want portability, convenience, and quick cleanups of small spills or pet accidents, go with Shark StainForce. If you care more about powerful suction, deeper stain removal, and bigger jobs on carpet or upholstery, then Hoover CleanSlate Pro is probably the better choice.
Why this matters: many people pick a spot cleaner expecting both ease and power — but these two machines emphasize different strengths. Pick based on what kind of messes you deal with most.

Hoover CleanSlate vs Shark StainForce: Product Overviews
Shark StainForce
Shark StainForce is a cordless spot-cleaner designed for quick responses to spills, stains, or pet accidents. Because it’s battery-powered and compact, it’s ideal for small jobs — think stairs, car interiors, upholstery, rugs, or quick cleanups on the go.
Hoover CleanSlate Pro
Hoover CleanSlate Pro is a corded portable spot and upholstery cleaner engineered for more serious stain removal. With powerful suction, multiple tools (wide-path, tight-spot attachments), and a larger fluid capacity, it’s meant for carpets, larger stains, upholstery, and deeper clean-ups in homes.
Shark StainForce or Hoover CleanSlate: Key Dimensions
Design & Usability
- StainForce — cordless, lightweight, very easy to grab and use whenever a spill happens. Great for apartments, cars, stairs, couches — anywhere you want quick flexibility.
- CleanSlate Pro — corded and a bit bulkier, but still portable enough to move around the house. The added power and attachments come at the cost of needing a power outlet and a bit more effort to maneuver.
Cleaning Power & Performance
- StainForce — good for fresh stains, small spills, pet accidents, and quick spot cleaning. It’s convenient and fast, but suction and water-pickup are more modest compared with bigger machines.
- CleanSlate Pro — strong suction and extraction power. Reports and user tests show it handles tougher stains (coffee, wine, mud, pet messes) better, especially on carpets or upholstery — and typically leaves less moisture and deeper cleaning results.
Maintenance & Convenience
- StainForce — very low friction: no cords, quick setup, minimal storage space. Great for frequent light jobs.
- CleanSlate Pro — needs more setup (fill water & solution, plug in cord), and clean-up might take more time after heavy sessions — but performance is more powerful, and for bigger messes the tradeoff is worth it. The included hose-rinse tool makes maintenance simpler.

Hoover CleanSlate Pro Cons

🧩 Major Differences & When to Choose Each
- Speed vs Power — StainForce is about speed and convenience; CleanSlate Pro is about deep cleaning and power.
- Use-case matters — Spill on carpet from a cup or muddy paw prints on couch: StainForce works fine. Old stains on carpet, big messes, pet accidents on rugs, or deep sofa rugs: CleanSlate Pro handles it better.
- Home type & lifestyle — Small apartment, quick messes, occasional accidents → StainForce. Larger home with carpets, pets, regular stains → CleanSlate Pro.
- Frequency of use — Frequent quick cleanups → StainForce. Occasional deep cleanings or tackling big messes → CleanSlate Pro.
In short: StainForce = convenience + portability. CleanSlate Pro = suction + deep cleaning power.

Technically yes, but it’s best suited for small rugs or spot-cleaning. For deep carpet cleaning or larger areas, CleanSlate Pro will perform much better.

🔎 My Recommendation
If your priority is convenience and speed — especially for fresh spills, pet accidents, or quick cleanups in small spaces — go with Shark StainForce. It’s lightweight, fast, and perfect for everyday messes.
If you regularly tackle carpets, rugs, upholstery, or older stains, or want a machine that can deep clean more stubborn messes, Hoover CleanSlate Pro is worth the extra setup and bulk.
Bottom line: choose based on how and where you clean most often — not which sounds “better.”
