The Uwant Portable Carpet & Upholstery Cleaner (B300‑style 18KPa spot cleaner) is a compact, 18,000 Pa suction handheld deep‑clean machine designed for carpets, sofas, pet beds, rugs, car interiors, and mattresses. It combines hot‑water extraction, spray, scrub, and powerful suction in one portable unit with a 2‑in‑1 water tank (41 oz clean water + 41 oz waste water), multiple brush heads, and a pet‑specific “Pet Pro” cleaning solution.

Marketed as a “not just a carpet cleaner” spot‑treatment system, this Uwant model is particularly popular with pet owners who need on‑demand stain and odor removal around the house and in the car.

What It’s For

This cleaner is ideal for:

• Carpets, rugs, and upholstery:

  • Removing food stains, drink spills, mud, and pet messes.

• Pet‑related cleaning:

  • Pet accidents, fur, dander, and odors on carpets, pet beds, and car seats.

• Cars and vehicles:

  • Interior spot‑cleaning seats, floor mats, and trim.

• Mattresses and couches:

  • Deep‑cleaning textile surfaces where stains and odors get trapped.

It’s not meant to replace a full‑sized upright carpet cleaner but to extend cleaning between deep‑cleaning sessions and handle fresh spots immediately.

Key Features

1. 18KPa High‑Power Suction

• 18,000 Pa suction:

  • Removes embedded dirt, spills, and pet stains more effectively than many 12–15KPa spot cleaners.

  • Compared to Uwant’s 12KPa‑style cleaners, the 18KPa version reportedly improves cleaning efficiency by about 50% and helps dry carpets faster with less lingering moisture or smell.

This strong suction means:

• Less re‑wetting and faster drying.

• Better deep‑cleaning on Berber, loop, and plush carpets.

2. Pet Pro Cleaning Solution

• Self‑developed “Pet Pro” solution:

  • Designed specifically for pet stains, dander, and odors.

  • Uwant claims up to 60% better cleaning efficiency over standard household cleaners on pet‑related messes.

• Comes with a spray bottle:

  • You can pre‑spray heavily soiled areas before passing the cleaner over them.

This makes it:

• Highly attractive to dog / cat owners.

• Effective for accidents, muddy paws, and odor hotspots.

3. 2‑in‑1 Water Tank (41 oz)

• Dual‑tank design:

  • 41 oz clean‑water tank.

  • 41 oz waste‑water tank.

  • Both tanks can be emptied and filled simultaneously with one hand.

Benefits:

• Fewer refills for quick spot‑cleaning.

• Less hassle than switching or cleaning separate tanks.

4. Spray, Scrub, and Suction (4‑in‑1 Concept)

The machine is designed for four actions in one:

• Spray:

  • Hot or warm water + cleaning solution misted onto the stain.

• Scrub:

  • Combined with the brush head, loosens embedded dirt.

• Suction:

  • Powerfully pulls water, dirt, and pet residue back into the waste tank.

• Self‑cleaning mode:

  • Uses a self‑clean brush head to rinse the internal hose and brush, reducing mold and odor buildup.

This “all‑in‑one” design:

• Cuts down time for spot‑treatment.

• Encourages immediate cleaning instead of letting stains sit.

5. Multiple Brush Heads & Attachments

Included accessories typically include:

• High‑density brush head:

  • For deep scrubbing carpets and textured rugs.

• Silicone brush:

  • Gentler on delicate upholstery and leather‑like surfaces.

• Velvet / soft brush:

  • For sofas, cushions, and fabrics that might snag.

• Self‑cleaning brush head:

  • Fits the machine to flush out the hose after use, keeping it clean.

This brush‑head versatility lets you:

• Adjust intensity from gentle wiping to hard scrubbing.

• Use the same unit for rugs, couches, car seats, and pet beds.

6. Compact, Portable, and Easy to Store

• Size:

  • 10 × 5 × 5 inches, about 5 lb (2.3 kg), which fits in:

    • Kitchen cabinets, closets, under‑sink storage, or sideboard shelves.

• Corded design:

  • Powered via a standard outlet, with enough cord length for flexible use around the house.

Users report that:

• The compact form makes it easy to grab quickly when a pet mess or spill happens.

Pros and Cons

Pros

• Very strong 18KPa suction for a spot cleaner
  Outperforms many 12–15KPa units on Berber, looped, and plush carpets.

• Pet‑specific “Pet Pro” solution
  Great for odors, dander, and accidents—ideal for pet‑owning homes.

• 2‑in‑1 dual 41‑oz tanks
  Convenient, one‑hand refilling and emptying.

Cons

• Corded only (no cordless option)
  You must stay near an outlet during use.

• Still small for whole‑carpet cleaning
  Best for spots, edges, and small areas, not full‑home deep‑cleaning.

• Some users report “plastic smell” when new
  Occasional report of new‑plastic odor, which typically fades after a few uses.

Real‑World Use

User reviews and demos of similar Uwant B300 / 18KPa models show:

• Excellent spot‑treatment for pet stains:

  • Removes fresh accidents and some older set‑in marks, especially with the Pet Pro solution.

• Good car‑interior cleaning:

  • Effectively cleans seats, floor mats, and trim without heavy‑machine hassle.

• Faster drying vs weaker suction units:

  • Thanks to 18KPa suction and higher extraction, carpets feel drier and less musty after a few passes.

Many reviewers praise:

• The handheld, go‑anywhere form, comparing it favorably with plug‑and‑play stain‑removal gadgets.

Who Should Buy It?

This is best for:

• Pet owners who deal with accidents, fur, and odors.

• Car owners wanting to keep interiors clean without hauling a big machine.

• People with small to medium‑sized carpeted areas, who want spot‑cleaning between professional or rental‑machine sessions.

• Renters or small‑apartment dwellers needing a compact deep‑cleaner that won’t dominate storage.

Less ideal for:

• Those who want to deep‑clean whole‑house carpets in one go; a full‑size upright or truck‑mounted cleaner is better for that.
