UWANT B300 Pro: The Portable Carpet Cleaner for Pet Stains & Everyday Spills

Let’s be honest: spills happen. Whether it’s your dog tracking mud across the brand‑new rug, your toddler’s juice cup taking a dive on the sofa, or that coffee you sloshed onto your car’s passenger seat — stains are inevitable. But dealing with them? That doesn’t have to be a nightmare.

I recently got my hands on the UWANT B300 Pro portable carpet cleaner (currently on sale for $79.99). After putting it through a week of real‑life torture tests — red wine, pet urine, greasy car seats, you name it — here’s my honest review.

Why I Needed a Portable Cleaner

I have a golden retriever named Milo. He’s adorable, but he’s also a mud‑magnet. My living room carpet is a light beige — a terrible choice, I know. After one too many scrubbing sessions that left me with sore knees and a still‑visible stain, I decided it was time for something more powerful than a paper towel and a prayer.

Traditional carpet cleaners are huge, heavy, and a pain to haul out for a single spot. Professional cleaning costs $100+ per visit. I needed something that lives in my closet, ready to go the second a spill happens. That’s where the B300 Pro comes in.

First Impressions & What’s in the Box

The B300 Pro is surprisingly compact — about the size of a small portable vacuum. It weighs only 8.38 lbs, so carrying it up stairs or out to the car is effortless. The build feels solid, and the bright accents give it a modern look.

In the box you get:

• Main unit with 9.84 ft power cord
• Fabric small brush head (with 2-in-1 brush plate)
• Self-cleaning tower assembly
• 500ml cleaning solution
• Lint cover assembly
• Detachable silicone brush plate (great for leather)

Real‑Life Stain Tests

🐾 Test #1: Old Pet Urine Stain (The Nightmare)

Milo had an accident last month that I thought was gone. But after a humid day, that unmistakable smell came back. I sprayed the B300 Pro’s cleaning solution, let it sit for 15 seconds, then scrubbed and extracted. The dirty water tank filled with brownish liquid — proof that my old “clean” carpet was still hiding nasties. After one pass, the stain was gone. After two, so was the smell.

🍷 Test #2: Red Wine on Light Beige Carpet

I deliberately poured a small amount of red wine (yes, on my own carpet — for science). The B300 Pro’s 18,000Pa suction pulled up almost all the wine in one go. A second pass with a little more solution erased any remaining pink tint. Within an hour, the carpet was dry and looked untouched.

🚗 Test #3: Greasy Food Stain on Car Seat

My car’s passenger seat had a mysterious dark spot from a takeout bag that leaked. The B300 Pro’s portable design meant I could easily bring it to the driveway. The silicone brush attachment worked perfectly on the faux leather. After extraction, the seat looked brand new — no greasy residue.

The Self-Clean Feature: A Game Changer

One thing I hate about carpet cleaners is cleaning the machine itself. The B300 Pro has a one‑touch self‑clean button. After you’re done, you press it, and the machine automatically flushes the hose and brush head. The dirty water goes into the tank, and you just empty it. No nasty surprises, no taking apart hoses. This alone makes it worth the price.
