How To Use B400 Carpet & Spot Cleaners?

Check out the video content on our support center

How to Switch Cleaning Modes?

This machine offers two cleaning modes: Hot Water Mode Press the "Water" button on the handle once. Preparation Time: 15-25 seconds for hot water. Steam Mode Quickly press the "Steam" button on the handle twice. Preparation Time: 30-35 seconds for steam. Note: During steam preparation, a small amount of water may discharge—this is normal. For optimal performance, wait until the mode is fully prepared before starting cleaning.

Why is the surface still damp after cleaning?

(1) When operating the machine, there's no need to hold down the water spray button continuously. Simply wet the stained area thoroughly, wait for the stain to dissolve, and then scrub. (2) The upholstery cleaner works similarly to a washing machine—cleaned items will naturally remain wet. First, spray water and scrub, then keep the brush head upright and press down to suction, much like blow-drying hair. The longer you suction, the drier the surface becomes.

How to Handle Machine Leakage?

(1) Clean Water Tank Leakage: Lift the water tank separately to check if it continues leaking. If leaking: Replace the tank. If not leaking: Normal operation. (2) Dirty Water Tank Leakage: Check if internal components are properly installed. If still leaking after correct installation: Replace the dirty water tank. (3) Machine Base Leakage: Check for foam overflow. If excessive cleaning solution prevents the float from rising: Empty the dirty water tank. Rinse residual cleaning solution from the clean water tank. Restart the machine and check for water stains at the base. If leakage persists: Internal component failure—contact after-sales service for repair. Note: Dilute cleaning solution at a 1:30 ratio. Over-concentration may cause overflow, affecting performance and cleaning results.

How to do if the machine stops work?

First, make sure the power connection is secure. Then, check for any blockages inside the machine. If everything looks fine, try resetting the machine. And if the issue persists, just reach out to our support team for further assistance.

What to do if the machine has no suction/suction weakens?

(1) Check if the dust-cleaning mechanism is jammed by debris or hair. If so, clean it thoroughly and manually slide the mechanism back and forth at least 3 times before reuse. (2) If the issue persists, the dustbin may be faulty - try replacing it. Note: Always empty the dustbin promptly when full during use to prevent clogging and maintain optimal performance. Excessive dirt accumulation may affect functionality.

Which Materials Are Suitable for Cleaning with an Upholstery Cleaner?

Generally, any material that is water-washable can be cleaned with an upholstery cleaner. Note: For delicate or expensive materials (such as wool carpets, leather sofas, or latex mattresses), it is recommended to test the cleaner on a small, hidden area first. If no issues occur, proceed with full-scale cleaning.

Does it come with a warranty?

Yes, B400 products have a 1+1 year warranty. If you have any problems in the use of the product, feel free to contact us.

What happens if I don't like it?

It can be returned free of charge within 30 days, please note: only products that have not been used will receive a full refund.

How fast is shipping?

We ship via UPS, usually 2-5 business days delivery.

Awesome Multi-Surface Cleaner!

This portable steam cleaner works amazing on carpets, sofas, and car seats. The hot water mode tackles fresh stains fast, while steam breaks down old grime without harsh chemicals. Its lightweight, easy to store, and dries surfaces quickly way better than bulky rental machines.

Great Product!

The UWANT B400 is a lifesaver for pet owners! The 212F steam mode eliminates pet odors completely, and the 18KPa suction pulls out deep stains I couldnt remove with other cleaners. The 2-in-1 water tank is so convenient, and the self-cleaning feature makes maintenance a breeze.

Michael Davis
Super Powerful & Effective!

Im impressed with the strong suction on the B400. It deep cleans high-traffic carpet areas and lifts embedded dirt effortlessly. The dual steam and hot water modes give professional-level results at home, and the attachments reach tight corners easily. Worth every penny!

Sarah Wilson
Easy to Use & Self-Cleans!

Super user-friendly right out of the box. The all-in-one tank design saves so much time, and the self-cleaning function keeps the machine fresh. It handles coffee, wine, and food stains perfectly, leaving no residue or wet carpet behind. Highly recommend!

Jessica Anderson
Better Than Big Name Brands!

I tested Bissell and Hoover before buying the B400, and this one performs better for less money. The steam sanitizes as it cleans, suction is stronger, and its more compact. Great for quick cleanups and deep cleans alike my new go-to cleaning tool.

No More Wet, Smelly Carpets—Dries Fast!

I hated old cleaners that left carpets soaking for days. This one extracts almost all water, so carpets dry in hours with no musty smell. It cleans deeply, wipes out all stains, and is super easy to maintain. I’ll never use another carpet cleaner again!

This Carpet Cleaner Saved My Pet-Stained Carpet!

I have two dogs that track in mud and have accidents sometimes, and my carpet was a total disaster. I tried sprays and scrubbing, nothing worked. This machine pulled out all the old stains and dirt I thought were permanent. Super easy to use—just fill, clean, empty. Dries fast too, no mildew smell. Worth every penny for pet parents!

So Easy to Use, Even for Cleaning Newbies

I’m terrible with gadgets, but this machine is idiot-proof. No confusing buttons or fancy setup. It cleans deeply without leaving sticky residue, and the fresh scent is great. I cleaned my whole house in an hour, and it dried in 3 hours. Perfect for busy people who want nice carpets!

Perfect for Small Apartments & Quick Cleans

I live in a 1-bed apartment with wall-to-wall carpet, and this cleaner is compact enough to store in my closet. It works great for spot cleans after messy meals and full-room deep cleans. The cord is long enough to reach every room, and the upholstery attachment works wonders on my couch. It’s gentle on carpet but tough on grime—my go-to cleaning tool!

Beats Professional Carpet Cleaning by a Mile

I paid for pro cleaning twice, and they didn’t get half the stains out. This machine did a better job for a tiny fraction of the cost. It cleans deep, dries fast, and I can use it anytime. No waiting for appointments, no heavy equipment to haul. Total home essential!

W
Williams
INCREDIBLE

I was skeptical because I’ve had bad carpet cleaners before, but this one blew me away. It glides smoothly across the floor, agitates dirt without damaging fibers, and sucks up so much dirty water it’s gross (in a good way!). My 10-year-old carpet looks brand new, and the pet smells are completely gone. No more musty, dingy carpets—this machine does it all.

M
Martinez
Restored My Old Carpet to Like-New

My 8-year-old carpet was dull, matted, and covered in stains. After one clean with this machine, it looks like I just installed new carpet! The brush roll fluffs fibers, suction removes embedded dirt, and no soapy film left behind. Gentle on carpet, tough on grime—so impressed.

Mom-Approved for Messy Kids & Pets

Between kids spilling snacks and dogs making messes, my carpet takes a beating. This cleaner is quick to assemble and use for spot or deep cleans. Durable, effective, and cuts down my scrubbing time so much. My house stays clean without the hassle—highly recommend to all parents!

It holds a good amount of water to get stuff done and I really liked how it doesn't over soak the fabric too much, perfect for using it on my car seats as well, good power I'm really happy with the quality of it

Compact and powerful cleaner

Very portable and efficient , the hose is easy to put away and the add on nozzles work really well. I wish the clean water and dirty water were in separate containers instead of combined into one. Overall it is powerful, compact, and looks good

Works great and is easy to use.

Works great and is easy to use. The spot in my pic it removed was from a rubber tire. So, while the cleaning solution appears to be designed for pet messes, it still works great for other things too. The auto-clean feature that is made for cleaning the wands themselves, works fairly well, but the large one also opens easily if you need any additional cleaning. Nice and light weight too.

Strong Suction And High Quality Build.

I purchased this to clean my carpet, and it exceeded my expectations! It’s incredibly effective and so easy to use. I even tried it on my car seats, and it worked perfectly. The suction is strong enough to get all of the dirty water out. I’m extremely satisfied with this product and would highly recommend it to others.

Sofa Deep cleaning

I used this uwant carpet cleaner on my couches and sofa, and it worked great. There were deep stains that had been there for a long time, and the steam with hot water really helped remove them. The suction is strong, and the upholstery tool makes it easy to clean furniture. The machine is portable and simple to set up, and the tanks are easy to fill and empty. After cleaning, my couches look fresh and almost new again.
