KW4070 Portable Carpet Cleaner

I was skeptical about it because of the small diameter hose and I always liked the big green machine.It works as good as the rental!I used this machine on all different carpet types and it worked perfect.It’s also quieter than the rental.It’s the same as using an upright vacuum.It extracted almost all the water I added.The carpet in the picture is over 50 years old; was a bit dull and had no stains. The shampooer cleaned it beautifully.My fill was between the small and large line.It’s user friendly, lightweight, and easy to store.I have been cleaning for over 50 years; had my own cleaning business and have shampooed a lot of carpets over the years.This unit works perfectly for residential use.It’s not a rugged unit, but it’s well made.If you treat it carefully and clean it after each use, I’m sure it will last.I have no complaints at this time.

I'd give this machine 10 stars if it were possible!! Of the 3 different carpet washers, this one is the best!I owned a Dirt Devil carpet cleaner. It did a better than the water system attachments for my Rainbow Cleaner. The suction was better, but it required additional upper body effort to extract the solution. The wet system for my Rainbow was very narrow and didn't have wheels on it and required even more upper body effort. My shoulder would hurt for days after I was done.The Kenmore KW4070 is amazing. I counted out the 9 capfuls of cleaning solution into a measuring cup. It comes up to 1/3 Cup. That saves you time when you go filling the clean solution container.The machine is so easy to set up and disassemble for clean-up. I love that the lid that covers the rollers comes out completely, so you can clean it well. My Dirt Devil and Rainbow wash system didn't do that. It always looked gross.I still use my Rainbow cleaner for vacuuming. I love the water canister that never loses suction. I also get great satisfaction on seeing what it really does through the see-through cannister. I vacuumed all the carpet really well with the Rainbow before washing. That water alone was horrendous!!! I worked on the perimeter carpet next to the molding using the 6" attachment. It worked a charm! After doing the perimeters, then I washed the carpet. I was in disbelief how filthy the carpet was. Whenever I've washed carpet my whole life, I've always gone back over it with a clear-water rinse. So, each of the rooms were done twice. I don't want soap dried in carpet. I believe the residue draws more dust and dirt in the future.The 'rinse water' was a lighter dirt color with additional foam.The extractor is so efficient that the carpet was dry in about 3.5 hours...max!I still have 2 rooms, 5 dining room chairs, 2 recliners, the basement, and the basement stairs to do.This machine has more than paid for itself already. If you tally the entire job, it would have cost me well over $700. The professionals charge around $15.00 per stair...alone.There is one concession. I wish the dirty water tank held more fluid.I look forward to my first vaccuming with the Rainbow to see the complete analysis. The carpet you see is 28 years old! It may not look great, but it is in very good condition. This is the best it's going to get. No shoes allowed rule over the entire time. It's my mom's condo. I can't replace it yet.UPDATE 1/21/2025: i finished all the jobs previously mentioned except for the stairs and basement. The machine has already paid for itself. I Googled the going rate for professional carpet cleaners. It would cost me over $700 just for the upstairs cleaning. They charge per square foot.The pictures I posted are the ivory carpet throughout the condo. This carpet was put down in 1996 when my dad had the place built. The 2nd picture of the variegated taupes is the breakfast nook. I took the picture so you could see a before/after comparison. That carpet is 3 years old. As you can see the difference in the portion at the bottom after cleaning, with the top still needing to be done. The machine restored the carpet to what it looked like when it was placed November 2021.

Wowza. I never really write reviews but this is a must buy!! I’ve had a Hoover and bissel carpet cleaner but this ACTUALLY cleaned my rugs. Joys of having munchkins and dogs! I bought zep carpet cleaner the cleaner that comes with it is not great but seriously love it. And it’s not bulky and complex. My home smells great.

Ok, works and doesn’t leak, but compared to my Hoover one in the past, I ran out of water/cleaning solution way too quickly and it took a lot of water only passes to finally get it from making stuffs when passing over that same area. But it was easier to clean the dirty water basin than the Hoover one I had and this one is easy to clean debris from the rollers (my carpet is like new shedding carpet in areas and other areas it’s shedding because it needs replaced, but it’s clean!!)

I've only used it once, so I'll update my review if anything changes, but it did an amazing job cleaning my living room carpet. The dirt it pulled out was disgusting and I probably need to clean a few more times soon to really get everything (even professional machines often need a few passes), but I'm really happy I made the purchase. I had been using the Bissell little green which is fine for small jobs, but this cleaned the whole carpet (2 separate passes) in about 20 minutes (I did really slow passes until I couldn't see any water being suctioned up) rather than an hour or more just for one pass and it pulled a lot more debris and just dirt out of the carpet, along with a much greater quantity of the water, so the carpet dried more quickly, too. The machine was easy to clean up and I was able to open up or pull out and rinse everything easily, not leaving visible dirt and debris behind in the machine. I also liked the cleaning fluid (a first for me; I've been on the hunt for years). It did a good job and didn't leave a noticeable smell behind- I'm really sensitive to smells. I didn't test out the attachments, but will update my review if I have any issues. The clean water tank didn't last very long (1.5 passes of my 8'x12' rug) so if you're doing your entire house refills might get annoying, but the dirty water tank lasted longer.

I grabbed this cleaner mostly for pet messes and it’s been solid. It’s light, easy to carry around, and doesn’t make a huge fuss. Just fill it up, hit the button, and it pulls up way more dirt than I expected. My rugs look way better now, and it doesn’t leave everything soaking wet. The tanks are simple to deal with, and the hose is handy for stairs and furniture. Not fancy, but it works—and that’s all I needed.
