KW4070 Carpet Cleaner

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.

Update nearly a year later: It's still working great. I've used it about once a month for the past year and my only issue is the smell of the cleaner that came with it. It isn't as strong as some, but my air purifier recognizes the air as contaminated for about 30 minutes after (the only other thing that makes it do that is burning something in the kitchen) so I usually clean just before going upstairs. 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 received this late Friday and used it for the first time on Sunday. It would not be possible for me to be happier! Previously I have rented machines and once employed a professional service to clean the carpet. This Kenmore machine did a better job of cleaning the carpet than either the rental or the professional! There were light stains in the carpet (not too noticeable but to me) which I thought would never come out. They're gone! No longer visible at all! I had vacuumed extremely well before using it but was shocked at just how much dirt this machine pulled from deep in the carpet. It was kind of disgusting, actually. I thought I was cleaner than that. The machine is lightweight and easy to handle. Read the instructions. It does not require a lot of cleaning solution. Much less than a rental does. It extracted nearly all the fluid from the carpet. I cleaned the carpet Sunday evening. Today is Monday morning and the carpet is dry in spite of high humidity. It may be a high investment for many people but if you have carpets it is worth it for the money you will save on rentals or outside services over time. No trips to lug heavy machines or allow strangers in your home. No time limits or being subject to waiting for someone who shows up late. You can clean small spots any time you like. For cleaning solution I used Zep general purpose carpet cleaning concentrate. I got a gallon and used a bit more than the 5 oz per gallon dilution. This gallon will last a LONG time for me.

A highly effective piece of equipment, easy to use, the motor is fairly durable, water capacity is pretty good, suction is great, its a pretty good value purchase. My biggest complaint is that the water tank cracked and now water pours out of it every time I fill it. I wouldnt be surprised if Kenmore would be willing to replace the tank however.

This steamer is easy to use, lightweight and does a nice job cleaning carpets. I’d recommend this one if you’re not wanting a bulky carpet cleaning machine.

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 purchased this unit after the 2 units I had recently took a dive (one was a Hoover that was 8 or so years old, other a Bissell just over 1 year old - motor died). After the issues with those 2 brands I decided to check for other options - the Hoover didn't clean as well but lasted longer, the Bissell cleaned well but died after a year. Then I found this unit, based on reviews and researching it some more it fit my needs. After receiving the unit the assembly was simple, took a couple minutes, and the design was great - very easy to access the clean and dirty tanks. What I really loved was the ability to remove the from plastic piece for suction which gave direct access to the rollers for cleaning. That was my biggest gripe with my Bissell - I could remove the piece, but unless I wanted to flip it over and remove the screws to access the roller directly there wasn't a simple way to clean it out. Performance wise, it simply cleans much better then both of the other 2 I had - that dual brush system works great, the Bissell was good but this was great (Hoover used the 5 spinning brushes which didn't clean deep). I had shampooed my carpet a couple weeks ago and just vacuumed the day before I first used this new one and I was pretty amazed at the amount of hair/gunk this dug up. The best part is that emptying it out and cleaning afterward is much simpler/quicker. Plus this unit is pretty cheap given the level of performance. The only real con for me is that the clean and dirty water tanks are a bit smaller than my Hoover had, but I can deal with that given the results. I would definitely recommend this product, already have mentioned it to family members who may need a new one. Glad I gave Kenmore a try as this was my first vacuum/shampooer I had ever purchased from them.

I've gotten some good use out of this, and overall I think it cleans well and has nice options given the size and price. You do sort of need to get the hang out using it to get the best clean, and to get a thorough clean you won't get more than maybe an 8x8 sized space done, so I would go with something larger if you plan to use this often or want to do large areas each time you use it. But, for smaller areas or the occasional larger area with a few fill ups, this works great. The attachment is pretty good as well and nice to be able to do both larger quicker upright cleaning and spot cleaning with the attachment. Only reason for 4 stars is it's not the greatest clean, but I don't know if you'd get much better without spending a lot more.

Absolutely amazing! Easy to put together and works like a magical charm!

I have low-grained carpeting that has not been professionally cleaned in over 25 years, (other than my own on-my-knees spot scrubbing). For decades, I have researched for feasibly priced machines, and seeing as I live in an apt. bldg. I couldn't imagine needing to deep wash the carpets again. However, with this baby and its extension hose and mini carpet nozzles I have cleaned our cat tree, sofa cushions, even the mattress. The emptying and filling of the water receptacles are not cumbersome to handle. I am very happy with this Kenmore and recommend it to everyone.

I am very pleased with this small yet mighty machine’s design and performance. Since both the tanks are located at the same level, the weight of the machine didn’t strain my arms. It cleaned better than my previous hoover brand machine. It is also super easy to put together and pull apart for cleaning afterwards. I only wish that the dirty water tank had more capacity, it has to be emptied once the level reaches about 1/4th of the tank’s level.

My carpet cleaner is about 7 months old but only started using it in the past few days. My partner used it twice before with no issue. Today I noticed a the clean water tank had a big crack and further inspection there were a few cracks. I emailed customer support and have since looked back on the product reviews. Take the word of many who reviewed that the product is cheap, it is!

Much better then the handheld I used, great efficiency, easy to use , easy to clean, the only issue is that in some areas grime accumulates and sometimes gets tricky to clean
