Question: how does it do stairs
Document: easy to clean small messes ....great for stairs and furniture  easy clean out too...great value for the money I highly recommend this portable cleaner
This is cheaper and lighter than a lot of other cleaners. It is the only one I can easily carry up the stairs. works great as a spot cleaner, does a decent job cleaning the stairs. Only con is that it takes hours to charge and only works for a few minutes.
I bought this so I could more easily clean my carpeted stairs. Unfortunately, while it could spray the liquid out, it didn't suck it back up. I was only able to collect about a tablespoon of liquid back into the machine. It seemed to only have about as much power as a dust buster.
This unit is great for those spills on carpet and furniture, and also for pet owners. My old one ssuddenly died after being used almost on a daily basis for a number of years snd the new one is even better. It is also great for cleaning carpetetted stairs.
it is perfect for cleaning up small spills or puppy accidents. if you have a large area to clean, i would suggest going with a bigger plug-in sort of cleaner, but for small to medium stains it is perfect. it is light weight and handheld so you can carry it to different rooms, and up stairs with ease. it holds a good amount of solution, and i haven't had a problem with it not holding enough dirty water.
some great reviews here...I always struggle with bringing out my big carpet cleaner, which has a small hosed floor attachement.... such a hassle, and huge water dept. to use, etc. This little cleaner makes a small clean up a breeze.... easy water compartement to access, clean, no hoses, easy storage... and of course, perfect for stairs.... kudos to Bissell
I just received this today after waiting a week, I was so excited to clean my stairs this weekend. I have listened to other consumers, this is HORRIBLE!!! The water tank has to be held on with one hand while you try to clean with the other, the brush falls off and this thing leaks, all of this within the first minute of &#34;trying&#34; to use it. I will be sending back on Monday!!! Don't buy this product.
You may need more detergent to thoroughly clean that up.-Dirty water reservoir is sometimes hard to detach for emptying. I've had to press the detach button a million times for it to actually detach.Overall, it's great for cleaning up dog pee in SMALL amounts, or for doing a quick clean on your stairs. Other than that, my Hoover Steam Clean has everything I need & this thing has now sat in the laundry room!
This spotlifter is a great product! It worked so well at removing stains in my car and on my stairs! It was not only easy to use buy required no assembly and I didn't even have to read the directions! This is a great product to have around the house becuase spills happen all the time at my house with kids and pets! I am really glad I bought this product and would recommend it to anyone who is thinking of buying one!
Nice product for small areas like stairs. Only thing is I had to refill the solution reservoir twice, but then again I had some stubborn stains on several stairs. Was able to clean all my stains on one charge. Only complaint is you can't spray the solution unless the machine is on. Would've like to spray the stains a little before hand.The suction is o.k., just have to press down some to make sure getting all the solution.
Answer: Manual unit. you spray your area with the solution, scrub with the brush, and suck up the dirty water.
