    Incredible 🎉
    I used this to clean my outdoor furniture, and I am so impressed!! I wish I had thought to take a before picture. It didn’t look awful, just all around dingy, but it was definitely dirtier than I thought! Once I cleaned it, I was blown away. It practically looks brand new now. The instructions were easy to follow, it’s easy to use, and it’s easy to clean. Just rinse everything at the end and then let it air dry. The suction is powerful, and the little bristles and a small bit of scrubbing worked great to loosen up stains. I can’t believe I waited so long to buy one. Best money I’ve spent in a long time. Worth every penny. This furniture has been outside maybe 8-9 months, and I live in a VERY dusty construction area and use the furniture almost daily.

    Did the Job!
    My dog has cancer. It sucks. It also causes more frequent pet messes. She’s vomiting more often and losing her bladder without warning. We already have an old Kirby vacuum (which turns into an unimpressive carpet cleaner) that just wasn’t cutting it and was also a hassle for daily messes. So I thought I’d try a portable.This thing did a pretty good job! It cleaned up today’s vomit stain no problem! We bought that rug last week to try and keep pee out of the carpet padding and it looks new again! I also hit our high traffic area where she often lost her bladder before adding the rug. We just “cleaned” that area two weeks ago and it’s embarrassing how dirty the water was. I will say that this felt like more of a surface clean on the high pile carpet. I have a feeling there’s even more dirt down deep, so we’ll see if this can actually tackle the smell long term. I also had enough water to hit a few couch cushions.Overall, I still think this was worth 5 stars! I do wonder how it’s different than using a wet vac with a bucket of warm water. This is definitely more convenient, but also more expensive. I did find the instructions a bit confusing. I thought that there were two different cleaning modes (self spray vs continuous spray) and I couldn’t tell a difference in the instructions for each.

    Great for rapid response spot cleaning!
    We adopted a 12-week old puppy exactly a week ago as I write this review. She hasn’t been housebroken due to bitterly cold temps and deep snow for her first weeks of life outside her mom’s insides. So we have been lovingly teaching her the ropes but there are bound to be issues with a new puppy in a new-to-her house.We have a full size carpet cleaner but it is definitely not convenient for quick cleaning potty spots. It’s better suited to do a full scrub a couple times a year. I ordered this Bissell protable model after comparing reviews on about a dozen machines and brands.I do not regret one, now defunct, penny of this purchase. It is so much easier to rapid respond to her accidents than the big carpet machine.Pro tip: get a small blacklight/UV flashlight and you’ll spot old stains as well (puns intended). Dog urine and vomit glow a faint green black light. The glow is obviously stronger in a darkened room versus a sunlit room.Today I was on the hunt for my puppy’s glowing gifts with my shades & curtains drawn, trusty blacklight flashlight in hand and my new little sucker machine filled with its magic peepoo potion.This little black and green beast made short work of my prey. The sample bottle of solution easily handled every stain I found. I’m gonna pick up a big jug of the stuff to use in the full size cleaner as well as the portablePros:The included solution did feel like a bottle of magic potion. It cut through old stains that I found we’d missed from our previous puppy training 2 years back (gross I know)The long power cord is great for adding the ability to move around the room while hunting for old missed stains.The small suction/scrubber head is perfect for literal spot cleaning. I haven’t used the bristle attachment yet but the rubber “fingers” cleaning attachment was great to really get in and scrub carpet stains with vigor.Portability is outstanding. Even with a full solution tank the entire unit feels lighter than a milk jug. The carrying handle is ample room for my meaty paws.Filling, emptying, and cleaning is very simple and easy.Cons:The suction head did seem to clog easily. If you’re cleaning dried stains then I highly recommend a good vacuuming first. My older dog’s short hair quickly covered the suction inlet.Also I do wish the suction was a little stronger. I followed the instructions to keep taking passes over the scrubbed area until I no longer saw liquid being sucked up. But by the time the solution tank was empty I only had maybe a cup of dirty liquid in the other tank. Seems like roughly ⅞ of the solution is still in my carpeting, pad, and subflooring despite multiple suction passes.The unit is a little top heavy. I accidentally knocked it over twice during my first use. Some.of that is due to the next con which is the hose. The coil is a bit too tight to easily stretch/reach without pulling the unit. So be mindful of your reach and machine location at all times.A change I would recommend to Bissell is to have a silicone cap or wedge that can be used to briefly block the suction port when needed. I recommend it for at least 2 reasons. One is that the head leaks as soon as you turn off the vacuum motor. So being able to block the opening would be convenient over wiping up spills. Second is that the suction head’s self cleaning function worked a thousand times better when I simply put the edge of my palm against the suction opening for a second or two while I held the head up and gave a quick spray against my hand. That was enough to completely clean the debris built up in the head without having to dismantle it while I was cleaning.

    Habia adquirido el modelo Little Green regular y me lleve una decepción muy grande, a pesar de que es muy bonita estéticamente, deja mucho que desear en cuanto a poder de succión y accesorios.La Little Green Max al ser por muy poco más cara que el modelo base tiene un poder de succión excelente, la boquita con cepillo que tiene es más grande por lo que abarca más espacios y hace la limpieza más rapida, hasta el cepillo se siente mucho mejor al momento de tallar tapiceria.Muchos se quejaran de que su tanque no es tan grande, pero no te lleva mas de 3 minutos volver a rellenarlo.Y me encanta que este modelo si puedes limpiar tanto el tanque de agua sucia y la herramienta de succión, donde en el modelo original tenias que utilizar agua a presión para poder sacar restos de suciedad y hasta eso no se podían limpiar por completo.Tal vez no es tan bonita como la original, pero al ser más compacta, más potente y más facil de limpiar, me deja satisfecho con mi compra. No me arrepiento de haber devuelto la original y haber comprado esta.

    Estoy más que satisfecho con la aspiradora, super fácil de usar y quito manchas que estaban desde hace más de 3 años. Vale totalmente la pena

  7. Humberto Velazquez

    Hasta ahorita le he usado 2 veces y me gustó mucho, hace su función muy bien

  8. Martha Cabrera

    El producto muy bueno y muy facil de usar. Me sirvio mucho para lo que lo necesitaba (asientos auto).El trato del vendedor bastante malo. Solicite factura y nunca me contesto. Este producto lo compre ya que lo podia meter a mis gastos de mi carro pero nunca me la mando y no me contesto.

  9. Killerbunniez

    Es muy pequeño pero potente, limpie un sillón que tenía años sucio, wow salió puro lodo, le di como 7 pasadas hasta que quedó limpio. Está aspiradora realmente funciona de maravilla. Estoy muy satisfecho con mi compra
