Question: how do you open it to change the bag?
Document: Why? Because the bag fills up very quickly and loses suction shortly after. I have to change the bags when they are only 1/4 to 1/2 of the way full. What a waste of time and money! After putting in a new bag, I can use it for 1 large room. Then I can actually hear the suction on the machine change and its cleaning power diminishes greatly. After just a little bit of cleaning, it's time for a new bag.2.
Super vacuum. Bought this as a floor model and it was almost like new. Handy attachments. The power head is very useful and it is easy to change from one head to the other. Easy to pull along. A bit on the light side as it sometimes does the &#34;turtle&#34;, tipping over and landing on its back, wheels up but can easily be flipped over with a foot. Retractable cord is a good length for most rooms.
Also the "bag full indicator" that Kenmore touts never worked, not even from day one.4. The brush head performs poorly on carpet and rugs. I tried it on our one bedroom which has wall-to-wall and on our area rugs, and the suction was very weak, even with an empty bag.
This may not be a good vacuum cleaner if your home is fully carpeted (the brush head is just plain useless on carpet), but my home has all wood and tile floors. This is easily the most powerful vacuum I've ever used.The suction is so fierce, with a new bag you can lift a small child or pet directly off the floor.
With a new bag, yes. But as I've shown above, a new bag fills up very quickly and you will have to replace it when it's only 1/4 or 1/2 full.After giving the Kenmore Magic Blue a fighting chance, I can only give it one star.This year I will be buying the Hoover Multi-Cyclonic Canister Vacuum because:1. It's in the same price range2.
The cord though is short also the vac can be loud and if your not a bag person you won't like it. I am a bag person don't like dust in my face. Just recently mine has been spewing dust out the back and has to be replaced. My husband says I should break down and buy a good vac maybe pay a little more for one. You get what you pay for. Like a dyson canister but I don't agree.
I have owned this vacuum for about (5) years. Not bad for 90.00. There are tons of heads that fit this vacuum so you don't necessarily have to use the one it comes with. It has fantastic sucking power when the bag is empty. Gets into tight corners like behind your toilet and under furniture with ease. Great on hardwood floors but does not deep clean your carpets and does not have a lot of attachments. I wouldn't recommend it for a really large house the bags are small.
I love that this is light weight. It is the perfect size for a small house. It has a powerful brush, smooth extendable wand and large rollers for easy toting. It's durable and powerful. Easy to replace the bags- even has an indicator for full bag- and really easy to clean. You can pick the floor settings for floors or carpets and adjust the power as well (that controls how fast the brush spins). Strong suction. I find this works wonderful on both carpet and floors.
this vacuum's suction is so powerful that i often need to turn it down!i drag this little guy back and forth from my gift shop to the house....love it!
this is a great vacuum but this one I received from another customer as a second hand didn't have all the parts and the manual.
Answer: Its so easy! You lift this lever that is in the front of the vacuum, and that lifts the lid to where the bag is kept. Using the Amazon picture as a reference, this lever is on the top, just across from where the hose attaches to the body.
