About this product

Product Information

With its powerful LED headlight, the gray Kirby Sentria G10D lights the ground as you vacuum, making sure those dark, hard-to-reach spots, like under your furniture, are clean. The HEPA 11 filtration system is great for those with allergies, and the powerful airflow ensures a deep clean no matter whether you're cleaning carpet or hardwood flooring. The Kirby Sentria comes with a number of attachments, including a furniture tool, floor brush, and even a ceiling brush. The vacuum can be used either as an upright device or, by using the included hose attachment, you can transform the vacuum into a smaller canister vacuum. In addition to sucking things into it, the Kirby Sentria G10D can also be reversed to push things away from it, perfect for clearing your patio of leaves.

At first I was disappointed because they sent the wrong item, but this is why you should always have open & clear communication between buyer & seller: I contacted them & they realized their mistake. What they reshipped was BETTER than I imagined: NEW OLD STOCK. As in, brand new, never even taken out of its box before, never brewed a cup of coffee for anyone else until me. I LOVE IT. Thank you. Great deal. If you have more, I'll buy another.

    I love it but am still learning how to use it... it will take a while but I knew what I was purchasing.. a multi cleaning reliable tool..

    I bought it refurbished less than 1 yr old. Looked brand new, Got here quickly and in good condition. I put in together in about 30 min. I have just been doing basic vacuuming so far, but have started some videos on line to learn all that this machine can do and how to do it...

    Bad vacuum, had to pay to have repaired

    This Kirby was reportedly “tested.” That was very far from the truth: had to pay $100 from the Kirby repair shop, engine brushes were bad as was the cord. The vacuum wouldn’t start. Once repaired it runs well. I would advise those buying a used Kirby get one from a dealer, repair expert or have video proof that the unit works. Once obtained take it to a Kirby shop—a few dollars to clean it up well worth it. In the end the sellar refunded the cost of the repair.

    Sturdy vacuum that you know is not going to break down. All pieces and attatchments included

    We have owned only one Kirby in the past. We have also owned only one vacuum in the past. Our Kirby. It lasted over 20 years; cleaning up after 3 very busy boys tracking in dirt and mud, along with their friends, pets (not to mention a husband). I knew it was getting old, and my husband kept telling me we needed a new vacuum. I told him I was not going to buy a vacuum unless it was another Kirby. They are so reliable, they suck up dirt on your carpet that you didn't even know that was there. They have an attachment that can vacuum hardwood or laminate floors. It can clean your drapes, or blinds. It can do a lot believe me! If you have never tried a Kirby, you should get a demonstration before you consider any other vacuum on the market today. It is easy to use, it has hepa ...

    Yes it's heavy, but won't need to buy a new vacuum every other year, or duct tape to keep it going.

    This vacuum works great. I was surprised how well it worked. Liked it so much I bought another. I inherited my first one a couple of years ago, but due to it's weight, we only we used it on the 2nd floor. It's not suitable for young kids to take up and down stairs, but should not be a problem for the average adult or teenager. With the assisted drive feature, it's weight is not a facter while sweeping. Although it doesn't have a integrated hose on the side, this vac cleans the edges so well, you really don't need it. If you do attach the hose however, the suction matches a shop vac, which is much better than the store vacs. There are also some interesting attachements. I don't think I will use all of the different ones there are, but there are some really nice ones depending on ...

    vacuum cleaner by kirby

    this unit is very powerfull but also has a very high winding noice, this is caused by the motor running at a high speed and in turn the blades forcing the air thtough will produce this high pitched sound,very uncomftable & bothersome. the unit is also heavy especially if you have to carry it up or vacuum stairs etc. otherwise it does the job well, this are the reasons many people that bought this type of vacuum cleaner will get rid of it in my opinion.
