I had to let my bi-weekly cleaning person go due to the cost. I am a retired senior and wanted a cordless heavy duty vacuum that was easy to maneuver. I had a great corded vacuum, but I hated dragging the cord around and it was so heavy. I was able to sell that one actually to my previous cleaning person. I did a LOT of research on the different cordless vacuums. All brands and models within each brand. This one got a lot of great reviews.
So for my 70th birthday, I put it out there that I wanted Amazon gift cards so I could purchase the Tineco Pure ONE S15 Pet Ex. I had a lot of very generous friends and it didn't cost me a dime! The vacuum is great. Right out of the box I loved it. I have 4 cats, one is long haired, so I use it almost every day to keep up with the cat hair especially now during "shedding" season. This is so much better than lugging out the corded one and lugging it around my condo and tripping over the cord. I live in a 1200 square foot condo with one wall to wall carpet and several area rugs. The rest is hardwood floors.
I have no issues with the battery running out before I am done. I do have the extra battery which I've only had to use once when I was doing "spring cleaning". Usually, I have more than 30% battery power left. It recharges quickly. It is great on hardwood floors as well as the carpets.
The only complaint I have is the location of the on-off button which is on the bottom of the handle where you grip it. Sometimes I hit it and it turns off. Getting used to staying away from the button while I vacuum. I understand the other popular brands, you have to hold in the button while you use it which I didn't want.
While it is much quieter than my corded one, my cats don't like it any better!
It is a little top heavy, but I guess all the cordless heavy duty vacs are. You have to make sure to prop it up against a wall while you move furniture, etc. or it will fall over.
I've used the motorized upholstery attachment to do my sofas and DR chairs. It worked well.
As you can see, it fits very nicely in my "cleaning" closet which has an outlet for my rechargeable tools.
I know it's a bit pricey, but if you can afford it, I would highly recommend it.
