I had to empty it 3x just from vacuuming the stairs (17 steps). My large 22x26 room I emptied 5x. I'm impressed with it's handling of dog fur (Husky) as well as how much small dirt/dust particles it picked up. Sucker's got some power! As advertised, it is pretty quiet. Quietest vacuum I've ever used. I was worried about the collection bin being too small with having a long hair dog, but with that power comes compression inside the bin so it's able to pack quite a lot into that small space.
Almost $300 bucks is no small amount, especially for a vacuum. I was very leery & hesitant to pull the trigger on this one, it being a brand I've never heard of before. Tineco can thank Consumer Reports for earning my business, as it was recommended by them over Dyson due to Dyson's decline in quality & reliability apparently. I'm only giving it 4 stars because it doesn't feel the most sturdy in my hands, not like a typical upright. This is my first stick so I'm probably just not used to the lighter design & style. It does feel well built, just not solid. Then again they are all removable attachments & parts so that's probably par for the course for a stick vac.
For now I feel it was a good buy. I say "for now" because I haven't even had it a whole day yet. I will follow-up as I put some more laps on it & get a better idea of it's overall quality & versatility.

Holy crap does this thing pick up a LOT more dirt than any of my previous vacuums! My previous vacuum (Dirt Devil upright) could do the whole house & at most I'd have to empty it once. No joke, I have filled a 13gal tall kitchen can/bag!! Mind you most of it was dog fur, but still WAY more than the upright ever picked up. The bottom of the bag was all gritty sandy dirt, about 6" deep worth! I've NEVER had a vacuum pick up so much, let alone how effortlessly it does so. I live in a 3K square ft house, alone with just my dog. I bought it brand new 4yrs ago, no kids have ever been over, I never wear shoes in the house. I have absolutely no idea where all that dirt came from, let alone that my previous vacuum left that much behind! I'm absolutely amazed by this things performance! Will update on quality after more use, I've only had it since yesterday.

Still very happy with this vacuum. Played with a friend's Dyson & I can say my first impression about it feeling toy-ish & un-sturdy is related to the style (cordless stick) & not a reflection of the Tineco A11 vacuum so I am adding the fifth star I withheld because of my first impression.
Also.. some reviews are complaining the bend at the base of the power head preventing it from going flat to vacuum under furniture & this is not true. All you have to do is turn the vacuum a quarter turn so the power head is on an angle & it drops completely flat. (Photo & video attached.)

So I feel the need to counter the reviews here that complain about loss of suction after only a few uses. CHECK THE FILTER!! As I mentioned about how much this thing picked up that my Dirt Devil left behind, & how much of that was fine gritty dirt, well.. it caked the cleanable filter REALLY quickly! The tool they include to clean the main filter is included for a reason. I've had to clean the filter about a dozen times in 4 months. With a freshly cleaned filter I just ran over a penny & the vacuum sucked it right up, & that was in normal mode NOT on max.
The filter is stupid-simple to clean. It literally just slides in & out from the middle of the collection bin. I've started the habit of pulling & knocking it on the side of the garbage can whenever I empty the bin. It literally only takes 2-3 seconds to do.. I only use the cleaning tool about every 10 days to get the extra fine dirt off if it. (And yes, they do include a 2nd filter to swap into the vacuum before using the cleaning tool, you're not running the cleaning tool filterless.). The engineers really did go the extra mile to make this very user-friendly, an excellent performer, & easy to keep in optimal condition to maintain that performance.
4 months in & I still highly recommend this vacuum!

Still going strong! I now knock off the fine dust particles from the filter every time I empty the collection bin. I literally vacuum 1x-2x daily so I've used this thing at minimum 200x & suction power has not declined.
