Just got this today and have only run it twice, so here are my first thoughts-Single floor apt, ~750sq ft, 3 cats- Mapping feature in the app is incredible. My precious vacuum (Coredy brand) would run randomly, and did not map anything. It was decent, but missed spots frequently. In comparison, the Q5 has an app that does an incredible job of mapping your home- you can mark off “no go” zones, distinguish rooms, mark off where furniture is. You can check the map at any given time to see what has been vacuumed, what is left, and where the Q5 is. The vacuum essentially outlines the perimeter of a room, and then does lines back and forth to get all areas inside the perimeter. You can schedule cleanings (for full home, or certain rooms, and can also adjust modes to be max mode, quiet mode, balanced, etc) or just click a button to start a cycle at your own leisure. Outstanding.- Suction is impressive. Compared to my old one, this one is PICKING UP some stuff. Haven’t yet experienced it sucking up something it shouldn’t (shoelace, electrical cords, etc) but I’m also in the habit of keeping those off the floor so my vacuum can run without issues. I have 3 cats so there’s a lot of loose cat hair, Q5 seems to grab all of it.- Voice alerts is another neat feature. The vacuum speaks up (in English, but app gives option to change languages which is great) to let you know things. Not sure what all it announces yet, maybe if the battery is low, vacuum is stuck? So far I have heard it tell me when it’s done cleaning, and then when it’s made it back to the dock and is successfully charging. Pretty neat.- Noise level- this one isn’t 5/5 stars, but I’m ok with it. Definitely louder than my last vacuum (maybe is equivalent to an older blow dryer). However, it’s not TOO loud, and I don’t mind the noise as that probably indicates very good suction. A fair trade off.- Size - one tiny gripe would be the height of this unit. I’ve had “shorter” robot vacuums before that were able to get under my coffee table, but this one can’t. Not a big deal, but do note that this unit may be a tiny bit taller than you’re expecting.- ONLY CON that I have found so far is the dust bin. That baby is small. Like, weirdly small. My previous vacuum died on me last week, so I ordered this one and didn’t vacuum for 3 days (I wanted to give the Q5 a challenge lol). On the Q5’s first run, it PACKED the dustbin. I ran it again a few hours later and it was filled again. I do typically run my vacuum daily, so once we get things managed over here it may not be that big of a deal. But if you have pets or you shed like one, and you don’t plan on running this daily, you might have an issue with the size of the dustbin.- Battery life- unsure as of yet, will update this in the future.- Carpet work is solid. I have a very low pile rug that it handles effortlessly. I have medium pile carpet in my bedroom, and while I know nothing will replace a real vacuum (shoutout to to Miele canister vac!), this is still pretty effective. It even leaves faint vacuuming lines in my bedroom carpet, which my old robot vacuum NEVER did.Overall I’d give this a 4.6/5, but since half stars aren’t an option I’ll put it at 4. I do like this a lot, and to be honest I was a little skeptical of all the 5 star reviews, so I’m doing my part to sing its praises *realistically*. But after doing my research and settling on this model, I’m very pleased. Please note that this brand has other vacuum models, including some that I think may mop or even empty their dustbin themselves! Very cool, but since I live in a small one bedroom apartment, I couldn’t justify the price for those features.Other note- I really, really like the app so far. Very informative, and I found it intuitive and super easy to navigate. Vacuum itself came with a quick start guide which made it supremely easy to download the app, connect the vacuum to the app and then to wifi. Smart devices are supposed to make our lives more convenient but we all know that’s not always the case (I’m looking at you, Litter Robot). I think the app and setup guide to this vacuum are 10/10.Photos— 2 pics of an old sponge in the Q5 dustbin for scale. It was the first universally sized thing I could find for comparison, lol. Also pictured is a masssssssive clump of cat fur and dust that the vacuum picked up on its first run. Last photo is of one of the mapping modes on the app.
