I love this little guy. We called it Wall-E because how could it be otherwise? It changed my home. We live on 650 sqm. ft. with two cats and a dog. (So not much space, can't tell how it fares in large living spaces) All animals shed like crazy and it just seems impossible to keep track of everything. Now I just hit clean on the app on my phone and when I get home from work my floors look beautiful. It really helped me reduce my stress levels by allowing me to use the time saved for other tasks, be it work, chores or fun! , but also the time I spend cleaning with the big one has halved. (I need to come up with a name for the big vacuum cleaner. It would be unfair not to. Maybe Dennis? We'll stick with the big guy for now.) I'll say it takes time to get used to WALL-E . The space around it doesn't seem to follow any particular pattern, but after a few tries you'll see that in the end he gets it all. The first few times he runs it will seem like a struggle (at least it was for me). But after about the third or fourth time, he seemed to be able to move around the apartment easily. He got stuck several times, but was able to free himself. It seems to transition well between different types of floors. We have carpets, tiles and rugs that he walks over with no problem. I haven't noticed an issue with the bin overflowing, but sometimes I'll stop it and empty it mid-clean just to be on the safe side. The battery seems to last about an hour and a half, which I think is more than enough time to get our apartment in order, but then again, if you live in a big house, I don't know if that will be enough time to to reach all required zones. In terms of noise, it's quieter than what I would call a traditional vacuum cleaner, but it's not entirely quiet. I think the noise level is low enough not to bother me when I'm watching TV or talking, but some people may be more sensitive to noise. I think it would bother me if I tried to sleep so I don't leave it running at night, but then again some people may or may not be bothered by it. Overall, I HIGHLY recommend this product. It's already saved hours of my cleaning life and I've only been using it for a week! I've also noticed a significant decrease in my husband's allergies so I think this is a huge help in the health and wellness department. If only he could wash dishes. :)
