Okay I've only had it for a day so things should change, but I really hope it doesn't. I have my opinion never owned a robot vacuum or anything supernatural i think its definitely worth the money i have two dogs that shed like crazy and two kids that leave crumbs everywhere (seriously they are like magic!) i have too a wood burning fireplace so the amount of little chips/chips that end up on the floor is ridiculous! I already vacuum 2 times a day with my Shark vacuum so I was looking for something that could help a little (can't stand dog hair, haha)! I wasn't expecting a miracle worker to pick up every little thing and make me vacuum daily with my shark. Just something that helped a little! I'm pleasantly surprised at how well it picks up dog hair and crumbs! Exactly d as what i wanted! It also went right over my flat carpet and under my couch with no issues. He also pulled some lost toys out from under the couch which was great! Overall this is exactly what I wanted. If you're looking for something that will save you the hassle of regular vacuuming, you might need to look elsewhere! If you're looking for something to give you a little help, this is absolutely perfect!
