I've been in the market for a robovac for quite some, and, after a recent back surgery, vacuuming manually wasn't easy. I purchased this vacuum and have been very pleased with it. Its slim design gets under the dressers, beds, other furniture, and all the tight spaces that I couldn't get to with an upright vacuum cleaner. This makes a very low sound while in use, and honestly, I don't even realize it's operating, as the sound is pleasant (not loud at all).
