Have used it for 3 days. Would like some more time to actually offer an opinion. The 3 days I have used it, it is very handy. Was expecting it to be noisy, but noise is negligible, more a humming soothing sound. Usage - 3 days - Conclusion - removes dust easily. Will try out mop option in a day or two. What I have seen of it so far is it is worth the cost, saves time. Do not expect the powerful suction power of vacuum cleaners. It does what it is supposed to do.
