My MooSoo vacuum that I bought from Revain was a bit dusty but I liked it even though it worked very well so I thought I'd buy another. I was sad to see that Revain is no longer wearing MooSoo. I bought it after reading some reviews, mainly because of the strong suction power. Wow. It sure is even better than MooSoo. The suction power is actually almost as good as that of a corded vacuum cleaner. The MooSoo suction power was adequate, which is impressive. It's heavier than the MooSoo and not as easy to handle, but the superior suction power makes up for it. The cordless vacuum cleaner is very practical. Instead of vacuuming with a Dyson once a month, I vacuum it every day and sometimes multiple times a day to keep my carpets looking good, as well as my hardwood floors and kitchen floor. However, there are some inconveniences. It needs to be emptied and cleaned frequently. When the filter needs to be cleaned, the vacuum cleaner turns itself off as if its battery were dead. So you really need two filters because after washing one, you have to let it dry for 24 hours. It comes with two filters. Some reviewers have complained that they only have one. Well look closely. It's somewhere in the foam. I didn't find it at first either. I went ahead and bought two extra filters just in case. The instructions say you can empty the canister indoors with a plastic bag. I was skeptical but I tried it and it works. Although it needs to be emptied frequently, I no longer have to go outside to do it. It's nice. The fact that it stands up on its own seemed like a minor feature, but I found myself enjoying it immensely. Time will tell if I'm tired of washing the filters or if the battery is dead. But now I am very, very happy with this vacuum cleaner. I can't think of any others that are as good, although some of them cost a lot more.
