This vacuum cleaner was purchased in August 2017 and it is now the 1st November 2017 and it won't be one more Charge. I was very careful, changed filters regularly and emptied the bin as soon as I got home. I tried troubleshooting with the manual but it is very poorly written and clearly written by someone who is not familiar with English. First I liked this vacuum cleaner, it picks up dog hair very well! My floors looked great. However, it hung on a very small doorstep between rooms (we all have hardwood with no carpets), sometimes I would find it under the bed, sometimes under the dining table for no apparent reason other than having to charge it because it wasn't going home on its own . I actually attached a "Tile Slim" to it so I can find it when I get home. In summary, if you are looking for an expensive vacuum that will work great for 3 months then this is the one for you. If you want it to last longer then this is not for you (or me who is currently requesting a refund). REFUND REQUEST UPDATE - NO RESPONSE. Read a lot online about this defunct company, very bad reviews, not willing to replace or refund. Now I'm very worried. I pray that Revane will help me with this.
