Q: This product is completely useless. It has no power at all and doesn't clean well at all. Even if it worked for my room I wouldn't use it. I wish I'd returned it. I'll go with a different brand next time. If you want to get the best one, you'll need one that actually works better. That way, it's worth buying in the end.
A:
Bad review
