Yes, i heard many about Pro-Aqua brand that has manufacturing various featured vacuum cleaner and many other home appliances. It's really a nice brand option for buying a new vacuum cleaner because it comes with latest technologies and also in affordable price rate.
Delphin and rainbow both are good brands of vacuum cleaner so, it's very difficult to say that which one is the best from delphin and rainbow. I am using ranbow's vacuum cleaner for cleaning at my home and i think, it's much better and cheaper than delphin in cost and features.
If you are looking for a good vacuum cleaner for removing dust from sofa and beds, then there are so many standard brands option available for you. Delphin, dyson, dust care and rainbow these all are standard brand of vacuum cleaner and that's worthy choice as a home vacuum cleaner.
