If you've not bought yet then do some research before making that purchase. If you plan on buying something to pass down to your children or run a cleaning service maybe you need to spend $2000 on a vacuum cleaner.
But if there are less expensive models, brands or products that will meet your needs then maybe you should make your purchase differently.
Look at reviews of the different products that you are interested in. A few bad reviews don't mean the product is bad or their service is bad but if you find hundreds or thousands of bad reviews
then you should probably look elsewhere.
If you don't know how to do a search go here and ask a question
. You can even ask for an opinion there if you like.
If you find that the high priced item is what you really need then by all means buy that one.
