Central Vacuum Cleaning Systems
Are they good? Have you heard of KIRBY? Their salesman come to your house. I think its a cannister type vacuum that sells for around $1500. Anyway, we tell them we have a central vac and they simply go away. They know their vacuum can't compete.
The filters are better than a regular vacuum. And the unit is in the garage! No more bags to worry about.
And you won't have to sweep much for a while. Our kids, friends, relatives all had to try it out when they came over. Its almost as good as getting paid to let someone paint your fence.
