Having major building work at home at the moment. Whole house is covered in thick plaster dust despite dust sheets etc. We already had to have our dyson repaired after the past lot of building work as the plaster dust is so fine it totally clogged the filter and engine. I've noticed that builders seem to use the Henry vacuum cleaners - does anyone have one of these? Is it because they are just tougher than other cleaners? Or are they designed for building mess? I don't really want to get in professional cleaners for the carpets as we are planning to replace them sometime next year. Any suggestions?
