Hi

The DC04 Dyson has a filter at the top, but the DC07 has one at the side on the bottom and one underneath the cylender.

Take all the parts off your dyson and throw them in the washing machine and then put them back together

If it won't latch after cleaning the latch and making sure that everything is seated well, get in touch with Dyson, they're great about making things right with their vacuums.
