I am very pleased with my new Dyson Gen5detect. We had a friend’s dog with us for several days and after they left I brought out the Dyson using the fluff roller and I was amazed to see so much on the floor that I didn’t see- the light showed crumbs, dog hair, miscellaneous stuff that could only be noticed with the light ! It was amazing to see the vacuum container fill. I enjoy cordless vacuuming- so easy to manouever around furniture. It’s worth every penny. I appreciate the videos too- I have a lot to learn and the videos let me learn easily.
