Which suits a terrace, a flat or a family home
For a flat or a terrace with hard floors, the Gen5detect is easier to carry up stairs. A large semi, or a home with several pets, makes the Outsize and its second battery more useful. The wider XL head covers more floor but gives slightly less suction.
The V15 Detect sits below these two. Its green laser is on the Laser Slim Fluffy head only, and it has no auto-empty bin. The Dyson Black Friday UK hub has the rest of the brand.
