Dyson’s cordless range runs from the V15 Detect to the newer Gen5 models. The Gen5detect is the smaller, easier-to-handle one. The Gen5outsize adds a much bigger bin and a second battery for large homes. Whichever you pick, a listing should name the exact model and the heads included.
Gen5detect or Gen5outsize?
Both Gen5 machines list up to 70 minutes of run time per battery on low power, use the same battery and take about 4.5 hours to charge. The differences are size and extras.
| Spec | Gen5detect | Gen5outsize |
|---|---|---|
| Bin | 750 mL | 1,900 mL |
| Batteries in box | 1 | 2, plus a second charger |
| Floor head | Motorbar | Motorbar XL, a wider head |
| Weight | 7.7 lb | 8.6 lb |
Both come with the Fluffy Optic head (green laser), a motorized Hair Screw tool and a Combo Brush, and both count particles to adjust suction automatically. The bigger head on the Outsize covers more floor per pass, with slightly less suction.

Where the V15 Detect fits
The V15 Detect is the earlier laser model. It has the green laser on its Laser Slim Fluffy head only, plus a screen that shows battery life. It has no auto-empty bin. The Dyson V15 Detect page goes through it, and the Dyson Black Friday hub lists the rest of the brand.
Match the vacuum to the house
A small flat with hard floors suits the lighter Gen5detect. A large house, or a home where one battery rarely lasts the whole job, suits the Gen5outsize and its spare battery.
