Boulanger is offering the Dyson V12 Detect Slim Absolute for 449 € as part of its autumn clearance, a 200 € discount from its reference price of 649 €. This cordless vacuum weighs 2.4 kg and includes a dust-measuring sensor that shows real-time dust levels on an LCD screen. It sits in the middle of Dyson’s cordless lineup, between the V11 and the V15, and is designed for smaller homes with hard floors. Boulanger, which handles the product’s sales and shipping, lists it at 449 €, a 30% discount. On October 9, none of the other ten merchants listed by LeDénicheur offered a better price. The Dyson V12 Detect Slim Absolute is targeted at users who want a lightweight Dyson without paying for the top-of-the-line model. It is nearly 600 g lighter than the V11, making it easier to handle when lifting it to clean high areas. The Fluffy Optic brush lights up hard floors to reveal fine dust, while a piezoelectric sensor counts the particles and displays the result on the screen. A single button press starts the suction continuously, and users can switch hands without turning off the motor. The Fluffy Optic brush is designed for wood and tile floors, while the Motorbar brush is used on carpets and automatically untangles hair and fur. The vacuum’s Hyperdymium motor spins at up to 125,000 revolutions per minute, providing 150 AW of suction power. After removing the tube, the mini motorized brush and long suction hose are ideal for cleaning sofas, car seats, or areas behind radiators. A wall-mounted charging station recharges the device in 4 hours and also stores its accessories. Dyson claims up to 60 minutes of battery life in Eco mode, though this decreases in more powerful settings. The V12 Detect Slim Absolute may not be ideal for large homes or households with multiple pets, as its 0.35-liter dustbin fills up quickly. It does not compete directly with the Dyson Gen5 Detect Absolute, which offers more suction power but is heavier. The V12 sacrifices some power for lighter weight while keeping the dust-revealing brush and sensor. Under 300 €, the Dreame V20 Pro offers HEPA 14 filtration and 72 minutes of measured autonomy. The V12 fits between these models for users who prioritize ease of use. Its strengths include a 2.4 kg weight, a sensor and LCD screen that show dust levels, a Fluffy Optic brush that helps detect fine dust, and a repairability score of 8 out of 10 with spare parts available for 13 years. However, its limitations include a smaller dustbin, 150 AW of suction power, an on/off button placed away from the screen, and a 4-hour charge time. Sold and shipped by Boulanger, the Dyson V12 Detect Slim Absolute was the lowest-priced option recorded by LeDénicheur on October 9, at 449 €. This price makes the V12 a more affordable Dyson while keeping the key features of the Detect line: a brush that reveals dust and a sensor that measures it. At 449 €, it is 250 € cheaper than Fnac’s listed price of 699 €. For an apartment with hard floors and a few carpets, it is a logical choice. However, those with large homes or a long-haired pet might be better served by a more powerful model with a larger dustbin.
