I've tested almost every Dyson vacuum – these are the deals you should buy this Prime Day

There's a third off the V15 Detect Plus at Amazon, which is a very strong discount on this model – it's very rare to see it this cheap. The V15 Detect is the third-best cordless model based on specifications, but I think it's the best Dyson vacuum for most people's needs. It offers advanced features like dust particle sensing and automatic suction adjustment, plus a dedicated Fluffy cleaner head for hard floors. This version comes with a range of useful tools, but if you especially want a low-reach adaptor, which allows the wand to bend forwards to clean under furniture, head to Best Buy and pick up the V15 Detect Extra for $599.99 (was $849.99).

The V15s has a massive $200 off right now. That's not quite the cheapest I've ever seen this model, but it's still an excellent discount. This is the V15 – which is one the most advanced, tech-packed and high-performing Dyson vacuums – but with an extra mopping floorhead bundled in to take care of wet cleaning on hard floors. Head to our Dyson V15s Detect Submarine review to find out more. This same discount is also available at Best Buy and direct from Dyson US.

There's a massive $150 off the V11 Origin at Amazon right now. That's an excellent discount on this model – it's very rare to see it cheaper. It's also an official 'Prime deal', so you should be good to buy now without fear of a bigger discount appearing later in the week. This is an older model in the Dyson cordless vacuum lineup, and lacks fancy features like dust particle sensing, but it's still supremely maneuverable, with strong suction and a useful LCD screen. It comes with a selection of detail tools.

There's $200 off the Ball Animal 3 when you head straight to Dyson. This upright vacuum is heavy and bulky, but boasts an incredible amount of suction power. If you want something that can handle a seriously deep clean, it's an excellent choice.

There's $150 off the V8 right now. That's a big discount but I've seen it go for less on a number of occasions. I'd recommend waiting for Prime Day to kick off properly in case a stronger discount appears. The V8 cordless is the oldest model in the current lineup, but it remains extremely popular, thanks to its simple but effective design, with strong suction and great maneuverability. This version comes with a motorized hair screw tool for cleaning furniture.

This supersized Dyson vacuum has a supersized discount in the brand's own sales event, with a massive $200 off list price. It's not the cheapest we've ever seen this model, but it's still a strong price-drop. The Gen5outsize is based on the Gen5detect – with the same hi-tech features, including advanced particle detection and automatic suction adjustment – but with a bigger dust cup and wider floorhead.
