Forget Black Friday, tons of Shark vacuums are down to their lowest-ever price for Prime Day – here are the 10 best deals to buy

With 37% off, this vacuum is at its lowest-ever price at Amazon. The Detect Pro used to hold the top spot in our best cordless vacuum guide, and one of the main reasons it was demoted is because of rising prices. The version on sale at Amazon looks to have a different floorhead to the one we tested, but other than that boasts all the same features and benefits: it's lightweight, nimble, and smart, with a plethora of useful automation features.

With a third off, the Shark PowerDetect Cordless is back down to its lowest-ever price. Based on specs, this is the best Shark cordless vacuum you can buy right now, and in our Shark PowerDetect Cordless review we were impressed with the intelligent features – this vacuum can sense floor type, dirt levels, and the edges of rooms, and intelligently adjust suction in response. The floorhead is excellent at dealing with chunky debris, too. Want something even cheaper? The corded version of this vacuum also has a major discount.

With 33% off list price, this corded stick vacuum is down to its lowest-ever price, and an absolute steal right now. The PowerDetect can auto-adjust brushroll speed depending on whether it's on a carpet or hard floor, and it features Shark's new-style floorhead, which is especially good at dealing with chunky spillages. Cords might feel old-fashioned these days, but they have their benefits: corded vacuums tend to deliver better suction than cordless ones, and have a longer overall lifespan, too. Plus, you'll never have to worry about running out of juice.

The HV322 Rocket Deluxe regularly attracts price drops, but this deal is especially strong. If you want to save money, opting for a corded vacuum is a great way to do it without compromising on performance – corded vacuums almost always offer more suction than cordless, and tend to last longer overall, too. I haven't tested this specific model, but it looks like a good, basic all-rounder, and for under £130 it won't break the bank, either.

The IX141 is a cheaper model in Shark's lineup, but it's especially wallet-friendly right now. There's 50% off RRP, which takes it to the cheapest price it's ever sold at. We haven't tested this specific model, but it looks like a basic but effective cleaner, with LED headlamps on the floorhead and a design that can be folded up for convenient freestanding storage.

This cordless stick vacuum just dropped in price again, and it's now at a new, lowest-ever price. While we haven't tested this specific model, it looks like a decent, budget-friendly choice. It can sense floor type and adjust the brushroll speed to suit. You'll get up to 40 minutes of cleaning per charge, and there are headlamps on the floorhead to light the way in dark corners.

With nearly 50% off, the Shark Detect Clean & Empty Cordless with Auto-Empty System is at a new, lowest-ever price at Amazon. This is a slightly lower-specced, more affordable version of the Detect Pro, but still boasts a range of useful automation features, including the ability to intelligently increase suction when the floor is especially dusty. The auto-empty base is a major effort-saver and means no more messy bin emptying.

With 35% off, this powerful corded upright is at a new, lowest-ever price in the Amazon Big Deal days sale. This vacuum delivers powerful suction and boasts a host of automation features, including automatic suction adjustment based on dirt levels. The floorhead is specially designed to be able to suck up chunky debris when pulled backwards – a feature I found worked impressively well when I tested this vacuum.

With £112 off, the Stratos Cordless is at a new, lowest-ever price at Amazon. This is an older Shark line, but while it lacks fancy automation features, it's still a very capable cleaner, offering impressively strong suction. At under £200, it's a steal.

The Shark PowerPro is back down to its lowest-ever price in the Amazon Prime sale. It can auto-adjust suction based on floor type, and has a wand that can be released to flex forwards, making it much easier to clean under furniture. There's also up to 50 minutes of cleaning on a single charge.
