These are the best last-minute Prime Day vacuum deals – trust me, I've tested dozens

Eufy Clean X8 Pro | Was $499, now $399 at Amazon
I just tested this robot vacuum and it's brilliant. With a mop function and detailed mapping capabilities. I think it's the best robot vacuum on the market, especially with $100 off the price.

LEVOIT IQ 40 Cordless Vacuum Pet | Was $239.99, now $179.99 at Amazon
Full disclosure: we weren't blown away by this vacuum when we put it to the test. However, it does the job, and it's best on carpets. A good choice for smaller homes, it has some handy extras like a flexible wand, telescopic crevice tool, dusting brush and motorised tool. However, if you've got mobility problems like arthritis, you should bear in mind that it's pretty top-heavy. 

Shark Vertex Cordless Vacuum | Was $399, now $199 at Walmart
I've tested vacuums for years, and this is still one of my favorites. After years of testing these I think it offers near-Dyson performance at a much more reasonable price, and now it's even less. My biggest bugbear is that the compact folding storage a bit of a gimmick (it actually takes up more room like this) but being able to bend at the neck makes it unbelievably easy to clean under furniture. 

Miele Triflex HX1 Plus Cordless Stick Vacuum Cleaner | Was $649, now $459.72 at Amazon
I've had a soft spot for this vacuum for years, and this gray colorway is currently the cheapest I've seen it. This vacuum has a great feature - you can shift the dustbin from the handle to the floor head for improved performance on carpet, and to make it easier to reach overhead. It's perhaps a little gimmicky, but when I tested it years ago I found that it genuinely helped. I wouldn't buy it if I lived in a house, but it's good for an apartment. 

Dyson V15 | Was $749.99, now $646.95 at Amazon
This is the best vacuum that we've tested. The green laser highlights dust that the naked eye can't see and it will give you numerical data on how well you've vacuumed. Amazon have taken almost $150 off, which is an unmissable offer. It's $80 cheaper than at Walmart, too.

Dyson Outsize + | Was $949.99, now $606.88 at Amazon
This is the best vacuum for pet hair bar none. It's lightweight, agile, and incredible effective on dirt and dander. Our biggest complaint with Dyson is the price, so any discount is worth buying.

Dyson Ball Animal 2 (Refurbished) | was $499.99, now $299 at Amazon
One of my favorite insider tips with Dyson is to grab a Ball Animal 2 around sales periods. Sure, it's an older vacuum and it's pretty clumsy, but if all you need is a powerful vacuum to totally transform your floors, this will do the job for hundreds of dollars less than a top-line Dyson. However, this isn't the lowest price I've seen this vacuum, and this model is refurbished. 

Samsung Bespoke Jet | Was $699.99, now $474.99 at Amazon
This vacuum is my favorite recommendation if you suffer from allergies, because it sucks dirt into a sealed bag on the charging base. It's neat, easy to use, and the Midnight Blue colorway lowest price this vacuum has been all year. A word of warning: don't feel tempted to update to the AI model: when we put it to the test, we found little new and no signs of 'artificial intelligence'. 

Dyson Omni-Glide | Was $349, now $299.99 at Walmart
If you have hard flooring throughout your home, it's worth considering the Dyson Omni-Glide. It's designed for hard floors only, and can move in any direction to suck up dust and crumbs. Walmart has the lowest price I've seen, $15 cheaper than anywhere else. However, on test we found that it shuts itself down if it detects carpet, so it's not for you if you have carpet or area rugs.  

Roomba Combo™ j7+ | Was $1099.99, now $799 on Amazon
The only thing we don't like about Roomba is the price, so it's great to see this model selling for $300 less. When the Roomba switches on, you can switch off: this little robot automatically empties its own bin for 60 days at a time. 

Shark Vacuum & Mop | Was $479.99, now $249.99 on Amazon
You can save more than $200 on this model, which is a vacuum and a mop in one. The Sonic Mopping function delivers 100 scrubs a minute for squeaky clean floors. To protect your rugs and carpets, you can set no-mop zones in the SharkClean app.
