Not Amazon, not Shark – this is the best place to buy a budget-friendly Shark robot vacuum cleaner this week

I've spotted a £450 discount on my favourite model!

Unless you’ve been living under a rock, you’ll probably know that it’s Amazon Prime Day this week. But as a Floorcare Editor who has covered these sales events for the past five years, I can tell you that Amazon isn’t the be-all and end-all of discounts. In fact, if you were looking to buy a Shark robot vacuum this week, I’d recommend shopping at Argos instead.

And right now, Argos is having a huge sale across its appliances, including the robot vacuum I’ve been using in my own home for the past few months - the Shark PowerDetect UV Reveal 2-in-1 Robot Vacuum & Mop (was £999.99, now £549.99 at Argos). Yes, that really is a £450 discount!

The beauty of the best robot vacuum cleaners (aside from their incredible ability to clean your house for you) is that they’re available at countless retailers across the UK - both online and in-store. And while Amazon and Shark are typically among the most obvious places to buy Shark robot vacuums, alternative retailers also slash prices year-round, including Argos and John Lewis.

Shark PowerDetect UV Reveal 2-in-1 Robot Vacuum & Mop: was £999.99 now £549.99 at Argos

Stock is moving quickly in light of this epic deal, but this robot vacuum is also price-matched at John Lewis if there's none left at Argos.

While I don’t claim to know everything (if only), it is quite literally my job to review robot vacuum cleaners. So, I’d like to think I know my hands-free appliances. And Shark's PowerDetect UV Reveal Robot Vacuum impressed me so much during testing that I had to give it an almost-perfect 4.5-star review.

One of the things I didn’t like, however, was the price tag, so the fact that it’s now on sale at Argos for almost half price is a major win in my book. Especially as the black colourway I have at home isn’t on sale for the Amazon Prime event, and it’s not on sale at Shark, either, as it’s completely sold out due to high demand.

However, it’s worth noting that the white colourway is on sale at Amazon for £489.99 if you’re looking for an even bigger discount. But as someone who has tested white robot vacuum cleaners before, I would always willingly lean towards black to try and hide the inevitable scuffs and marks that appear during cleaning. Both colourways are identical in perks and features, though.

The Shark PowerDetect UV Reveal has a runtime of 180 minutes, will also mop your floors while vacuuming, and comes with an auto-empty dock that can hold up to 1.51L of debris - making maintenance as minimal as possible.

As with all the best Shark vacuum cleaners, it’s also ridiculously easy to use and perfect for beginners who are buying their first robot vacuum. The pièce de résistance of this model, though, has to be the UV reveal technology, which uncovered so many hidden stains on my hard flooring (and left me feeling rather embarrassed).

But I wouldn’t be telling you to ditch Amazon and Shark for Argos on the basis of one robot vacuum cleaner deal, though.

That’s because Argos has also slashed the prices of other Shark robot vacuum cleaners, including the bargain Shark Matrix Plus 2-in-1 Cordless Robot Vacuum Cleaner & Mop (was £285.70, now £199.99 at Argos).

Alternatively, you could opt for the Shark ThermaCharged PowerDetect Robot Vacuum Cleaner (was £900, now £499.99 at Argos).

I haven’t tested either of them as there are simply too many robot vacuums and only one of me, so I would advise you to do your own research and read independent reviews.

Alternatively, you could snap up some Amazon Prime Day deals for other robot vacuum cleaners I have tested, which I’ve added below.

Will you be snapping up a robot vacuum this year? Now is the time to do it!
