The 3 best October Prime Day robot vacuum deals, according to a professional reviewer

LIVE BLOG: Get the latest news on October Prime Day 2024

If you think deciding which robot vacuum to buy is hard to buy at any random point in the year, the decision fatigue ramps up significantly during a big sale event like Prime Day. Think about it: All the robovacs you've been considering are now cheaper and less daunting of an investment, and a few other models that may have been too expensive before are suddenly in your price range.

But considering my actual (and very normal) adult job is to test robot vacuums in my own home and then narrow those options down into recommendations for people, my mind subconsciously begins to pull out the two or three best of the best robot vacuum deals during Prime Day to have a concise list at the ready for when a friend or family member inevitably asks me which robot vacuum they should buy.

And as Mashable's resident robot vacuum expert, I'll drop those Prime Big Deal Days suggestions for you here, too. I know everyone is shopping based on different cleaning needs and priorities, so I'll give you three options that vary based on price and things they can do — and yes, I've tested all three in my own apartment.

Best October Prime Day premium robot vacuum deal

Why I like it

This one's my pick for anyone who prioritizes the most meticulous, hands-off cleaning possible and is willing to pay the big bucks for it.

Of the handful of robot vacuums that retail for well over $1,000, most are on sale this Prime Big Deal Days — but the Roborock Qrevo Master stands out to me as the best bang for your buck. Compared to the $1,799.99 Roborock S8 MaxV Ultra that I've also tested (which isn't on sale for Prime Day), the Qrevo Master dishes out the same 10,000 Pa suction power (both of which were as thorough as you could ask from a robot vacuum on my cat hair-covered rugs), washes and dries its own mopping pads, and even has the same pet camera that can livestream whatever the robot vacuum sees as it's cleaning (and even go searching for your pet).

But the main thing that set these two models apart for me was the mopping pad mechanism on each. The Qrevo Master scrubs with two pressurized, spinning mopping pads rather than the large, flat mopping pad of the S8 MaxV Ultra. More importantly, one of those spinning pads can extend out from under the vacuum and reach into corners, reaching several inches further into right angles and detailing walls better than most other hybrid models. (The Qrevo Master also does this with dry vacuuming.) Watching this unfold in the tricky overhang of my kitchen cabinets immediately sold me.

Best October Prime Day self-washing and drying deal (on a budget)

Why I like it

My number one robot vacuum deal pick from Prime Day in July is back, just with an even better discount this time (by $50). I dubbed the Eufy X10 Pro Omni as the most surprising robot vacuum I've tested all year because it offers the most premium feature in the 2-in-1 robot vacuum market right now — self-washing and drying mopping pads — for hundreds and hundreds of dollars less than many flagship models from other brands. To me, not having to manually attach, detach, and wash the mopping pads every time the vacuum mops is the line between a hybrid robot vac being worth it or not — because I definitely won't use the mopping feature as often as I want to if it makes extra work for me, too.

Best October Prime Day Roomba deal

Why I like it

I couldn't not make a Roomba recommendation — I know some of you want that Roomba street cred.

While I am pleasantly surprised that the Roomba Combo 10 Max is on sale for Prime Day despite not even being out for six months, I still can't say that it's the best Roomba deal overall. The Eufy model I've recommended above (among several other options) simply does all of that self-washing and drying for much cheaper.

What's far more impressive is the 50% discount on the tried and true Roomba j7+. If your home doesn't have enough hard floors to make mopping a crucial feature, this is absolutely your best bet. It still empties itself, so you won't have to deal with the dust bin for weeks at a time. But its real standout feature compared to any other self-emptiers in the $400 price range is its small obstacle avoidance technology. This is what allows a robot vacuum to scope out obstacles less than three inches tall that would usually cause a problem if they were to be sucked up, like phone chargers, pet waste, or pieces of laundry. It's a rare feature to see in this price range at all, and iRobot's is the most accurate version of it that I've ever experienced.

For more details on its cleaning capabilities, read my full review of the Roomba Combo j7+ (and ignore the parts about mopping, because the j7+ on sale here is just the non-mopping version).
