Amazon Prime Day Deals: Up to 36% Off iRobot Roomba Robot Vacuums
Koupon.ai has verified amazon prime day deals across the Roomba range ahead of Prime Big Deal Days, led by the Roomba 105 Combo at $299 — 36% off its $469.99 list price, checked 25 September 2026. That model alone sold 3,000 units on Koupon last month. These amazon prime day deals cover the full line from a $32.99 refill bottle to the Max 775X flagship, and none of them needs a code.
Amazon prime day deals: Roomba combo vacuums by price:
Every Roomba on this list vacuums and mops in one pass. The real difference is the dock: the cheaper models empty by hand, the dearer ones empty themselves for weeks at a time. Decide how often you want to think about it — more in vacuum deals.
iRobot Roomba 105 Combo — $299, 36% off:
The value pick and the best seller here at 3,000 units last month, down from $469.99. Vacuum and mop with an auto-empty dock, which is the feature that actually changes the chore.
iRobot Roomba 105X Combo — $344, 27% off:
$344 from $469.99. The X adds the self-emptying base. Forty-five dollars more than the 105 above for a dock you empty monthly instead of weekly.
iRobot Roomba Max 775X Combo — $799.99, 20% off:
Down from $999.99. The top of the line — strongest suction, longest run time, and the dock does both debris and mop water.
iRobot Roomba 415X — $669.99, 16% off:
$669.99 from $799.99. A shallower cut than it carried earlier this week, so worth watching rather than buying today unless you want this exact model.
iRobot Roomba 705X — $1,269.99, 9% off:
Down from $1,399.99. The discount here was far deeper earlier in the week and has since rolled back, so this one is listed for completeness rather than as a buy. Worth a watch if you want the 705X specifically.
iRobot hard floor cleaning solution — $32.99, 41% off:
The deepest percentage on this page, down from $55.99, and the one consumable every Roomba mop owner reorders. 1,000 sold last month.
How to claim these amazon prime day deals:
No codes on the Roomba line — every price here is already marked down at Amazon. If you usually copy codes from our Amazon promo codes hub, this one takes a step fewer.
- Open the pair you want on Koupon.ai and tap Get deal on Amazon.
- Pick your size and colorway on the Amazon page — the discount is tied to the specific colorway, so check the price after you switch.
- Add to cart and check out. No code needed; the markdown is already applied.
🔹 Pro Tip: Roomba prices move inside the week, not just on the day. Two models on this page were several hundred dollars cheaper earlier in the week and have since rolled back, so check the number on the product page before you commit rather than trusting a figure you saw on Monday.
Which Roomba deal saves you the most:
On both percentage and sense, the 105 Combo at $299 is the answer — 36% off, self-emptying dock, and the model most people on Koupon actually bought. The Max 775X saves the most in dollars at $200 off, but you are still spending $799.99. The 705X and the 415X are both at shallow discounts right now; neither is a buy this week unless you want that specific machine.
Why watch these before 6 October:
Prime Big Deal Days opens 6 October. Robot vacuum deals are one of the categories where the discount moves several times inside the run-up rather than landing once on the day — the 705X has already been through a deep cut and back this week. Watching the model you want, rather than waiting for the event, is the play here. See what else is moving in trending home finds.
