iRobot Roomba Plus 505X Combo Robot Vacuum & Mop

Amazon has the iRobot Roomba Plus 505X Combo Robot Vacuum & Mop at $480 — down from a regular price of $1,000, which works out to $520 off (52%). Combo robot vac-and-mop units at this performance tier typically sit above $600 even on sale, so this lands in territory where it's worth a serious look if you've been waiting for the price to make sense.

What you're getting: The iRobot Roomba Plus 505X Combo Robot Vacuum & Mop is a 2-in-1 unit that handles both vacuuming and mopping in a single pass — a feature set that usually commands a premium over vacuum-only Roombas. The "Plus" branding in iRobot's lineup typically indicates an auto-empty base is included, which means the dock handles debris disposal so you're not manually emptying after each run. It's designed for hard floors and low-to-medium pile carpet, and the combo functionality makes it most practical in homes that are predominantly hard surface with area rugs rather than wall-to-wall carpet. If you've been holding off on a combo robot because the price never justified it, $480 with an included base changes that math considerably.

Who this is for: Homeowners with open-plan kitchens and tile or hardwood throughout will get the most out of the vacuum-plus-mop combo — one robot handles sticky kitchen floors and the living room in sequence. Pet owners already familiar with the Roomba ecosystem who want to step up from a vacuum-only unit without buying a separate mop robot will find the upgrade cost reasonable here. It's also a practical fit for anyone with mobility limitations who wants to minimize how often they interact with the robot between runs — the auto-empty base earns its keep in that use case.

Worth it at this price? At $480, this is roughly what competing combo units from Roborock and Ecovacs cost at full retail — the S8 Pro Ultra from Roborock, for instance, runs $900-$1,100 new, while entry combo robots from Ecovacs start around $300 but lack auto-empty bases. The 52% discount is the headline, but the more meaningful number is that $480 for a combo robot with an included auto-empty dock is genuinely competitive with the broader market, not just a flattering comparison to its own inflated MSRP. That said: if you have mostly carpet and minimal hard floors, a vacuum-only Roomba in the $250-$350 range will serve you better — the mop pad adds no value on carpet.

Things to know before you buy: Amazon's standard return window is 30 days, which gives you enough time to run it through its paces on your floor types. Verify that the auto-empty base is included in the listing before checkout — iRobot sometimes sells the robot and base separately at different price points. No promo code is required at this price. Check whether your floor plan has narrow doorways or raised thresholds above roughly 0.7 inches, as most combo robots, including this one, can struggle with transitions that vacuum-only models handle more easily.
