Roomba 115X Combo robot vacuum is 57% off in Early Prime Big Deal offer – and it mops
Table of Contents
iRobot’s Roomba range isn’t what we’d call low-cost, but the sheer convenience means the robots can clean on autopilot, saving you precious time. Still, pricing is tricky, which is why we love the big discount Amazon has handed to one of the company’s more affordable models. An early Prime Big Deal offer means you can save a massive $270 – specifically on the Roomba 115X Combo Robot Vacuum and Mop. The $470 robot has dropped to $200, which represents a 57% discount on the popular model.

Why we’d pick the iRobot Roomba 115X Combo
Vacuums and mops in one pass
This time-saving gadget can vacuum and mop floors up to 900 sq ft of area on a single charge. It vacuums with 15,000 Pa (a high level of suction), then cleans with its mopping pad, which extends beyond the robot’s footprint. If you don’t want it to mop areas like rugs, you can set no-mop zones in the Roomba app. Then the Roomba will vacuum and mop (or not) as directed.
Self-empties for up to 90 days
You shouldn’t have to worry about emptying the Roomba’s AutoEmpty Dock for 90 days. So you can leave the Roomba to self-empty into it, and empty the dock around four times per year. The 2.5L AutoEmpty Dock also features an AllergenLock bag to keep, what iRobot says, is 99% of pollen and mold inside, without any dust cloud.

Excellent customization options
With the Roomba 115X Combo, you can customize every single run to provide the specific cleaning you need. You can choose one or two cleaning passes, pick from four suction levels, and choose from three mopping water or solution levels. Plus, you can direct the robot to target specific spills or messes without cleaning the whole house.
What to consider before you buy
The Roomba 115X Combo is the successor to the Roomba 105 and is a robot designed for small or medium houses. That’s worth noting, because this deal price is excellent for owners of those sorts of properties. If you have a larger property, this deal may not be for you, so you’ll need to invest in one of iRobot’s more range-heavy and expensive models.
