In just 24 hours of Prime Day, Amazon has seen a whirlwind of deals especially for home tech. If you’re looking for a robot vacuum that also mops and doesn’t break the bank, the search can be tough as most models still hover around $500 or more. That’s what makes today’s deal on the iRobot Roomba Robot Vacuum and Mop Combo (Y0140 mode) so impressive: The price has dropped yet again this morning and now sits at $139, a 49% discount from its usual $274. This is the lowest price ever for this model, and as Amazon’s best-seller in its category, it’s moving fast. See at Amazon Cheapest (and Good) Vacuum and Mop This Y0140 robot vacuum and mop has a strong 4-stage cleaning system that vacuums and mops all in one pass with dust and dirt not getting left behind. The unique edge-cleaning brush is ideal for edges and around walls so your whole floor gets done. With its intelligent navigation, the Roomba moves methodically in neat rows and uses sensors to avoid bumping into furniture or falling down stairs. What’s great is that it’s ready to go straight from the box and it takes mere minutes to install. iRobot Home App offers even more convenience and lets you schedule cleanings, see cleaning reports and even activate “Clean While I’m Away” mode so that your floors are spotless when you come home. You’ll always know exactly where your Roomba’s cleaned with full maps and cleaning reports in the app. The compact design is great for easily tucking the Roomba under sofas and beds and other low-standing furniture where dust is likely to build up. The brush that sweeps along edges assures that the toughest areas are never left behind. With up to 120 minutes of cleaning time on one charge, the robot goes far and far before it automatically goes back to its charging station. The built-in mop uses a micro pump to keep the cleaning pad perpetually saturated with an even amount of water and the microfiber pad can be washed as many as 30 times. You have three levels of water to select from so the mop works well on a variety of flooring types and spills. For spots that need to be treated specially, spot cleaning mode enables the Roomba to stay in a single location for up to two minutes. One last thing: don’t wait too long because at this price, it’s likely to sell out fast. See at Amazon
