iRobot Roomba Plus 515 Combo Review: A Compact Vacuum and Mop That Washes Its Own Pads
Strong suction, LiDAR mapping and a self-washing AutoWash Dock in a slimmer body, with a few smart-home integrations still unconfirmed.
The Roomba Plus 515 Combo pairs a 46% smaller chassis with 3x more suction than its predecessor, ClearView LiDAR mapping and an AutoWash Dock that hot-washes and dries its own mop pads while emptying the bin for up to three months at a time. It fits homes with a mix of carpet and hard floors that want a mostly hands-off routine without paying for the flagship tier, though it skips the automatic detergent dispenser of pricier siblings and several smart-home integrations beyond Alexa and Google Home are not yet documented. For a mid-tier combo that automates the two most tedious chores (emptying and mop cleaning) at a moderate price, it is a solid pick.
- Mixed hard floor and carpet homes

Who is the Roomba Plus 515 Combo for?
This is a mid-tier vacuum-and-mop combo aimed at buyers who want most of the hands-off convenience of iRobot's flagship models without the top-tier price. Its 46% slimmer, sleeker body compared to the previous Plus 505 generation is built to fit under more furniture, while ClearView LiDAR navigation and PerfectEdge extending brushes target daily debris, pet hair and edge/corner dust in homes with both carpet and hard flooring.
What the Roomba Plus 515 Combo offers
Suction is rated at 22,000Pa, roughly 3x stronger than the previous Plus 505 generation, paired with a rubber-and-bristle brush combo for mixed debris and pet hair. DualClean spinning mop pads add 2x deeper scrubbing pressure for dried-on messes, and the pads automatically lift when the robot detects carpet so rugs stay dry. The AutoWash Dock does the maintenance: it self-empties the bin for up to three months, hot-washes the mop pads at 167°F and hot-air dries them at 113°F, and the robot auto-recharges on its own. Navigation covers obstacle detection, cliff detection, multi-room mapping, no-go zones and real-time progress tracking, all managed through the Roomba Home App with scheduling and voice control via Alexa or Google Assistant.
What to know before you buy
Unlike iRobot's higher-tier Combo models, the AutoWash Dock on this unit refills and empties water automatically but does not auto-dispense cleaning solution, so adding a compatible detergent to the tank is a manual step. Wi-Fi is 2.4GHz only, with no 5GHz band, and Bluetooth support is not documented. Apple HomeKit, Samsung SmartThings, Home Assistant and Matter compatibility are also not confirmed for this specific model at launch, so buyers anchored to those platforms should verify before purchasing. A handful of specs, including onboard dustbin capacity, dock bin capacity, noise level and charging time, have not been published yet.
Is the Roomba Plus 515 Combo worth it?
For a household that wants strong suction, self-washing mop pads and a dock that empties itself for months at a stretch, without stepping up to iRobot's most expensive tier, the Plus 515 Combo covers the essentials well. The trade-offs are a manual detergent step and a handful of smart-home integrations that are not yet confirmed. Buyers who mainly need Alexa or Google Assistant voice control and a genuinely low-maintenance vacuum-and-mop routine are the best fit; those who need automatic detergent dispensing or guaranteed Matter/HomeKit support may prefer a higher-tier sibling.
Frequently asked questions
How long does the Roomba Plus 515 Combo run on a single charge?
It is rated for up to 295 minutes of cleaning per charge, covering up to 2,000 square feet, before auto-recharging at the AutoWash Dock.
Does the AutoWash Dock add cleaning solution automatically?
No. The dock auto-refills and empties water and auto-empties the bin for up to 3 months, but adding a compatible cleaning solution to the tank is a manual step on this model.
Will the mop pads get my carpet wet?
No. The robot automatically detects carpet and lifts the mop pads before crossing onto it, so it can vacuum-only across rugs without wetting them.
Does it work with Alexa and Google Home?
Yes, voice control works with Alexa and Google Assistant-enabled devices, plus scheduling and control through the Roomba Home App.
Does it support Matter or Apple HomeKit?
That is not confirmed for this specific model at this time. Buyers who rely on Matter, Apple Home, Samsung SmartThings or Home Assistant should verify current compatibility before purchasing.
