iRobot Roomba 705X Combo Review: A PowerSpin Roller Mop and 75 Days of Hands-Off Emptying

LiDAR navigation with AI obstacle avoidance, a self-washing roller mop and an AutoWash dock, plus rare Siri and HomeKit support.

The verdict

The Roomba 705X Combo is iRobot's answer to the roller-mop generation: a PowerSpin roller spinning at 200 RPM that scrubs rather than wipes, washed with heated water in the AutoWash dock and dried with hot air, with cleaning solution dispensed automatically. The dock also empties the robot for up to 75 days at a time, which is the longest interval in common use. Navigation is LiDAR with PrecisionVision AI obstacle avoidance, multi-room maps and no-go zones, and battery life is 180 minutes. Notably for a robot vacuum, it supports Apple HomeKit with Siri voice control alongside Google Home and Alexa.

Best for
  • Apple households wanting Siri control
  • Hard floors with rugs
  • Long gaps between maintenance
  • Homes with obstacles and pets

Pros

  • PowerSpin roller mop at 200 RPM, washed with heated water and dried with hot air
  • Automatic cleaning solution dispensing
  • AutoWash dock empties the robot for up to 75 days
  • Apple HomeKit with Siri, plus Google Home and Alexa
  • LiDAR navigation with PrecisionVision AI obstacle avoidance, multi-room maps and no-go zones
  • Automatic Carpet Boost and an edge-sweeping brush
  • Roller lifts under a carpet cover so rugs stay dry
  • 180 minute battery with auto-recharge

Cons

  • Suction power is not published, so it cannot be compared on Pa
  • Water tank, dustbin capacities, charging time and noise level are not documented
  • No SmartThings or Matter support, and Home Assistant is undocumented
  • 2.4 GHz Wi-Fi only
  • Large dock that needs a permanent space
  • Ongoing consumable costs, and warranty terms are not documented

Who is the Roomba 705X for?

It fits a household that wants to interact with the robot as little as possible. Emptying up to 75 days means the dock bag becomes a seasonal chore rather than a weekly one, and because the roller mop is washed and dried automatically with cleaning solution added for you, the mopping side has no routine either. The Apple HomeKit and Siri support is worth flagging separately: most robot vacuums skip Apple entirely, so for an iPhone-centric home this is one of the few that answers to Siri as well as to Alexa and Google Home.

What it does well

The PowerSpin roller mop is the significant upgrade over pad-based systems, spinning at 200 RPM so it scrubs the floor with continuously washed fabric, and it lifts under a carpet cover so rugs stay dry. Navigation covers the full set: LiDAR mapping across multiple rooms, PrecisionVision AI obstacle avoidance for cables, shoes and pet messes, cliff detection and user-defined no-go zones. Automatic Carpet Boost raises suction on carpet, and an edge-sweeping brush pulls debris out of corners. The app provides real-time tracking and scheduling, and the robot recharges itself between runs.

What to know before you buy

Suction is not published as a Pa figure for this model, which makes direct comparison with rivals quoting five-digit numbers impossible, so judge it on iRobot's carpet boost behaviour rather than a specification. Several other figures are also undocumented: water tank capacity, dustbin capacities, charging time, noise level and warranty terms. SmartThings and Matter are unsupported, and Home Assistant compatibility is not documented. Wi-Fi is 2.4 GHz only. Consumables for a roller mop and an emptying dock are an ongoing cost, and the AutoWash dock is a large piece of furniture that needs a permanent home.

Is the Roomba 705X worth it?

It sits in the premium bracket and earns it on convenience rather than raw numbers: the roller mop, the washing and drying dock and the 75 day emptying interval genuinely reduce how often you think about cleaning. Apple support is the differentiator against rivals with bigger suction figures. If you compare purely on published Pa, this model gives you nothing to compare with, so the decision comes down to trusting iRobot's navigation and the automation of the dock over a spec-sheet contest.

Frequently asked questions

Does the Roomba 705X work with Siri?

Yes. It supports Apple HomeKit with Siri voice control, which is unusual for a robot vacuum, alongside Google Home and Alexa.

How often do I need to empty it?

The AutoWash dock holds up to 75 days of debris, so emptying becomes an occasional task rather than a weekly one.

How does the mopping work?

A PowerSpin roller spins at 200 RPM to scrub the floor, and the dock washes it with heated water, dries it with hot air and dispenses cleaning solution automatically.

Will it wet my carpets?

No. The roller mop lifts under a carpet cover when the robot moves onto carpet, and Automatic Carpet Boost raises suction at the same time.

How much suction does it have?

iRobot does not publish a Pa figure for this model, so it cannot be compared numerically with robots that do.
