3 Months of Real Use — Across Three Units
The Roomba Max 705X Combo is iRobot's first attempt at a mopping robot with a roller mop. There was a lot of hype around this when it first released — it was iRobot's most advanced 2-in-1 to date on paper, with a new PowerSpin Roller Mop, an extending mop, a roller mop cover that physically retracts during vacuuming, and the same Clear View front sensor that scored so well on the 705 vacuum-only. The hype didn't survive the unboxing. I ended up buying three of these robots to complete the test — the first two had hardware issues that required returns, and the third only ran after iRobot's quiet fix campaign finally caught up to my serial number.
The Naming Note Worth Mentioning
iRobot put the 705 name on more than one robot, which is confusing if you're shopping. There is a vacuum-only Roomba Max 705, which I reviewed separately, and there is this combo, which sells under both a plain 705 Combo model number and this 705X Combo model number. Same Clear View sensor and same dual brush rollers across the family; different docks and different mopping hardware between the vacuum-only and the combos. If you want mopping, make sure you are looking at a Combo. If you just want vacuuming, the plain Max 705 is the one.
Three Units. Two Returns. One Fix Campaign.
When I first got my unit, setup was extremely hard and frustrating. The app was a new app Roomba had just released for the new-generation robots, and as soon as the robot was unboxed it tried to do an update — it took all day, I couldn't get it done, I had to let it sit overnight. Not sure what really happened. What I do know happened is I sent the unit back because when I started using it, the dock started leaking water right away. I spent a ton of time trying to figure it out and never really did figure it out, so I sent the unit back.
Then I did a video. Then Roomba contacted me and said I had a bad unit and just needed to let the software update in the dock, which is an extremely slow process. During that phone call I gathered — I'm just guessing — but I gathered that they knew this problem existed with the dock leaking water and they knew they needed to do an update on it, and they were still delivering them in the update process. It's extremely slow and frustrating and can lead people to thinking the robots are bad. After 4 or 5 months they finally came out with a fix. They contacted people through email. I think it should have been more widespread. They delivered two free gaskets that you had to put in the dock and it did seem to help the problem with leaking.
I sent the first two units back for various reasons, and finally got a third one that was good and installed the gaskets and the dock was updated.
What Works
The Clear View Front Sensor
Shared with the vacuum-only Roomba Max 705 and the strongest part of the entire 705 platform. Scored 8/10 on the obstacle test — identifies cables, toys, and pet waste. After one identification it remembers the obstacle location for the rest of the run. The app flags identified obstacles on the map with a marker.
The PowerSpin Roller Mop
When the dock works, the mop works. The PowerSpin Roller Mop continuously self-cleans during the run, extends to the wall, and uses a retractable mop cover that physically protects carpets from getting wet during vacuuming. This is a real engineering investment and the part of the robot I think iRobot got most right.
Maintenance Access
Dust bag swap is clean with spare-bag storage in the dock. The dual brush design has end caps designed to release wrapped hair — they do work for that, though not perfectly.
What Doesn't Work
Dock Quality Issues
The first-wave units shipped with a dock-leak problem that iRobot eventually addressed through a free gasket and dock firmware update mailed to affected customers. iRobot didn't make this a widespread or public-facing fix campaign — I think it should have been more widespread. If you buy this robot today, you want to confirm your unit's dock is the post-fix revision before you accept delivery.
The App Is Hard To Use
This robot is just extremely hard to use, the app is not feature-rich, and it's hard to customize for your home. Even this second-generation app is slow. Sometimes you can't read certain things when it's on an iPad or your phone. Certain features are hidden by how it's built. Sometimes I'll have to go to a different phone or computer or tablet to see everything, which leads me back to the features and the format and how it works — just kind of not really done very well. There's already a proven ecosystem out there for robot vacuum cleaners and I feel like Roomba has just come up with their own way of thinking. Roomba's way of thinking is that they want you to automate it. They want quick buttons like clean after supper, clean in the morning. I don't think we're quite there yet. Maybe we will be, but right now we need to interface with these robots a lot better and fine-tune them for the home.
Dust-Bag Indicator Issue
When I've been using it in the basement testing it to failure, the dock dust-bag red light comes on randomly. I can't figure out why the light is on — the dust bags are installed all the way and I reset the dust bag reminder. Just some things that make this robot feel like a first-generation product from Roomba.
Navigation And Hair Wrap
I found the navigation just to be off — sometimes it would not clean an area, then go back to the dock. The dual brushes are an older design for vacuuming. They do get quite a bit of hair wrap on them; Roomba really hasn't addressed hair wrap. No corner reach with the spinning side brush, but the mop does go off to the side. The robot is tall and very heavy. It's loud when it's actually vacuuming and mopping.
The Pricing
This was very expensive at launch, and the model naming across the 705 family adds to the confusion at the shelf. iRobot has been discounting this robot substantially, which suggests the market has spoken on the launch pricing.
Roomba Max 705X Combo vs the Competition
Roomba Max 705X Combo vs Mova P10 Pro Ultra
The comparison that anchors my Skip It verdict across the entire Roomba lineup this season. At roughly half the Max 705X Combo's MSRP, the Mova P10 Pro Ultra delivers a more complete combo experience without the launch quality issues — and the dock has worked out of the box on every unit I've tested.
Roomba Max 705X Combo vs Roborock Qrevo Curv
Under MSRP with significantly superior technology — split-brush hair handling, a more capable app, and a dock that hasn't required a fix campaign. The split-brush design alone solves the hair-wrap complaint that's persistent across the Roomba lineup.
Roomba Max 705X Combo vs Roomba Plus 505 Combo
Inside iRobot's own lineup, the cheaper Plus 505 Combo uses spinning pads instead of the Roller Mop, with PrecisionVision AI obstacle avoidance instead of Clear View. The 505 didn't go through the same launch quality issues — if you're committed to a Roomba combo and you can accept spinning pads over a roller, the 505 is the lower-risk pick.
Roomba Max 705X Combo vs Roomba Max 705 (vacuum-only sibling)
The vacuum-only Roomba Max 705X scored notably higher in my testing (6.4/10 vs 5.2/10 for this Combo) because the dock complications and launch quality issues don't apply to the AutoEmpty-only dock. Same Clear View sensor. Same dual-brush vacuum hardware. If mopping isn't a requirement for your home, the vacuum-only sibling is the smarter pick from this family.
