Problems, parts and running costs

Summary

iRobot’s first robot whose dock washes and dries its own mop pad, with a 3.4-inch body that clears low furniture and a pad that lifts onto the robot over carpet. Independent tests put its hardwood pickup and mopping behind cheaper machines.

Strengths

  • The mop pad parks on top of the robot and lifts clear of carpet; PCMag never had it wet a rug.
  • Tom’s Guide scored cleaning 95.5 and pet hair 97.5, with strong carpet pickup.
  • Obstacle avoidance is a genuine strength, and iRobot replaces the unit if it smears pet waste in the first year.
  • The 3.4-inch body clears low furniture and the front-opening dock fits under a shelf.
  • PCMag measured 116 minutes of battery, ahead of the Combo j9+ and the Ecovacs Deebot X2 Omni.
  • The dock dryer runs quietly, with no high-pitched frequencies in How-To Geek’s testing.

Weaknesses

  • PCMag measured hardwood pickup at 73.57% rice and 56.27% sand, behind the older Combo j9+.
  • Mopping leaves sticky residue and spreads debris; PCMag’s jelly test needed manual pad washes.
  • Without LiDAR, mapping is slow and navigation uncertain; How-To Geek returned it to the dock six days out of seven.
  • At 65-66 dB it is too loud to watch television through, and bin emptying cannot be paused.
  • The dock washes with unheated water and forced air, and PCMag found dirt clumps still embedded in the pad.
  • Owners report false “bin full” errors, charging and docking failures, and a dripping wet pad left overnight.

Full research notes and sources

There is no LiDAR turret. The robot uses a camera and an LED headlight, which keeps the body at 3.4 in but slows mapping and makes the machine less certain about where it is, according to Tom’s Guide, TechRadar and How-To Geek. PCMag’s first mapping attempt failed outright; its second took 32 minutes for a 1,500 sq ft two-bedroom apartment, against 39 minutes for the Combo j9+ and 10 minutes for the Ecovacs Deebot X2 Omni. iRobot claims its mapping is 7 times faster than previous iRobot technology, but the measured gap was about 1.2 times. The app has no real-time map position tracking.

Pickup is uneven. PCMag measured 94.10% of rice and 40.50% of sand on carpet, but only 73.57% of rice and 56.27% of sand on hardwood, where the older Combo j9+ collected 88.40% of rice. On 0.25 oz of jelly it removed all visible residue but left the floor sticky and carried seeds elsewhere. Tom’s Guide scored cleaning 95.5 and pet hair 97.5, yet found the brush flinging Cheerios off rugs into already-cleaned areas and measured 65-66 dB at six feet, too loud for television. TechAdvisor liked the carpet results but found sauce residue that needed hand mopping.

The AutoWash dock

The dock empties the bin into a bag for about 60 days, refills the 170 mL on-board tank, and washes and dries the microfiber pad. It uses unheated water and forced air, where competitors use hot water and hot air. PCMag found clumps of dirt still embedded in the pad after a wash and had to trigger pad washing manually several times during one mopping test. iRobot documents a multi-hour drying cycle and says the pad cannot be dried without being washed first. One owner reports the dock never gets the mop head dry, and How-To Geek found the robot abandoned overnight with a dripping wet pad on hardwood.

Owner reports and reliability

Owner threads and retailer reviews cluster on the same problems: false “bin full” errors two or three times a week, charging errors and failure to dock, a mop arm that stays extended, furniture collisions and job abandonment, debris flung rather than collected, and pet fur trapped in the recessed camera housing that triggers object alerts. Praise clusters on carpet and pet-hair pickup, the low body clearing furniture, and hands-free pad washing. iRobot publishes model-specific support articles for Error 36 dock-communication failures and for pad-wash and refill errors. No source gives a failure rate.

Is it worth it?

The robot launched at $1,399.99 and was later seen at $724.94 at Walmart, with street pricing reported at $999.99 by several outlets (Tech Advisor, 2026). Below about $750 the case rests on the AutoWash dock, iRobot’s app, obstacle avoidance and the carpet-safe pad; above $1,000 the measured deficits in hardwood pickup, scrubbing, noise and navigation reliability dominate. PCMag and How-To Geek both steered buyers to alternatives, and iRobot’s own page listed it as available at select retailers rather than direct. Confirm the warranty term and the price at the retailer before checkout.

Which model this is

This page covers the Roomba Combo 10 Max robot and AutoWash dock, item X085020, iRobot’s first dock that washes and dries the mop pad. It is not the Combo j9+ with its auto-fill but no pad washing, not the Combo j7+, and not the separate 705, 775 or 875 Combo models. iRobot publishes no suction figure, so ignore any numeric suction spec you see for this model.
