iRobot Roomba Combo 10 Max + Auto Wash Dock Review

The Roomba Combo 10 Max + Auto Wash Dock can wash and dry its own mop pad, but it lags behind other high-end robot floor cleaners in vacuuming and scrubbing.

iRobot Roomba j9+ Review

The iRobot Roomba j9+ is a user-friendly robot vacuum that justifies its high price with strong suction power, reliable obstacle avoidance, self-emptying functionality, and ample app features.

iRobot Roomba Combo j9+ Review

The iRobot Roomba Combo j9+ is a versatile robot vacuum and mop with the ability to empty its own dustbin and refill its own water tank, but some competitors offer superior cleaning power and require less maintenance.

iRobot Roomba 694 Review

The Roomba 694 is iRobot's least expensive robot vacuum and an excellent budget-friendly floor cleaner that supports app and voice control, and lets you schedule cleaning runs.

iRobot Roomba Combo 10 Max review

Great for pet hair, not so much for mopping

Slim build ; Auto empty dock ; Unique mopping mechanism ; App is well-designed ; Cleans pet hair effectively

Suction power is limited ; Brush design pushes debris around ; Loud ; Slow ; Mopping isn’t very effective

The iRobot Roomba Combo 10 Max is smart, stylish and is great at vacuuming, but its mopping isn’t as effective as some other robot mops we’ve tested.

iRobot Cleaning Crew: Final Thoughts on Roomba 780, Scooba 230, Scooba 390 (Part 4 of 4)

I have to admit that I'm a victim of modern-day cynicism: In the beginning, I was certain that these three bots would be overpriced toys that could only do a negligible amount of cleaning, and I was almost positive they'd run into obstacles or other...

iRobot Cleaning Crew: Roomba 780 Robotic Vacuum (Part 1 of 4)

The thought of futuristic home care is pretty exciting. Nothing would impact our day-to-day lives more than having a clean, well-kept sanctuary, and if technology can let us have that with very minimal maintenance, that's a reason to cheer. Anyone…

iRobot 700 Series, Roomba 780 Review

It has been a few years since iRobot released new models of their prestigious Roomba series vacuum cleaning robots. Well 2011 not only brings one, but three different Roomba's in the all new 700 series. The Roomba 700 series was first announced late...

Improved battery life, bumper is softer on walls, touchpanel on 780 model is a neat feature even if it tags more on to the price, HEPA filter, remote control, and larger dirt bin. Between both the iAdapt and the Persistent Pass Cleaning Pattern...

Pricey and cleanup is still a bit time consuming especially if you have long hair

The Roomba 780 is a robotic workhorse. I really put it through its paces, to see if it overcame some of my past gripes I had with the Roomba 562. This newer generation seems like it floats on air around your home and it will get every piece of dirt –...

iRobot Roomba Combo 10 Max

Some smart features, but the iRobot Roomba Combo 10 Max is a frustrating product that's not quite powerful enough and it leaves floors wet.

Can move over carpets without wetting them ; Jobs make common tasks quick to start

Leaves floors (and robot) wet ; Suction power is behind other robots ; Confusing to use

A combination of the clever and the frustrating, the iRobot Roomba Combo 10 Max doesn’t quite cut it as a high-end robot vacuum cleaner and mop. Its camera-based navigation system, while good at avoiding common obstacles, is slow to map; the mopping...
