Roomba 205 DustCompactor Combo: Cool New Tech, But Otherwise Average

 

The iRobot Roomba 205 Combo vacuums well on multiple surfaces and minimizes maintenance by compacting dirt in its dustbin, but its battery life and mopping capabilities fall short of the competition.

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.

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 –...
