iRobot Roomba 694 Robot Vacuum Review (2026)

Where the 694 makes sense

In a studio or one-bedroom apartment, a robot vacuum's job is boring consistency: run daily, keep floors visibly clean, dock reliably, survive pet hair. That is exactly the 694's profile. The dock is small enough to hide under a console, the robot handles the hard-floor-plus-low-rug mix typical of rentals, and iRobot's parts ecosystem means brushes, filters, and batteries stay purchasable for years - a real longevity advantage over no-name brands that disappear.

Cleaning performance, especially pet hair

The 694 uses dual counter-rotating rubber-and-bristle brushes plus an edge brush, and its standout behavior is Dirt Detect: an acoustic sensor that notices concentrated debris and makes extra passes over it. Owner feedback consistently rates its pet-hair pickup above its price class - the dual-brush design tangles less than single-brush budget rivals, though long human hair still needs an occasional scissors session. On bare floors and low-pile rugs it does its best work; high-pile carpet is a stretch for any robot in this bracket.

The navigation trade-off

This is the deciding factor. The 694 navigates semi-randomly - it bounces, follows walls, and statistically covers a small space well, but it does not map your home, cannot clean a specific room on command, and in larger or furniture-dense spaces will miss patches on any single run. Under roughly 700 sq ft, daily randomized runs converge on full coverage and the limitation barely shows. If your space is bigger, or you want room-by-room control and no-go zones, spend up on a LiDAR mapping robot like the eufy L60 or Roborock Q5+.

Living with it: bin, noise, and app

There is no self-empty dock at this price, and the onboard bin is small - with a shedding pet expect to empty it every one or two runs, a 10-second job. Noise is a steady mid-range hum, fine to run while out, distracting on a video call. The iRobot app covers scheduling, and Alexa or Google voice commands work for start/stop. Maintenance is the usual robot routine: empty bin, de-hair the brushes weekly, replace filter and edge brush every couple of months.

Verdict: should you buy it?

For apartments under ~700 sq ft, yes - it is the most dependable robot vacuum in its price range, and the brand's parts availability makes it a keeper rather than a disposable gadget. For larger homes, mapping robots at $300-400 are a better fit. If daily hands-off maintenance matters more than deep cleaning, the 694 delivers exactly what it promises.
