Expert Reviews


What reviewers liked

The motorized brushroll uses helix-pattern, high tensile bristles that will provide adequate agitation on bare floor and carpet.
The Shark actually did quite a good job of driving around the furnished room, failing to get stuck in any of our three separate trials.
You can begin a cleaning by pressing the giant clean button on the app’s home screen or set dates and times for them to start automatically.
The Shark Ion Robot 750 cleans obvious messes just fine, and its app offers the kind of control everyone wants from their "home of the future."
We found the device had no problem travelling over rugs and floor thresholds and even managed to avoid some tricky cable hazards.
The Shark is pretty quiet and easy to use; it the simplest of the bots I’ve had to navigate.
- Wired
It detected furniture and other obstacles quickly and avoided contact. It is a quiet bot. It has a slim desgin, and is able to maneuver under the furniture.
Cleans, docks and recharges with minimal effort on your part. Turning machine on and off, and scheduling it to run, can be performed through your smartphone or Alexa. Avoids stairs and other obstacles. Slows down around baseboards and furniture to avoid scratching. Lasts up to 70 minutes before needing recharging. Finds recharging station by itself as battery gets low. Users love that the machine sucks up dirt without scratching hardwood floors. Easy to empty bin. Picks up everything from small specks of dirt to large messes like spilled Cheerios.

What reviewers didn't like

But since this robot does not have a strong motor that an upright vacuum uses, don’t expect it to deep clean carpet.
This robot isn't a great value pick, performing almost the same as less expensive models.
Each cleaning cycle of my downstairs space took around an hour.
The Shark robot vacuum is less efficient with smaller particles such as sawdust and flour.
However, we did notice a worrying tendency — the robot ploughed enthusiastically into table legs, sofas and chairs without cause or care.
Its performance on hardwood and carpet was also a little disappointing.
- Wired
The bot dragged our test pet hair around the carpet which lowered its overall carpet score. Its edge performance lacked a bit on our test surfaces because it didn't get close enough to the corners and walls.
No remote so you must be somewhat tech saavy. Doesn't work great on thick carpets.
