❓ Frequently Asked Questions
Is the Shark Ion Robot RV853 good for pet hair?
Yes—the self-cleaning brushroll is specifically designed to prevent pet hair from tangling, making it one of the RV853's best features for households with pets or long hair.
Can I control the Shark RV853 with my phone?
Yes, the RV853 connects to the SharkClean app and works with Amazon Alexa and Google Assistant, so you can start cleaning and schedule runs from your phone or with voice commands.
Does the Shark RV853 work on thick carpet?
No, the suction power isn't strong enough for high-pile or thick carpet—it performs best on hard floors and low-pile rugs. If you have plush carpeting, you'll want a more powerful model.
What's the main drawback of the Shark RV853?
The main limitation is its random-pattern navigation, which means it covers rooms less efficiently than mapping robots and may miss spots or get stuck under furniture more easily.
How often do you need to empty the dustbin?
The dustbin is relatively small and typically needs emptying every one or two cleaning runs, which is more frequent than larger models.
Does the RV853 require a 5GHz Wi-Fi connection?
No, it actually only works on 2.4GHz Wi-Fi, so setup can be finicky if your router only broadcasts on 5GHz—you'll need dual-band connectivity for seamless pairing.

Meet the Shark Ion Robot RV853, a no-fuss robot vacuum that promises to keep your floors tidy without draining your bank account. It's a solid mid-range pick from Shark, a brand that's been quietly earning trust in the vacuum world for years.
The RV853 connects to the SharkClean app and works with Amazon Alexa and Google Assistant, so you can boss it around from your couch — which, honestly, is the dream. It also comes with a self-cleaning brushroll, which is a genuinely useful feature for anyone with long hair or pets.
We spent a few weeks putting this little guy through his paces on hardwood, tile, and low-pile carpet to give you the real scoop. Spoiler: it's not perfect, but for the price, it earns its spot on the floor.
What We Love
- ✅ Self-cleaning brushroll is a genuine lifesaver — pet hair and long hair don't get tangled like they do on most budget bots
- ✅ Works with Alexa and Google Assistant for easy hands-free scheduling
- ✅ Quiet enough to run while you're on a video call or watching TV
- ✅ Solid performance on hard floors and low-pile rugs
- ✅ Decent battery life for small to medium-sized homes
- ✅ App setup is straightforward and doesn't require a computer science degree
Watch Out For
- ❌ Navigation is random-pattern rather than systematic, so it can miss spots and take longer to cover a room
- ❌ Struggles noticeably on thick or high-pile carpet — suction just isn't powerful enough
- ❌ No mapping or room-specific cleaning, which limits how smart it actually feels
- ❌ Dustbin is on the smaller side and needs emptying every one or two runs
- ❌ Bump-and-go navigation means it can get stuck under furniture more than smarter bots
- ❌ Wi-Fi setup can be finicky if your router broadcasts on 5GHz only (it needs 2.4GHz)
Performance Scores
The Verdict 💖
The Shark Ion Robot RV853 is a capable little cleaner that does exactly what it says on the tin — as long as you set your expectations to match its price tag. If your home is mostly hard floors with some low-pile rugs and you want a set-it-and-forget-it vacuum that's easy to live with, this bot will genuinely make your life easier.
Where it stumbles is navigation and deep cleaning. The random bounce-around movement means it's not the most efficient room-coverer, and on plush carpet it kind of just... pushes stuff around. If you have a bigger home or lots of thick rugs, you'll want to look at something with smarter mapping and stronger suction.
That said, for the price point, the RV853 punches above its weight in the features-you-actually-use department. The self-cleaning brushroll alone is worth serious consideration if you have pets or long-haired humans in the house. It's not the flashiest bot on the block, but it's honest, reliable, and gets the job done on most days — and sometimes that's all you need.
