ONSON Robot Vacuum Cleaner,2 in 1 Robot Vacuum and

Most entertaining! I get a kick out of watching this robot do its thing. The cleaning job it does is incredible. At 78 years old, I finally arrived in the 21st century. It's working as I am writing this review. Talk about multitasking! I did one room yesterday and was amazed at how much debris it picked up. I now have complete confidence that I will no longer have dirty floors. After my initial cleaning, I am going to do a weekly regimen with my new "toy." I would definitely recommend thisRobot vacuum to anybody

It picks up very small dust particles not visible when you look at floor. I vacuum before using this robot and after vacuum from hardwood floor it picks up large amount of small dust that beyond any vacuum in market. I have 6pk vacuum and this one complements it.. I love it, thank you, it is life saver for me.

Strong suction, though it gets lost

We use this vac on tile and hardwood floors for crumbs, dust, dirt, and hair. It has strong suction, is userfriendly, and smart. Easy to clean with a convenient mount for storage. Even my teens prefer it over sweeping.

Super great vacuum

This is so great, light and easy vacuum cleaner for my car. picks up crumbs and any dirty trash well, which is a lifesaver for me as my son always likes to snack and something in the car, so I will use it for clean, so easily. also it has several attachments that are convenient to use in different parts of the car. So u can use it for anyway. And Its battery is very durable and lasts for a long time. Furthermore, it's very convenient to carry and requires very little space, so you can keep it in your car or at home. so it is perfect for my need, highly recommend !!

Light and Powerful cordless vacuum!

Great unit! Excellent powerful suction and the cordless battery is long lasting. Light unit, has all the attachments I needed. Great for the car and I also cleaned my stairs too. The lights are a great touch too for the dark areas *(like corners). Attachment is also great for under the sofa. Highly recommended!

Pleasantly Surprised

I have wanted an automated device to vacuum for a number of years. The recent Walmart sale on this device was too good to pass up. I am very pleasantly surprised with the efficiency and suction power of this guy. It worked hard and does a decent job.

Easy Daily Cleanup

I really like how easy this little vacuum makes cleaning. I can grab it anytime, no hassle, and it feels light in my hand. I use the attachments when I need to reach tricky spots, and the closer I get, the stronger it pulls. Super handy for everyday messes.

Doesn't meet my expectations

I looked forward to having this and I loved it when I tried it the first time in my room and kitchen. However, when I put it in my living room it suddenly like goes in reverse and gets itself stuck reversing into the wall, the zig zag or edges function won't work well there either. I don't understand it.

Total wastes of money won't work after couple days

Don't bother, I thought after reading all the good reviews it's safe for this purchase, but after a few usages, it wont even turn on more than 2min and turn off even those fully charged in charging station. And the remote was a joke wont even work after a few use. I'm so disappointed I want my refund back rather get a better brands than this.

FALSE ADVERTISING

I purchased the one that wasn't the cheapest so I could have the 2300pa power suction as stated on site. Received package and it states on box 1400pa!! Seriously?? False advertising DO NOT BUY!! Not to mention that the box looks like it was a return.
