Great cordless vacuum!
I am very happy with my recent purchase! It's incredibly light and easy to use. I particularly appreciate how it automatically adjusts its power based on whether I'm cleaning a floor or carpet. What I love most is the stand station. It's so convenient not having to fix it to the wall, and the auto-cleaning feature is a fantastic bonus. Beyond these features, the 5-year warranty speaks volumes about the quality of this product. I absolutely recommend it!

Love this lightweight work beast!
I have spinal stenosis and several health issues and I’m unable to lift a heavy objects. I use a cane to get around. My niece has this vacuum and recommended it as her husband is quadriplegic in a wheelchair with limited mobility in his hands/arms. It’s perfect for me because it’s lightweight. My husband does the heavy duty cleaning and I help with the lighter easy to reach items. This vacuum suctioned very well, automatically switching from bare floors to carpet without changing a thing. With it being cordless which was a must have on our list my Husband says it’s great for cleaning the stairs. Battery life so far has been awesome! We are able to clean an 1800 sq ft house and still have battery time to spare. We have one small dog and seem to accumulate dust bunnies often, which drives me crazy. This vacuum is so handy we are able to stay ahead of it all. It maneuvers well but my husband said it’s a little tight getting under low pieces of furniture with the beater head on, which it is easy to remove and just use the pipe hose to reach under furniture and beds. Love everything about it except the beater plate wants to pop back up in standing position when I’m vacuuming too close to where my feet are. But, I figured out how close I can come without it doing that. But other than that, this thing is impressive! I woukd definitely recommend this to anyone, especially if you have mobility issues. Very lightweight and yet it’s a work beast!
