The device works really well. The battery doesn’t last that long which is a bummer but the product does what it states. I hope I don’t have to replace the battery yearly. My floors are clean tho and I have a dog and cat and multiple surfaces, all of which it cleans well even with difficult door thresholds.

I’m happy with it

Size: L50 Hybrid-renewed, Size: L50 Hybrid-renewed

Works great. Edit: After a week that I wrote works great, it had the issue that when it starts cleaning it looses power and shuts off after it leave the dock. When it disengages from charging it’s dead basically so unfortunately I returned it. But I will buy it again I was happy with it.

Charging base makes awful high pitch noise.

Size: L50 Hybrid-renewed

It cleans fine but the charging base emits a terrible high pitch noise. I have to unplug it when nearby. Cats no longer want to sleep in the same room as the vacuum base. Update: A little over a year later and it appears the vacuum's onboard wifi module has passed the rainbow bridge to electric heaven. Can no longer connect the L50 to the app or local wifi. Tried resetting, reverting to older version of app, changing my wifi to 2ghz only. Trying setup in airplane mode. Nothing works.

It worked!

Set name: 10 Jumbo, Set name: 10 Jumbo

I bought this to fit a full size 4" memory foam mattress topper. I gotta say it took 3 of us. 1 to lay on the memory foam and 2 of us to get it shoved in and keep pulling the bag up. But it actually fit! My arm was dying using the hand pump so we used a vacuum. It worked better than the hand pump. Due to what I was storing it did not shrink very flat, but compared to the size of the memory foam it shrunk a lot and will definitely save space! The bags arrived today so I dont know how well it holds up long term but the bag was very sturdy yanking it up around the foam. Didn't tear or stretch. And it actually fit!

Air comes out and STAYS out!

Set name: 10 Medium

I’ve tried so many different versions of these vacuum storage bags over the years, and this company seems to have finally figured it out. They’re absolutely not exaggerating about the 80% space savings. What really impressed me is the pump design — it actually screws onto the bag, so it stays securely attached while removing the air instead of constantly slipping off. It also has a stop valve built in, which prevents air from escaping when you remove the pump to put the cap back on. Such a smart design improvement over other brands I’ve used. I bought the medium 10-pack to store my winter clothes in two 66-quart storage bins, and they fit surprisingly well. That said, part of me wishes I had also picked up a few of the smaller sizes just because they’d probably make stacking and organizing even easier. Overall though, I’m really impressed with the quality and design.
