Yep, the Shark IX141 can work on both carpets and hard floors, which is pretty handy if you've got different types of flooring at home.
According to the manufacturer's description, it has a runtime of up to 40 minutes in standard power mode without any attachments. But just a heads up, the actual battery life might vary depending on how you're using it—like what power settings you choose and whether you're using any attachments.
From what we've found, folks have mixed experiences with the battery life. If you're cleaning both carpets and hard floors, many think the battery life is decent enough for a good-sized cleaning session.
Just remember, if you're doing a lot of deep cleaning on carpets, you might not hit that full 40 minutes since higher power settings take more battery. Some noted that after vacuuming large carpeted areas, including stairs, about half the battery was used up.
The 40-minute runtime is more of an ideal scenario, so it's worth thinking about your cleaning habits and needs. Since you can't swap out the battery on this model, it's a good idea to start with a full charge.
Breaking up your cleaning into parts might help, especially for bigger jobs, so you don't run out of juice in the middle.
Overall, the Shark IX141 does a solid job on both kinds of flooring. Just keep in mind that battery life can vary in real-world use, so a little planning can go a long way in making sure it fits your cleaning needs.
It's a good fit for many homes, but just remember to think about the battery when you're tackling larger cleaning tasks.
