Shark Clean & Empty Cordless Stick Vacuum

For most homes, yes. Even people who doubted the self-emptying dock on the Shark BU3523 end up relying on it: you drop the stick back after vacuuming and the bin is dealt with. The trade-off is space, since the dock takes up a patch of floor that a wall-mounted stick wouldn't.

Yes, for most. The Shark BU3523 is easy to move around, and people with limited mobility find it manageable for everyday cleaning. It isn't the lightest stick around, so anyone who needs to lift it overhead or carry it up several flights should keep that in mind.

A full floor or a mid-size home, for most. Shark rates the BU3523 at up to 40 minutes in ECO mode, and one charge typically gets a whole level done before it goes back on the dock. A very large house on high power may still need a recharge partway.

No. The BU3523 pulls pet hair out of carpets and rugs, and hair and strings don't wrap around the roller, so there's no cutting tangles free with scissors. For hair on sofas and stairs, the Motorized Hand Tool does the same job in handheld mode.

Not always. The floor head on the Shark BU3523 can tip up or feel loose, and when it loses contact with the floor it stops picking up properly. Some people press it back down with a foot. It's worth checking the head is seated firmly before each clean.

Partly. The Shark BU3523 goes fairly low but doesn't lie flat, so getting under low couches and beds is a squeeze. Taking the floor head off and using the wand on its own gets you further in. If your furniture sits close to the floor, that's the step to expect.
