The Shark Stratos Upright is good for bare floors. It easily clears away solid debris and pet hair on this surface type and does an excellent job of dealing with any material in cracks and crevices, like grout lines on a tile floor. It feels reasonably well-built and incurs fairly low recurring costs. Unfortunately, it's a heavy, bulky machine, and it can be a bit of a challenge to clean under some tables and chairs due to the bulky dustbin, so you'll probably have to make use of its 'Lift-Away' alternative configuration pretty often.
