Its vacuuming performance was also perfectly adequate for light soiling and the bagless dirt collector has ample volume for covering a large area – it's also really easy to remove and empty. If you do have pets or someone with long hair, it may struggle to pull all the hair out the carpet, though. Also, the overall suction power isn't great and relies overly on the brush to dislodge dirt. For instance when passing over the transition from a wooden floor to a tiled one, the raised door strip caused the navibot to miss the inch or so of dirt either side of it. More problematic, though, is how poorly the SR8855 copes with obstacles and edges.
Looking first at obstacles, the SR8855 seemed utterly incapable of actually detecting anything via its sensors. Even walls sometimes required a bump before it would respond to them. Combined with its bulk, this meant chair and table legs proved all too much and the navibot would invariably end up skirting round the whole lot. As for getting to the grime under sofas and coffee tables, you've got no chance.
This is bad enough but what really hurts the navibot is it doesn't do edge cleaning. Instead of detecting and tracking along the edge of a wall, it will just carry on in its own predetermined straight line until it hits a wall. When it does so it merely shimmies along and carries on in the same direction. So if it's approaching a wall at an angle you get a step effect. Combined with its limited ability to get into nooks and crannies, this leaves you needing to go round with another vacuum cleaner to finish the job.
So, if you have a large open-plan flat or house with few stairs (the navibot can detect stairs but it can't clean them) the SR8855 could be useful for getting the bulk of your cleaning done while you're out, leaving you to just whip round with a handheld vacuum cleaner when you get in. For any other living situation, though, the SR8855 just doesn't make sense. What's more, the latest Roomba is nearly half the price, though we're yet to test it (we have one in the office ready to be looked at soon) so it could yet prove to be completely useless.
The Samsung navibot SR8855 robot vacuum cleaner employs some clever tech and is a great way to get the bulk of your vacuuming done without lifting a finger. However, you'll still need a second vacuum cleaner to get in all the nooks and crannies and it is very expensive.
