Which saves more time per week — a robot mower or robot pool cleaner?

A robot pool cleaner typically saves more time per week during pool season — 3 to 5 hours of manual brushing and vacuuming per week versus around 45 minutes of manual mowing for a 200 m² lawn. If you have both a garden and a pool, the pool robot delivers higher time-saving per pound spent.

Why is the Husqvarna Automower 315X increasing in resale value?

The Robot Resale Index shows the 315X up 2.4% year on year — one of the few robot categories not depreciating. Supply of used units with installed boundary wire is limited; the wire installation itself represents £300–£500 of added value that does not show up in the robot price alone. Buyers who want a working installation are willing to pay a premium over a new uninstalled unit.

Can I install the Husqvarna Automower boundary wire myself?

Yes, but it is significantly more complex than it appears. The wire must be laid at the correct depth (5–10 cm), with guide wires for the mower to navigate from charging station to lawn sections, and with loops around obstacles. An incorrectly laid wire will cause persistent navigation errors. Husqvarna's professional installation service provides a two-year warranty on the wire layout — worth it for anything above a simple rectangular garden.

How long does a Dolphin Nautilus CC Plus clean a pool?

The standard cycle is 2.5 hours for floor-only cleaning. The full cycle — floor, walls, and waterline — runs approximately 3.5 hours. For a pool up to 9 metres, this is sufficient for daily or every-other-day cleaning. The Nautilus CC Plus is rated for pools up to 12 metres on floor-only mode.

Which should you buy?

Choose Husqvarna Automower 315X

Choose the Husqvarna Automower 315X if lawn maintenance is your priority and you have a garden of up to 1,500 m². Note the boundary wire installation cost (£300–£500) if not already fitted — factor that into the total spend. Buy in November for the best seasonal pricing.

Choose Dolphin Nautilus CC Plus

Choose the Dolphin Nautilus CC Plus if you have a pool and currently spend 3–5 hours per week cleaning it manually. It is cheaper, requires no installation, and the £280–£380 used price delivers a 40–55% saving on retail. Buy in October when pools close for winter and supply peaks.

Bottom line

These are not true competitors — they automate different outdoor chores. If you need both and have the budget, the Dolphin makes the better first purchase because it requires no installation and starts delivering value on day one. The Automower 315X delivers more total time savings weekly but has higher setup cost.
