If you've got a quarter-acre lawn and you don't mind laying a boundary wire around it, the WR147 is a sensible pick. It's rated 0.25 acres (10,890 sq ft) and 35% (20°). The wire in the box is 590.5 ft. If the thought of pegging wire around every bed makes you groan, keep reading the other reviews.

If your yard is busy with toys and pets, we'd look at something else, because obstacle detection is a bump sensor. We're talking about the WR147, the 1/4-acre model. It's not the WR140 and it's not the WR155.

Makers usually publish one maximum slope and don't say whether it applies in the middle of your lawn or at the edge. When a model also gives a lower figure for the edge, that's the one to use there. If your bank runs into a bed or a fence, we'd leave some margin, because edges are usually harder.

What the wire changes

The WR147 doesn't need a sky view to know the edge, which is the point of the wire. It fails when the wire is cut, or when a bed moves and the wire stays put. The included length is 590.5 ft.

Honestly, this is the big one. It only knows something's there when it bumps into it. So if your kids leave toys on the lawn, the hose is out, or the dog likes napping in the sun, we'd look at a mower that can see what's ahead.

What owners report

Few owner reports for the WR147 turned up in the sources we read.

Running costs

Worx doesn't publish a subscription price for the WR147, so we can't tell you the yearly cost. The cost-to-own guide leaves it out of the yearly sum for that reason. Blade prices aren't published either.

Honest limits

If you don't want to lay and maintain a boundary wire, we'd skip it.
If your yard has toys and pets, obstacle detection is only a bump sensor.
If your banks are steeper than 35%, it's outside the rating.
If your lawn has heavy trees or two zones, size it from the size guide rather than the full rating.
If you need the side-passage width in writing, body width isn't published.

Support outlook

Worx doesn't have FCC Conditional Approval for new models, but models already authorized can keep getting updates until at least Jan 1, 2029. You can look up any model's FCC ID in the FCC equipment authorization search.

On Oct 13, 2026 the amazon.com listing showed unavailable, and the title still named the WR147.

Two other yards

If you want that quarter acre without a wire, the Navimow i210 AWD is rated 0.25 acres (10,890 sq ft) and 45%. Navimow i series review.

The RockNeo Q110H is the other quarter-acre comparison, rated 0.25 acres (10,890 sq ft) and 45%. RockNeo Q110H review.

Questions

Is the WR147 discontinued because the listing showed unavailable?

No. On Oct 13, 2026 the amazon.com title still named the WR147 and the listing showed unavailable. Stock can change, so the button stays.

Does it mow without a boundary wire?

No. It follows a boundary wire, so it won't mow without one. The manual lists 590.5 ft of wire included.

Will it see a pet before it bumps it?

No. The models page lists a bump sensor, so it won't see a pet before it bumps it. Obstacle detection is that bump sensor, not a camera or radar.
