The two jobs
A cordless push mower here collects. You walk, and the clippings go into a box you empty. The example is the 136e Kit: hand-propelled, 34 cm, 35 L bag, two 2 Ah batteries, about £199, 4.4 from 264 reviews, stated area up to 300 m². The 132e at about £179, with a 30 L box, is the same walk-and-collect job with a thinner listing. It is not a second method.
A robot, where the listing mentions clippings, mulches little and often. The example is the A 6v at about £949, with no reviews. You are trusting a map in STIGA.GO and a base you still have to site. The A 4 does not state a clippings method. Do not call it a mulcher because the A 6v says daily mulching.
What you pay in this comparison
Collectors stay under £200. The first robots are about £949 and about £999, and the set then climbs past £1,000. You are not choosing a slightly dearer battery. You are choosing a tool you pick up or a system you install.
A 200 m² lawn does not require a 1,500 m² robot. The 136e’s stated area is already 300 m², with the caveat that owners often needed another charge. The area ladder is on the Stiga lawn mower buying guide. The 136e has 264 reviews. Six ASINs have none. No stars on the A 6v means about £949 is a specification decision, including a base the listing does not confirm.
When the cordless mower is the better tool
Choose the collector if you will walk and you want a box. A small flat lawn, a tight budget, and grass that sometimes waits a fortnight all point that way. A collector can take a longer sward into the bag until the bag fills or the battery fades, which 136e reviews already report.
Choose it if a charging base has nowhere to live. Several robot listings do not confirm the base is in the box, and a base wants outdoor power, not a lead across a wet path. No outdoor socket is a stop. Skip the collector if the bank is the problem: neither push model prints a slope.
When the robot is the better tool
Choose the robot if you will not walk, and you can site a base under open sky on a lawn inside a stated area. The 136e only cuts when you are there. The A 6v is sold to run from a schedule. The condition belongs in the same sentence: the robot is the better tool if the lawn is inside the ceiling, the grass stays short, and the base and the socket are real. It is the worse tool if those are hopes.
The listing does not confirm the base on the A 6v. STIGA’s A 6v page tells you to place a base and says there is no antenna. That is the maker’s picture, not a packing list for B0GMRG221S. Read how to set up a Stiga robot mower before you treat “no boundary wire” as “nothing to install”.
Common questions
Is a robot worth it if mowing takes twenty minutes?
It is worth it if you want those twenty minutes back every week and you will site the base properly. It is poor value if the lawn is small and about £949 is several times the 136e. Twenty minutes that then needs a second battery, as some 136e reviews describe, is a different sum. Count the season, not one dry Saturday.
Which one collects the grass?
The collectors do. The 136e uses a 35 L hybrid bag. The 132e uses a 30 L box. Robots that mention clippings here say daily mulching, so the grass stays on the lawn in short pieces. The A 4 does not say which it does. If a box is the point, you are in the push half.
Which one needs an outdoor socket?
A robot base does, once you have a base. Several ASINs do not confirm the base in the listing, which does not remove the need for power if it arrives. The collectors charge packs indoors. An outdoor socket that does not exist yet is an electrician’s job, not a weekend adapter.
Can a robot handle grass I left for a fortnight?
Treat long grass as the collector’s problem. Daily mulching is for a lawn cut often. Wet growth left for a fortnight is where push-mower reviews mention stalling, and a robot sold to nibble daily is the wrong restart. Cut it back before you ask a mulching robot to recover it.
How much more is the robot in this set?
From the 136e at about £199 to the A 6v at about £949 is £750 on these amazon.co.uk prices. The A 4 is about £999. Larger ceilings go up to about £1,466.38. None of those robot prices confirms a charging base in the box. The collector prices do include the batteries the titles and bullets name.
Do I still need a push mower for the edges?
Often, if the map stops short of a border, a pond gap, or a strip you excluded. The robot will not bag that strip. If the whole lawn was a twenty-minute push, buying both is a lot of money. Both make sense when the middle of a larger lawn is the robot’s job and the fringe is not.
