Review: Almost Perfect Battery Lawnmower - I've had this for about 3 weeks now, and have done 3 cuts, so decided to put my thoughts down. Like most I enjoy a good quality lawn, and since moving house two years ago our lawn in now about 10 metre square so ditching the old petrol push mower for the 33cm cut Ryobi made sense as I was already invested in the eco system. Pros: Lightweight and easy to maneuver Good cut depth range (25-65mm) - I use the lowest setting labelled as '1' Effective grass collection system Works with Ryobi and aftermarket batteries Quiet operation Cons: Battery life is limited (10-15 minutes) Expensive batteries Overall, the Ryobi 33cm One+ 18v lawn mower is a good choice for small to medium-sized lawns, don't even think about it for large lawns. It is lightweight and easy to maneuver, and it cuts grass evenly and effectively. The grass collection system is also effective, and the mower is relatively quiet. However, the battery life is limited, and Ryobi batteries are expensive. If you are looking for a cordless lawn mower that is affordable and easy to use, the Ryobi 33cm One+ 18v is a good option. I didn't see the major benefit for a small lawn to pay the extra for the larger cut model. Review: Easy to use, works fine, think about batteries - This is a perfect mower for small to medium sized lawns if you're already in the Ryobi One+ ecosystem. I already have other Ryobi tools and batteries and chargers, so this is a great improvement on my old corded mower, much less faffing around. However, if you have smaller batteries - the kind of thing you might use on a drill - it'll struggle with bigger mowing jobs (ie overgrown grass on a large lawn), you might have to swap batteries halfway through, or pause so they can cool down (I find that batteries reach their thermal limit before they're fully discharged). Even then it's less hassle than dragging a cable everywhere. I think most people would find that the lighter & easier mowing leads to them doing smaller mows more often, and in that case battery life probably isn't a problem. The lighter mower & lack of cable could make it easier to drop by and mow a relative's lawn, or a neighbour. Of course it's not cheap (and if you're buying official branded batteries it can get even more expensive), but for me it's worthwhile. If you're mowing a really big lawn, then maybe 2-stroke is still the way to go? ## Features - Compact Cutting Path: 33cm (13") cutting path designed for easy manoeuvrability around the garden - Cordless Battery Convenience: No potentially dangerous mains cable or messy petrol required for operation - Easy Edge Grass Comb Feature: Mow right to the perimeter without the need to finish it off with a grass trimmer - Adjustable Height and Handle: 5-Levels of cutting height (25-65mm) and 3-position telescopic handle for comfortable use - ONE+ System Compatibility: Part of the Ryobi ONE+ system with over 100 tools powered by one battery - Battery Coverage: Up to 250 m² coverage with an 18V ONE+ 5.0 Ah battery on a single charge - Lightweight Design: Weighs only 7.7kg without battery and features durable all-terrain wheels for easy manoeuvrability - Convenient Storage: Folding or removable handles allow for compact storage when not in use - Generous Grass Collection: 35L grass collector capacity with included mulching plug for versatile lawn care options - 5-Levels of cutting height (25-65mm) and 3-position telescopic handle ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PZXBTQ5 | | Battery Average Life | 45 minutes | | Best Sellers Rank | 2,875 in Garden ( See Top 100 in Garden ) 7 in Rotary Mowers 11 in Lawn Mower Parts & Accessories | | Brand | RYOBI | | Brand Name | RYOBI | | Colour | red | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 2,424 Reviews | | Cutting width | 33 Centimeters | | EU Spare Part Availability Duration | 5 Years | | Included Components | Garden & Landscaping Tools;Powered Lawnmowers - Electric;1641089030 - Lawn Mower Parts & Accessories | | Is Assembly Required? | No | | Item Dimensions D x W x H | 157.5D x 28.4W x 157.5H centimetres | | Item Type Name | 18V ONE+ Cordless 33cm Lawnmower (Body Only) | | Item Weight | 10.3 Kilograms | | Item weight | 10.3 Kilograms | | Manufacturer | Techtronic Industries (UK) | | Manufacturer Part Number | OLM1833B | | Manufacturer Warranty Description | 2 | | Material | Metal plastic | | Material Type | Metal plastic | | Maximum Adjustable Cutting Height | 65 Centimetres | | Minimum Adjustable Cutting Height | 25 Millimetres | | Model Number | OLM1833B | | Number of Positions | 3 | | Operation Mode | Automatic | | Power Source | Battery Powered | | Power source | Battery Powered | | Style | Lawnmower Only | | Style Name | Lawnmower Only | | Unit Count | 1.0 count | ## Product Details - **Brand:** RYOBI - **Colour:** red - **Cutting width:** 33 Centimeters - **EU Spare Part Availability Duration:** 5 Years - **Item weight:** 10.3 Kilograms - **Material:** Metal plastic - **Operation mode:** Automatic - **Power source:** Battery Powered - **Product dimensions:** 157.5D x 28.4W x 157.5H centimetres - **Style:** Lawnmower Only ## Images ![18V ONE+ OLM1833B 33cm Cordless Lawn Mower - Image 1](https://m.media-amazon.com/images/I/71z9kGBV9dL.jpg) ![18V ONE+ OLM1833B 33cm Cordless Lawn Mower - Image 2](https://m.media-amazon.com/images/I/81FlCmOf2GL.jpg) ![18V ONE+ OLM1833B 33cm Cordless Lawn Mower - Image 3](https://m.media-amazon.com/images/I/91HlTs7ML3L.jpg) ![18V ONE+ OLM1833B 33cm Cordless Lawn Mower - Image 4](https://m.media-amazon.com/images/I/81fHpmFCDmL.jpg) ![18V ONE+ OLM1833B 33cm Cordless Lawn Mower - Image 5](https://m.media-amazon.com/images/I/91nVSXUN8DL.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Questions & Answers **Q: Does it have a metal blade or plastic ?** A: metal **Q: what does "body only" mean** A: Body only means no battery and no charger. The idea of the ONE+ system is that you buy the battery and charger once and they can then power a range of different tools and appliances. **Q: Does the 'new version' fold for storage like the 'old version'?** A: Mine just arrived, and no it does not fold. There are bolts halfway down the handle you can unscrew, and bolts that hold it into the mower body that can be unscrewed, both with plastic handles so it is easy to do without tools, but it is not designed to fold. Also if you have clipped the cable to the handle you will need to unclip this to remove the handle. **Q: Is it very noisy compared to the Lawnmaster** A: Quiet ## Customer Reviews ### ⭐⭐⭐⭐⭐ Almost Perfect Battery Lawnmower *by S***E on 20 June 2023* I've had this for about 3 weeks now, and have done 3 cuts, so decided to put my thoughts down.

I was a bit hesitant from the mixed reviews and was torn between the 33cm and 40cm blade versions, I figured the larger blade version would make for a quicker job but the price difference was just daft so I bought the 33cm body only and snagged a third party backup battery from Amazon. First impressions, it was light, looked typically Ryobi, the lever to change cut depth is stiff and difficult to change. My lawn was at a ridiculous length and of reasonable size, it took the full charge of two batteries over the course of about 15-20 minutes. There's no warning battery is low but you'll know because the mower will stall at anything with more resistance than a fart in the wind. It's a learning process using a battery mower, what length is too too long for the settings and therefore cause a cut out but once you get the hang of it, the ease of cutting and the speed in which you can wizz around the lawn makes it worthwhile. It seems to do a good job, it's too early to comment on reliability but I've been using Ryobi one for over 10 years and my original tools still work great and original battery still going therefore I have faith in this little mower. The lever to change level and the rate at which it burns through batteries would be irritating unless you've got plenty of battery backups and a fast charger. Grab a few third party backup batteries and make sure you have at least two at full charge if doing a lawn of reasonable size. If doing more than one lawn then double your batteries and if this seems too much hassle then this mower isn't for you. Oh, and the assembly instructions are rubbish, luckily assembly is pretty logical and straight forward. Update: after 3 years of moderate use this lawn mower has lost it's electrical spark. Despite replacing my stock of batteries the mower will only operate for 5-10 minutes at a time indicating a motor issue, possibly overheating. I've now switched to a different brand (begins with w and ends with x) and had far superior results and hopefully the new mower will last more than 3 mowing seasons. ## Frequently Bought Together - Ryobi OLM1833B 18V ONE+ Cordless 33cm Lawnmower (Body Only), Anthracite/Green - Ryobi RB18L50 ONE+ Lithium+ 5.0Ah Battery, 18 V - Ryobi OLT1832 ONE+ Cordless Grass Trimmer, 25-30cm Path (Zero Tool), 18 V, Hyper Green (Battery, Charger And Blade Not Included) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/131349831-18v-one-olm1833b-33cm-cordless-lawn-mower](https://www.desertcart.us/products/131349831-18v-one-olm1833b-33cm-cordless-lawn-mower) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-05*
