If you've been searching for Hako cleaning equipment, you've probably come across two names: the Kodiak floor scrubber and the Renown floor scrubber. And if you've spent any time on the Hako website, you'll notice that both models have battery specs. But the real question isn't which number is bigger. It's how a machine fits into your shift, your building, and your tolerance for unplanned downtime.
I'm the person who gets called when a facility needs a scrubber yesterday. I've triaged floor cleaning emergencies for distribution centers, manufacturing plants, and hospitals for over a decade. In March 2024, I got a call at 2:30 PM from a warehouse that had a sanitation audit at 7 AM the next day. Their old scrubber had died mid-route. That's not the time to discuss theory. That's when you find out what actually matters about floor scrubber battery life.
There is no universal 'best' battery setup
Here's what I tell every customer: the answer depends on how long the machine is actually turned on, when you can recharge, and how tired your operator gets. Those three things separate a smart purchase from an expensive paperweight.
What most people don't realize is that published battery runtimes are based on a clean, flat floor at a constant speed. Real warehouses have racking corners, floor joints, slopes, and downtime. So the first thing I do is ignore the spec sheet and time the actual cleaning route.
That leads to the three situations I see most often. Figure out which one you're in, and the Kodiak vs Renown decision gets much easier.
Situation 1: Your daily scrubbing time is under 2.5 hours
If you run a fairly small facility, or you only scrub one section of the floor each day, you probably don't need the biggest battery Hako offers. I see this all the time with schools, retail stores, and small workshops. They often buy a larger machine because they think it's future-proof. In practice, that extra battery weight just makes the machine slower in the turns and harder to handle.
For this situation, I'd normally point you toward the Renown platform. The Renown is generally Hako's more compact scrubber option. It's available in different configurations, but the key point is: if your runs are short and you have an overnight charging window, a standard lead-acid battery is enough. You don't need lithium, and you don't need a high-capacity pack.
It's tempting to think a bigger battery always means more work gets done. But if your total active scrubbing is two hours, a machine that can run for four hours is already giving you 100% more buffer than you need. The extra cost is better spent on good charger maintenance or a spare squeegee blade.
Situation 2: You scrub for three to five hours in a continuous block
Large warehouses, food processing plants, and big-box retail stores are the classic examples here. The machine runs for hours, stops for lunch, then runs again. This is where the Kodiak platform starts to make sense. Kodiak tends to be Hako's larger, heavier-duty scrubber family, designed for long routes and operators who need a comfortable ride.
In this scenario, battery capacity is non-negotiable. You need enough for the full block, plus a buffer for unexpected interruptions. As a rule of thumb, I calculate the square footage of the cleaning area, divide by the machine's realistic cleaning rate, then add 30 minutes for turns, dump/refill stops, and squeegee checks. If that number is close to the battery's rated runtime, you need a bigger pack.
One thing I learned the hard way: the numbers aren't always about the machine itself. A few months ago, a client's numbers told us they needed a Kodiak with a high-capacity battery. My gut said something else was wrong. I checked their charging station and found an old underpowered charger that was only putting out about 70% of the rated amperage. We replaced the charger, and their existing battery started lasting an hour longer. Before you upgrade the battery, verify your charger is actually doing its job. That lesson saved them thousands.
If you're in this situation and you have a regular meal break, ask your Hako dealer about the lithium option. Lithium can absorb a 30-minute charge during lunch and give you a meaningful second boost. It's not cheap, but it can extend usable runtime without buying a second machine.
Situation 3: You need the scrubber across multiple shifts
This is the hardest scenario, and it's where I see the most mistakes. A 24/7 operation can't wait six to eight hours for a lead-acid battery to recharge. If you only have one machine and one battery, your scrubber is only available for one shift a day, no matter how highly the spec sheet rates it.
Here's the counterintuitive part: in multi-shift environments, a smaller machine with quick-cycle charging can beat a larger machine with a giant battery. Let me explain. A large battery extends runtime, but it also extends charge time. If you swap in a fresh battery at the shift change, the old one has a full day to recharge. That works with traditional lead-acid. If you choose lithium-ion, you can opportunity-charge during breaks. Either way, the machine becomes available for more hours of the day.
So if your operation runs 20 hours a day, I'd rather spec a Kodiak with a battery-swap program, or a Renown with two batteries, than a single larger scrubber with one huge pack. The largest pack in the world won't help you if the charger is only powered overnight.
What most people miss is that uptime is a charging problem, not just a runtime problem. You have to plan the whole ecosystem: battery, charger, spare batteries, and the shift schedule.
How to tell which scenario you're in
I'm not a battery engineer, so I can't speak to the chemistry inside each cell. What I can tell you from an operations perspective is how to figure out what you actually need.
- Time your current machine. Run it through a typical day and note how many minutes the brush is actually on the floor. Do this for three days and take the average.
- Map your recharge windows. You have an overnight window, a lunch window, or not. That single fact changes the battery type recommendation more than any other variable.
- Consider operator fatigue. If one person runs the machine all day, a ride-on Kodiak is easier than a compact Renown, even if the battery numbers look similar on paper.
- Check Hako's website for the fine print. The runtime numbers there are measured under specific conditions. As of early 2025, Hako publishes comparison charts that show the estimated runtimes for the Kodiak and Renown lines. Use those as a starting point, then apply the 80% rule.
If your active scrubbing time is under 2.5 hours, buy the simpler machine and save your budget. If it's over 4 hours, focus on high-capacity packs and charger quality. If you're running multiple shifts, don't buy a machine at all until you've designed the charging process.
The bottom line
Floor scrubber battery life isn't just a single number on a spec sheet. It's a schedule. The best machine for you is the one that's ready to work when your crew is ready to work.
I'd rather spend ten minutes helping you think through your own schedule than sell you the biggest machine we have. An informed customer asks better questions, and that's a lot easier than dealing with mismatched expectations later. If you're unsure, go to Hako's website, compare the Kodiak and Renown pages, and then talk to a dealer who will let you test the machine on your actual floor.
